The current passing through a circuit consisting of a battery of 12 V and resistor of 2 ohms is 6 Ampere
.
Explanation:
- Assume the wires are ideal with zero resistance.
- The current passing through the circuit will be
I = V/R = 12/2 = 6.000 A.
Answer:
16.5 kwh and 59400 kJ.
Explanation:
kWh is a measure of energy that is equivalent to the power in kw times the number of hours the device worked.
In this case, it would be equal to:

1 kw also means 1kj of energy spent per second. With this, we calculate the amount of energy in kJ spent by the resistance:

45km/h * 0.5h= 22.5km
The car can travel 22.5km in 0.5 hours
Calculated weight (by experimentally) of Earth is 5.972 × 10²⁴ N
Hope this helps!
#1
Work done is given by

here we know that
F = 157 N
d = 14.5

now from the above formula

#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg




#3
By momentum conservation we know that




#4
by momentum conservation we know that

let direction of velocity of Jay Z car motion is positive direction
now we will say



Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say

here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
