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.

Answers

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."

Is a violin and battery potential energy?

Answers

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.

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

Answers

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.

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.

Answers

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 :

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

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 medium

These description satisfies options A, C

Kinetic energy is the energy due to the motion of body. It is mathematically given as:

Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss

Answers

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.

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.
