Answer:

Correct Answer is B (Differences in temperature)

Explanation:

One of the main cause of ocean current to occur is variation of temperature of different layer of oceanic water.Water which have high temprature is less dense and this Less density water float above the surface of high density water. When this less density water reached on the surface of ocean that time wind which blows on the surface water makes the water cool or in other words we can say that water released its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water will moves upward. In this way this process will continue and hence ocean current is created.

Why can't heat be transferred between two objects that have the same temperature

Inessa [10]

Answer: Because temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are the same temperature.

Suppose you start an antique car by exerting a force of 258 N on its crank for 0.270 s. What angular momentum is given to the en

gulaghasi [49]

Answer:

69.66 rad/s

Explanation:

Suppose the handle of the crank is L = 1 m long. We can calculate the torque:

T = F*L = 258*1 = 258 Nm

Then the angular momentum is given to the handle within 0.27 seconds is

$M_{\alpha} = T*t = 258*0.27 = 69.66$ rad/s

A ball thrown by Ginger is moving upward through the air. Diagram A shows a box with a downward arrow. Diagram B shows a box wit

vichka [17]

As the ball is moving in air as well as we have to neglect the friction force on it

So we can say that ball is having only one force on it that is gravitational force

So the force on the ball must have to be represented by gravitational force and that must be vertically downwards

So the correct FBD will contain only one force and that force must be vertically downwards

So here correct answer must be

Diagram A shows a box with a downward arrow.

What causes the tail of a comet to become visible?

nlexa [21]

Answer:

The correct answer is option C. Sun.

Explanation:

The tail of a comet as well as the comma are visible thanks to the influence of sunlight on these objects.

If there is a case that these objects cross the inner Solar System, then they will be visible from Earth. The reason why this occurs is that as the comet approaches the internal solar system, the materials that are inside the comet vaporize and flow out of the nucleus thanks to solar radiation, and while they do carry dust with them.

This dust is the one that reflects sunlight directly, while the gases shine because of ionization.

Usually we will need a telescope to see a comet, although there are some that can be seen with the naked eye.
