Answer:
C. N/m (newtons/meter)
Explanation:
Since the equation for potential energy for a spring is PE = 1/2kx², after you know <em>k </em>and <em>x</em>, you will get an answer in Joules.
Please let me know if you want me to explain further!
Thanks!
Answer:the answer can be find out by the following steps;
Explanation:
Answer:
A. 4,440 N
Explanation:
A Force applied on an object with mass 'm' can change its velocity in a unit time. This change is called acceleration.
If a force 'F' is applied on a body of mass 'm', it produces an acceleration 'a' in the body.
Force is give as :
F = ma
In our case,
m = 1200 kg a = 3.7 m/s²
F = 1200 x 3.7
F = 4440 kgm/s²
F = 4440 N
Answer:
<em>7.45 10^5N.</em>
Explanation:
according to newtons second law of motion;
Fapp is the applied force
Fr is the resistive force
m is the mass of the luxury
a is the acceleration
Since the huge luxury liner move with constant velocity, then acceleration is zero i.e a = 0. The equation becomes;
This shows that the applied force will be equal to the resistive force if the velocity is constant.
Given Fr = 7.45 10^5 N therefore the resistive force will also be 7.45 10^5N.
<em>Hence the magnitude of the resistive force exerted by the water on the cruise ship is 7.45 10^5N.</em>
