Answer:
B. decreases while his angular speed remains unchanged.
Explanation:
His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
yes
evaporation starts on the surface
Answer:
3000 newton force is required
Explanation:
F = ma
F= 1000 kgs x 3 m/s^ 2
F=3000(kgs x m/s^2)
F=3000 newton
