Answer:
Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
Explanation:
Answer:
Magnification will be equal to 3
Explanation:
We have given focal length of the converging lens
Focal length of the diverging lens
Object is placed 40 cm to the length of the converging lens d = 40 cm
Combination of the focal length will be equal to
F = 60 cm
So combination of the focal length will be 60 cm
Magnification is given by
So magnification will be equal to 3
300 miles / 6 hours = 50 miles per hour
The liquid is called condensation and its generally formed when water vaor in the air cools down rapidly and collects around or on an object forming water droplets.
Light travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and cameras detect light.
