Answer:
A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. When the horse walks in the forward direction (with the cart attached to it), it exerts a force in the backward direction on the Earth. An equal force in the opposite direction (forward direction) is applied on the horse by the Earth. This force moves the horse and the cart forward. As a result, the cart moves forward.
Answer:
0.888 ohm
Explanation:
We have given that the battery has an emf of 12 volt that E =12 volt
Terminal voltage V =18.4 volt
Current through the battery is =7.20 A
We have top find the internal resistance of the battery
Now according to Kirchhoff's law V=E+IR
So 
So the value of internal resistance of battery is 0.888 ohm
C
Unbalanced causes something to move because the net force is greater than zero
<u>Answer</u>
3 Ohms
<u>Explanation</u>
when the resistors are in series, the resistance in the circuit increases. For example, if two resistors, R1 and R2 are in series, the combined resistance is R1+R2.
When connected in parallel, the total resistance is the reciprocal of (1/R1 + 1/R2)
In this case the resistors are in parallel.
Total resistance = (1/12 + 1/4)⁻¹
= (1/3)⁻¹
= 3 Ohms
