Answer:
Explanation:
Total resistance in the circuit
= EMF / current in the circuit
= 12 / .969
= 12.383 ohm
This resistance consists of 5 identical resistances in series
resistance of each resistor
= 12.383 / 5
= 2.476 ohm .
potential difference on each
= current x resistance of each
= .969 x 2.476
= 2.399 V
= 2.4 V
A positive charge and a negative charge held a certain distance apart are released. as they move, the force on each particle increases
The most common charge carriers are the positively charged proton and the negatively charged electron. The movement of any of these charged particles constitutes an electric current
<h3>What is a Charge ?</h3>
When there are more or fewer protons in an atom than electrons, the substance has an electric charge. Protons have a positive charge, while electrons have a negative charge. If a substance has more protons than electrons, it is positively charged; if it has more electrons, it is negatively charged.
- The SI units for charge are ampere-second or coulomb. When one ampere of electric current goes through the conductor for one second, one coulomb of charge passes through it. Charge is denoted by the formula Q = I t.

In the given problem, we say various information's that are going to help us reach the ultimate answer to the question. Let us first write the information's that have been presented in front of us.
Mass of the car = 2000 kg
Velocity of the car = 25 m/s^2
Radius of the circle = 80 m
Now we already know the equation for calculating the centripetal force and that is
Centripetal Force = [mass * (velocity)^2]/Radius
= [2000 * (25)^2]/80
= (2000 * 625)/80
= 1250000/80
= 15625
So the centripetal force on the car is 15625 Newtons
Answer:
2 amps
Explanation:
Given data
Power = 460W
voltage= 230V
Required
The amperage/ current of the fuse
Recall P= IV
I= P/V
I= 460/230
I=2 amps
Hence the current of the fuse is 2 amps
I am pretty sure it’s B (carbon dioxide)
