Explanation :
It is given that, a heavy box is in the back of a truck and the truck is accelerating to the right.
The description is shown in<em> figure 1</em>. Here, the forces that act on both box and the truck are the normal force, the frictional force and their weight mg.
The free body diagram is shown in <em>figure 2</em>. This shows the total forces ( F = ma )acting on the truck. As a result, the truck will move in a forward direction.
Hence, this is the required explanation.
Answer:
Explanation:
Depends on how hard you throw it.
Answer:
b. B, A, C
Explanation:
To solve this problem, let us find the net forces they are experiencing.
Net force = mass x acceleration
Object A; mass = 8kg and acceleration = 4m/s²
Net force = 8 x 4 = 32N
Object B; mass = 10kg and acceleration = 3m/s²
Net force = 10 x 3 = 30N
Object C: mass = 7kg and acceleration = 5m/s²
Net force = 7 x 5 = 35N
So, increasing order of their net force;
B < A < C
With "toward the wall" designated as the positive direction, the average acceleration felt the ball in the 0.0158 s of contact with the wall is
Answer:
Explained
Explanation:
Thickness coating= t
wavelength of light λ = 500 nm
2 t =(m+0.5)λ
Here m = 0
t= λ/4
= 500/4 nm
= 125 nm
= 125×10^(-9) m
