Answer:
5 and 3/4 meters
Explanation:
This is because if it is slowing down by 4 meters and it was moving at 23, then you would figure out how many times 4 can go into 23 and you'd get 5 and 3/4 meters.

Is gravitational energy a form of kinetic energy or potential energy? Why do you think that?
Please help due today!!
Answer:
When something is lifted, work is done on the object against the pull of gravity. This work is converted to a form of potential energy called gravitational potential energy. When the item falls towards Earth like an apple from a tree, gravitational potential energy is converted into kinetic energy.

infrared light<<<----- CORRECT
visible light
Explanation:
Edge 2021
Infrared light is typically used to make images based on the temperatures of objects.
What is meant by electromagnetic spectrum?The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).
Here,
Similar to visible light, X-rays are a type of electromagnetic radiation. X-rays have a higher energy than light, on the other hand, and can penetrate most materials, including the human body.
Images of inside body tissues and structures are produced using medical x-rays.
Electromagnetic energy in the infrared region of the spectrum can be seen by them. There is a relationship between an object's temperature and the electromagnetic radiation it releases since infrared radiation is strongly related to object temperature.
Hence,
Infrared light is typically used to make images based on the temperatures of objects.

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:

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.

Find the electric field E⃗ (r⃗ )E→(r→)E_vec(r_vec) inside the sphere (for rrr< aaa) in terms of the position vector r⃗ r→r_vec. Express your answer in terms of r⃗ r→r_vec, rhorhorho (Greek letter rho), and ϵ0ϵ0epsilon_0.
Solution :
Using the Gauss law, the electric field intensity of a sphere is given by :
[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]
[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]
Now the enclosed charge inside the sphere (r<a) is
[tex]$Q_{enc}= \rho V$[/tex]
[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]
Hence, the electric field intensity becomes as follows :
[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]
[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]
Thus, the electric field inside the sphere is given by :
[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]
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
The time for a sound wave to travel between two people is 0.80 s,
The people are 256 m apart
Calculate the speed of sound in air.
Answer:
Explanation:
Using the below formula
Speed of sound = ( distance between observers) *2/(total time taken)
Now putt the given values ,
time taken = 0.80 sec
distance = 256 m
hence
V of sound= 256*2/0.80
V of sound = 640 m/sec
how much energy must be absorbed by water with a mass of 0.5kg in order to raise the tempature from 30c to 65c
Answer:
62760J
Explanation:
Given parameters:
Mass = 0.5kg = 500g
Initial temperature = 30°C
Final temperature = 65°C
Unknown:
How much energy is absorbed by the water = ?
Solution:
To solve this problem, we use the expression below:
H = m C Δt
H = m x C x (t₂ - t₁ )
m is the mass
C is the specific heat = 4.184J/g°C
t₂ is the final temperature
t₁ is the initial temperature
So;
H = 500 x 4.184 x (65 - 30) = 62760J
Which equation should be used to calculate the speed of a wave?
speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is the formula for wave speed?The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is Speed of wave?Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.
The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.
This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.
Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

Explanation:
A spring has a constant of 875 N/m. and the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.
What is Spring constant?The spring constant is a characteristic of a spring which is defined as the ratio of the force affecting the spring to the displacement which is caused by that force. The SI unit of spring constant is N.m⁻¹ (Newton per meter).
The spring constant is:
F = -k/ x
where, k is the spring constant
F denotes the force,
and x denotes the change in the length of the spring.
k = 875N/m
x = 4.5m
We know that
Kx = mg
m= kx/ g
m = 875 × 4.5/ 9.8
m = 401.78kg
Therefore, the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.

Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.
Other energy forms stems from these two energy types.
Potential energy expressly deals with the position of a body. It is mathematically given as:Potential energy = mass x acceleration due to gravity x height
It is the energy stored based on the position of particles within a mediumThese description satisfies options A, C
Kinetic energy is the energy due to the motion of body. It is mathematically given as:Kinetic energy = [tex]\frac{1}{2}[/tex] x mass x velocity²

The unit for momentum can be Newton-second (Ns). In the CGS system, if the mass is in grams and the velocity in centimeters per second, then the unit of momentum will be gram-centimeters per second (g⋅cm/s).
What is momentum ?"Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton's laws of motion."

14. Potential:
Answer:
11. A door accelerating when pushing it.
12. A person sliding along the floor.
13. Water dropping from the faucet.
14. Courtains descending when loosening them.
Explanation:
For kinetic energy, any example that does not move horizontally will do. Something accelerating or decelerating is a good example (Ek=1/2mv^2, where v is velocity).
For potential energy try to think of things moving vertically. Potential energy comes from the height of an object (Ep=mgh, where h is height).
Notice that example 13 and 14 represent potential energy turning into kinetic energy, height becomes lower, so velocity increases.
