Answer:
time = 8.3333 minutes.
Explanation:
distance between earth and sun = 1.5 *
speed of light = 3*
convert the distance unit from km to m so we can have uniform units.
distance between earth and sun = 1.5 *m
distance between earth and sun = 1.5 * m
speed = distance /time
time = distance / speed
time =
time =500 sec
time = 500/60 minutes
time = 8.3333 minutes.
Answer:
10 kg
Explanation:
Assuming a frictionless surface, then force F=ma where F is the applied force, m is the mass and a is acceleration. Making m the subject of the formula then
Substituting 100 N for the applied force F and 10 m/s^2 for acceleration a then the value of m will be
Therefore, in terms of kilograms, the bookshelf weighs 10 Kg
