Answer:

Explanation:

The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.

I = 0.33 A

= 330 mA

Capacity, P = I × t

= 2050/330

= 6.21 hours

There is a 3-kg toy cart moving at 4 m/s. Calculate the kinetic<br> energy of the cart.
m_a_m_a [10]

The kinetic energy of the cart is 24 J.

<u>Explanation:</u>

The acceleration of a given mass from rest to the velocity is known as kinetic energy. It gains energy from acceleration and remains in this state until the speed of the object changes.  

The kinetic energy is the given by,

                           K.E = 1/2 mv^2

Given the mass m = 3 kg,        v = 4 m / s.

                            K.E = 1/2 \times 3 \times (4)^2          

                          K.E  = 24 J.
