The S wave vibrates both side to side and up and down whereas P wave is the first to arrive during an earthquake
Seismic waves during earthquake:During the eathquake, two types of seismic waves are generated , P wave and S wave.
The S waves produces vibrations to the ground in a shearing force perpendicular to the direction of propagation of the wave, moving the ground up and down or from side to side. S waves are called secondary waves because arrive after P waves.
The P waves is analogous to longitudinal vibrations, producing vibrations to the ground to compress and expand in the direction of propagation f the wave. They are called primary waves because they are the first type of wave to arrive at seismic recording stations.

A 50-g ball moving at 10 m/s in the +x direction suddenly collides head-on with a stationary ball of mass 100 g. If the collision is perfectly elastic, what is the velocity of each ball immediately after the collision?A. +6.7 m/s, -3.3 m/sB. -6.7 m/s, +3.3 m/sC. +3.3 m/s, -6.7 m/sD. -3.3 m/s, +6.7 m/s
Answer:
3.33m/sExplanation:
Using the law of conservation of momentum
m1u1 + m2u2 = (m1+m2)v
m1 and m2 are the masses of the object
u1 and u2 are the velocities
v is the final velocity
Given
m1 = 50g
u1 = 10m/s
m2 = 100g
u2 = 0m/s (stationary ball)
Required
Common velocity v
Substitute
50(10) + 100(0) = (50+100)v
500 = 150v
v = 500/150
v = 3.33m/s
Hence the velocity of each ball immediately after the collision is 3.33m/s

Explanation:
My solar system has two types of planets: terrestrials and jovians. The solar nebula hypothesis offers what explanation for the different compositions of these two types of planets? A. The large gravitational forces of Jupiter tended to prevent planet formation in the inner solar system and eventually attracted most of the material into the region of the Jovian planets. B. During condensation, the heavier elements tended to sink nearer the Sun and, being rare, only provided enough material to build the relatively small terrestrial planets. C. The terrestrial planets were formed near the Sun where, because of the high temperatures, only heavier elements were able to condense. D. During the collapse of the gaseous nebula, most of the material tended to collect far from the Sun because of the large centrifugal forces, which provided the necessary material to build the large Jovian planets.
Answer:
B. During condensation, the heavier elements tended to sink nearer the Sun and, being rare, only provided enough material to build the relatively small terrestrial planets.
D. During the collapse of the gaseous nebula, most of the material tended to collect far from the Sun because of the large centrifugal forces, which provided the necessary material to build the large Jovian planets.
Explanation:
The solar nebular hypothesis is the theory of how the earth came to be as proposed and believed by most scientists. It states that the solar system was formed from a nebular which is a large collection of dust. As the condensation of the nebular progressed, the heavier materials which could withstand higher temperatures formed closer to the sun. Because these materials were not so much the planets formed by them were not large in size.
However, the Jovian planets formed beyond the frost line which could sustain icy compounds. The ices that formed these planets were much thus accounting for their larger sizes. Solar winds blew off the lighter hydrogen and helium elements leading to their accumulation far away from the sun.

A small barge is being used to transport trucks across a river. If the barge is 10.00 m long by 8.00 m wide and sinks an additional 3.85 cm into the river when a loaded truck pulls onto it, determine the weight of the truck and load.
Answer:
30214 N
Explanation:
To start with, we solve this problem by applying Archimedes’ principle. We say that the weight of the truck and the weight of load is equal to the weight of the additional water displaced when the truck and the load moves onto the barge. Thus,
Volume of water displaced = 10.00 m * 8.00 m * 0.0385 m = 3.08 m³.
Density of water = 1000kg/m³
Mass of water displaced = volume * density
Mass of water displaced = 3.08 * 1000 = 3080 kg
Weight of water displaced (mg) = 3080 x 9.81 = 30214 N
Therefore, the Weight of truck + load = 30214 N

