Answer:
2.86×10⁻¹⁸ seconds
Explanation:
Applying,
P = VI................ Equation 1
Where P = Power, V = Voltage, I = Current.
make I the subject of the equation
I = P/V................ Equation 2
From the question,
Given: P = 0.414 W, V = 1.50 V
Substitute into equation 2
I = 0.414/1.50
I = 0.276 A
Also,
Q = It............... Equation 3
Where Q = amount of charge, t = time
make t the subject of the equation
t = Q/I.................. Equation 4
From the question,
4.931020 electrons has a charge of (4.931020×1.6020×10⁻¹⁹) coulombs
Q = 7.899×10⁻¹⁹ C
Substitute these value into equation 4
t = 7.899×10⁻¹⁹/0.276
t = 2.86×10⁻¹⁸ seconds
As the resistance of a circuit increases, the current will decreases.
<h3>What is ohm’s law?</h3>
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
When all physical parameters and temperature are constant,
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically by Ohm's law as;
V=IR
If the voltage is constant, the resistance of the circuit will be inversely proportional to the current.
Hence,as the resistance of a circuit increases, the current will decreases.

Answer:
When all of the domains are aligned, the material is said to be magnetically saturated. When a material is magnetically saturated, no additional amount of external magnetization force will cause an increase in its internal level of magnetization.
Answer:
KE= (1/2)mv^2
given m, the remaining components of the equation are=
1/2v^2?
Explanation:
KE= (1/2)mv^2
plug in...
=(1/2)(27 kg)(3 m/s)^2= 121.5
KE= 121.5 J
Explanation:
the impulse and momentum change on each object are equal in magnitude and opposite in directions. Thus the total momentum is reserved
