Does sound travel outside earth's atmosphere in space explain

Answers

Answer 1

On a large scale, no. Sound travels through space by the compression and relaxation of molecules. When you speak to someone on Earth, each inflection of voice compresses local molecules, and relaxes the molecules around the compressed ones. In space, however, the large lack of molecules means that the compression waves can’t be transmitted from the sound to the listener.

Which of the following are disadvantages of solar energy?

Answers

Final answer:

The disadvantages of solar energy primarily include its dependency on weather, need for large space, requirement of rare-earth minerals for photovoltaic cells, and potentially high costs.

Explanation:

The main disadvantages of solar energy are largely tied to its dependence on weather conditions and the requirement of considerable space. Solar energy generation is chiefly affected by cloud cover, nightfall, and incident angle strike at high altitudes that influence the amount of light energy available. While solar energy conversion does not necessarily require connection to large-scale power grids, making it beneficial for remote locations, it does rely on the creation of photovoltaic cells which require rare-earth minerals that can be difficult to obtain. Additionally, the price of solar energy, despite falling dramatically, may still present as a financial barrier for some.

Whenever a charged particle encounters a magnetic field, the particle tends to spiral around the magnetic field lines. as it does, it emits electromagnetic radiation. radiation produced in this way is called _______. the radiation is nonthermal, which means there is no link between the emission and the temperature of the radiating object. synchrotron radiation?

Answers

The electromagnetic radiation produced when a charged particle moves spirally in a magnetic field is called synchrotron radiation. This phenomenon occurs due to the fact the particle is accelerated radially (due to the presence of the magnetic field), and every charged particle when it is accelerated emits electromagnetic radiation.

One light-hour is the distance light travels in one hour. the speed of light is about 300,000 km/s (3 × 10^5km/s). if jupiter is 0.72 light hours from the sun, how far is this?

Answers

Answer:

Jupiter is [tex]7.776*10^8km[/tex] away from the sun.

Explanation:

The speed of light is [tex]3*10^5km/s[/tex]. This means, since there are 3600 seconds in an hour, the distance light travels in 1 hour is:

[tex]3*10^5*3600= 1.08*10^9km[/tex]

and this distance is called the light-hour.

Since Jupiter is 0.72 light-hours away from the Sun, its distance in km from the sun is:

[tex]1.08*10^8*0.72=7.7776*10^8km[/tex]

Thus, Jupiter is [tex]7.776*10^8km[/tex] away from the sun.

Two identical positive charges exert a repulsive force of 6.2 × 10−9 n when separated by a distance 3.7 × 10−10 m. calculate the charge of each. the coulomb constant is 8.98755 × 109 n · m2 /c 2 . answer in units of
c.

Answers

The electrostatic force between two charges is given by
[tex]F=k \frac{q_1 q_2}{r^2} [/tex]
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is their separation

In this problem, the two charges are identical, so we can call them q1=q2=q, and the formula becomes
[tex]F=k \frac{q^2}{r^2} [/tex]

Since we know the magnitude of the force and the separation between the two charges, we can re-arrange the equation to find the value of each charge:
[tex]q= \sqrt{ \frac{Fr^2}{k} } = \sqrt{ \frac{(6.2 \cdot 10^{-9} N)(3.7 \cdot 10^{-10}m)^2}{8.99 \cdot 10^9 Nm^2C^{-2}} }=3.07 \cdot 10^{-19} C [/tex]

Use Coulomb's Law formula to calculate the charge of each identical positive charge given the force and distance. Each charge is 4.0 × 10^-19 C.

We can use Coulomb's Law formula: F = k * (q^2) / r^2, where F is the force, k is the Coulomb constant, q is the charge, and r is the distance between the charges.

Given: F = 6.2 × 10^-9 N, r = 3.7 × 10^-10 m, and k = 8.98755 × 10^9 N · m^2 /C^2. Plugging these values into the formula, we get q = √(F * r^2 / k).

