expalin how waves energy and matter are related

Answers

Answer 1
They are related because waves affect matter. Reflection, refraction, and diffraction. Reflection occurs when wave bounces back from a surface that they cannot pass through. Refraction occurs when waves bend as they enter a new medium at an angle and start traveling at a different speed.

11. (a)What downward force is acting on you when you go down a waterslide? (b)What type of friction is
present? (c)If the waterslide were dry explain what type of friction in would be and (d)how that
changes your speed? (4 points)

Answers

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

Motion is
displacement
a change of position in relation to another object
an object you look at to determine if something is moving
speed

Answers

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".

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

A spring is hung from the ceiling. A 0.442-kg block is then attached to the free end of the spring. When released from rest, the block drops 0.150 m before momentarily coming to rest, after which it moves back upward. (a) What is the spring constant of the spring

Answers

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]

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]

What is kinetic energy formula???​

Answers

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.

0.024 m/s2
0.081 m/s2
0.040 m/s2
0 0.19 m/s2

Answers

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!

the volume and the mass of substance are 15cm3 and 27 gm respectively find its density​

Answers

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].

What is the difference between Mass and Weight?

Why do we use mass instead of weight?

Answers

Mass is a measure of how much force it will take to change that path. ... Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object. This force increases with the object's mass: the more inertia it has, the harder gravity pulls.
In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.

what is force of gravity​

Answers

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.
