Answer:
the balls would move closer to each other
Explanation:
Answer:
different poles
Explanation:
different poles attract to each other while same poles repel each other . just remember the old saying opposites attract and likes repel .
This is a boating question not really a physics questions, but googling the rules says the motorboat is the stand on vessel. The pwc is, by class, lighter than the motorboat so it has more maneuverability and thus should be the one to change course. The motorboat is the stand on vessel, so it keeps it's course and speed unchanged.
Answer:
The forces could be gravity, friction between the car and the ground, the force Katie is applying and the normal reaction.
Answer:
L_new =L+x^2 = L_new = 0.54_m.
Explanation:
Given data:
Force in the first case,
F_1 = 5N
Force in the second case,
F_2 = 20 N
Natural length of spring,
L= 0.5
Extension in the first case,
x_1 = 0.01m
Let the force constant of the spring be k.
Thus,
F_1=kx_1
5 = k × 0.01
⇒ k = 500 N/m.
The extension in the spring in the second case can be given as,
F_2=kx_2
20 = 500x_2
⇒ x_2 = 0.04 m.
Thus, the effective length of the spring would be,
L_new =L+x^2
L_new = 0.5+0.04
L_new = 0.54_m.
