Answer:
V = 6.23 cm³
Explanation:
given,
Length of the cylinder, h = 5 cm
Diameter of the cylinder, d = 1.26 cm
r = 0.63 cm
Volume of the cylinder = ?
We know,
V = 6.23 cm³
Volume of the cylinder is equal to V = 6.23 cm³
Answer:
calculate the slope of the line and the slope is equal to the resistance of the circuit m=R
Explanation:
One method for measuring the resistence is to use ohm's law
V = R I
y = mx +b
b=0
m = R
Where we measure various values of voltage and current, with these values we can make a graph of V vs I where we calculate the slope of the line and the slope is equal to the resistance of the circuit

6. An insulator is a material that limits the flow of electricity or heat
7. Light energy is the form electromagnetic energy which the eye can sense
8. An electric current flows an electric circuit which consist of a source of electricity and an path through which the electric current can easily flow.
Answer:
Charge,
Explanation:
A moving particle encounters an external electric field that decreases its kinetic energy from 9650 eV to 8900 eV as the particle moves from position A to position B The electric potential at A is 56.0 V and that at B is 19.0 V. We need to find the charge of the particle.
It can be calculated using conservation of energy as :
q = -20.27 e
Hence, this is the required solution.
