A=f/m
A=900/425
A=2.18
To determine acceleration you divide the force by the mass.
Answer: Rainfall and temperature can affect the rate in which rocks weather. High temperatures = more rainfall increasing the rate of chemical weathering. Rocks in tropical regions exposed to a lot of rainfall and hot temperatures weather faster than similar rocks in cold, dry climates.
Explanation:
Air can go in any direction. . .
Answer:

Explanation:
Given that
Radius of track = R
Radius of ball = r
The ball can be treated as solid sphere, so
The moment of inertia of ball

When the ball reach at the lowest position then it will have both angular and linear speed.
Condition for rolling without slipping v= ωr
Form energy conservation

v= ωr






Answer:
When an electrical current passes through a wire, a magnetic field is generated around it. Likewise, if the magnetic field around a wire is changed ( for example by rotating a coil inside a stationary manger), electricity will move through the wire.
