Answer:
35 kg
Explanation:
Given that,
Mass, [tex]m_1=35\ kg[/tex]
Mass of Venus, [tex]m_2=4.87\times 10^{24}[/tex]
Radius of Venus, [tex]r=6.05\times 10^{6}\ m[/tex]
We need to find the mass of the object on Earth.
Mass of an object is the amount of matter contained in it. It remains constant at every location. Here, the mass of the object is 35 kg on the Earth. It means its weight on Earth will remain the same i.e. 35 kg.
Hence, the correct option is (a).
[tex] \frac{1}{(1 - \sqrt{3) {}^{2} } } [/tex]
Answer:
\frac{2+\sqrt{3}}{2}
Explanation:
so we simplify tthe denominator first
[tex](1-\sqrt{3})^2=[/tex][tex]4-2\sqrt{3}[/tex]
so the new fraction is:[tex]\frac{1}{4-2\sqrt{3}}[/tex]
We'll ratinalize the fraction to get: [tex]\frac{2+\sqrt{3}}{2}[/tex]
The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. Which is NOT true about the role of the asthenosphere in plate tectonics?
Complete option to the question:
A. The asthenosphere is broken up into large continental- and ocean-sized plates.
B. Convection currents within the asthenosphere push magma upward to create new crust.
C. Heat from deep within Earth is thought to keep the asthenosphere malleable.
D. The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.
Answer: The correct option is A (The asthenosphere is broken up into large continental- and ocean-sized plates.)
Explanation:
Among the components that makes up the earth crust are the lithosphere and the asthenosphere.
The LITHOSPHERE is the outer layer of the earth structure which consists of the upper part of the mantle and the crust.
The ASTHENOSPHERE is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is denser and weaker layer of the upper mantle which permits the movement of tectonic plates in the lithosphere.
The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.Heat from deep within Earth is thought to keep the asthenosphere malleable. And the convection currents within the asthenosphere push magma upward to create new crust. But it is not broken up into large continental- and ocean-sized plates.

A large ball of Play-Doh with a mass of 0.04kg is launched from a catapult with an initial
speed of 5m/s and an
initial height of 1.0m. What is the final speed of the ball right before it strikes the ground? Draw a picture!
Answer:
≈ 6.68 m/s
Explanation:
A suitable formula is ...
vf^2 -vi^2 = 2ad
where vi and vf are the initial and final velocities, a is the acceleration, and d is the distance covered.
We note that if the initial launch direction is upward, the velocity of the ball when it comes back to its initial position is the same speed, but in the downward direction. Hence the problem is no different than if the ball were initially launched downward.
Then ...
vf = √(2ad +vi^2) = √(2·9.8 m/s^2·1.0 m+(5 m/s)^2) = √44.6 m/s
vf ≈ 6.68 m/s
The ball hits the ground with a speed of about 6.68 meters per second.

We assume the launch direction is either up or down.
In 1989 Carl Lewis established a world record when he ran the hundred meter dash in 9.92 seconds. What was his average speed (in M/S) for the race? Remember to include your data, equation, and work on solving the problem.
Answer:
10.08 m/s
Explanation:
The average speed of a body or an object can be calculated from the ratio of the total distance traveled by the body/object to that of the time taken to cover the distance.
Mathematically,
Average speed = total distance/total time
The total distance covered by Carl Lewis = 100 m
The total time taken = 9.92 s
Hence,
Average speed of Carl Lewis = 100/9.92
= 10.08 m/s

Explanation:
A horizontal pipe contains water at a pressure of 110 kPa flowing with a speed of 1.4 m/s. When the pipe narrows to one half its original diameter, what is (a) the speed and (b) the pressure of the water?
Answer:
a
[tex]v_2 = 5.6 \ m/s[/tex]
b
[tex]P_2 = 80600 \ Pa[/tex]
Explanation:
From the question we are told that
The pressure of the water in the pipe is [tex]P_1= 110 \ kPa = 110 *10^{3 } \ Pa[/tex]
The speed of the water is [tex]v_1 = 1.4 \ m/s[/tex]
The original area of the pipe is [tex]A_1 = \pi \frac{d^2 }{4}[/tex]
The new area of the pipe is [tex]A_2 = \pi * \frac{[\frac{d}{2} ]^2}{4} = \pi * \frac{\frac{d^2}{4} }{4} = \pi \frac{d^2}{16}[/tex]
Generally the continuity equation is mathematically represented as
[tex]A_1 * v_1 = A_2 * v_2[/tex]
Here [tex]v_2[/tex] is the new velocity
So
[tex]\pi * \frac{d^2}{4} * 1.4 = \pi * \frac{d^2}{16} * v_2[/tex]
=> [tex]\frac{d^2}{4} * 1.4 = \frac{d^2}{16} * v_2[/tex]
=> [tex]d^2 * 1.4 = \frac{d^2}{4} * v_2[/tex]
=> [tex]1.4 = 0.25 * v_2[/tex]
=> [tex]v_2 = 5.6 \ m/s[/tex]
Generally given that the height of the original pipe and the narrower pipe are the same , then we will b making use of the Bernoulli's equation for constant height to calculate the pressure
This is mathematically represented as
[tex]P_1 + \frac{1}{2} * \rho * v_1 ^2 = P_2 + \frac{1}{2} * \rho * v_2 ^2[/tex]
Here [tex]\rho[/tex] is the density of water with value [tex]\rho = 1000 \ kg /m^3[/tex]
[tex]P_2 = P_1 + \frac{1}{2} * \rho [ v_1^2 - v_2^2 ][/tex]
=> [tex]P_2 = 110 *10^{3} + \frac{1}{2} * 1000 * [ 1.4 ^2 - 5.6 ^2 ][/tex]
=> [tex]P_2 = 80600 \ Pa[/tex]

