Answer:
Explanation:
We will use the KE equation you wrote here and fill in what we are given:
and isolating the m:
which gives us
m = .50 kg
Answer:a.Dry cell
Explanation: A dry cell is a type of electric battery, commonly used for portable electrical devices like a flashlight
More info is needed. if it is in a controlled circuit I would say yes. but in a non controlled environment I would say no it's a dispersement.
Use the equation potential energy =m*g*h
m-mass,
g-gravitational acceleration,
h-height
Potential energy = 2*10*10
=200
This is the unit of the energy
To produce a maximum emf of 1.0 V, the angular speed should rotate at 35.368 rad/s.
<h3>What is a uniform magnetic field?</h3>
A uniform magnetic field is depicted by parallel straight lines that are distributed uniformly. The flux path is the same as the path of a tiny magnet's north-seeking pole. The flux channels are continuous, producing closed loops.
For a single loop of wire with a radius of 7.5 cm that rotates about a diameter in a uniform magnetic field of 1.6T. We need to determine the angular speed of rotation for it to produce a maximum electromotive force (emf) of 1.0 V.
Given that:
The radius = 7.5 cm, to convert it to meters, we will divide it by 100.
= (7.5/100) m
= 0.075 m
The area A of the wire is computed by using the formula:
A = πr²
A = π(0.075)²
A = 0.01767 m²
Imagine a coil with N turns with area A rotating at a constant angular velocity (q) inside a flux density of a (B) of a magnetic field, with its axis parallel to the field.
The maximum e.m.f can be computed by using the formula:
Where;
- Magnetic field (B) = 1.6 T
Making the angular speed (ω) the subject of the formula, we have:
ω = 35.368 rad/s
