The velocity is 6.52 m/s, and the velocity in component vector form is vcos.

"The pace at which an item changes its location" is described by a vector number known as velocity. Consider someone walking swiftly, one step ahead, one step back, and beginning each stride in the same place. Velocity is measured as a vector quantity. As a result, velocity is aware of direction. When calculating an object's velocity, the direction must be considered. A speed of 55 miles per hour does not provide enough information. To accurately represent the velocity of an object, the direction must be taken into account. Simply simply, the direction of the velocity vector describes the object's motion.

The maximum height reached by the ball thrown upwards with kinetic and potential energies specified is nearly 20 m.

Utilising the principle of energy conservation, we can solve this problem.

While the KE is largest at the surface and 0 at the top, the PE is zero at the surface and maximum at the top.

From the above data,

PE = mgh = 50 J ----(1)

m g* 10 = 50

m* g = 50/10

m* g = 5

The total energy at that point = PE + KE = 50 + 50 = 100 J

The PE will therefore be 100 J at the highest point.

m g H = 100 J , H is the needed height

Using the above-mentioned value of m* g, we have

H = 100/5

H = 20 m

So, the maximum height reached by the ball is 20 m.

The work that has been done by air resistance during this time is 55800 k m²/s².

To determine the work done by air resistance during the skydiver's fall, we can use the equation:

W = F × d

where W is the work, F is the force of air resistance, and d is the distance traveled.

The force of air resistance on the skydiver is given by the equation:

F = k × v²

where k is the drag coefficient, which is a measure of the resistance of the air to the movement of the object, and v is the velocity of the skydiver.

To determine the work done by air resistance, we need to determine the distance traveled by the skydiver and the force of air resistance at each point in her fall. The skydiver falls from an altitude of 1500 m to an altitude of 425 m, a distance of 1075 m.

At an altitude of 1500 m, the skydiver is falling at a terminal velocity of 52 m/s. Plugging these values into the equation for the force of air resistance gives us:

F = k × v² = k × (52 m/s)²

To determine the work done by air resistance at this point in the skydiver's fall, we can plug the value of F and the distance traveled into the equation for work:

W = F × d = (k × (52 m/s)²) × 1075 m = 55800 k m²/s²

The work done by air resistance at this point in the skydiver's fall is 55800 k m²/s².

At an altitude of 425 m, the skydiver is falling at a terminal velocity of 52 m/s. Plugging these values into the equation for the force of air resistance gives us:

F = k × v² = k × (52 m/s)²

To determine the work done by air resistance at this point in the skydiver's fall, we can plug the value of F and the distance traveled into the equation for work:

W = F × d = (k × (52 m/s)²) × 1075 m = 55800 k m²/s²

The work done by air resistance at this point in the skydiver's fall is 55800 k m²/s².

To determine the total work done by air resistance during the skydiver's fall, we can add the work done at each point in the fall:

W_total = W_1500m + W_425m = 55800 k m²/s² + 55800 k m²/s² = 111600 k m²/s²

The total work done by air resistance during the skydiver's fall is 111600 k m²/s².

Note that this calculation assumes that the drag coefficient k is constant throughout the skydiver's fall. If the drag coefficient changes during the fall (for example, if the skydiver deploys a parachute), additional calculations will be needed to determine the total work done by air resistance.

[tex]B_{f}[/tex]T(1 * [tex]10^{-6}[/tex] [tex]m^{2}[/tex]) = [tex]B_{f}[/tex]* [tex]10^{-6}[/tex] T[tex]m^{2}[/tex] front surface

The net flux through all of the box's surfaces should be zero.

(6T +6T-4T-2T+BfT)([tex]10^{-6}[/tex][tex]m^{2}[/tex]) = 0

When we divide [tex]10^{-6}[/tex][tex]m^{2}[/tex] on both sides, we get:

12T-8T+[tex]B_{f}[/tex]=0

4T+[tex]B_{f}[/tex] = 0

[tex]B_{f}[/tex]= - 4T

On the front surface, the magnetic field strength is [tex]B_{f}[/tex] = - 4T.

Because it is negative, it indicates that the magnetic field is entering the front surface.

If an object doubles its luminosity in 10 hours, emitting source of light can be about 10 light hours across.

Luminosity, L, is a measure of the total amount of energy radiated by a star or other celestial object per second. This is therefore the power output of a star. A star's power output across all wavelengths is called its bolometric luminosity. A star's luminosity can be determined from two stellar characteristics: size and effective temperature. The difference between luminosity and apparent brightness depends on distance.

Since, the luminosity of the object doubles in 10 hours, emitting source of light can be about 10 light hours across.

In a photoelectric effect experiment at a frequency above the cut off frequency the number of electrons ejected is proportional to the number of photons that hit the sample per second.

The photoelectric current is measured in relation to the intensity of the incident radiation at a specific frequency and potential between the metal plate and collector. It demonstrates that incident radiation intensity and photoelectric current are inversely correlated. The photoelectric current shows how many photoelectrons are released each second.

The idea of light as a wave cannot be used to explain the photoelectric effect. However, the particle nature of light, which can be visualized as a stream of electromagnetic energy-containing particles, can provide an explanation for this phenomenon. These particles of light are called as photons.
