The spaceship enters a geosynchronous orbit is M = 4π 2 R 3 /GT 2 M = 1.35 × 10²⁸ kg.

A geostationary orbit is a low-inclination prograde orbit around the Earth lasting 23 hours 56 minutes and 4 seconds. A spacecraft in a geostationary orbit appears to move north and south but appears to stay at a fixed longitude on Earth. A geostationary orbit is a geostationary orbit.

A geostationary satellite orbit is an orbit around the Earth that intentionally has an orbital period of one sidereal day equal to the Earth's sidereal rotation period, with the satellite returning to the same position in the sky after each sidereal day. Geostationary means that the satellite orbits with the same angular velocity as the earth.

Photoreceptors, in contrast to most sensory receptor cells, have a hyperpolarization response to stimulation and a depolarization response to inhibition. This indicates that when the cell is not activated, glutamate is constantly released; but, when the cell is triggered, release ceases.

As I previously stated, if a light ray strikes rhodopsin as it enters the eye and strikes a rod, it will really start a phototransduction cascade that causes the rod to fire an action potential. In a cone, the identical procedure takes place.

Cones and rods provide visual signals to bipolar cells, which send them on to ganglion cells. The retina itself is where a significant portion of visual information processing takes place.

The coefficient of friction = 0.34 between the rope and the support.

This type of question can be solved using Capstan's equation,

Capstan's equation is generally used to calculate the friction of the coefficients or the yarns. Represented as-

[tex]T_{1} = T_{0}e^{u}[/tex].

Now according to the term coefficient of friction, we calculate the friction between any two surfaces. It is also referred to as the ratio of the resistive force to the normal force.

The Capstain's equation is given by-

[tex]T_{load} = T_{hold} e^{uo}[/tex]

u is given as μ and o denotes Φ

the load = 7000

hold support is 100N

Φ = 2[tex]\pi[/tex] for the whole rotation

Since the rope is wrapped 2 times = 4[tex]\pi[/tex]

7000 = 100[tex]e^{u4\pi }[/tex]

log on both sides

The time for the crest of a wave having a frequency of 810 hz, a wavelength of 0.40 m, and an amplitude of 4.0 mm to travel to the closest length of wire is 19 ms.

Wavelength is the distance between one wave frequency peak and another peak. Therefore, the wavelength of frequency is the distance that a wave must travel in one period. This wavelength is denoted by the symbol λ (lambda) with units of m (meters).

the equation between wavelength, speed and frequency is:

λ = v/f

We have,

Wavelength = 0.4 m  ⇒ λ

Frequency = 810 hz ⇒ f

Distance = 6.0 m

And, the velocity:

v = λ x f

The picture distance is s'.

The radius of curvature is R.

Now, the distance between an item and the point of curvature equals the radius of curvature.

s = R

Using s = R as a substitute and solving for s'

s' = [tex]((\frac{2}{R} ) - (\frac{1}{s} ))^{-1}[/tex]

s' = [tex]((\frac{2}{R} ) - (\frac{1}{R}))^{-1}[/tex]

The angular speed of the lander at the end of the rotating arm is 4.98 rpm.

It is given to us that -

The radius of the rotating arm = 4.25 m

Mass of the Europa = [tex]4.80 * 10^{22}[/tex] kg

Diameter of the Europa = 3120 km

=> Radius of the Europa = 3120/2 = 1560 km = 1,560,000 m

We have to find out the angular speed (in rpm) at which the rotating arm should spin so that the acceleration of the lander is the same as the acceleration due to gravity at the surface of Europa.

Firstly, we have to find out the acceleration due to gravity of the Europa. We know that the force on the Europa can be given as -

[tex]F = Mg\\= > Mg = \frac{G*m*M}{R^{2} } \\= > g = \frac{G*m}{R^{2}}\\= > g = \frac{(6.67 * 10^{-11} )*(4.80*10^{22} )}{1560000^{2} } \\= > g = 1.19 m/s^{2}[/tex] ----- (1)

It is given to us that -

Acceleration of the lander = Acceleration due to gravity at the Europa

[tex]= > a_{l} = g\\= > a_{l} = 1.19 m/s^{2}[/tex] ----- (2)    [From equation (1)]

Now, to calculate the angular speed of the lander, we can use the formula as -

[tex]= > a_{l} = w^{2} r\\= > w^{2} = \frac{a_{l} }{r} \\[/tex] ----- (3)

where,

[tex]a_{l}[/tex] = Acceleration of the lander

[tex]w[/tex] = angular speed of the lander

r = radius of the rotating arm

Substituting the values of [tex]a_{l}[/tex] from equation (2) and r in equation (3), we have -

[tex]w^{2} = \frac{a_{l} }{r}\\= > w^{2} = \frac{1.19 }{4.25}\\= > w^{2} = 0.28\\= > w = 0.529 rad/s[/tex]

In order to convert the angular speed in rpm, we have to use -

[tex]w = 0.529 rad/s\\= > w = 0.529 * \frac{1 rev * 60 s}{2\pi rad*1 min}\\ = > w = 4.98 rpm[/tex]

Due to their mutual free fall, the pendulum as well as the position to which it is linked will no longer oscillate.

Pendulum a body that is hanged from a fixed location and moves back and forth as a result of gravity. Pendulums are employed to control clock movement because the period the amount of time between each full oscillation is constant.

We will utilize the concept of the duration in a basic pendulum to tackle this issue, which cautions that it depends on the length and gravity of the pendulum:

T = 2π√(L/g)

Here,

L = Length

g = Acceleration due to gravity

T = √(L/g)

Since 2π is a constant, we can deduce that its proportionality towards the square root of the its lengths over its gravity is 2.

g→ 0 ⇒ T→∞

The object is in continuous free fall, or in a situation where gravity is typically zero.

The period's value will eventually approach infinity. As a result of the pendulum's attachment point also being in free fall, it means that the pendulum would no longer oscillate.

where q is the charge of the particle, v is the velocity of the particle and B is the magnitude of the magnetic field.

When the magnitude of the magnetic field is decreased at a rate of -0.16 t/s, the force on the particle will be in the opposite direction of the decreasing magnetic field. This is because the magnitude of the magnetic field will be decreasing over time, so the force on the particle will be in the opposite direction of the decreasing magnetic field.
