The answer is Monocline. And I checked it, it's correct.
The acceleration due to gravity of the planet X is 1 m/s².
The given parameters;
- height above the ground, h = 100 m
- initial velocity of the rock, u = 15 m/s
- time of motion of the rock, t = 10 s
The acceleration due to gravity is calculated as follows;
![h = ut - \frac{1}{2} gt^2\\\\100 = 15(10) - (0.5\times 10^2)g\\\\100 = 150 - 50g\\\\50g = 150-100\\\\50g = 50\\\\g = 1 \ m/s^2](https://tex.z-dn.net/?f=h%20%3D%20ut%20-%20%5Cfrac%7B1%7D%7B2%7D%20gt%5E2%5C%5C%5C%5C100%20%3D%2015%2810%29%20-%20%280.5%5Ctimes%2010%5E2%29g%5C%5C%5C%5C100%20%3D%20150%20-%2050g%5C%5C%5C%5C50g%20%3D%20150-100%5C%5C%5C%5C50g%20%3D%2050%5C%5C%5C%5Cg%20%3D%201%20%5C%20m%2Fs%5E2)
Thus, the acceleration due to gravity of the planet X is 1 m/s²

Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere.
Answer:
![speed= 12.15\frac{m}{s}](https://tex.z-dn.net/?f=speed%3D%2012.15%5Cfrac%7Bm%7D%7Bs%7D)
Explanation:
In this question we have given
mass of airplane=.6 Kg
Radius of horizontal circle,r=6m
Time taken to complete 1.6 revolution=5s
Therefore time taken to complete 1 revolution, t=![\frac{5}{1.6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B1.6%7D)
t=3.1 s
We have to find the speed of airplane
We will first find the distance covered by airplane in tracing one circle which is equal to circumference of circle
We know that
Circumference,d = ![2 \pi \times r](https://tex.z-dn.net/?f=2%20%5Cpi%20%5Ctimes%20r)
or ![d=2\times 3.14 \times 6](https://tex.z-dn.net/?f=d%3D2%5Ctimes%203.14%20%5Ctimes%206)
![d=37.68 m](https://tex.z-dn.net/?f=d%3D37.68%20m)
We know that speed=
............(1)
Put value of d and t in equation 1
speed=![\frac{37.68}{3.1}](https://tex.z-dn.net/?f=%5Cfrac%7B37.68%7D%7B3.1%7D)
![speed= 12.15\frac{m}{s}](https://tex.z-dn.net/?f=speed%3D%2012.15%5Cfrac%7Bm%7D%7Bs%7D)
The mass of the ball is 1.55 kg and its change in momentum is 10 kgm/s.
<h3>What is momentum of a body?</h3>
The momentum of a body is the product of the mass and velocity of the body.
- Momentum = mass * velocity
Mass of the ball = momentum/velocity
Mass of the ball = 3.29 / 2.11 = 1.55 kg
The change in momentum of the body or Impulse = force * time
Change in momentum of the body = 5.00 * 2.00 = 10 kgm/s
Therefore, the momentum of a body depends on its mass and velocity.
