Answer : Experimental

Explanation : We investigates by the experimenter, the plant height if the amount of available light is reduced due to global dimming.

We know that, the global dimming is explained as decreases in the amount of light reaching the surface of the earth .

Aerosols enters the atmosphere and absorb energy and reflect radiation back in to the space , before it reaches the plants.

1. A particle has a mass of 10 kg and a velocity of 5 m/s. What is the momentum of the particle?

Aleksandr [31]

✰ Concept :-

⠀

We know that momentum is the product of mass and velocity. Thus, by the following definition, we get :-

⠀

$\qquad \maltese \: \underline{ \boxed{ \purple{ \sf Momentum = Mass \times Velocity }}} \: \star$

⠀

✰ Given Information :-

⠀

A particle has mass 10 kg
Moving with velocity 5 m/s

⠀

✰ To Find :-

⠀

The momentum of the particle

⠀

✰ Solution :-

⠀

Using the formula from the concept section, we get :-

⠀

$\sf \longrightarrow Momentum =10 \: kg \times 5 \: {m}^{ - 1} ~~~ \\ \\ \\\sf \longrightarrow Momentum = {50~kg \: ms}^{ - 1} \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \sf \longrightarrow \underline{ \boxed{ \frak{ \orange{Momentum = {50 ~kg\: ms}^{ - 1} }}}} \: \star \: \: \: \: \: \: \\ \\$

Thus, the momentum of the particle is 50 kg m/s.

$\underline{ \rule{230pt}{2pt}} \\ \\$

Answer:

Gravity impacts erosion in direct ways like landslides, mudslides and slump. It can also impact erosion in indirect ways, by pulling rain to the Earth and forcing glaciers downhill.

Explanation:

Gravitational erosion describes the movement of soil or rock due to the force of gravity.

Starting from rest, a car travels 18 meters as it accelerates uniformly for 3.0 seconds. What is the magnitude of

omeli [17]

Answer:

$a=4\frac{m}{s^2}$

Explanation:

Hello.

In this case, for this uniformly accelerated motion in which the car starts from rest at 0 m/s and travels 18 m in 3.0 s, we can compute the acceleration by using the following equation:

$x_f=x_0+v_0t+\frac{1}{2}at^2$

Whereas the final distance is 18 m, the initial distance is 0 m, the initial velocity is 0 m/s and the time is 3.0 s, that is why the acceleration turns out:

$a=\frac{2(x_f-v_ot)}{t^2} =\frac{2(18m-0m/s*3.0s)}{(3.0s)^2}\\ \\a=4\frac{m}{s^2}$

Best regards.

It takes 399 newtons to move a 7.2 kg object. What is the acceleration of the object?

Nookie1986 [14]

Answer:

a = 55.42m/s²

Explanation:

F = m*a

F = force(Newtons)

m = mass

a = acceleration

a = F/m

a = 399N/7.2kg

a = 55.42m/s²
