Determine the gravitational energy of your 2 kg physics binder if it is sitting on the ground (height= 0
meters)
Answers
Answer:
0J
Explanation:
The gravitational potential energy of the body is 0J because the height is at 0m.
Gravitational potential energy is a form of energy which is highly dependent on the position of a body. The relative position of a body in space accounts for the amount of gravitational potential energy they posses.
A body at height 0m has no gravitational potential energy:Gravitational potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity
h is the height
So, if h = 0, Gravitational potential energy will become 0.

A soccer ball was kicked off the roof of a building going
20m/s. It took 5 s for the soccer ball to hit the ground?
Find the vertical final velocity, the distance the ball
traveled horizontally, and the height the ball fell.
Answers
Answer:
Final vertical velocity = -29m/s
Horizontal distance = 100m
Height = 20.41m
Explanation:
1. The vertical final velocity can be calculated thus: vy = vyo - gt
Where;
vy = vertical velocity (m/s)
vyo = vertical initial velocity (20m/s)
g = acceleration due to gravity (9.8m/s²)
t = time (5s)
Hence, vy = vyo - gt
vy = 20 - (9.8 × 5)
vy = 20 - 49
vy = -29m/s
2. x = V0 x t
Where;
x = horizontal distance (m)
Vo = initial velocity
t = time (s)
x = 20 × 5
x = 100m
3. Maximum height = (voy)²/2g
= 20²/ 2 × 9.8
= 400/19.6
= 20.41m
Pretty cool, the atoms that exist in your body are some of the same atoms that have existed since the beginning of the universe. You are made of star stuff. What scientist made this observation?
1) Neil Degrasse Tyson
2) Albert Einstein
3) Carl Sagan
Answers
Answer:
Your answer is option 3
Explanation:
The statement is that the atoms that exist in our body are the same number of atoms that existed at the beginning of the universe. This statement is said by Carl Sagan. Hence, option (3) is correct.
What is an atom?The atom is the smallest form of matter that can be separated without releasing particles with electrical charge. It is also the smallest material with chemical element-like properties. As a reason, the atom is the basic unit of chemistry.
The most of an atom is made up of space. The remainder consists of a cloud of electrons with negative charge orbiting a positive electrode nucleus composed of protons and neutrons. The nucleus is small and dense in comparison to electrons, the lowest charged particles in nature. Electric forces, which connect electrons to the nucleus of atoms, pull electrons to any positive charge.

Why does the comet have tails
Answers
Answer:
Comets leave long beautiful tails when they come close to the sun. ... But when it approaches the sun, the heat evaporates the comet's gases, causing it to emit dust and microparticles (electrons and ions). These materials form a tail whose flow is affected by the sun's radiation pressure.

A wheel with radius r rotates freely about its axle with initial angular speed ωi. A point on the wheel's rim moves at linear speed v.
Suddenly, the wheel accelerates so the point moves at linear speed 3v. The final angular speed is ωf.
How does the angular speed of the wheel change?
Answers
Answer:
[tex]\dfrac{2\omega_i}{t}[/tex]
Explanation:
r = Radius of wheel
v = Initial linear speed
3v = Final linear speed
Initial angular speed is given by
[tex]\omega_i=\dfrac{v}{r}[/tex]
Final angular speed after time [tex]t[/tex] is given by
[tex]\omega_f=\dfrac{3v}{r}\\\Rightarrow \omega_f=3\dfrac{v}{r}=3\omega_i[/tex]
The angular acceleration of the wheel will give us how the angular speed of the wheel changes.
From the equations of rotational motion we have
[tex]\omega_f=\omega_i+\alpha t\\\Rightarrow 3\omega_i=\omega_i+\alpha t\\\Rightarrow \alpha=\dfrac{3\omega_i-\omega_i}{t}\\\Rightarrow \alpha=\dfrac{2\omega_i}{t}[/tex]
The acceleration wheel is [tex]\dfrac{2\omega_i}{t}[/tex].

Which of the following would double the resistance in a wire?
a. Double the mass of the wire
b. Double the length of the wire
c. Half the mass of the wire
d. Half the length of the wire
Answers
Answer:
b. Double the length of the wire
Explanation:
I just took the test.
When we Double the length of the wire would double the resistance in a wire would double. The correct option is B.
What is resistance?Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for variation in resistance with length is given by
R = ρ*L/A
where r is resistance
ρ is the resistivity constant for
L is the length of the wire
A is an area of the cross-section for the wire
As evident from the above relation that resistance is directly proportional to the length of the wire keeping other parameters constant
Thus, by Doubling the length of the wire the resistance of the wire will be doubled, therefore the correct answer is B.

Gravity is the fundamental attraction force which acts among all material.
