Answer:
100 m / s^
F =ma from this divided F and ma by m to get acceleration
a = F / m
a = ?
F = 5 N
m = 50 g = 0. 0 5 kg ; if 1 kg = 1000g how much kg of 50 g by criss cross method we get 0.05 kg
so; 5N / 0. 05 kg = 5kg m / s^ / 0.05 kg
kg cancel by kg
the result is 100 m/ s^
Recall that
At its maximum height 
, the toy will have 0 vertical velocity, so that
For the toy to reach this maximum height, it takes time 
such that
which means it takes twice this time, i.e. 
, for the toy to reach its original position.
The velocity of the toy when it falls 1.0 m below its starting point is
where we took the negative square root because we expect the toy to be moving in the downward direction.
Answer:proton as they bear positive charge and located at the nucleus
Answer:
The answer is below
Explanation:
i) Since the length of the second clock (radius) is 14 cm = 0.14 m, the distance covered by the second hand in one revelution is:
Distance covered = 2πr = 2π(0.14) = 0.88 m
The time taking to complete one revolution = 60 seconds, hence;
Speed = distance covered in one revolution / time take o complete a revolution
Speed = 0.88 m / 60 s = 0.0147 m/s
ii) Distance covered in 150 s = speed * 150 s = 0.0147 * 150 = 2.2 m
iii) Displacement in 150 seconds = distance from initial position to final position
At 150 s, the hand has covered 2 revolutions and moved 30 s. Hence:
Displacement in 150 seconds = speed * 30 s = 0.0147 * 30 = 0.44 m
