Answer:
Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion. ... If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.
In steam engine , pistons remove some heat energy from hot gases and then uses these moving pistons to power the device attached that is hooked up . This is how heat energy can be converted to kinetic energy.

What is Heat/Thermal energy ?
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another.

You attach a cart with a mass of 0.92 kg to a spring and compress the cart-
spring system. The spring constant for the spring is 130 N/m. Your objective is
to propel the cart with a velocity of 1.4 m/s along a frictionless surface. How
need to compress the spring in order to meet your target velocity?
far do
you
Answer:
F = - K X force exerted by compressed spring
F X = 1/2 M V^2 energy (work) required to produce a speed V for mass M
K X * X = 1/2 M V^2 direction of F is the same as that of V
X^2 = M V^2 / K combining terms
X = (M / K)^1/2 V
X = (.92 / 130)^1/2 * 1.4 = .118 m

If the static frictional coefficient is pls
0.74, what is the force of static friction?
=
Hi there!
We know that the MAXIMUM static friction force to be overcome is:
Fs (Force of Static Friction) = μN (Normal Force)
The normal force is equal to the weight of the block AND the vertical component of the applied force, so:
N = Mg + Fasinθ
Plug in the given values:
N = 26.8(9.81) + (89.2)sin(38) = 317.825 N
Multiply by the force of static friction to derive the static force:
0.74 * 317.825 = 325.191 N <-- MAXIMUM STATIC FRICTION FORCE
The force applied, if not greater than this value, will result in an EQUAL and OPPOSITE static frictional force. Thus:
Fs = Horizontal component of the applied force
Fs = 89.2cos(38) = 70.291 N
Calculate the acceleration of the object as it slides down the incline plane.
Answer:
0.788 m/s²
Explanation:
Ff = 0.1 × 5 kg × 10 m/s² × cos 38°
Ff = 5 N × 0.788
Ff = 3.94 N
F = m × a
3.94 N = 5 kg × a
a = 3.94 N / 5 kg
a = 0.788 m/s²

Figure 10.20 in your textbook shows an energy diagram for a system with total energy E1. Suppose the system's total energy is E2 = (1/3)E1. In what ways could the particle move?
Select all that apply.
a.) It could remain at rest at x3.
b.) It could oscillate between x1 and x5.
c.) It could undergo small oscillations around x2.
d.) It could undergo small oscillations around x3.
e.) It could undergo small oscillations around x4.
Please explain why, I have an exam coming up and want to understand the concept.
The particles can undergo small oscillations around x₂.
The given parameters;
initial energy of the particles = E₁final energy of the particles, E₂ = 0.33E₁The movement of the particles depends on the kinetic energy of the particles.
When kinetic energy of the particles is 100%, the particles can oscillate from x₁ to x₅.
However, when the total energy of this particles is reduced to one-third (¹/₃) or 33% of the initial energy of the particle, the oscillation of the particles will be reduced.
The maximum position the particle can oscillate is x₅The half position the particles can oscillate is x₃Since 33% is less than the half of the energy of the particle, the particle will oscillate between x₁ and x₂.
Thus, we can conclude that the particles can undergo small oscillations around x₂.

An ideal gas occupies a volume of 1cm^ atv20°c and atmospheric pressure determine the number of molecules of gas in the container
Answer:
By Charles Law the volume of 1 cm^3 at standard conditions is
V = V0 * 273 / 293 = 1 cm^3 * .932 cm^3
Reducing the temperature to 0 deg C results in a volume of .932 cm^3
1 mole of gas contains 22.4 L of gas
1 L = 1000 cm^3
1000 cm^3 / L / (.932 cm^3 / container) = 1073 containers / L
So 1 mole of gas = 1073 containers * 22.4 L /container = 24,305 L
6.02E23 molecules / mole * 1 / 24305 molecules / mole = 2.48E19
number of molecules present = 2.48 * 10^19
(Easier to calculate volume of 1 cc
1 cc = 6.02E23 / (1000 * 22.4) = 2.69E19 molecules in 1 cc
Vol of 1cc = 273 / 293 = .932
2.69E19 * .932 = 2.51 * 10^19)

