i honestly don't even know but yahoo answers says :

Impulse causes momentum to change, which means:

Impulse = change in momentum, or in equation form:

F∆t = (mv)2 – (mv)1

so p (impulse)= mass times velocity so the mass is 2,000kg and the velocity is 12,000N/5s.

speed is basically velocity so you have to calculate how many newtons per one second, so 12,000/5s-- just divide the numerator and denominator by 5. Also, velocity and speed are measured in N/s.

How is the world do you do this?

Rainbow [258]

You do the net force by subtracting the sides. The direction of the box is moving forward to the right by 10 N.

You place an object 30.0 cm from a concave mirror of 15.0 cm focal length. The object is 1.8 cm tall. Find the image position an

Softa [21]

Answer:30 cm

Explanation:

Given

object distance $u=30\ cm$

focal length of concave mirror $f=15\ cm$

height of object $h_o=1.8\ cm$

Using mirror formula

$\Rightarrow \frac{1}{v}+\frac{1}{u}=\frac{1}{f}$

$\Rightarrow \frac{1}{v}=\frac{1}{15}-\frac{1}{30}$

$\Rightarrow \frac{1}{v}=\frac{2-1}{30}$

$\Rightarrow v=30\ cm$

and magnification is

$\Rightarrow m=\frac{-v}{u}=\frac{h_i}{h_o}$

$\Rightarrow \frac{-30}{30}=\frac{h_i}{1.8}$

$\Rightarrow h_i=-1.8\ cm$

So height of object is same as of object .

Position :image is formed at the spot where object is placed.

Coal is a major fossil fuel which is mined in many countries around the world. Which of these is most likely to happen if coal i

Troyanec [42]

<span>If coal is stacked near mines, the most likley thing that will happen is that rain watter will carry contaminants in coal into durface water. When rain falls on coal, it erodes it just like any other rock. So amounts of coal can be washed out of its holding area and into surface *and* groundwater. Correct answer:D</span>
