A boy rolls a toy car across a floor with a velocity of 3.21 m/s. How long does it take the car to travel a distance of 4.50 m?
Mariana [72]

Answer:

Time taken for the car to travel a distance of 4.50 m = 1.40 seconds

Explanation:

velocity of toy car = 3.21 m/s

distance travelled by toy car = 4.50 m

Time = ?

Velocity = \frac{Distance}{Time} \\Time =\frac{Distance}{Velocity}

Time = \frac{4.50}{3.21} \\Time = 1.40s

Therefore, the time taken for the car to travel a distance of 4.50 m = 1.40 seconds

A student rapidly rubs the palms of both hands
Lapatulllka [165]

Answer:

Option a

Explanation:

The action of the rapid rubbing of the hands are a result of chemical reaction and responses that takes place inside our body.

When we rub our hands together, that shows the mechanical motion of the body or we can say that while rubbing hands chemical energy gets converted to mechanical energy (here, Kinetic energy).

While rubbing, due to friction, heat is produced and hence we can say that this mechanical energy has transformed to heat energy.

Thus the conversion here is from chemical to mechanical to heat energy.