On a sunny summer day, why does a white car with a light-colored interior stay cooler than a black car with a dark-colored interior?
Solar radiation reflects off the lighter colours, away from the car, thus keeping the car cool
Solar radiation is absorbed into the lighter colours, keeping the car cool
Solar radiation is absorbed into the darker colours, keeping the car cool
Solar radiation reflects off the darker colours, away from the car, thus keeping the car cool
Answer: Solar radiation reflects off the lighter colours, away from the car, thus keeping the car cool
Explanation: This is because lighter colors reflect a good amount of radiation while darker colors absorb it. Just like, Antarctica hasn't completely melted because it reflects a lot of the heat that is acting upon it. Or, you notice that you get hotter when you wear a black shirt opposed to a white one.
The opening to a cave is a tall, 30.0-cm-wide crack. A bat is preparing to leave the cave emits a 30.0 kHz ultrasonic chirp. How wide is the "sound beam" 100. M outside the cave opening? Use v sound= 340. M/s.
Answer:
The value is [tex]w = 7.54 \ m[/tex]
Explanation:
From the question we are told that
The length of the crack is [tex]a = 0.3 \ m[/tex]
The frequency is [tex]f = 30.0 \ kHz = 30 *10^{3} \ Hz[/tex]
The distance outside the cave that is being consider is [tex]D = 100 \ m[/tex]
The speed of sound is [tex]v_s = 340 \ m/s[/tex]
Generally the wavelength of the wave is mathematically represented as
[tex]\lambda = \frac{v}f}[/tex]
=> [tex]\lambda = \frac{340 }{30*10^{3}}[/tex]
=> [tex]\lambda = 0.0113 \ m/s[/tex]
Generally for a single slit the path difference between the interference patterns of the sound wave and the center is mathematically represented as
[tex]y = \frac{ n * \lambda * D}{a}[/tex]
=> [tex]y = \frac{ 1 * 0.0113 * 100}{0.3}[/tex]
=> [tex]y = 3.77 \ m[/tex]
Generally the width of the sound beam is mathematically represented as
[tex]w = 2 * y[/tex]
=> [tex]w = 2 * 3.77[/tex]
=> [tex]w = 7.54 \ m[/tex]
A billiard ball traveling at 4m/s has an elastic head-on collision with a billiard ball of equal mass that is initially at rest. The first ball is at rest after the collision. What is the speed of the second ball after the collision?
Answer:
The speed is 4m/s because the size is the same.
Explanation:
The speed of the second ball after the collision is 4 m/s.
What is law of conservation of momentum?According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.
Let the mass of each billiard ball is m.
Before collision speed of first billiard ball: u = 4 m/s.
Before collision speed of second billiard ball: U= 0 m/s.
After collision speed of first billiard ball: v = 0 m/s.
After collision speed of second billiard ball: V= ?
From conservation of momentum, we can write:
Total momentum before collision = Total momentum after collision
mu +M.0 = m.0 + m.V
u = V
V = 4 m/s.
The speed of the second ball after the collision is 4 m/s.

When light is directed on a metal surface, the kinetic energies of the photoelectrons a) are random b) vary with the frequency of the light c) vary with the intensity of the light d) vary with the speed of the light
Answer:
b) vary with the frequency of the light
Explanation:
The phone electric effect can be expressed as
K.E=(hv -W•)
Where K.E is the Kinectic energy
W• = work function of the metal
ν =frequency of the radiation
h = Planck's constat
Then, we can see that K.E is proportional linearly to "v" in the equation above.
Therefore, When light is directed on a metal surface, the kinetic energies of the photoelectrons vary with the frequency of the light
