Answer;

D. where two plates collide

Explanation;

-Subduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. This process results in geohazards, such as earthquakes and volcanoes.

-Subduction zone volcanism occurs where two plates are converging on one another. One plate containing oceanic lithosphere descends beneath the adjacent plate, thus consuming the oceanic lithosphere into the earth's mantle. This on-going process is called subduction.

Subduction: the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate. so, subduction would occur where two plates meet, or collide, making the answer D.

5. A cheetah with a mass of 70 kg was clocked running at 72 mph (32 m's). How many joules of
blsea [12.9K]

Answer:

Kinetic energy = 35840 Joules

Explanation:

Given the following data;

Mass = 70kg

Velocity = 32m/s

To find the kinetic energy;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

K.E = \frac{1}{2}MV^{2}

Substituting into the equation, we have;

K.E = \frac{1}{2}*70*32^{2}

K.E = \frac{1}{2}*70*1024

K.E = 35 * 1024

K.E = 35840 Joules.

Therefore, the kinetic energy possessed by the cheetah is 35840 Joules.

What is the purpose of the lenses in a camera? a. Send light to the eyepiece c. Make the picture color or black and white b. Foc
aliya0001 [1]
The lenses on a camera focus the light entering the camera and provide a clear, sharp image at the location of the film or CCD device. If you took the lenses off a camera designed for use with lenses, you would not be able to create a usable image.

A heat pump operates on a Carnot heat pump cycle with a COP of 8.7. It keeps a space at 248C by consum-ing 2.15 kW of power. Det
Marizza181 [45]

Answer:

<em>Heat of the reservoir is 461.38 K or 188.1 °C</em>

<em>The heating load is 18.705 kW</em>

Explanation:

COP = 8.7

working temperature T_{h} = 248 °C = 248 + 273.3 = 521.3 K

work power W = 2.15 kW

reservoir temperature T_{c} = ?

heating load Q = ?

We know that

COP = Q/W

Q = COP x W = 8.7 x 2.15 = <em>18.705 kW</em>

Also,

COP = \frac{T_{h} }{T_{h}- T_{c}  } = \frac{521.3}{521.3- T_{c}  }

8.7 = \frac{521.3}{521.3- T_{c}  }

4535.31 - 8.7T_{c}  = 521.3

4535.31 - 521.3 = 8.7T_{c}  

4014.01 = 8.7T_{c}  

T_{c}  = 4014.01/8.7 = <em>461.38 K</em>

or 461.38 -273.3 = <em>188.1 °C</em>

A person is standing on top of a cliff and falls down. If he takes 3.7 s to hit the ground, how high up is the cliff?
Maksim231197 [3]

Answer:

h = 67.081 m

Explanation:

Given that,

The time taken by a person to fall down is, t = 2.2 s

The height of the cliff from the ground, h = ?

The distance that the person will fall through the time is given by the formula

                               S = 1/2 gt²  m

Where,        

                             g - acceleration due to gravity

Substituting the values in the above equation

                              S = 1/2 x 9.8 m/s² x (3.7 s)²

                                 = 67.081  m

Therefore, the height of the cliff from the ground is, h = 67.081  m
