The latent heat of fusion of water is 344 j/p.This will take 344x300 or 100200 J to melt the ice. once it melted its at oc
Answer:
Vf=140 m/s
Vi=0
t=50s
Explanation:
1. Acceleration is called change of velocity.
2. a=Vf-Vi/t
a=140-0/50
a=140/50
a=2.8m/s^2
Answer:
A. Zero
Explanation:
The force on a coil of N turns, enclosing an area, A and carrying a current I in the presence of a magnetic field B, is :
F = N * I * A * B * sinθ
Where θ is the angle between the normal of the enclosed area and the magnetic field.
Since the normal of the area is parallel to the magnetic field, θ = 0
Hence:
F = NIABsin0
F = 0 or Zero
