Answer 2

Elements are arranged in the periodic table based on various patterns. For example, the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na). Option A is correct.

What is periodic table ?

The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.

They are organized in a tabular format, with a row representing an era and a column representing a group.

Elements are ordered in increasing atomic number order from left to right and top to bottom.

Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.

Elements are arranged in the periodic table based on various patterns. For example the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na).

Hence, option A is correct.

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.

a car has a mass of 12,000 kg. What is it’s acceleration when the engine exerts a force of 600 N? (Formula: F=ma)

Answers

the answer to this is .05

m = 12000kg
F = 600N

F = ma

substitute for them and you'll get

600 = 12000a

____________________

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.

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.

what do waves transmit?

Answers

Waves transmit energy

Answer:

Waves only transport a portion of energy.

Explanation:

Let's think about some examples related to waves in nature:

An electromagnetic wave is a combination of electric and magnetic fields, both of them oscillate through space and time. That oscillation transport energy, that is bounded in little "packets" of energy called photons. So this wave transmits energy.In the case of a solid, the periodic oscillation of the molecules, this kind of oscillation transport energy too and in this particular case it is called phonons. It is just a quantum of energy related to a compression wave, as a sound or a vibration lattice in a crystal.

In conclusion, waves only transport a portion of energy.

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.

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.

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.

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.

On a large scale, no. Sound travels through space by the compression and relaxation of molecules.

In space, however, the large lack of molecules means that the compression waves can’t be transmitted from the sound to the listener.
