Explanation:
The region around a moving charge in which it experience a force is called magnetic field. The force is called magnetic force. The force experienced due to moving charge is given by :
q is the charged particle
v is the speed of particle
B is the magnetic field
The number of magnetic field lines passing through any surface is called magnetic flux. The formula used to find the magnetic flux is given by :
Hence, this is the required solution.

Answer:
False
Explanation:
Please see the attached file
Answer: the answer is false
Explanation:
I just took the test.
A. thumb in the direction of the electromagnetic force.
B. forefinger in the direction of the motion.
C. forefinger in the direction of the lines of force.
D. thumb in the direction of the magnetic flux.
Correct answer choice is:
C. forefinger in the direction of the lines of force.
Explanation:
The direction of the force - and consequently the transfer of the wire - can be defined by applying Fleming’s left-hand rule.
The forefinger tends to the direction of the magnetic field. The middle finger points in the course of the current. The thumb supplies the direction of force or movement working on the conductor. Fleming's Left Hand Rule is applied in electronic engines which are utilized in coolers, appliances, printers, etc.
(1) 1.5 × 10^−15 Hz (3) 1.4 × 10^2 Hz
(2) 4.5 × 10^−7 Hz (4) 6.7 × 10^14 Hz
Wavelength formula is C=λf or λ=C/f or f = C/λ, so Frequency = Velocity divided by wavelength, where C is the velocity, which is the speed of light: 3.00×108 m/sec
λ is the wavelength in meters
f is the frequency in Hertz (cycles per second)
f=3.00×108msec/4.5x10−7m=6.7x1014Hz
27.5 square units
36.0 square units
40.5 square units
45.0 square units
The area of the kite that is inscribed in a square is 40.5 square units.
Given that the side length of the square in which the kite is inscribed is units. The area of a kite is calculated as given below.
Where d1 and d2 are diagonals of the kite that are equivalent to the length of the square. Hence the area can be given as below.
Hence we can conclude that the area of the kite is 40.5 square units.

The velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.
To find the final velocity of the stroller after it has traveled a certain distance while accelerating, one can calculate it using the third equation of motion:
v²-u² = 2as
The third equation of motion is one of the equations used in classical physics to describe the motion of an object with constant acceleration.
Given:
Acceleration, a = 500 m/s²
Distance, s = 6.32 m
The velocity is computed as:
v² - 0² = 2 × 500 × 6.32
v² = 6320
v = 79.5 m/s
Hence, the velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.
