Answer:
Explanation:
The electrostatic potential energy for pair of charge is given by
U=1/4π∈₀×(q₁q₂/r)
Hence for a system of three charges the electrostatic potential energy can be found by adding up the potential energy for all possible pairs or charges.For three equal charges on the corners of an equilateral triangle,the electrostatic potential energy is given by:
U=1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)
U=3×1/4π∈₀×(q²/r)
Substitute given values
So
Answer:
False
Explanation:
The current flowing through a circuit can be computed by using Ohm's law:
where
V is the voltage of the battery
Req is the total resistance of the circuit
Let's now compare the two situations. Let's call R the resistance of each resistor (since they are identical, they have same resistance, R)
- Series configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(1)
- Parallel configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(2)
By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration:
therefore, the correct answer is false.
Answer:
a
Explanation:
When people jump from greater height, energy gets absorbed into the muscles as potential. And when the person flexes her legs on landing energy is trans formed not only into elastic energy in the bones, but also into elastic energy in other tissues and into thermal energy.
air resistance is very small hence, negligible. So, the statement a is correct and rest are wrong.
The gravitational force does change believe it or not, but the explaination for this is because the earths orbit is an oval (or a not circle) the closer it nears its self to the sun.
