Answer:Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards.
Explanation:
A quick, easy way to decide whether there was a chemical change
is to look and see whether there are NEW substances after the
event, that weren't there when it started.
This particular scenario started out with fat and sodium hydroxide (lye).
And then, suddenly, POOF ! Soap and glycerin showed up. Where did
THOSE come from ? They came from the molecules in fat and lye,
getting broken up and recombined to make different substances.
THAT's exactly a chemical change.
Answer:
Distance covered to top of the hill was : 1.755 km
Explanation:
Initial velocity = 35 km/hr
Acceleration = 2.0 km/hr²
Time taken to accelerate = 3 minutes = 3/60 hours = 1/20 hours
Formula for acceleration : a = Δv /t
v-u/t ---where u is initial velocity , v is final velocity and t is time taken for acceleration
v- 35 / 0.05 = 2
v = 35.10 km/h
Formula for distance is product of speed and time
Distance covered = 35.10 * 0.05 = 1.755 km
