D is correct, Gamma rays have the shortest wavelength.
Answer:
1.7 m
Explanation:
= Velocity of ball in x direction = 4.47 m/s
= Velocity of ball in y direction = 0
g = Acceleration due to gravity = 
t = Time taken
= Vertical displacement = 0.7 m

Horizontal displacement is given by

The passenger should throw the ball 1.7 m in front of the bucket.
The answer for this question should be TRUE
Given that force is applied at an angle of 30 degree below the horizontal
So let say force applied if F
now its two components are given as


Now the normal force on the block is given as



now the friction force on the cart is given as



now if cart moves with constant speed then net force on cart must be zero
so now we have




so the force must be 199.2 N
