Answer:

6 V

Explanation:

By ohm's law :

V = IR

V = 0.2 × 30 = 6 V

Answer:

V=6V

Explanation:

Use the equation I=V/R and solve for V then use V=IR plug in the numbers.

V=IR

V=30(0.2)

V=6V

Answer:

Food, wind, water.

Explanation:

This is supposed to be a personalized question so I answered with things that can make/give energy.

Answer:

This is personal question, very interesting! Depend on who is the person, where the person is working at, how old is that person - we can have various answers.

Personally, I think first about that human and other animals needs energy to survive, that means we need to eat, to drink; The plants need energy to survive too - that is the energy from the Sun.

Secondly, the human being needs such types of energy as electricity, wind, solar energy, etc. in oder to live. Even the acient people learnt to use solar and wind and water - natural energy from the nature.

Thirdly, the human being needs spiritual energy to have a good life.

Another specific terms of energy related to physics and chemistry, and even biology - actually are not in my mind in everyday life.

Explanation:

Answer: A.

The space contains a magnetic field

Explanation:

A charged particle is surrounded by electric field and exerts force on other charges in the field, attracting or repelling them. 

But a charged particles in a magnetic field can escape into infinity without ever stopping due to magnetic force. We can therefore conclude that the space contains a magnetic field

Answer:

Explanation:

B

Answer:

x is positive y is negative

Explanation:

because the ones from x are moving away from it and the ones from are moving towards it

Answer:

x pos y neg

Explanation:

yes

Answer:

The answer would be the first option. This occurs because of the presence of the protons. The positive charge of protons and the negative charge of electrons set the balance of each other and usually the net charge turn out to be zero.

Answer:

A magnetic field does not exert a force on particles traveling parallel to the magnetic field.

Explanation:

This is the PLATO answer.

Answer:

Difference

Explanation:

The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.

If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.

Answer:

the answer is A force is a push or pull that changes the motion of an object. Forces can make objects start or stop moving, cause objects that are already moving to speed up or slow down, or make objects change direction. Force arrows are used to represent both the magnitude and direction of forces.

Answer:

R =0.672 ohms

Explanation:

We have,

Length of a gold wire is 6 m

Resistivity of gold is [tex]5.6\times 10^{-8}\ \Omega-m[/tex]

Area of cross section of the wire is [tex]5\times 10^{-7}\ m^2[/tex]

The resistance of a wire is given by the relation as follows :

[tex]R=\rho\dfrac{l}{A}\\\\R=5.6\times 10^{-8}\times \dfrac{6}{5\times 10^{-7}}\\\\R=0.672\ \Omega[/tex]

So, the resistance of the gold wire is 0.672 ohms.

Answer: Light energy only travels through empty space absent of mass energy and kinetic energy only travels through a medium full of mass energy. ... Waves don't transfer mass because mass is not the same as a wave. Mass can hold “extra” energy but it is that energy that moves through it as a wave, not the particle itself.

In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position.

Answer:

Focal length, f = 10 cm

Explanation:

We have,

A concave mirror forms a real image at 15.0 cm from the mirror surface along the principal axis, it means that the image distance is 15 cm

The object is placed at a distance of 30 cm, u = -30 cm

It is required to find the focal length of the mirror. Let it is f. Using mirror's formula to find it:

[tex]\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{15}-\dfrac{1}{(-30)}=\dfrac{1}{f}\\\\f=10\ cm[/tex]

So, the focal length of the mirror is 10 cm.

Answer:

Chromosphere

Explanation:

It is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilmoeters deep.It's rosy red color is only apparent during eclipses.The chromosphere sits just above the photosphere and below the solar transtion region.

Answer:

Explanation:

Oxygen and carbon dioxide

6.

Answer:

45 meters

Explanation:

notice that is you multiply the time with the speed the units cancel to get distance.

therefore

distance=velocity(time)

distance=(3)15

distance =45 meters

7.

Answer:

1. the speed is constant

2. the average speed is .5 m/s

Explanation:

I have attached a graph of the data in excel.

from excel i got the equation of the line to be y=.5x with y being distance and x being time.

the function is a position function so if you take the derivative of it you get the velocity which is .5.

since the derivative is a constant the the speed does not change and the average velocity is the derivative.

Answer:

D) 1000 m/s

Explanation:

[tex]wavelength = \frac{velocity}{frequency}[/tex]

You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

Hope this helps.

Answer:

It lasted two hours or 120 minutes, it would be smart to say that he was riding up it during the interval 20-60min and riding down it during the interval 60-80min. This is an assumption made because of his speed, when going up a hill our speed is slower while when riding down it, you gain a lot of speed.
