Answer:
Social, physical behavior
Explanation:
The relational aggression is the aggression which caused or give to person by doing harm to his or her relationship or social image.
Reactive aggression is the aggression which is caused by threatening someone, or caused by provocation, or caused due to frustration.
Therefore, the basic differentiation in between both the aggression is that relational aggression is caused by by damaging social status whereas reactive aggression is caused through physical behavior.
Net force is basically the force an object has when changing direction, so the answer would be D.
<span>On the scale the only external forces are the man's weight acting downwards and the normal force which the scale exerts back to support his weight.
So F = Ma = mg + Fs
The normal force Fs (which is actually the reading on the scale) = Ma + Mg
But a = 0
So Fs = Mg which is just his weight.
Fs = 75 * 9.8 = 735N</span>
Answer:
t = 1.16 s.
Explanation:
Given,
speed of conveyor belt, v = 3.2 m/s
coefficient of friction,f = 0.28
Using newton second law
f = ma
and we also know that frictional force
f = μ N
f = μ m g
equating both the force equation
a = μ g
a = 0.28 x 9.81
a = 2.75 m/s²
Using Kinematic equation
v = u + at
3.2 = 0 + 2.75 x t
t = 1.16 s.
Time taken by the box to move without slipping is 1.16 s.
