Answer:

a space station orbiting Earth

Explanation:

Kinetic energy in an object arises from the motion of the object.

$\frac {1}{2}\times m\times v^2$ is the kinetic energy of object.

(a) a person sitting on a couch while watching TV

The person is still and is not in motion and thus, do not exhibit any kinetic energy.

(b) an archer with a flexed bow

The archer hold the bow flexed. It may have a lot of potential energy but not kinetic energy as it is still.

<u>a space station orbiting Earth</u>

<u>The space station is moving and is in motion and thus, exhibits kinetic energy.</u>

The rock is on a mountain ledge . It may have a lot of potential energy but not kinetic energy as it is still.

(d) the high-energy phosphate bonds of a molecule of ATP

The bonds are still and is not in motion and thus, do not exhibit any kinetic energy.

Marizza181 [45]

The force on the clove will have the same magnitude but a negative sign with it that is F = - 14 N

<h3>What is force and how do we calculate it ?</h3>

The definition of force is: The pushing or pulling on a massed object changes its velocity. Force is an external agent that has the power to alter a body's resting or moving condition.

It has a size and a movement.

Newton's second law of motion defines the force formula as follows:

A force is equal to an object's mass times its acceleration, or F = m a. You must use SI units when applying this formula: kilograms for mass, meters per second squared for acceleration, and newtons for force.

What is the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind?

salantis [7]

We have that the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind is

X=0m/s

From the question we are told that

mosquito flying 2 m/s

against a 2 m/s headwind

Generally

The speed over the ground is the Flight Speed minus resistance speed

Generally the equation for the speed over the ground is mathematically given as

X=Flight Speed-resistance speed

Therefore

X=2-2

X=0m/s

When two oceanic plates converge, the plate with a greater density will subduct. This plate will partially melt, causing the for

N76 [4]

Answer:

Island arc

Explanation:

When two oceanic plates share a convergent type of plate boundary, the denser oceanic plate will subduct below the less dense oceanic plate. This will result in the formation of the subduction zone, where the rocks are being pulled down to the mantle. This subduction zone is typically marked by the presence of a narrow depression commonly known as an oceanic trench, that lies just above the zone.

The rocks of the subducting plate undergo partial melting and mix up with the magma that rises upwards towards the surface due to the force exerted by the convection currents. This later gives rise to the formation of volcanoes or a chain of volcanoes which are commonly known as an island arc.
