The resultant of the forces is 29 N. Option D
<h3>What is the resultant force?</h3>
The resultant force is the force that acts in a given direction. Now we have two forces as enumerated in the question.
Thus;
Resultant = √(10)^2 + (20)^2 - [2 * 10 * 20 * cos (60 - 30))
Resultant = 29 N
Thus, the resultant of the forces is 29 N.

Answer:
Explanation:
Because when the electric bulb at night switched It emitted the light this light rays forms an image on our retina hence the bulb become visible at night
2 ans
When an electric bulb is switched on, the electricity is allowed to pass in its circuit and is converted into light energy. Thus, a bulb glows when switched on and the eyes perceives the light energy in the visible spectra which is given out by the bulb. Hence, the bulb becomes visible
Answer:
(a)
(b) 29.91 A
(c) 12.24 V
Explanation:
(a) The emf of a battery is the sum of its terminal voltage and lost voltage. The lost voltage is due to the internal resistance. By this, we have for the first condition,
E is the emf, is the terminal voltage and is the lost voltage with I being the current.
Since the same current is drawn in both conditions and the emf does not depend on temperature, we have similar for the second condition
Equating both equations and solving for I, we have
(b) Substitute the values from the question into the expression for I in (a)
(c) Substitute the value of I into any of the equations of E
