Answer:
a force
Explanation:
Because if we apply force then only an object can slow down, speed up or change direction
 
        
                    
             
        
        
        
Answer:
Explanation:
In this case, law of conservation of energy will be implemented. It states that "the energy of the system remains conserved until or unless some external force act on it. Energy of the system may went through the conversion process like kinetic energy into potential and potential into kinetic energy.But their total always remain the same in conserved systems."
Given data:
Height of tower = 10.0 m
Depth of the pool = 3.00 cm
Mass of person = 61.0 kg
Solution:
Initial energy = Final energy

As the person was at height initially so it has the potential energy only.



Lets find out the magnitude of the force that the water is exerting on the diver.
W =ΔK.E


F = 1992.67 N
 
        
             
        
        
        
Answer:
The kinetic energy of the particle as it moves through point B is 7.9 J.
Explanation:
The kinetic energy of the particle is:
 
 
<u>Where</u>:
K: is the kinetic energy
 : is the potential energy
: is the potential energy
q: is the particle's charge = 0.8 mC
ΔV: is the electric potential = 1.5 kV                                    
 
 
Now, the kinetic energy of the particle as it moves through point B is:


Therefore, the kinetic energy of the particle as it moves through point B is 7.9 J.

Answer:
Option C. 
Impulse = mass × change in velocity 
Explanation:
Impulse is defined by the following the following formula:
Impulse = force (F) × time (t)
Impulse = Ft
From Newton's second law of motion,
Force = change in momentum /time
Cross multiply 
Force × time = change in momentum
Recall:
Impulse = Force × time 
Thus, 
Impulse = change in momentum
Recall:
Momentum = mass x velocity 
Momentum = mv
Chang in momentum = mass × change in velocity 
Change in momentum = mΔv 
Thus, 
Impulse = change in momentum
Impulse = mass × change in velocity
