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.
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]

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

4.2 x 10⁵kg
Explanation:
Given parameters:
Speed of orbit = 7660m/s
Kinetic energy = 1.24 x 10¹³J
Unknown:
Mass = ?
Solution:
Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;
K.E = [tex]\frac{1}{2}[/tex]mv²
m is the mass
v is speed
Now insert the parameters and find the mass;
1.24 x 10¹³ = [tex]\frac{1}{2}[/tex] x m x 7660²
1.24 x 10¹³ = 2.93 x 10⁷m
m = [tex]\frac{1.24 x 10^{13} }{2.93 x 10^{7} }[/tex] = 0.42 x 10⁶kg = 4.2 x 10⁵kg

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

Is a ball standing still potential or kinetic?
PLEASE HELP!!!!
On his quest to find a shrubbery for the "Knights Who Say Ni!", King Arthur rides his horse off a 15m cliff and lands 4.3m away.
What was his original horizontal velocity?
Answer:
v = 2.45 m/s
Explanation:
first we find the time taken during this motion by considering the vertical motion only and applying second equation of motion:
h = Vi t + (1/2)gt²
where,
h = height of cliff = 15 m
Vi = Initial Vertical Velocity = 0 m/s
t = time taken = ?
g = 9.8 m/s²
Therefore,
15 m = (0 m/s) t + (1/2)(9.8 m/s²)t²
t² = (15 m)/(4.9 m/s²)
t = √3.06 s²
t = 1.75 s
Now, we consider the horizontal motion. Since, we neglect air friction effects. Therefore, the horizontal motion has uniform velocity. Therefore,
s = vt
where,
s = horizontal distance covered = 4.3 m
v = original horizontal velocity = ?
Therefore,
4.3 m = v(1.75 s)
v = 4.3 m/1.75 s
v = 2.45 m/s

A certain superconducting magnet in the form of a solenoid of length 0.56 m can generate a magnetic field of 6.5 T in its core when its coils carry a current of 80 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find the number of turns in the solenoid.
Answer:
The value is [tex]N =36203 \ turns[/tex]
Explanation:
From the question we are told that
The length of the solenoid is [tex]l = 0.56 \ m[/tex]
The magnetic field is [tex]B = 6.5 \ T[/tex]
The current is [tex]I = 80 \ A[/tex]
The desired temperature is [tex]T = 4.2 \ K[/tex]
Generally the magnetic field is mathematically represented as
[tex]B = \frac{\mu_o * N * I }{L }[/tex]
=> [tex]N = \frac{B * L }{\mu_o * I }[/tex]
Here [tex]\mu_o[/tex] is the permeability of free space with value
[tex]\mu_o = 4\pi * 10^{-7} N/A^2[/tex]
So
[tex]N = \frac{6.5 * 0.56 }{ 4\pi * 10^{-7} * 80 }[/tex]
=> [tex]N =36203 \ turns[/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.
