Dave and Alex push on opposite ends of a car that has a mass of 875 kg. Dave pushes the car to the right with a force of 250 N,
White raven [17]

The net force acting on the car is 65 N to the left

The net force acting on an object is simply defined as the resultant force acting on the object.

From the question given, we obtained the following data:

  • Force applied to the right (Fᵣ) = 250 N
  • Force applied to the left (Fₗ) = 315 N
  • Net force (Fₙ) =?

The net force acting on the car can be obtained as follow:

Fₙ = Fₗ – Fᵣ

Fₙ = 315 – 250

<h3>Fₙ = 65 N to the left </h3>

Therefore, the net force acting on the car is 65 N to the left

A parallel-plate capacitor consists of a set of two parallel plates of area A separated by a distance d. This capacitor is conne
icang [17]

Answer:

1) the capacitance of the capacitor increases. This is due to the induction of opposite charges on the two surfaces of the dielectric by the plate, this increased the charge in the field, from C =Q/v, it is seen that capacitance C will increase with increase in Q since v is constant.

2) the electric field intensity will also increase with increase in electric charges provided plate separation d remains constant.

By what factor should the length of a simple pendulum be changed in order to triple the period of vibration?
kenny6666 [7]

Answer:

increased by 9 times

Explanation:

As the period of a simple pendulum is defined as the following formula

T = 2\pi\sqrt{\frac{L}{g}}

where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that \sqrt{9} = 3
