The rocket engine works on the basic principle proposed by Newton which is Newton’s Third Law.
Answer:f^n=m(a+g)
Explanation:khan academy said
We can calculate the work done by the machine by the mathematical formula,
P = W/t
where, P = Power
W = work done
t = time
Answer:
8N
Explanation:
Applied force - Frictional force = net force
Answer:
The resistance of the bulb is 1000 ohms.
Explanation:
What is the resistance of a bulb that is connected to a 20 v source through which a current of 20 mA passes
We have,
Voltage of the bulb is 20 V and the current passes is 20 mA.
It is required to find the resistance of the bulb. The relation between resistance, current and voltage is given by using Ohm's law as :
V = IR
R is resistance
So, the resistance of the bulb is 1000 ohms.
