Shear causes horizontal movement along a fault plane in a/n _______ fault. A. reverse B. strike-slip
C. normal
D. irregular

Answers

Answer 1
Answer: The answer is B. Strike slip fault. Shearing occurs when plates or blocks of rocks slide past each other in the opposite direction. This occurs at transform plate margins. An example is the San Andreas Fault running through California, USA. Compression occurs at reverse faults and tension at normal faults.
Answer 2
Answer: THE ANSWER IS B. STRIKE-SLIP

Answer:

Mac’s Speed = 2.5 m/s

Tosh’s Speed = 4 m/s

Tosh moves 1.5 m/s faster than Mac.

Explanation:

Tosh starts from an initial position of 12m and in a span of 3 seconds, (1.00 seconds to 4.00 seconds) he moves 12 meters.

So his speed is distance / time

s = 12 / 3

s = 4 m/s

Mac starts from an initial position of 2m and in a span of 4 seconds, he traveled 10m (2.00m to 12.00m).

Speed = Distance / time

s = 10 / 4

s = 2.5 m/s

Collect information about working of Geyser and prepare a report

Answers

A geyser is actually a devise that coverts electrical energy into heat energy for heating up water. The heating element that is inside the geyser actually gets heated up and then in turn it heats the water in contact with it within the geyser. There is also a thermostat device within the geyser that cuts off the heating when the water temperature reaches the desired level. This helps in stopping of electrical energy loss. One inlet brings in cold water while another outlet gets rid of the hot water. When the temperature of the water falls below the desired level the heating is again started by the thermostat.



suppose that you look into a photometer's eyepiece and the fluorescent disks appear to be equal in intensity. If the distance between the photometer to lamp 1 is 400mm, the distance between the photometer to lamp 2 is 200 mm, and the intensity of lamp 2 is known to be 15 candelas, what is the intensity to lamp 1?

Answers

Use the Inverse square law, Intensity (I) of a light is inversely proportional to the square of the distance(d).

I=1/(d*d)

Let Intensity for lamp 1 is L1 distance be D1 so on, L2 D2 for Intensity for lamp 2 and its distance.

L1/L2=(D2*D2)/(D1*D1)

L1/15=(200*200)/(400*400)
L1=15*0.25
L1=3.75 candela

Which statement is true about the loudness of sound?A. It is directly proportional to the distance of the listener from the source.



B. It is inversely proportional to the square of the distance of the listener from the source.



C. It is directly proportional to the square of the distance between the listener from the source.



D. It is inversely proportional to the distance between the listener from the source.

Answers

Answer : The correct option is, (B)

Explanation :

There is a direct relation between the loudness of sound and the intensity of sound.

L=10\log (I)/(I_o)         ..........(1)

where,

L = loudness of sound

I = intensity of sound

I_o = intensity of reference

From this we conclude that the loudness is directly proportional to the intensity of the sound.

There is an indirect relation between the intensity of sound and the distance of the listener from the source.

(I_1)/(I_2)=((d_2)/(d_1))^2          ...................(2)

From this we conclude that the intensity of sound is inversely proportional to the square of the distance of the listener from the source.

From equation (1) and (2) we conclude that the loudness of sound is inversely proportional to the square of the distance of the listener from the source.

Hence, the correct option is, (B)
Just like the gravitational force, the electrostatic force, the perceived
brightness of a light, and the strength of a radio station . . .

The loudness of a sound is inversely proportional to the square of
the distance between the observer and the source.

A device that uses electricity and magnetism to create motion is called a _________motor,magnet,generator . In a reverse process, a device that uses motion and magnetism can be used to create ________ light,electromagnetism,electricity

Answers

Answer:

1. motor

2. electricity

Explanation:

A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.

On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.

A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor
2nd Blank = Electromagnetism

The variable that is observed or measured during an experiment is called what type of variable?a. independent
c. controlling
b. manipulated
d. dependent

Answers

The correct answer for the question that is being presented above is this one: "d. dependent." The dependent variable is that one that is being measured in an experiment and which is influenced by the independent variable - the experiment measures the effect of the independent variable on the dependent variable.
