Answer:
The pushing force and the skier's mass
(A) is correct option.
Explanation:
Given that,
Mass = 64 kg
Weight = 608 N
Velocity = 21 m/s
Forward force = 45 N
We need to calculate the reaction force of the snow pushing on the skier
Using given data,
The reaction force of the snow pushing on the skier is equal to the pushing force and the skier's mass.
Hence, The pushing force and the skier's mass
(A) is correct option.
Answer:
A big wheel with triple the circumference of a small wheel will rotate with triple the force.
Explanation:
- when this circumference is tripled, it means triple the force (they are directly correlated)
Answer:
Explanation:
2. The image formed in a diverging lens is always virtual.
4. Converging lenses are shaped such that a beam of parallel light rays passing through the lens will be brought together in one single point.
Technically, ALL of the planets do.
The effect is greatest inside Mercury, because Mercury is the one closest to the Sun.
