Answer: True
Explanation:
As the spring is compressed, it acumulates energy, and the spring "wants to release that energy". This acumulated energy, (potential energy) is called "elastic potential energy" because of the elastical nature of the spring, that when compressed it wants to return to the original shape. So the sentence is true
 
        
             
        
        
        
Answer:
786.6 N
Explanation:
mass of car, m = 912 kg 
initial velocity of car, u = 31.5 m/s 
final velocity of car, v = 24.6 m/ s 
time, t = 8 s 
Let a be the acceleration of the car 
Use first equation of motion 
v = u + a t 
24.6 = 31.5 + a x 8 
a = - 0.8625 m/s^2 
Force, F = mass x acceleration
F = 912 x 0.8625 
F = 786.6 N 
Thus, the force on the car is 786.6 N.

Explanation:
Now find the components NxNxN_x and NyNyN_y of N⃗ N→N_vec in the tilted coordinate system of Part B. Express your answer in terms of the length of the vector NNN and the angle θθtheta, with the components separated by a comma.
Vectors are quantities that  have both magnitude and direction while scalar quantities have only magnitude but no direction.
This a vector quantity
from the diagram the horizontal component of the length of the vector will be
 Ф
Ф
the vertical component will be
 Ф
 Ф
this is in the opposite direction because the x can be extrapolated to the negative axis
 
        
                    
             
        
        
        
The primary sex organs for men are called testes and ovaries for the women. They produce sex cells called gametes and they secrete sex hormones.
