Marisa does 3.2J of work to lower the window shade in

Physics

Pani-rosa [81]3 years ago
5 0

Work is considered as the Force performed on a body to move it a certain distance, that is

W = Fd

Here

W = Work

F = Force

d = Distance

In this case we have the values of work and distance, therefore clearing for the Force we would have to

F = \frac{W}{d}

Replacing,

F = \frac{3.2J}{8m}

F = 0.4N

Therefore the force that Marissa must exert on the windows shade is 0.4N

andrew11 [14]

Answer:

a shiny smooth leaf

Explanation:

A shiny smooth leaf will cause specular reflection. Other choices will cause diffused reflection from the surface.

A specular reflection is similar to how a mirror or smooth surface reflects. The incident light is given off as a single ordered reflection from the surface of a body.

For this to occur, the surface incident must be smooth and without rough patterns on it.

A path way with rough rocks, small patch of soil and rough logs will give off diffused reflection

Why 2 objects don't attract each other with gravitational force? Explain with newton's law of universal gravitation. PLS NO SEAR
Tema [17]

Answer:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
