Answer:

<em>Fn = 50 N</em>

Explanation:

<u>Net Force</u>

The net force is the sum of all the forces acting on an object.

When all the forces act in a single line, the direction of the forces is given by their signs. Positive signs are assumed to be up and left on both axes.

The box being raised by a force has a weight of W=-125 N. The negative sign indicates the weight points down. The accelerating force goes up and its value is F=175 N. The positive sign indicates this force pushes the box up.

The forces acting on the box are:

The weight W=-125 N

The accelerating force F=175 N

The net force is

Fn = W + F = -125N + 175 N

Fn = 50 N

UNO [17]

Answer:

Hello the options to your question is missing attached below are the missing options

  • Electrical forces are symmetrical, The electric repulsion of the Balloons is equal because electric forces between two objects are always symmetrical
  • The electric forces are equal in this case because both balloons had the same amount of electric charge

Answer :

Electrical forces are symmetrical, The electric repulsion of the Balloons is equal because electric forces between two objects are always symmetrical

Explanation:

The Balloons have the same amount of force exerted on them, because Electrical forces are symmetrical, The electric repulsion of the Balloons is equal because electric forces between two objects are always symmetrical, therefore the two Balloons are deflected to the same angle

When you drive through deep water, you should dry out your brakes by _____________. pumping your brakes and driving in low gear
Mandarinka [93]

Answer:

By Applying pressure to the brakes

Explanation:

Driving cars through deep water that is more than 10cm can make the cars to float. Most modern cars are usually water- tight so they can start to float through water that is about 30cm deep, fast moving water is very powerful so one needs to be very careful when driving.

If the brakes are wet test them by pressing or tapping on them gently.

You can as well dry brakes by driving in low gear and applying pressure to the brakes.
