1. Has to be a very large bathtub or very, very small supertanker
2. The car hit harder because the bug is not going anywhere near the same speed as the car, therefore it is not exerting the same force.
3. It's so fast it's hard to put a number on it and and it depends on the think Es of wire, distance from wall, and which type of T.V. (because if it requires less electricity then the electrons will travel slower)
4. The ball being thrown, because when and object is thrown and then falls, it always falls at a greater speed then those just being dropped.
Combustion is the process of burning something
A pulsar is a type of neutron star that rotates <span>very rapidly and emits electromagnetic radiation. The correct option among all the options that are given in the question is the last option or the third option. I hope that this is the answer that has actually come to your desired help.</span>
Answer:
θ = 13.16 °
Explanation:
Lets take mass of child = m
Initial velocity ,u= 1.1 m/s
Final velocity ,v=3.7 m/s
d= 22.5 m
The force due to gravity along the incline plane = m g sinθ
The friction force = (m g)/5
Now from work power energy
We know that
work done by all forces = change in kinetic energy
( m g sinθ - (m g)/5 ) d = 1/2 m v² - 1/2 m u²
(2 g sinθ - ( 2 g)/5 ) d = v² - u²
take g = 10 m/s²
(20 sinθ - ( 20)/5 ) 22.5 = 3.7² - 1.1²
20 sinθ - 4 =12.48/22.5
θ = 13.16 °
