A box experiencing a gravitational force of 600 N. is being pulled to the right with a force of 250 N. 825 N. frictional force a
lidiya [134]

Answer:A

Explanation:

Explanation:

Given that,

Gravitational force = 600 N

Frictional force = 25 N

Pulled by the Force = 250 N

We know that,

The gravitational force in downward and normal force act in upward. the frictional force in left side and the box pulled by the force to the right side.

The balance equation is along y-axis

The box will not move in y-axis therefore, the net force in the y-axis will be zero.

Hence, The net force in the y-direction will be zero.

"It is impossible to devise a process which may convert heat, extracted from a single
Vladimir [108]

Answer:

According to the second law of thermodynamics, we are unable to use the heat of the ocean and the atmosphere because we do not have a reservoir that has a temperature lower than the ocean or the atmosphere.

Explanation:

As you already know, the ocean and atmosphere have a lot of thermal energy, however, we are unable to convert this energy into mechanical energy that would be useful for our activities. This can be explained by the second law of thermodynamics, since it states that the presence of two bodies with different temperatures is necessary for it to be possible to transform heat into work.

In this case, to transform the thermal energy of the ocean and the atmosphere into mechanical energy we would need the existence of a thermal motor, which is only possible to be established when there is a body with high thermal energy and a sink, a reservoir, with low thermal energy, which will be the place where the heat will be expelled, to be converted into work. We do not have a reservoir with less thermal energy than the ocean and the atmosphere, so we cannot use their energy.

Before railroad were invented, goods often traveled along canals, with mules pulling barges from the bank. If a mule is exerting
morpeh [17]

Answer:

W = 112.76MJ

Explanation:

the work is:

W = F_xD

where F_x is the force executed in the direction of the displacement and the d the displacement.

so:

W = 12000Ncos(20)(10000)

we use the cos of the angule because it give us the proyection in the axis x of the force, that means the force in the direction of the displacement.

W = 112.76MJ

When sighting a firearm using an open sight, in what direction should the rear sight be moved if you want the shot to travel to
sattari [20]

Explanation:

Test to see where the bullets gather on your target after shooting a number of shots. Change the targets of your weapon if the bullets are not in the target's middle. Try to shift the rear view in the same direction with an open sight that you would like to push the shots on the target.

After the rifle is sighted-in, one must practice firing under various lighting and weather conditions, and at different distances to be able to become accurate and proficient shooter.
