264N.s

Explanation:

Given parameters:

Force on door = 88N

Time of action = 3s

Unknown:

Impulse on door = ?

Solution:

Impulse is the force applied on a body in a specific period of time.

Impulse = Force x time

Impulse is related to momentum. Both quantities are the same and are expressed the same way.

Now input the parameters in the equation;

Impulse = 88 x 3 = 264N.s

jonny [76]

We have no way to say what the illustration represents, mainly because
you haven't given us a way to see the illustration.

However, the process that all stars, including our sun, use to continuously
produce energy is nuclear fusion.

1. Determine the magnitude of two equal but opposite charges if they attract one another with a force of 0.7N when at distance o

adell [148]

Answer:

q = 2.65 10⁻⁶ C

Explanation:

For this exercise we use Coulomb's law

F = $k \frac{q_1q_2}{r^2}$

In this case they indicate that the load is of equal magnitude

q₁ = q₂ = q

the force is attractive because the signs of the charges are opposite

F = $k \ \frac{q^2}{r^2}$

q = $\sqrt{\frac{F \ r^2}{k} }$

we calculate

q = $\sqrt{\frac{0.7 \ 0.3^2 }{9 \ 10^9} }$

q = $\sqrt{7 \ 10^{-12} }$ Ra 7 10-12

q = 2.65 10⁻⁶ C

A 20kg object acceleration by a force of 200N with coefficient of kineticfriction is 0.4 what is acceleration of the object?

Schach [20]

Answer:

Given - M = 20 kg

k = 0.4

F = 200 N

To find -  acceleration

Solution - 

F= kMA

200 = 0.4 * 20 * acceleration

200 = 8 * a

a = 8/200

a = 0.04 m s²
