The force that a body gets when it is far from the earth can be described as the power of pulling toward this center of the earth. The due to gravity increases with increasing distance. Its mathematical formula is.

m : mass

g : gravity

h : height

Calculation

If we want to know the potential energy at the starting point (point A) then we only have to use the equation Ep:

Ep = mgh

m =3kg

g = 10m/s²

h = 3m

Ep = 3kg*10m/s²*3m

Ep = 90J

Now if we want to know the kinetic energy at point B, we must make an

energy balance

Ea = Eb

90J = Ec + Epb

90J = Ec + 3kg*10m/s²*1m

Ec = 60J

The farthest point of the trajectory must not exceed a height of 3m, and this is point G.

Part (a) The period of oscillation is given by the formula: T = 2π  × [tex]\sqrt{(m/k)}[/tex]

Since the mass is increased by a factor of four, the period will change as follows: T' = 2π  × [tex]\sqrt{(4m/k)}[/tex] = 2π × 2 × [tex]\sqrt{(m/k)}[/tex] = 4π  × [tex]\sqrt{(m/k)}[/tex] = 2 × T

The period doubles. So, the answer is 2) The period doubles.

Part (b) The total mechanical energy of the system is given by the formula: E = 1/2 × kA² + 1/2 × mv²

Since amplitude A and spring constant k are constant, the only change in energy is due to the change in mass. If the mass is increased by a factor of four, the total mechanical energy will change as follows:

E' = 1/2 × kA² + 1/2 × 4mv² = kA² + 2mv² = 2(1/2 × kA² + 1/2 × mv²) = 2E

The energy doubles. So, the answer is 2) The energy doubles.

Part (b) The mass is increased by a factor of four, keeping A and k constant. The total mechanical energy will increase by a factor of four. So, the answer is 1) The energy increases by a factor of four.

Part (c) The mass is increased by a factor of four, keeping A and k constant. The maximum speed will decrease by a factor of four. So, the answer is 4) The maximum speed decreases by a factor of four.

The magnitude of the electric field is 50 N/C and the direction is to the right. The electric field is there whether or not a charged object is present in that area.

An electric field, or alteration of a space and field in the vicinity of a charged item, is produced. The odd change in the environment would be felt by other charges within this sector.

A charged particle produces electric force in the area around it, which is known as the electric field. Electric fields interact when charged particles were close enough to one another to exert force on one another. Incompatiblely charged particles are drawn to one another. Like-charged particles repel one another.

The magnitude and direction of the electric field can be found using the formula:

F = qE

where F is the force exerted on the charge, q is the charge, and E is the electric field.

Given that the force exerted on the charge is 4 N, and the charge is 0.08 C, we can find the electric field by rearranging the equation to:

E = F/q

The magnitude of electric field is:

E = 4 N / 0.08 C = 50 N/C

To determine the direction of the electric field we can use the given information that the force exerted on the charge is 4 N to the right. The force on a positive charge due to an electric field is in the direction of the field, so the electric field is in the direction of the force, which is to the right.

The RMS value of the line voltage will be 340.7 V, if the voltage of 60Hz power line is 480V.

The RMS value of a sinusoidal voltage is a measure of the effective or heating value of the voltage, and is equal to the value of a DC voltage that would produce the same amount of heat in a resistive load. RMS is calculated by taking the square root of the mean of the square of the instantaneous voltage over one period of the wave.

For a sinusoidal voltage with a peak value of 480V and a frequency of 60Hz, the RMS value can be calculated using the formula:

RMS = (Peak Value) / √2

Plugging in the given values, we get:

RMS = 480V / √2 = 340.7V

So the RMS value of the line voltage is 340.7V. It's important to note that, the RMS value is used to calculate the power in AC circuits, as it gives the effective power for the same heating effect as DC circuits.

In this case, the force acting on the shuttle is the upward thrust generated by the engines, which is 1.3 x 108 N.

The mass of the shuttle is 2.0 x 106 kg.

Therefore, the acceleration of the shuttle can be calculated as:
