Answer:

D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.

Explanation:

As per ray diagram we can see that light ray moves from one medium to another medium

So this must be the phenomenon of refraction of light

Now in this phenomenon of light we can see that initially light makes small angle with the normal

After moving into the other medium the light makes more angle with the normal

so here light is bending away from the normal when it is moving into the other medium

So here light is moving into less denser medium from denser medium

So correct answer must be

D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.

What is static friction?​
givi [52]

Answer:

Plzzzzzzzzzzzzzzzz brainliest

Explanation:

In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. ... The frictional force itself is directed oppositely to the motion of the object.

You push a 1.30 kg physics book 2.80 m along a horizontal tabletop with a horizontal push of 1.55 N while the opposing force of
Rzqust [24]

Answer:

<h2>3.36J</h2>

Explanation:

Step one:

given data

mass m= 1.3kg

distance moved s= 2.8m

opposing frictional force= 0.34N

assume g= 9.81m/s^2

we know that work done= force *distance moved

1. work done to push the book= 1.55*2.8=4.34J

2. Work against friction = force of friction x distance

                                       = 0.34*2.8=0.952J

Step two:

the work done on the book is the net work, which is

Network done= work done to push the book- Work against friction

Network done= 4.32-0.952=3.36J

<u>Therefore the work of the 1.55N 3.36J</u>

Temperature is a measure of how much the atoms in a substance are moving. Why is a substance hotter in the gas state than in the
dolphi86 [110]
Hey there!
In a gas state, particles have lots of energy, so they move around very rapidly, hitting each other and flowing around, that's why you see them moving so freely. Because they have so much energy, the substance is likely to be harder, as it can obtain more thermal energy, or heat.
Hope this helps!
