The force acting on the cart is 1.43 N.
<h3>What is force?</h3>
Force can be defined as the product of mass and acceleration.
To calculate the force acting on the cart, we use the formula below.
Formula:
- F = m(v-u)/t................. Equation 1
Where:
- F = Force acting on the cart
- m = mass of the cart
- v = Final velocity
- u = initial velocity
- t = time
From the question,
Given:
- m = 500 g = 0.5 kg
- v = 30 m/s
- u = 10 m/s
- t = 7 seconds
Substitute these values into equation 1
- F = 0.5(30-10)/7
- F = 10/7
- F = 1.43 N.
Hence, the force acting on the cart is 1.43 N.

Answer:
Motors convert electrical energy into mechanical energy
Explanation:
A motor uses electrical energy to create mechanical energy by creating magnetic fields causing the motor to spin. A generator is the opposite and converts mechanical into electrical by spinning a motor in a magnetic field.

The charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.
<h3>What are electrons?</h3>
The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
The charge on electron is equal to e = -1.6 x 10⁻¹⁹C
The charge of an anti- charm quark is +23 times the magnitude of charge on electron.
So, charge on anti- charm quark is
q = +1/3 x ( 1.6 x 10⁻¹⁹C)
q = +5.33 ×10⁻²⁰ C
Thus, the charge of an anti-charm quark is approximately equal to +5.33 ×10⁻²⁰ C.
