Answer:
gravity, friction, opposite, friction. hope that helps :)
Explanation:
I think that your answer should be D) the state should make use of satellites and radars because they detect when a storm is coming
The object will remain at rest
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Here net force is zero
An object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
F=MA
Force F=0
Than Acceleration A=0
With zero Acceleration stationary object will remain at rest.
Hence Remain at rest is the correct answer

1)the edges where two plates meet are plate boundaries.
2)a sudden slip on a fault triggers an earthquake as stress in the edge overcomes the tension that releases energy into waves that move through the surface of the earth and cause a shake.
3)motion of the ground, aftershocks, shuddering, trembling, wobbling, crashing, falling, breaking, and more
4) the outer layer of Earth is the crust (lithosphere) which is made up of hot molten rock and granite.
The potential energy of the block is given by:
V = m*g*h
m mass
g = 9.81m/s²
h height
The potential energy of a spring is given by:
V = 0.5 * k * x²
k spring constant
x compression of the spring
If the block starts from rest it has potential energy, but no kinetic energy. As it slides down the incline potential energy is converted into kinetic energy. When the block hits the spring the kinetic energy is converted into spring's potential energy. If the spring is fully compressed and the block is at rest again, the block has transferred all its energy into the spring. No energy is lost. So we can write:
m * g * h = 0.5 * k * x²
m = 0.5 kg
g = 9.81 m/s²
h = 2.5m * sin 37° = 1,5 m
x = 0,6 m
Solve for k.
k = 2 * m * g * h / x² = 40.8 N/m
