Answer:
I = 12*B (the information about B does not appear in the statement)
Explanation:
The motion of the segment of the circuit, in a constant magnetic field makes that opposite charges inside the segment separate of each other. This generate a induced potential difference at the ends of the segment that is given by the following formula:
(1)
v: speed of the segment = 2.0m/s
B: magnitude of the magnetic field
(2)
The induced current calculated by replacing the result of (2) in the following formula:
(3)
Then, you only have to replace the value of the magnitude of the magnetic field B in (3) to calculate the current.
Cosmic rays are high-energy radiation which do not have a visible color, but if you mean the paint type it is a grayish color.
Answer:
Explanation:
According to the law of the conservation of energy, the gravitational potential energy of the physical system will be converted into rotational kinetic energy. So, we have:
Is the moment of inertia of the system, that is the sum of the moments of inertia of the disk and the small object.
The speed of the train after an additional 5 s has elapsed is 9.45 m/s
<h3>What is acceleration? </h3>
This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
- a is the acceleration
- v is the final velocity
- u is the initial velocity
- t is the time
<h3>How to determine the acceleration in 5.4 s</h3>
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 4.9 m/s
- Time (t) = 5.4 s
- Acceleration (a) =?
a = (v – u) / t
a = (4.9 – 0) / 5.4
a = 4.9 / 5.4
a = 0.91 m/s²
<h3>How to determine the final velocity after 5 s</h3>
- Initial velocity (u) = 4.9 m/s
- Acceleration (a) = 0.91 m/s²
- Time (t) = 5 s
- Final velocity (v) = ?
a = (v – u) / t
0.91 = (v – 4.9) / 5
Cross multiply
v – 4.9 = 0.91 × 5
v – 4.9 = 4.55
Collect like terms
v = 4.55 + 4.9
v = 9.45 m/s
