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.

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.

Gravity

Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

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.

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.

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.

ACDE

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  = mass x acceleration due to gravity x height

These description satisfies options A, C

             Kinetic energy  = [tex]\frac{1}{2}[/tex] x mass x velocity²

The description satisfies DE

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.

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]

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

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.

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:

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.

"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."

"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."
