(a) The height above the earth's surface of the parking orbit is determined from the difference between the orbital radius and earth's radius (h = r - R).

(b) Velocity of the satellite of the earth is determined with a formula given as  (2π/T)r.

<h3>Height above the earth's surface </h3>

The height above the earth's surface is calculated using the following formula;

T = \frac{2\pi r^{\frac{3}{2} }}{\sqrt{Gm} }

where;

  • T is time period of the satellite
  • r is orbital radius

r = h + R

h = r - R

where;

  • h is height above the earth's surface
  • R is radius of earth
<h3>Velocity of the satellite</h3>

The velocity of the satellite is determined using the formula below;

v = ωr

v = (2π/T)r

Mike has swelling in his nasal and sinus tissues. What type of medication will help him with this condition?
krok68 [10]

Aromatherapy based treatment can offer impermanent help when nasal and sinus tissue drainage blockage and pressure for Mike.

<u>Explanation:</u>

Nasal and sinus tissues provide stuffy nose and pain or pressure in several areas around the face or teeth. There's normally a nasal release that might be yellow, green, or clear. You may likewise have exhaustion, the issue with a feeling of smell or taste, hack, sore throat, terrible breath, migraine, torment when you twist forward, and fever.

For this issue, Mike can utilize Aromatherapy based treatment that can offer some quick help with discomfort on the blocked nose and migraine. During this stage, mike ought to breathe in some restorative or common smell to control his sufferings. Fragrance, for example, Peppermint, Eucalyptus, Tea tree, Oregano, Clary wise, Lavender, Rosemary, and so forth are a great idea to breathe in.

How much work do you need to do if you use a force of 3 Newtons to move a table 25 meters?
Harlamova29_29 [7]

The work needed if a force of 3N is used to move a table 25 metres is 75Nm (joules).

<h3>How to calculate work done?</h3>

Work is a measure of energy expended in moving an object. This means that no work is done if the object does not move.

Force is a physical quantity that denotes the ability to push, pull, twist or accelerate a body and which has a direction and is measured in Newtons.

Work done on an object can be calculated by multiplying the force applied to move the object by the distance the object moves as follows:

Work done = Force (N) × distance (m)

According to this question, a force of 3 Newtons is used to move a table over a distance of 25 meters. The work done on the table can be calculated as follows;

W = 3N × 25metres

W = 75Nm

Therefore, 75Nm is the work done on the table.

Len [333]

Answer:

D. Nothing will happen; the seesaw will still be balanced.

Explanation:

D. Nothing will happen; the seesaw will still be balanced. Since both toruqes or momentums respect to the center have changed in the same amount (one-half their original distance) the seesaw will remain balanced, if the children change distance in a different amount then it will be out of balance

In an experiment you measure a first-order red line for Hydrogen at an angle difference of ΔΘ = 22.78o. The diffraction grating
azamat

Answer:

a) wavelength = 656.3 nm

b)  the value of Rydberg's constant for this measurement is 1.097 × 10⁷ m⁻¹

Explanation:

Given that;

angle of diffraction Θₓ = 22.78°

incident angle Θ₁ = 0

slit separation d  = 5900 lines per cm = 1/5900 cm = 10⁻²/5900 m = 0.01/5900 m

order of diffraction n = 1

wavelength λ = ?

to find the wavelength, we use the expression

λ = d (sinΘ₁ + sinΘₓ) / n

To find the wavelength λ;

λ = 0.01/5900 × (sin0 + sin22.78° )

λ = 6.5626 × 10⁻⁷ m

λ = 656.3 x 10⁻⁹ m

∴ λ = 656.3 nm

b)

According Balnur's  series spectral lines; n₁ = 3, n₂ = 2 and

λ = R [ 1/n₂² - 1/n₁²]

where  R is Rydberg's constant

from λ = R [ 1/n₂² - 1/n₁²]

R = 1/λ [n₂²n₁² / n₁² - n₂²]

R = 10⁹/ 656.3 [ 9 × 4 / 9 - 4 ]

R = 1.097 × 10⁷ m⁻¹

Therefore the value of Rydberg's constant for this measurement is 1.097 × 10⁷ m⁻¹
