Answer:

207Nm

Explanation:

Work on said to be done when an applied force causes an object to move through a particular distance. mathematically,

Work done = Force(f)×distance in the direction of force.

Given force of gravoty = 45N

Height = corresponding Distance= 4.6m

Work done = 45×4.6

Work done= 207Nm

This shows that 207Nm of work is done by the force of gravity when a 45 N object falls to the ground from a height of 4.6 m.

Oksi-84 [34.3K]
Force is the product of mass and acceleration .
The question is ask to find acceleration.
But acceleration is the ratio of the force and the mass.
where 600kg is the mass and 7kN is the force
NB: kilo is 1000
now we have to multiply 7N by 1000
by doing so you will have 7000N
which is the force.
Now to find the acceleration: force/ mass
which is 7000/600
therefore the maximum acceleration is 11.667

Increasing the concentration of greenhouse gases in Earth's atmosphere decreases the transparency of the atmosphere to infrared
kondaur [170]

Answer:

Decreases the transparency of the atmosphere to infrared light.

Explanation:

When a large amount of green-house gases are present in the atmosphere, the layer of these gases become opaque to infrared radiation and radiation from the sun get trapped into these gases molecules. These excited molecules radiate this energy into our own atmosphere and that why the temperature of Earth is rising due to the Green-House effect.
