<span>Back in the day, one measured a printer's speed in CPM, which stands for characters per minute. Most of the modern printers that exist today, including the inkjet printer measure their speed in PPM, which is also known as pages per minute.</span>

If a small motor does 520 J of work to move a toy car 260 m, what force does the engine exert on the car?

ohaa [14]

Answer:

<h2>2 N</h2>

Explanation:

The force engine exert on the car can be found by using the formula

$f = \frac{w}{d} \\$

w is the workdone

d is the distance

From the question we have

$f = \frac{520}{260} = 2 \\$

We have the final answer as

<h3>2 N</h3>

Hope this helps you

Which has more momentum, a 2.0 kg dog at 41 m/s or a 75 kg pony at 1.0 m/s?

Nesterboy [21]

Answer:

The dog has more momentum than the pony.

Explanation:

To solve this problem, we must remember the formula for calculating momentum, which is given below:

momentum = p = m*v

where m represents the mass of the object and v represents the velocity of the object

Using this knowledge, let's calculate the momentum for the dog and the pony.

Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s

Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s

Since 82 > 75, we can conclude that the dog has more momentum.

Hope this helps!

Calculate the force of gravity on the 0.50-kg mass if it were 6.4×106 m above earth's surface (that is, if it were two earth rad

Sunny_sXe [5.5K]

Radius of Earth is given as

$R = 6.4 * 10^6 m$

now here the height from the surface of earth is same as that of radius

$h = 6.4 * 10^6 m$

now here the acceleration due to gravity at this height is given as

$g' = \frac{GM}{(R+h)^2}$

$g' = \frac{GM}{4R^2}$

$g' = \frac{g}{4}$

now the force of gravity on the given object will be

$F = mg'$

$F = m*\frac{g}{4}$

$F = 0.5 * \frac{9.8}{4}$

$F = 1.225 N$

<em>so the force of gravity on it is 1.225 N</em>
