When light passes through one transparent medium to another transperent medium it bends and that beding of light is know as refraction of light !

Answer:

t = 8.94 s

Explanation:

We will use the second equation of motion to calculate the time taken by the cart:

[tex]s = v_it + \frac{1}{2} at^2[/tex]

where,

s = distance = 200 m

vi = initial speed = 0 m/s

t = time taken = ?

a = acceleration = 5 m/s²

Therefore,

[tex]200\ m = (0\ m/s)(t)+\frac{1}{2}(5\ m/s^2)t^2\\\\t^2 = \frac{(200\ m)(2)}{5\ m/s^2}\\\\t = \sqrt{80\ s^s}[/tex]

t = 8.94 s

Answer:

Snell's law of refraction also known as the second law of refraction which states:

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant or given pair of Media .

Answer: "People will say the length of a day is determined by just the rotation rate of a planet, but that isn’t entirely true. The orbit around its sun also factors in. What we define as a day is the time between when the Sun is highest in the sky until the next time the Sun is at the highest point in the sky. This isn’t just the time it takes the Earth to rotate once on its axis, though. This is because, as the Earth is rotating, it’s also moving relative to the Sun"

Here, the hydrogen atoms are combined to form a helium atom, and during this process of fusion, a significantly large amount of energy is released. Thus, stars produce a large amount of energy by forming helium from the combination of hydrogen in its core. Hence, the correct answer is option (C).

Answer:

A. Creating helium from hydrogen in its core.

Explanation:

Explanation:

antimatter - counterpart of ordinary matter; identical in every way except for charge. Examples are positrons (counter to electrons) and antiprotons (counter to protons). Direct contact between matter and antimatter results in total annihilation accompanied by huge radiation output.

dark matter - hypothesized as the non-visible or not directly observable kind of matter that could explain some of the unusual behavior of stars and galaxies.

dark energy - hypothesized to be some kind of a repulsive force like anti-gravity that could explain the apparent accelerated rate of expansion of the universe.

degenerate matter - a very dense form of matter made up of fermions (like protons and neutrons) only. Some stars are believed to be made of degenerate matter.

Answer:

Yes. Although the names sound vague and almost fictional, the types of matter called antimatter, dark matter, dark energy, and degenerate matter are all different, specific entities that really exist in our universe. ... Antimatter is just regular matter with a few properties flipped, such as the electric charge.

Answer:

Explanation:

edge

C) South

As we know that, north is considered as negative, and south as positive. Now, the charge on particle is negative; so, when we will release it, it will move towards the south.

In the scenario where the negatively charged particle is placed in a uniform electric field, the direction will be C. South.

It should be noted that an electric field simply means the physical field which surrounds electrically charged particles.

Since the negatively charged particle is placed in a uniform electric field directed from South to North, the direction that the particle move after it is released is South.

Answer:

1) a ray parallel to the optical axis that after passing through the lens passes through the focal length

2) a ray that passes through the center of curvature, this ray does not have any deviation

real image   d_{objet} > f

Explanation:

In geometric optics, you can find the position of the image by geometric method, we draw two rays

1) a ray parallel to the optical axis that after passing through the lens passes through the focal length

2) a ray that passes through the center of curvature, this ray does not have any deviation

3) a ray that passes through the focal length and when passing the lens comes out horizontally

The interceptor point is where the image is

To determine if the image is real or virtual, when the object is at a greater distance than the focal length, the image is real and when it is at a shorter distance, the image is virtual.

The virtual image is formed on the same side as the object

real image   d_{objet} > f

Answer:

Sound is transmitted by longitudinal waves thru air - the observer cannot hear the explosion because no air is present between the moon and the ship

Light is transmitted by electromagnetic waves so the light from the explosion can travel between the  moon and the observer.

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:

in orbit

Explanation:

An object in orbit, like an object falling to the ground, is pulled toward Earth's center. If the object moves far enough forward as it falls, it orbits around Earth instead of hitting the ground.

Answer:

Explanation:

A body is said to be in uniform acceleration if change in velocity with respect to time is the same in equal time interval .

A body is said to be in non uniform acceleration if change in velocity with respect to time is not the same in equal time interval.

Answer: [tex]10.42\ m/s[/tex]

Explanation:

Given

Usain Bolt ran the race with a length [tex]200\ m[/tex]

Time is taken to complete it [tex]t=19.19\ s[/tex]

We know, [tex]\text{Distance}=\text{speed}\times \text{time}[/tex]

Insert the values

[tex]\Rightarrow 200=v\times 19.19\\\\\Rightarrow v=\dfrac{200}{19.19}\\\\\Rightarrow v=10.42\ m/s[/tex]

So, the speed of Usain Bolt is [tex]10.42\ m/s[/tex]

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration.An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down.

Answer:

Answer

When decrease in velocity is called negative acceleration

Answer:

B - Person A's chair rolls backwards.

Explanation:

This can be seen simply through the Conservation of Momentum. When the ball is thrown to be, the ball's momentum(+m) is transfererd to B, so B's chair moves forward(think about it - it makes sense, doesn't it?), meaning A's chair moves backwards.

So, B.

Answer:

 a = 10 ρ_air g [tex]\frac{\Delta P}{m P_o}[/tex]

Explanation:

Let's solve this problem in parts, with the initial data the camera rises slowly, so we can assume that at constant speed, we apply the equilibrium condition

         B - W = 0

The thrust is given by Archimedes' law

         B = rho_aire g V_body

The volume of the body can be found from the ideal gas ratio

         P V = n R T

let's use the subscript "o" for the initial concisions

         V₀ = (nR) T₀/P₀               1

we substitute

          10 ρ_air g (nR) T₀ /P₀ = W

when the storm approaches the pressure decreases, P

If we use the ideal gas equation

           V = (nR) T₀ / P

we combine this equation with equation 1

            V = V₀P₀ / P

if we write the pressure

             P = P₀ -ΔP

we substitute

            V = [tex]\frac{V_oP_o}{P_o - \Delta P} =V_o \ ( 1 - \frac{\Delta P}{P_o} )^{-1}[/tex]

we expand serie  and eliminate higher order terms

            V = V₀ ([tex]1+ \frac{\Delta P}{Po}[/tex])

with this expression we can write the thrust

             B = B₀ + ΔB

Newton's second law for the new conditions is

             B - W = m a

             (B₀ + ΔB) - W = ma

              ΔB = m a

              a = ΔB / m

              a = 10 ρ_air g [tex]\frac{\Delta P}{m P_o}[/tex]

This is the initial acceleration of the camera