How much force is required to launch a 1 kg pumpkin 10 meters away from 5 meters off the
ground at a launch angle of zero degrees if it takes the catapult 0.1 seconds to fully launch the
pumpkin?
Answer:
F= 99 N
Explanation:
Dynamics and Kinematics
This problem is a combination of dynamics and kinematics because we need formulas and concepts of both branches of physics to solve it.
We need to calculate the force required to launch horizontally a pumpkin of m=1 Kg a distance of d=10 m away from a height of h=5 m.
Since the force is:
F = m.a
We need to calculate the acceleration required to move the pumpkin from rest (vo=0) to the launching speed (vf) in a time t=0.1 seconds.
The acceleration can be calculated by using the kinematic equation:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
The final launching speed vf can be calculated knowing the height and maximum horizontal distance reached by the pumpkin.
When an object is thrown horizontally with a speed vf from a height h, the range or maximum horizontal distance traveled by the object can be calculated as follows:
[tex]\displaystyle d=v_f\cdot\sqrt{\frac {2h}{g}}[/tex]
Solving for vf:
[tex]\displaystyle v_f=d\cdot\sqrt{\frac {g}{2h}}[/tex]
Substituting:
[tex]\displaystyle v_f=10\cdot\sqrt{\frac {9.8}{2\cdot 5}}[/tex]
Calculating:
[tex]v_f=9.9\ m/s[/tex]
Now we calculate the acceleration:
[tex]\displaystyle a=\frac{9.9-0}{0.1}[/tex]
[tex]a= 99\ m/s^2[/tex]
Thus, the force required is:
[tex]F=1\ Kg\cdot 99\ m/s^2[/tex]
F= 99 N
A jet plane flying 600 m/s experiences an acceleration of 4.0 g when pulling out of the circular section of a dive. What is the radius of curvature of this section of the dive?
Answer:
The radius is [tex]r = 9183.7 \ m[/tex]
Explanation:
From the question we are told that
The speed of the jet plane is [tex]v = 600 \ m/s[/tex]
The acceleration is [tex]a = 4g[/tex] here [tex]g = 9.8 \ m/s^2[/tex] so [tex]a = 4* 9.8 = 39.2 \ m/s^2[/tex]
Generally the centripetal acceleration of the jet just before it pulled out of the circular section dive is mathematically represented as
[tex]a = \frac{v^2}{r}[/tex]
=> [tex]r = \frac{v^2}{a}[/tex]
=> [tex]r = \frac{600^2}{39.2}[/tex]
=> [tex]r = 9183.7 \ m[/tex]
If a wind instrument, such as a tuba, has a fundamental frequency of 56.0 Hz, what are its first three overtones (in Hz)? It is closed at one end. (The overtones of a real tuba are more complex than this example, because it is a tapered tube.)
Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
[tex]f=\dfrac{nv}{4L}[/tex], n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
[tex]f_3=\dfrac{3v}{4L}\\\\=3\times \dfrac{v}{4L}\\\\=3\times 56\\\\=168\ Hz[/tex]
For second overtone, put n = 5
[tex]f_5=5\times f_1\\\\=5\times 56\\\\=280\ Hz[/tex]
For third overtone, put n = 7
[tex]f_7=7\times f_1\\\\=7\times 56\\\\=392\ Hz[/tex]
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
How does a magnetic field cause electric charges to form an electric current? O A. A force is exerted by the magnetic field on only the positive charges in the wire. B. Negative charges and positive charges are pushed in opposite directions by the magnetic field. C. A force is exerted by the magnetic field on only the negative charges in the wire. D. Negative charges and positive charges are pushed in the same direction by the magnetic field.
Answer:
Negative charges and positive charges are pushed in opposite directions by the magnetic field.
Explanation:
Just trust me.
The magnetic field causes electric charges to form an electric current which is responsible to push the positive and negative charges in the opposite direction because there is a magnetic field working as a magnetic effect of the electric current which results in negative charges and positive charges being pushed in opposite directions by the magnetic field. Therefore the correct option is B.
What is a magnetic field?A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted. The SI unit of the magnetic field is tesla.
The magnetic field is responsible for electric charges to form an electric current which results in pushing the positive and negative charges in the opposite direction.
There is a magnetic field working as a magnetic effect of the electric current which results in negative charges and positive charges being pushed in opposite directions by the magnetic field. Therefore the correct option is B.

If John throws a "ball” from a cliff with a speed of 15 m/s, how far from the bottom of the cliff does it land after 10 seconds?
Answer:
wazzam blood
Explanation:
The blood speed in a normal segment of a horizontal artery is 0.16 m/s. An abnormal segment of the artery is narrowed down by an arteriosclerotic plaque to one-eighth the normal cross-sectional area. What is the difference in blood pressures between the normal and constricted segments of the artery?
Answer:
The difference in blood pressures is [tex]P_1 -P_2 = 854.8 \ Pa[/tex]
Explanation:
From the question we are told that
The blood speed in a normal segment is [tex]v_1 = 0.16 \ m/s[/tex]
The area of the normal segment is [tex]A_1[/tex]
The area of the abnormal segment is [tex]A_2 = \frac{A_1}{8}[/tex]
Generally from continuity equation we have that
[tex]v_1 A_1 = v_2 A_2[/tex]
=> [tex]v_1 A_1 = v_2 * \frac{A_1}{8}[/tex]
=> [tex]0.16 = v_2 * \frac{1}{8}[/tex]
=> [tex]v_2 = 1.28 \ m/s[/tex]
Generally from Bernoulli's equation the difference in pressure is mathematically represented as
[tex]P_1 -P_2 = \frac{1}{2} \rho (v_2^2 - v_1^2 ) [/tex]
Here [tex]\rho[/tex] is the density of blood with value [tex]\rho = 1060 \ kg /m^3[/tex]
[tex]P_1 -P_2 = \frac{1}{2} (1060) ( 1.28 ^2 - 0.16 ^2 ) [/tex]
=> [tex]P_1 -P_2 = 854.8 \ Pa[/tex]

A mass of 1 kg is moving in a circle of radius 3.3 meters. What is the liner velocity v m/s that would give a Centripetal Force of 23 N?
Answer:
The linear velocity of the object is 8.71 m/s.
Explanation:
Given;
mass of the object, m = 1 kg
radius of the circle, r = 3.3 meters
centripetal force, F = 23 N
Centripetal force is given by;
[tex]F_c = \frac{mv^2}{r}\\\\[/tex]
where;
v is the linear velocity of the object
[tex]F_c = \frac{mv^2}{r}\\\\mv^2 = F_cr\\\\v^2 = \frac{F_cr}{m}\\\\v= \sqrt{\frac{F_cr}{m}} \\\\v= \sqrt{\frac{23*3.3}{1}}\\\\v = 8.71 \ m/s[/tex]
Therefore, the linear velocity of the object is 8.71 m/s.
