show the relation between degree Celsius and degree fahrenheit??​

Answer:

13. (A) 20°

14. (D) 65°

15. (A) 0 m/s

Answer:

the charges get closer together

Answer:

5.83

Explanation:

Divide the distance by velocity

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]

Answer:

8

Explanation:

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

So:

8 × 8 = 64

Answer :light

Explanation:  

A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.

Answer:

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

theory name -Lamarck's theory

yeah i did, hope you understand

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:

0.49m

Explanation:

So you need to change the original equation for finding fields to find distance, and then just plug in the numbers

Which equals 0.49meters

Also it was right on Acellus :)

Hope this helps

Answer:

A). Increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object.

Explanation:

The two objects possessing opposite or unlike charges attract one another due to the electromagnetic force between the electrons, as well as, protons in order to develop ionic lattices.

As per the question, the objects having unlike charges would attract one another more when we 'escalate the positive charge of the object having a positive charge and enhance the negative charge of the object possessing negative charge.' This will lead the atoms that are losing electrons to be positively(+ve) charged and the atoms gaining electrons to be negatively

(-ve) charged. Thus, the electromagnetic force among them increases and a stronger ionic network develops leading them to attract each other more. Hence, option A is the correct answer.

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.

Answer:

amount of charge on the source charge

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".

Answer:

21.582 Newtons

Explanation:

The weight of an object on Earth is equal to W=9.81M where M is the mass of the object and the acceleration due to gravity is 9.81 m/s^2. Therefore, the weight of the book on the earth is W=9.81(2.2)=21.582N, or 21.582 Newtons

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].

That depends upon several factors

Answer:

When object falls freely we can say

its initial speed will be ZERO

and its acceleration due to gravity must be

a = g = 9.8 m/s^2a=g=9.8m/s2

Now we need to find the distance of free fall in 3 s of time

So here we will use kinematics

y = v* t + \frac{1}{2} at^2y=v∗t+21at2

now we will plug in all values in it

y = 0 + \frac{1}{2}* 9.8 * 3^2y=0+21∗9.8∗32

y = 44.1 my=44.1m

So it will fall by total distance of 44.1 m

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!

Answer:

rolling friction is the lady in the forest

static friction is the man pushing the fridge

sliding friction is the snow kid

and fluid fraction is the bird I'm pretty sure

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
