Answer:
Number of turns of wire(N) = 3,036 turns (Approx)
Explanation:
Given:
Diameter = 13 Cm
emf = 5.6 v
Note:
The given question is incomplete, unknown information is as follow.
Magnetic field increases = 0.25 T in 1.8 (Second)
Find:
Number of turns of wire(N)
Computation:
radius (r) = 13 / 2 = 6.5 cm = 0.065 m
Area = πr²
Area = (22/7)(0.065)(0.065)
Area = 0.013278 m²
So,
emf = (N)(A)(dB / dt)
5.6 = (N)(0.013278)(0.25 / 1.8)
5.6 = (N)(0.013278)(0.1389)
N = 3,036.35899
Number of turns of wire(N) = 3,036 turns (Approx)
The magnetic field is holding onto the nail that’s all I got
You convert kinetic energy into thermal energy when you rub two sticks together because of friction. Friction<span> is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Hope this answers the question.</span>
Answer:
1 hour = 3,600 seconds
1 km = 1,000 meters
75 km/hour = (75,000/3,600) m/s = 20-5/6 m/s
The average speed of the bus while it slows down is
(1/2)(20-5/6 + 0) = 10-5/12 m/s .
Traveling at an average of 10-5/12 m/s for 21 seconds,
the bus covers
(10-5/12) x (21) = 218.75 meters .

Answer:
Total number of atoms
Explanation:
According to the Law of Conservation of Mass, <em>mass cannot be created nor destroyed</em>, so to balance a chemical equation, you need to have the <em>same</em> total number of atoms on both sides.
