Using two spring scales, students pull on opposite sides of a dynamic cart at rest. 7 newtons of force is pulling left and 5 newtons force is pulling right. describe the motion of the cart?

The cart will accelerate to the left

Explanation:

The cart is initially at rest. In order to understand its motion, we should consider the net force acting on the cart. We have two forces acting on it:

- A force of 7 N to the left

- A force of 5 N to the right

Therefore, the net force is

in the direction of the stronger force (so, to the left).

According to Newton's second law:

a net force different from zero produces an acceleration of the object, in the same direction as the net force. Therefore, the cart will accelerate to the left.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
