Answer:
According to newtons first law of motion an object remains in its state of rest or motion in a straight line unless an external unbalanced forces acts upon it. This is the reason why Newtons first law of motion is often called the LAW OF INERTIA

Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator. tafu models its position with the function p(t)= t2 t â 1 where t>1. in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. (a) calculate the limit
Answer:
Infinity
Explanation:
When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.
We have that for the Question, it can be said that in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. the limit is
[tex]Lim_{t->\infty} p(t)= \infty[/tex]
From the question we are told
Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator.tafu models its position with the function
p(t)= t2 t â 1 where t>1.
in the limit calculations below, if you need to use -â or â, enter -infinity or infinity.
(a) calculate the limit
Generally the equation for the Question is mathematically given as
[tex]p(t)=\frac{t^2}{t-1}\\\\Therefore\\\\For Lim_{\infty}\\\\We have\\\\ Lim_{t->\infty} p(t)= Lim_{t->\infty}\frac{t^2}{t-1}\\\\[/tex]
Since, the equivalent degree of numerator (t^2) is greater than that of the denominator

How does the sun maintain its high temperature and energy output?
Answer:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.
Explanation:
I got you
By not running out of fuel (Hydrogen).
Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.
If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Power = [tex]\frac{670}{60}[/tex] = 11.2Watts
Is a violin and battery potential energy?
Explanation:
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.

A bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J

A. As a nebula
B. As a galaxy
C. As a planet
D. As a solar system
The NGC 3603 region of space is shown below. It is a cloud of gas and dust. Stars are forming in this cloud. The NGC 3603 be classified as a nebula. The correct option is A.
What is a nebula?A tiny, ball-shaped nebula is known as a planetary nebula. It generates an ionized gas that is luminous. Large and typically erratic clouds are produced by diffuse nebulae.
Due to their big stars, they typically form a cluster of stars. a cloud of gas in space that can be seen in the night sky as a vaguely discernible brilliant patch, as something black, or as a shadow against other luminous objects.
Dust and gases, primarily hydrogen and helium, make up nebulae. The mass of gas and dust eventually grows so large that it is forced to collapse by gravity. The material in the cloud's core heats up as a result of the collapse, and this hot core is the start of a star.
Therefore, the correct option is A. As a nebula.

Answer:
D
Explanation:
The density has a formula of d = m / V.
The volumes are given as the same.
The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.
A: incorrect. If the volumes are the same, the density is not the same because the masses are different.
B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.

A satellite is in orbit 36000km above the surface of the earth. Its angular velocity is 7.27*10^-5 rad/s. What is the velocity of the satellite? (The radius of the earth is 6400km.)
Answer:
v = 3.08 km/s
Explanation:
Given that,
The angular velocity of the satellite = [tex]\omega=7.27\times 10^{-5} rad/s[/tex]
A satellite is in orbit 36000km above the surface of the earth.
The radius of the earth is 6400 km
Let v is the velocity of the satellite. It can be calculated as :
[tex]v=r\omega\\\\v=(36000\times 10^3+6400\times 10^3)\times 7.27\times 10^{-5}\\\\v=3082.48\ m/s\\\\v=3.08\ km/s[/tex]
So, the velocity of the satellite is 3.08 km/s.
