Answer:
qn is wrong pe= mgh but there is no height
Answer:
Explanation:
500 W = 500 J/s
500 J/s(2 min(60 s/min) = 60000 J
Answer:
1) 10 Ω of resistance produced a current of 2.5 Ampere.
2) 100 Ω of resistance produced a current of 0.25 Ampere.
Explanation:
Ohm's law is defined as the law which gives us the relationship between voltage and current.
The equation used to represent this law is:
where,
V = voltage of the circuit. The unit for this is Volts.
I = current of the circuit. The unit for this is Amperes
R = resistance of the circuit. The unit for this is Ohms.
1) 10 Ω of resistance produced a current of:
V = 25 Volts
2) 100 Ω of resistance produced a current of:
V = 25 Volts
Answer:
88 m/s
Explanation:
To solve the problem, we can use the following SUVAT equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
d is the distance covered
For the car in this problem, we have
d = 484 m is the stopping distance
v = 0 is the final velocity
is the acceleration
Solving for u, we find the initial velocity:
Incomplete question. However, I provided a brief about Kinetic energy generation.
<u>Explanation:</u>
Interestingly, Kinetic energy in simple terms refers to the energy possessed by a body in motion.
It is often calculated using the formula E =
A good example of creating even more kinetic energy is a hand crank toy car that moves after you wind it a little, when the car moves it is generating another measure of K.E.
