I think that the girl has greater tangential acceleration because she is closer to the center and the acceleration is greater there.
Answer:
Energy is:
A property that must be transferred to perform work.
The variables that show a direct relationship are :
- The speed of a car and the distance traveled
- Number of students in a cafeteria and the amount of food consumed
- The distance a planet is from the sun and that planet's temperature
- The mass of a space shuttle and its acceleration through space
In direct relationship, when one factor is increased/decreased , it will directly cause the other factor to be increased/decreased
The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
- <em>mass of the cart, m = 1 kg</em>
- <em>work done on the cart, W = 5 J</em>
- <em>initial velocity of the cart, u = 3 m/s</em>
The distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
The final velocity of the cart is calculated as follows;
Thus, the final velocity of the cart at the given mass is 4.36 m/s.

Answer:
0.0106 m
Explanation:
We have given that the frequency of the radar signal is
Velocity of light
We know that velocity = wavelength ×frequency
So
So wavelength of the radar signal will be 0.0106 m
