A. An iceberg
B. A plateau
C. A rift valley

Answers

Answer: C

Explanation:

Divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.

What will be left of the sun after it dies?

Answers

Answer:

Our star is powered by nuclear fusion, and it turns hydrogen into helium in a process that converts mass into energy. Once the fuel supply is gone, the sun will start growing dramatically. Its outer layers will expand until they engulf much of the solar system, as it becomes what astronomers call a red giant.

Explanation:THERE YOU GO

Answer:

Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf. All the outer material will dissipate, leaving behind a planetary nebula. "When a star dies, it ejects a mass of gas and dust — known as its envelope — into space.

1. It takes Tiffany 0.25 hours to get to school in the mornings. She lives 4.5 miles away
from the school. At what speed is she traveling to get there?

Answers

Answer:

0.05

Explanation:

u just divide 0.25/4.5 and u get that

If  It takes Tiffany 0.25 hours to get to school in the mornings. She lives 4.5 miles away from the school, then the speed of traveling off the Tiffany would be 28.96 kilometers per hour.

What is speed ?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

As given in the problem we have to find the speed  It takes Tiffany 0.25 hours to get to school in the mornings. She lives 4.5 miles away from the school,

Speed of traveling = total distance traveled by the Tiffany / Total time

Speed of traveling = 4.5 × 1.609 / 0.25

                               = 28.96 kilometers per hour

Thus,  the speed of traveling off the Tiffany would be 28.96 kilometers per hour .

10 Kg box rest on 30 degree incline and begins to slide down.(a) What is the acceleration if no friction is present?(b) What is the acceleration if the coefficient of kinetic friction is 0.2?(c) What is the final speed of box when it reaches the bottom of an incline that is 200 m length? (use the acceleration in part b)

Answers

( a) The acceleration of the box in the absence of friction is 8.49 m/s².

(b) The acceleration of the box in the presence of friction is 1.7 m/s².

(c) The speed of the box at the bottom of the incline is 18.44 m/s.

What is the acceleration of the box in absence of friction?

The acceleration of the box if no friction is present is calculated by applying Newton's second law of motion.

mg cosθ = ma

g cosθ = a

where;

g is acceleration due to gravityθ is the angle of inclination of the ramp

The acceleration of the box in the absence of friction is calculated as;

a = ( 9.8 ) x ( cos 30 )

a = 8.49 m/s²

The acceleration of the box in the presence of friction is calculated as;

Ff = ma

where;

Ff is the force of friction

μmg cosθ = ma

μg cosθ = a

( 0.2 x 9.8 x cos 30 ) = a

1.7 m/s² = a

The speed of the box at the bottom of the incline is calculated as follows;

v² = u² + 2ah

where;

u is the initial velocity of the box = 0h is the vertical height of fall of the boxa is the acceleration of the box

v² = 0 + 2ah

v = √ ( 2ah )

h = L sinθ

v = √ ( 2 x a x L sinθ )

v = √ ( 2 x 1.7 x 200 x sin 30 )

v = 18.44 m/s

A force applied at an angle causes an object to move horizontally only force which is parallel to motion does work.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force.

An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

A force applied at an angle causes an object to move horizontally only force which is parallel to motion does work.

To construct a non-mechanical water meter, a 0.500-T magnetic field is placed across the supply water pipe to a home and the Hall voltage is recorded.

Required:
a. Find the flow rate through a 3.00-cm-diameter pipe if the Hall voltage is 60.0 mV.
b. What would the Hall voltage be for the same flow rate through a 10.0-cm-diameter pipe with the same field applied?

Answers

Answer:

a.  4 m/s b. 0.2 V

Explanation:

a. Find the flow rate through a 3.00-cm-diameter pipe if the Hall voltage is 60.0 mV.

The hall voltage V = vBd where v = flow-rate, B = magnetic field strength = 0.500 T and d = diameter of pipe = 3.00 cm = 0.03 m

Since V = vBd

v = V/Bd    given that V = 60.0 mV = 0.060 V, substituting the values of the other variables, we have

v = 0.060 V/(0.500 T × 0.03 m)

v = 0.060 V/(0.015 Tm)

v = 4 m/s

b. What would the Hall voltage be for the same flow rate through a 10.0-cm-diameter pipe with the same field applied?

Since the hall voltage, V = vBd and v = flow-rate = 4 m/s, B = magnetic field strength = 0.500 T and d' = diameter of pipe = 10.0 cm = 0.10 m

Substituting the variables into the equation, we have

V = vBd

V = 4 m/s × 0.500 T × 0.10 m

V = 0.2 V

1. A boulder fell from a small cliff and accelerated towards a car below at 9.8 m/s^2. The
boulder smashed into a car with a force of 99,000 Newtons. What is the mass of the
boulder?

Answers

Answer:

Mass = 10102.04 kilograms.

Explanation:

Given the following data;

Acceleration = 9.8m/s²

Force = 99000N

To find the mass;

Mass = force/acceleration

Mass = 99000/9.8

Mass = 10102.04 kilograms.

Therefore, the mass of the boulder is 10102.04 kilograms.
