is the equation that represents the Joule's law of heating.
<h3>
Explanation:</h3>
Joule's law of heating defines the heat generated by any current flowing conductor is directly proportional to
1. Square of Current (I²),
2. Resistance of the conductor (R)
3. Time for which current is passed (t)
Hence, Heat generated = .....................(1)
By Ohm's Law, the potential difference (V) across a conductor is directly proportional to the current(I) flowing through it. The constant of proportionality is termed as resistance of the conductor (R).
...............................................(2)
From (2), Current (I) can be rewritten as
........................................................(3)
Substituting (3) in (1), we get
Answer:
n = 3
Solution:
Since, the slit used is same and hence slit distance 'x' will also be same.
Also, the wavelengths coincide, will also be same.
Using Bragg's eqn for both the wavelengths:
(1)
(2)
equate eqn (1) and (2):
n = 3
Answer:
the answer is false :)
Explanation:
Science is based on theories and tests, if someone has a theory they will test and if it is correct yippie! and if it isn't they will redo the test over until they get it correct or unless it is unsolvable.
Answer:
Explanation:
We are asked to find the final velocity. We are given the acceleration, time, and initial velocity, so we can use the following kinematics formula.
In this formula, is the final velocity, is the initial velocity, is the acceleration, and is the time.
The bicycle has an initial velocity of 5.0 m *s⁻¹ or m/s, acceleration of 2 m/s², and a time of 5 seconds.
Substitute the values into the formula.
Solve inside the parentheses.
Add.
The units can also be written as:
The bicycle's final velocity is 15 meters per second.
