Answer:
the motion of the coin taping the balloon is the balloon squshing down
The spectrum of light from a star will have dark bands in it. These dark bands can be used to determine what atoms are in the star's atmosphere, and hence what it is made of.
According to Newton's 3rd law of motion, every action has an equal and opposite reaction.
So Wall must apply a force of 50 Newton but in opposite direction.
Hope you got it :-D
Answer:
Distance
Speed = ----------------
Time
Distance/Displacement
1.5m/s = ------------------------------------------
10s
Distance
1.5m/s × 10 = --------------------- × 10
10s
(Get rid of the fraction by multiplying it by the denominator in this case 10)
15m = Distance
Distance and Displacement are almost the same thing regarding this question. But watch out when you doing other questions and when you have initial velocity and initial time.
Displacement is 15m.
