expalin how waves energy and matter are related

Answer:

The required elastic potential energy is 0.068J

Explanation:

Given,

Spring force constant, k= 3.4 N/M

Spring stretch length/ Displacement, x= 0.2m

We know,

Elastic potential energy, V= [tex]\frac{1}{2} kx^{2}[/tex]

                                           =[tex]\frac{1}{2}*3.4*(0.2)^{2}[/tex]

                                           =[tex]\frac{0.136}{2}[/tex]

                                           =0.068

∴The required elastic potential energy is 0.068J

Answer:

[tex]d=1.8\ g/cm^3[/tex]

Explanation:

Given that,

Mass, m = 27 grams

Volume of the substance, V = 15 cm³

We need to find the density of the substance. We know that, the density of an object is given by mass per unit volume. So,

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{27}{15}\\\\d=1.8\ g/cm^3[/tex]

So, the density of the substance is equal to [tex]1.8\ g/cm^3[/tex].

Answer: I think a

Explanation:

Answer:

On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

I = 4 A

Explanation:

From Ohm's law, the voltage is given by

V = IR

or

I = V/R = (80 V)/(20 ohms)

= 4 A

Answer:

the charges get closer together

Answer:

[tex]K=58.8N/m[/tex]

Explanation:

From the question we are told that:

Mass [tex]M=0.442[/tex]

Drop distance [tex]d=0.150[/tex]

Generally the equation for Spring Constant is mathematically given by

 [tex]K=\frac{2mg}{x}[/tex]

 [tex]K=\frac{2*0.442*9.8}{1.150}[/tex]

 [tex]K=58.8N/m[/tex]

The Andromeda is a galaxy which is nearest to the milky way. It is also named as Messier 31 or M31 or NGC 224. It is a spiral galaxy located at a distance of approximately 2.5 million light years from earth.

another name Andromeda in Hindi is Vaikunth.

Explanation:

The Andromeda Galaxy (IPA: /ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way.

Answer:

output force is exerted in the machine , i guess

Answer:

false

Explanation:

Answer:

true

Explanation:

Space is not a medium. and we can not her anything in space. therefore you need a medium in order to hear sound waves.

Answer:

yes because there is also a theory about this I studied in biology

theory name -Lamarck's theory

Answer :— Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Hope you understand :)

Answer:

Explanation:

Kinetic energy (K.E)=1/2*mass*velocity^2

The fomula to calculate resistance is:

voltage/cutrent

9 V/3 A= 3 ohms

Answer:

8

Explanation:

Square root means what two same numbers multiplied together equal the same number,

So:

Answer:

Thus, the horizontal range is 17.7 m, and the maximum height is 10.2 m.

Explanation:

velocity of projection, v = 20 m/s

Angle of projection, A = 30 degree

The horizontal range is

[tex]R =\frac{v^{2}sin2A}{g}\\R=\frac{20\times 20\times sin60}{2\times 9.8}\\R=17.7 m[/tex]

The maximum height is

[tex]H =\frac{v^{2}sin^{2}A}{2g}\\H=\frac{20\times 20\times sin^{2}30}{9.8}\\H=10.2 m[/tex]

Answer:

a) "gravitation" is the force causing you to go down a waterslide

b) It is "fluid friction" as a solid object (our body) moves over a fluid (the water)

c) It would become "sliding friction" since two solid surfaces slide over each other

d) fluid friction being the weakest friction, switching to sliding friction means a higher decrease in speed and therefore removing the water from a slide will decrease our speed

Answer:

The rate of change in position of an object with respect to time, and displacement is called velocity.

Answer:

Explanation:

Centripetal acceleration's equation is:

[tex]a_c=\frac{v^2}{r}[/tex] where v is the velocity of the object (moon II) and r is the radius. We have the radius, but we don't have the velocity, and we can't solve for acceleration until we do have it. Assuming moon II is a circle, or close enough to be called a circle, it has a circumference.

C = 2πr. If we can find the circumference of the circle, we can plug in the orbital period for the time, the circumference for the distance, and solve for velocity in d = rt. So let's do that and see what happens.

C = 2(3.14)(9.0 × 10⁷) and

C = d = 5.7 × 10⁸. Plugging in and solving for v:

[tex]5.7*10^8=v(3.0*10^5)[/tex] and

v = 1.9 × 10³. That is the velocity we can use in the centripetal acceleration equation.

[tex]a_c=\frac{(1.9*10^3)^2}{9.0*10^7}[/tex] and

[tex]a_c=.040\frac{m}{s^2}[/tex]

These are fun!

Explanation:

When something is moving, we call it is in motion. It can be also defined as a change of position in relation to another object.

When an object is not moving at all, we call that it was at rest.

To be in motion, there must be a change in position.

Hence, the correct options are "a change of position in relation to another object" and "something is moving".

HOPE IT HELPS YOU!!

Answer:

7. (C) 12 m/s

8. (D) 44.1 m

9. (C) 9.8 m/s^2

Explanation:

8. y = -(1/2)gt^2

= -(1/2)(9.8 m/s^2)(3 s)^2

= -44.1 m

This means the ball traveled 44.1 vertically downwards.
