His mass is 50 kg . . . on the Moon, on the Earth, in the capsule rocketing between them, and on Halley's comet if he ever goes there.
The time required (in s) for the magnetic field to decrease to zero from its maximum value is 1.2 x 10⁻⁶ s.
<h3>
Faraday's law of electromagnetic induction</h3>
Faraday's first law of electromagnetic induction states, “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced.
emf = NdФ/dt
emf = NBA/t
where;
- N is number of turns of the coil
- A is area of the coil
- B is magnetic field
- t is time
The time required (in s) for the magnetic field to decrease to zero from its maximum value is calculated as follows;
t = NBA/emf
t = (16 x 1.1 x 10⁻³ x 3.75 x 10⁻⁴) / (5.5)
t = 1.2 x 10⁻⁶ s
Thus, the time required (in s) for the magnetic field to decrease to zero from its maximum value is 1.2 x 10⁻⁶ s.

Answer:
P=627.47W
Explanation:
To solve this problem we have to take into account, that the work done by the winch is
the force, at least must equal the gravitational force
with force the tension in the cable makes the winch go up.
The work done is
To calculate the power we need to know what is the time t. But first we have to compute the acceleration
The acceleration will be
and the time t
The power will be
HOPE THIS HELPS!!
Answer:
Explanation:
Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. Metalloids have mixed properties which are difficult to characterize. Conductivity: Semi-conductive.
Neither do.beacuse diffusion occurs due the random movement a substance's particals move from a higher concentration to a lower concentration down the concentration gradient.On the other hand osmosis is the movement of water molecules from a high water potential to a low water potential through a partially permeable membrane.thus no energy is required for them to do so.Active transport is a process that requires energy.
