Which of the following can be determined by studying the spectrum of a star?the chemicals in the atmosphere of the star
the motion of the star
the temperature of the atmosphere of the star
all of the above

Answers

Answer:

all of the above

Explanation:

The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.

The right answer for the question that is being asked and shown above is that: "all of the above." the following that can be determined by studying the spectrum of a star includes: the chemicals in the atmosphere of the star; the motion of the star; the temperature of the atmosphere of the star.

Who experiences MORE force in her glove during a softball game, the catcher or the outfielder? Defend your answer. Use FΔT=mΔv in your explanation.

Answers

The catcher  experiences more force in her glove during a softball game than the outfielder during a softball game.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Given that: the equation of motion is:  FΔT=mΔv

Hence, Force = mass × change in velocity/time interval.

Now, during a softball game, the ball is in air more for the outfielder than  the catcher. Hence, from the given equation, the catcher  experiences more force in her glove during a softball game than the outfielder.

When the source of a sound is moving it's speed increases

Answers

That statement is false, and pretty meaningless ... we don't know
whether "its speed" refers to the source or the sound.

When the source of a sound is moving relative to the listener, then
the listener may hear a higher- or lower-pitch sound than what the
source is actually emitting.

Answer:

false

Explanation:

Viscous lidocaine 2% 30 mL Maalox (do not substitute Kaopectate) 60mL Diphenhydramine (use on hand stock 12.5mg/5mL elixir) 75 mg Carafate 1gm/10mL 40 mL The doctor wants the patient to use a daily dose of 2 teaspoons. How many doses are in the final product?

Answers

Answer:

There are approximately 16 dozes in the final product

Explanation:

The given parameters are;

The viscous lidocaine 2% 30 mL + Maalox 60mL + Diphenhydramine (12.5 mg/5mL elixir)75 mg + Carafate 1gm/10mL 40mL

The total volume becomes;

30 mL + 60 mL + 5 × 75/12.5 mL + 40 mL = 160 mL

1 Teaspoon = 4.928922 mL

Therefore, 2 teaspoon = 2 × 4.928922 mL = 9.857843 mL

Which gives;

The number of doses in 160 mL = 160 mL/(9.857843 mL) = 16.2307312 doses

Which is approximately 16 doses

Therefore, there are approximately 16 dozes in the final product.

The final product contains viscous lidocaine, Maalox, diphenhydramine, and Carafate. There are approximately 10.5 doses in the final product.

The final product is a mixture of viscous lidocaine, Maalox, diphenhydramine, and Carafate. The doctor wants the patient to use a daily dose of 2 teaspoons.

To calculate the number of doses in the final product, we need to determine the total volume of the mixture and divide it by the volume of a single dose.

First, add the volumes of the individual components: 30 mL + 60 mL + 75 mg + 40 mL = 105 mL

Since the doctor wants the patient to use 2 teaspoons (10 mL) per dose, divide the total volume of the mixture (105 mL) by the volume of a single dose (10 mL): 105 mL ÷ 10 mL = 10.5 doses

Therefore, there are approximately 10.5 doses in the final product.

Which type of wave can be transmitted through the vacuum of space ?

Answers

Answer: The correct answer is electromagnetic wave.

Explanation:

Electromagnetic wave is wave in which the electric field and the magnetic field are perpendicular to each other. Both fields are directed to the direction of the propagation of the wave.

Electromagnetic wave is transverse in nature. It travels with the speed of the light. It does not need medium to travel. It can be transmitted through the vacuum of space.

Therefore, the correct answer is electromagnetic wave.
