Please help ASAP...A satellite takes 24 hours to complete one orbit whilst travelling at a speed of 12 km/s. at what height above the earth is the satellite orbiting. Thank you :)

Answers

Answer 1

Answer: By mentioning space, satellites, and orbits, the question is trying to convince you that your brain can't operate because there is no oxygen. Try thinking about the question this way: If it takes you 24 hours to travel around a circle, at the speed of 12 km/sec, then what's the radius of the circle ?

Maria and Ben are both suffering from a hereditary disease, as described in the following table.Description of Disease

Patient Description

Maria Blood cells get stuck in blood vessels, causing painful attacks

Ben Hemoglobin is abnormal due to curved shape of red blood cells

Which disease(s) are Maria and Ben suffering from?

a)Both are suffering from type 1 diabetes.

b)Both are suffering from sickle cell anemia.

c)Maria is suffering from sickle cell anemia and Ben from type 1 diabetes.

d)Maria is suffering from type 1 diabetes and Ben from sickle cell anemia.

Answers

The symptoms of Maria and Ben indicates that they are both suffering from sickle cell anemia.

What is sickle cell disease?

Sickle cell disease is a disease of the blood in which the red blood cells produce abnormal hemoglobin which gives the red blood cell a sickle shape and makes them not to efficiently transport oxygen and to get stuck in the capillaries.

Sickle cell disease is a hereditary disease.

Therefore, bassed on their symptoms Maria and Ben are both suffering from sickle cell anemia.

the answer is option B

A person is rowing across the river with a velocity of 4.5 km/hr northward. The river is flowing eastward at 3.5 km/hr (Figure 4). What is the magnitude of her velocity ( v ) with respect to the shore?

Answers

The magnitude of her velocity with respect to the shore will be 5.70 Km/h. The change of displacement with respect to time is defined as velocity.

What is velocity?

Velocity is defined as the change in displacement with respect to time. The quantity of velocity is a vector quantity. It is a component that is time-based. It is measured in meters per second.

The given data in the problem is;

Q is the magnitude of Velocity of the boat = 4.5 km/hr

P is the magnitude of Velocity of the river flowing = 3.5 km/hr

R is the resultant of velocity P and Q=?

θ is the angle between the two velocities = 90°

From the law of vector addition;

$\rm R= √(P^2+Q^2+2PQcos\theta) \n\n \rm R= √((3.5)^2+(4.5)^2+2* 3.5 * 4.5 cos90^0) \n\n \rm R=5.70 \ m/sec$

Hence the magnitude of her velocity with respect to the shore will be 5.70 Km/h.

Answer: The magnitude of her velocity ( v ) with respect to the shore is 5.70 km/h.

Explanation:

Magnitude of Velocity of the boat = Q

Magnitude of Velocity of the river flowing = P

R = Resultant velocity due to velocity of boat and velocity of river.

Applying Law of triangles of vector addition :

$R=√(P^2+Q^2+2PQCos\theta)$

From the figure attached:

P = 3.5 k/h, Q = 4.5 km/h

$\theta= 90^o$

$R=√(P^2+Q^2+2PQCos\theta)=√((3.5)^2+(4.5)^2+3.5* 4.5* cos90^o)=5.70$

$(Cos90^o=0),(sin 90^o=1)$

$\alpha =tan^(-1)(Qsin\theta)/(P+Qcos\theta)=tan^(-1)(4.5 sin 90^o)/(3.5+4.5 cos90^o)=tan^(-1)(4.5)/(3.5)=52.12^o$

The magnitude of her velocity ( v ) with respect to the shore is 5.70 km/h.

Compare and contrast ultraviolet light with infrared light using wavelength, frequency, and energy.

Answers

Ultraviolet light has a shorter wavelength (in its majority), higher frequency and emits higher amounts of energy than infrared. More specifically, the UV and infrared values are shown below: Ultraviolet Wavelength: From 10 nm to 380 nm Frequency: From 30 PHz to 750 THz Energy: From 3.1 eV to 124 eV Infrared Wavelength: From 1 mm to 750 nm Frequency: From 300 GHz to 430 THz Energy: From 0.0012 eV to 1.65 eV

Final answer:

Ultraviolet light has a shorter wavelength and higher frequency than infrared light. It also has more energy. Violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Infrared radiation, on the other hand, has longer wavelengths and lower frequencies than violet light.

Explanation:

Ultraviolet light and infrared light are both forms of electromagnetic radiation, but they differ in terms of wavelength, frequency, and energy. Ultraviolet light has a shorter wavelength and higher frequency compared to infrared light. As a result, ultraviolet light has more energy than infrared light.

For example, violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Ultraviolet radiation extends from about 400 nm to 10 nm and is produced by atomic and molecular motions and electronic transitions. In contrast, infrared radiation has longer wavelengths and lower frequencies than violet light.

It's important to note that shorter-wavelength ultraviolet light can cause damage to living cells and is better able to cause materials to fluoresce compared to visible light. On the other hand, infrared radiation is often associated with heat and is used for various purposes, such as remote control communication and thermal imaging.
