A 11.0 kg satellite has a circular orbit with a period of 1.80 h and a radius of 7.50 × 106 m around a planet of unknown mass. I
Anuta_ua [19.1K]

Answer:

Explanation:

Expression for times period of a satellite can be given as follows

Time period T = 1.8 x 60 x 60

= 6480

T² = \frac{4\times \pi^2\times r^3}{GM} where T is time period , r is radius of orbit , G is gravitational constant and M is mass of the satellite.

6480² = 4 x 3.14² x 7.5³ x 10¹⁸ / GM

GM = 4 x 3.14² x 7.5³ x 10¹⁸ / 6480²

= 3.96 X 10¹⁴

Expression for acceleration due to gravity

g = GM / R² where R is radius of satellite

20 = 3.96 X 10¹⁴ / R²

R² = 3.96 X 10¹⁴ / 20

= 1.98 x 10¹³ m

R= 4.45 x 10⁶ m

How does stress influence our immune system?
KengaRu [80]

Answer:

When you experience prolonged stress, your body needs those T-cells and white blood cells, and unfortunately, cortisol continues to suppress them, thus weakening your immune system over time.

Explanation:

Stress, Illness and the Immune System. ... When we're stressed, the immune system's ability to fight off antigens is reduced. That is why we are more susceptible to infections. The stress hormone corticosteroid can suppress the effectiveness of the immune system

What factors can cause an induced current in a wire loop through which a magnetic field passes?.
sp2606 [1]

The factors that  can cause an induced current in a wire loop are number of turns of the wire, area of the wire and magnetic field strength.

<h3>Induced emf</h3>

According to Faraday's law of electromagnetic induction, the rate of change of flux in a magnetic field is proportional to the flux through the magnetic field.

emf = dФ/dt

where;

  • Ф is magnetic flux = BA (magnetic field and area of the coil)

emf = N(BA)/dt

where;

  • N is number of turns

Thus, the factors that  can cause an induced current in a wire loop are number of turns of the wire, area of the wire and magnetic field strength.

A student solving a physics problem for the range of a projectile has obtained the expression r= v20sin(2θ)g where v0=37.2meter/
DedPeter [7]

Formula of range is given by

R = \frac{v_o^2 sin2\theta}{g}

here given that

v_0=37.2m/s

θ=14.1∘

g=9.80m/s^2

now by above equation

R = \frac{37.2^2 sin2*14.1}{9.80}

R = 66.7 m

so range will be 66.1 m
