Explanation:
It is stated that,
Area of square coil, 
Length of one side of the square, L = 0.02 m
Number of coils, N = 10000
Consistent magnetic field, B = 1.5 T
Velocity, v = 100 m/s
An electromotive force is produced in the coil calculated as:
E = 30000 V
Breakdown voltage of air, 
Let d be the distance between the ends of the coil wires that can still produce a spark. Therefore,
Electric field, 
d = 0.075 m
Thus, this forms the final answer.
B. The charge on A is -q; B has no charge. Given that a positive charge is situated at the center of an uncharged metallic sphere which is insulated and disconnected from the ground, a negative charge (-q) will appear on the inner surface A of the sphere. Should the exterior surface B be grounded, it will become neutral, resulting in no charge remaining on surface B.
Greetings!
Using the formula F = Bqv sin theta, we define F as Force, B as magnetic flux density, q as charge, v as velocity, and theta as the angle created by the moving electrons in relation to the magnetic field.
^^^You can compute the force using that equation^^^
In conclusion, your result would MOST LIKELY be "B".

Answer:
h = 12.8 cm
Explanation:
The initial parameters are as follows:
distance = 6.4 cm
- when the object descends, its weight matches the spring's force
weight = spring force
mg = ky... equation 1
- potential energy stored in a stretched spring = work done by the spring
mgh = 0.5 x k x h^{2}....equation 2
- Substituting from equation 1 into equation 2
kyh = 0.5 x k x h^{2}
y = 0.5 x h
2y = h
- where y is 6.4, yielding the maximum elongation as
h = 2 x 6.4 = 12.8 cm
Answer:
The temperature of the cooler object was nearly at room temperature. As a result, the system underwent minimal change
Explanation:
In a closed system with two objects at varying temperatures, heat energy typically flows from the hotter object to the cooler one. This transfer is more pronounced when there is a significant temperature disparity between the objects. Conversely, if the temperature difference is minor or negligible, the resulting change will be minimal.
