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.
PLEASE MARK ME BRAINLIEST, PLEASE1. 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 rampThe 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 frictionμmg 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 boxv² = 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

The document you upload for this should show how you solved the problem as well as the final answer and correct unit for the answer.
Is this a step-up transformer or a step-down transformer? Explain how you know which type it is. The document should have a short description of how you know what type of transformer is being described in this prompt. Make sure to use complete sentences and to use proper language mechanics in your response.

Answer:
I hope this helps.
Explanation:
Vs/Vp = Ns/Np
Vs/9 = 30/300
Vs/9 = 1/10
Vs= 9/10 = 0.9 volts
It is a Step down transformer. This is because the number of turns on the primary coil is greater than that on the secondary coil.

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

Actually Welcome to the Concept of the Work, energy and power.
Potential energy = m*g*h, here g = 9.8 m/s^2 (universal value)
hence, h = P/m*g
==> h = 74/ 5*9.8
===> h = 74/49
==> h = 1.51 meters
hence the height is 1.51 m

Explanation:
a. 123.517 to 2 decimal places
⇒ to 2 decimal places = 123.52 ( round 7 to 1 since it is up to 5 and add it to 1 before it.)
b. 14.328 km/hr to one decimal place.
⇒ to 1 decimal place = 14.3 (round 8 to 1 since it is up to 5 and add it to 2 before it, the 2 becomes 3, round the 3 to 0 since it is less than 5)
c. 0.00934 m to 3 decimal places.
⇒ to 3 decimal place = 0.009
