Answer:
3.974 Joule
Explanation:
Diameter of ring = 7.7 cm
a = Distance from the center = d/2 = 3.85 cm = 0.0385 m
Q = Charge = 5 mC
q = Charge to move = 3.4 mC
k = Coulomb constant = 9×10⁹ Nm²/C²
Work done will be equal to Potential energy when mass is at center
∴ Work to move a tiny 3.4 mC charge from very far away to the center of the ring is 3.974 Joule
Double , the force is pushed against the cart added by mass is enough to double the acceleration , and thank u :)
Answer:the force that object be lower
Explanation:bc I got it right
Answer:
P = 6.63 kW
Explanation:
Given that,
Current, I = 260 A
Voltage of the battery, V = 25.5 V
We need to find the power supplied to the starter motor. We know that,
P = VI
Put all the values,
P = 25.5 × 260
P = 6630 W
or
P = 6.63 kW
So, the power supplied to the motor is 6.63 kW.
ANSWER:
C
EXPLANTION:
The earths crust is the toppest layer of Earth, so that elimates option A and B.
FUN FACT:
Earth is Mostly Iron, Oxygen and Silicon
I’m so sorry if this is wrong, but I hoped help.
Have a nice day :3