For a projectile with initial velocity of 51.5 m/s and angle of elevation equal to 4 degrees.
a) Compute the horizontal velocity of the projectile in m/s.
b) Compute the vertical velocity in m/s.
c) Compute the time of flight for the projectile.
d) Compute the distance downrange.
e) Compute the maximum height reached by the projectile.
Answer:
Below
Explanation:
c) To find the time of flight of a projectile (assuming from the given information that there is no vertical displacement) you can use this formula :
t = 2(Vi) Sinx / g
t = 2(51.5m/s) Sin(4) / 9.8 m/s^2
t = 0.733 seconds
t = 0.73 seconds
d) To find the displacement in the x-direction you can use this formula :
dx = vi^2 sin(2x) / g
dx = (51.5m/s)^2 sin(2(4)) / 9.8m/s^2
dx = 37.6654 m
dx = 37.7 meters
e) To find the peak height of the projectile you can use this formula :
v^2sin^2(x) = 2gh
(51.5m/s)^2sin^2(4) = 2(9.8m/s^2)h
h = 0.658 meters
h = 0.66 meters

If you throw a ball up into the air and it reaches its original height after 6 seconds, calculate how high above its original position the ball reached. (Answer to two decimal places).
Explanation:
Assuming that there is no air resistance, the given time means that the ball reached its maximum height 3 seconds after throwing it upwards so we can solve its
maximum height by solving for [tex]v_{0y}[/tex] first:
[tex]v_y = v_{0y} - gt \Rightarrow v_{0y} = gt[/tex]
[tex]v_{0y} = (9.8\:\text{m/s}^2)(3\:\text{s}) = 29.4\:\text{m/s}[/tex]

What do you mean by an Atom?An atom may be defined as a particle of matter that uniquely defines a chemical element. Each and every atom consists of a central nucleus that holds positively charged subatomic particles known as Protons along with neutrons.
Apart from protons and neutrons, the negatively charged subatomic particles known as electrons are always revolved around the nucleus of each atom in its orbitals.
According to the context of this question, an atom is the smallest unit of matter which significantly retain all the chemical properties of an element. Thus, the second option is eliminated. They are naturally present not made in stars. So, the option third is also eliminated.

A light, inextensible cord passes over a light,
frictionless pulley
with a radius of 7.2 cm
It has a(n) 16 kg mass on the left and a(n)
6.7 kg mass on the right, both hanging freely.
Initially their center of masses are a vertical
distance 4.2 m apart.
The acceleration of gravity is 9.8 m/s^2
The question tied to it is…
What is the tension
in the cord when they
pass each other?
Answer in units of N.
Answer: T = 93 N
Explanation:
Assuming the pulley is ideal meaning frictionless as mentioned and also negligible mass.
ΣF = Σma
Mg - mg = Ma + ma
a = g(M - m) / (M + m)
Now looking only at the larger mass as it falls
Mg - T = Ma
T = Mg - Ma
T = Mg - Mg(M - m) / (M + m)
T = Mg(1 -(M - m) / (M + m))
T = 16(9.8)(1 - (16 - 6.7) / (16 + 6.7))
T = 93 N
or looking only at the smaller mass
T - mg = ma
T = m(g + a)
T = m(g + g(M - m) / (M + m))
T = mg(1 + (M - m) / (M + m))
T = 6.7(9.8)(1 + (16 - 6.7) / (16 + 6.7))
T = 93 N

A plane flying due north at 191 mph encounters winds that blow the plane due east at 45 mph. Determine the plane's resultant velocity. Record your answers to the nearest tenth.
Answer:
Below
Explanation:
For these types of questions, you should draw out your triangles and resultant vectors.
For this, we can use the pythagorean theorem to solve this :
vpf^2 = vpi^2 + vw^2
vpf^2 = 45^2 + 191^2
vpf = [tex]\sqrt{38507[/tex]
vpf = 196.2294
vpf = 200 mph
Now we need to find the angle of the plane's direction using soh cah toa
Tan(x) = O / A
x = tan^-1(191/45)
x = 76.74
x = 77 degrees
Therefore, the plane's result velocity is 200 mph [ E 77 N ]

When do you know if Respect is being shown? If there is discrimination? Cite some indicators
Peace and violence are the indicators of the society.
Respect is shown if we see a people as a person and not as a toy. If we stop criticizing and judging by just looking at them than the other person also gives us respect which leads to peace and harmony in the society.
If there is discrimination and no respect of other people's feeling then there is violence and disharmony in the society so we can conclude that peace and violence are the indicators of the society.
