What force causes Earth's centripetal motion?

Physics
2 answers:
Savatey [412]4 years ago

Answer:

gravity

Explanation:

Earth Motion in Centripetal direction is due to the centripetal force on the Earth.

As we know that Earth revolves around the sun with the force on Earth due to the Sun towards it.

If we assume the motion of Earth to be circular motion around the Sun then the force due to which Earth maintains its circular trajectory is known as Centripetal force.

Here this centripetal force is the gravitational force of Sun towards it

So correct answer would be

GRAVITY

A red laser from a physics lab is marked as producing 632.8 nm light. When light from this laser falls on two closely spaced sli
goblinko [34]

Given Information:  

Wavelength of the red laser = λr = 632.8 nm

Distance between bright fringes due to red laser = yr = 5 mm

Distance between bright fringes due to laser pointer = yp = 5.14 mm

Required Information:  

Wavelength of the laser pointer = λp = ?

Answer:

Wavelength of the laser pointer = λp = ?

Explanation:

The wavelength of the monochromatic light can be found using young's double slits formula,

y = Dλ/d  

y/λ = D/d

Where

λ is the wavelength

y is the distance between bright fringes.

d is the double slit separation distance

D is the distance from the slits to the screen

For the red laser,

yr/λr = D/d

For the laser pointer,

yp/λp = D/d

Equating both equations yields,

yr/λr = yp/λp

Re-arrange for λp

λp = yp*λr/yr

λp =  (5*632.8)/5.14

λp = 615.56 nm

Therefore, the wavelength of the small laser pointer is 615.56 nm.

Which statement accurately describes the motion of the objects in the ticker tape above?
Fynjy0 [20]

Answer: "One object speeds up before it slows to a stop "

(the top one)

Explanation:

Ok, first a little recall on how to read this type of graph.

If the points are far apart, the object is moving fast.

If the points are close together, the object is moving slow.

If the distance between the points changes then the velocity of the object changes, which means that the object is accelerated.

If we have a lot of points clustered in one location, then the object is not moving.

We can see:

The top object starts slow, then it increments the speed, then it slows down again, and then it comes to stop.

The bottom object starts fast, and it slows down.

then:

"One object speeds up before it slows to a stop "

This describes the motion of the top object, this is the only correct option that describes one of the graphs.

a surface recieving sound is moved from it original position to a position three times farther away from the source of the sound
Delicious77 [7]
Sound intensity = 1/(r^2)

That is Sound intensity is indirectly proportional to  the distance. Therefore, sound becomes 9 times less intense.
