Other

The answer to your question is the letter D) 10 m/s

Explanation:

Data

distance = 100 m

time = 10 s

velocity = ?

Definition. Velocity is the rate of change of distance with respect to time.

Formula

              Velocity = distance / time

-Substitution

              Velocity = 100 / 10

-Simplification

              Velocity = 10 meters/second

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
