When we stretch a spring, which two factors affect how much elastic
potential energy is stored in it
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.
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

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]

Answer:
c - the frequency of the waves decreases
what would the answer be
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 2 cm object is 10 cm from a convex lens that has a focal length of 4.4 cm. The image is 8 cm from the lens.
The height of the image, to the tenths place, is
cm.
Answer:
-1.6
Explanation:
e2021
The Height of an Image for a Convex Mirror is calculated by using magnification equation
m = h(i) / h(o) = − d(i) / d(o) ,where
the magnification index of the mirror, m
the height of the object, h(o)
the height of the image, h(i)
the distance between the object and the mirror, d(o)
the distance between the image and the mirror, d(i)
h(i)/ 2 = -8 / 10
h(i) = -1.6 cm.
What is convex mirror ?"Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. This bulging out surface reflect light outwards and are not used to focus light."
What is magnification equation ?"The formula for magnification is m=h(i)/h(o)=-d(i)/d(o). m is the total magnification; h(i) is the height of the image; h(o) is the height of an object; d(i) is the distance from the lens to the in focus projected image; d(o) is the distance of the object to the lens. The negative sign represents that the image is inverted."

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

Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss
Answer:
190 kg m/s
Explanation:
Momentum = Velocity × Mass
→ Substitute in values
2 × 95 = 190 kg m/s
The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.
What is Momentum?Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -
p = mv
It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.
Given is a boat with a mass of 95 Kg moving at 2 m/s.
Mass [m] = 95 Kg
Velocity [v] = 2m/s
We can write the momentum as -
p = mv
Substituting values, we get -
Momentum [p] = 95 x 2 = 190 Kg m/s
p = 190 Kg m/s
Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

a girl pushes her little brother down a snowy hill on a sled and he rides quickly to the bottom of the hill
which one of Newton's Laws is this
Answer:
Newton's First Law of Motion.
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's First Law of Motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
In this scenario, a girl pushes her little brother down a snowy hill on a sled and he rides quickly to the bottom of the hill. The push from the little boy's sister is the external force acting on him and consequently, causing him to be in motion down the snowy hill.

Explanation:
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
Also, kinetic energy is directly proportional to the velocity of a body.The description satisfies DE
