Answer:
v = 5.42 m/s
Explanation:
given,
height of the jumper = 1.5 m
velocity of sprinter = ?
kinetic energy can be transformed into potential energy




v = 5.42 m/s
Speed of the sprinter is equal to v = 5.42 m/s
You have learned your lesson well, Suhay. Your statement is correct.
The light rays from the fish BEND when they flow out of the water into the air. But our primitive brain still believes that the light rays flow STRAIGHT from the fish. The result is that the fish does not APPEAR to be at that place where it really is.
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
Answer:
Answer:
Bus travels 160 km in 4 hours
Speed of bus = 160/4 = 40 km/hr
Train travels 320 km in 5 hours
Speed of train = 320/5 = 64 km/hr
In one hour, bus travels 40 km and train travels 64 km.
Ratio = 40:64 = 5:8
