8. If a circuit has a current of 25.4 amps with 12.6
1 answer:
The resistance of the circuit is
Explanation:
We can solve the problem by applying Ohm's law, which gives us the relationship between current, potential difference and resistance in a circuit:
where
V is the potential difference
R is the resistance
I is the current
For the circuit in this problem,
V = 12.6 V
I = 25.4 A
Re-arranging the equation, we can solve for the resistance:

Explanation:
Given
mass of bus along with travelers travelling in North direction is
speed of bus towards North
mass of bus travelling in South direction is
speed of bus
mass of each Passenger in south moving bus
Momentum of North moving bus
Momentum with south moving bus
For total momentum to be towards south
should be greater than 0
thus for least value of n
337493603.8m/s²
Explanation:
Radius of the earth = 6.38 x 10¹⁶m
time = 24hr (86400s)
Unknown:
Centripetal acceleration = ?
Solution:
The centripetal acceleration is directed inward to keep the body from falling off the surface of the earth.
centripetal acceleration =
where v is the velocity and r is the radius
also;
v = wr
where w is the angular velocity
substituting in the equation for centripetal acceleration gives;
a = w²r
also w =
therefore;
a =
a =
a = 337493603.8m/s²
