Answer:Yes
Explanation:
Yes, there will be a force of gravity acting on the Pencil but it will hover in front of the person because lift would itself having free fall.
Free is the state of body where gravity is the only force acting on the body while it is falling from a height.
According to the theory of relativity, a body under free fall has no force acting on it.
Anything inside the lift will be experiencing the free fall as they are falling under the influence of gravity completely.
Explanation:
Given parameters:
Distance = 180m
Time = 12s
Unknown:
Speed in m/s and km/hr
Solution:
Speed is the distance divided by the time taken,
Speed = 
So;
Speed = 
= 15m/s
1000m = 1km
3600s = 1hr
Therefore;
15 x m x 
x 
x 
= 54km/hr
Answer:
1. friends getting you to study
2. leading you to make the right decision
3. giving you advice pushing you towards whats right
4. pressuring you to be a good person
5. telling you when in the wrong
Explanation:
all of these are ways of positive peer pressure
mass of the box = 20 kg
force of friction on the box due to surface
similarly kinetic friction on it
now the weight of the suspended block will be
so here the weight of the suspended block is less than the limiting friction on it
So here we will say that friction will counter balance the weight of the suspended block and it will not move at all
So acceleration of the box will be zero
No because if there is a force, there is acceleration which means the object is getting faster.