Calculating: q = √(6.2 × 10^-9 * (3.7 × 10^-10)^2 / 8.98755 × 10^9) = 4.0 × 10^-19 C.

Therefore, each charge is 4.0 × 10^-19 C.

ASAP Which of the following has kinetic energy? a. a rock poised for a fall b. an archer’s bow that is drawn back c. a rolling bowling ball d. a car waiting at a red light

Answers

The answer would be C.

Final answer:

The correct answer is c. a rolling bowling ball.

Explanation:

The correct answer is c. a rolling bowling ball.

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and velocity of the object. In this case, a rolling bowling ball has kinetic energy because it is moving. The other options do not involve motion and therefore do not have kinetic energy.

For example, a rock poised for a fall has only potential energy, as it does not possess motion. An archer's bow that is drawn back also has potential energy stored in the stretched bowstring, but it does not have kinetic energy until the arrow is released. A car waiting at a red light is stationary and not in motion, so it does not have kinetic energy.

An individual having difficulty with high blood pressure may be experiencing an imbalance in all of the following hormones except __________.
A. growth hormone (GH)
B. estrogen
C. norepinephrine
D. cortisol

Answers

The answer is; B

The fluctuation of estrogen in the body is common and its function in a cycle helps regulate the menstrual cycle in females. Therefore, its imbalance is not associated with blood pressure.

Growth hormone affects the renin-angiotensin system that influences blood fluid levels hence affects blood pressure. Norepinephrine is a neurotransmitter that affects dilation and vasoconstriction of blood vessels and the hearts rate hence affects blood pressure. Cortisol is a stress hormone and its increase in the body increases blood pressure. Cortisol is only produced in periods of stress and should not be produced in prolonged periods. Its imbalance, therefore, affects blood pressure.

the other answer is right, the right option is B. estrogen.

Windmills generate electricity by transferring energy from wind to a turbine

Answers

The complete question is reported in the attached picture.

1) The regression analysis was performed by the computer, in the output we have the coefficients we need: 0.137 and 0.240.
Therefore the equation of the least squares regression line will be:
[tex]\hat{y} = 0.137 + 0.240x[/tex]

where:
[tex]\hat{y}[/tex] = estimate of electricity production [A]
x = wind speed [mph]

2) Let's apply the previous formula to our cases:
x = 25 --> [tex]\hat{y}[/tex] = 0.137 + 0.240(25) = 6.137 A
x = 15 --> [tex]\hat{y}[/tex] = 0.137 + 0.240(15) = 3.737 A

The difference is 6.137 - 3.737 = 2.4 A

The windmill would be expected to produce 2.4 A more when the wind speeds at 25mph with respect to when the wind speeds at 15 mph.

3) The proportion of variation in electricity production explained by the linear relationship with the wind speed is given by the R-Sq value, which is 0.873.

Hence, the linear relationship between electricity production and wind speed explains the 87.3% of the variation in production.

4) The text says that the assumptions were checked. The computer performed all the calculations, finding as t-score for wind speed:
T = Coef / SE Coef = 0.240 / 0.019 = 12.63
which was converted to a p-value:
P = 0.000

Therefore, being p <0.05, the null hypothesis can be rejected and we can say that electricity production by the windmill is related to wind velocity.

____________________

The magnetic field strength is directly proportional to the current through the circuit. When the voltage is increased, current also increases, results in a rise in magnetic field strength. Thus, option A is correct.

What is magnetic field?

A magnetic field is the field produced by the magnetic flux or field lines with a magnitude and direction. A magnetic field is always associated with an electric field where, the magnitudes of both field are in direct proportion.

The magnetic field lines will be perpendicular to the electric flux. According to Ohm's law, voltage and current through a circuit are directly proportional to each other.

As the voltage in a circuit is increased, the current through it increases which n turn result in a hike in magnetic field strength. Therefore, when 1.5 volt is changed by 9 volt battery in the circuit, magnetic field strength would increase.
