Answer:

Option B

Explanation:

The phenomenon of bending of light at the interface of two mediums is known as refraction. Refraction occurs when light goes from one medium to another. It bends away from normal when light passes from denser medium to rarer and bends towards the normal when light passes rarer medium to denser medium.

Any lens forms image by bending the light. A mirror forms image when light bounces off its surface that is undergoes reflection. A lens and mirror can be both concave and convex.

Thus, option B is correct.

An unnamed professor is walking to class when an office chair (travelling in the same direction) collides with them. The profess

Answer: 1.96 m/s

Explanation:

Given

Mass of Professor $m_1=113\ kg$

Velocity of professor $u_1=1.56\ m/s$

mass of chair $m_2=10\ kg$

velocity of chair $u_2=6.5\ m/s$

Suppose after the collision, v is the common velocity

Conserving momentum

$\Rightarrow m_1u_1+m_2u_2=(m_1+m_2)v\\\\\Rightarrow v=\dfrac{113\times 1.56+10\times 6.5}{113+10}=\dfrac{241.28}{123}\\\\\Rightarrow v=1.96\ m/s$

Which of the following statements correctly describes the position of the intake and exhaust valves during most of the power sta

I am Lyosha [343]

Both valves are closed during the power stroke.

While the fuel is burning in the cylinder, you want
all the force of the expanding gases to push the
piston down ... you don't want any of the gases
or their pressure escaping.

If either of the valves was open, even just a crack,
then part of the gases would go blooey out the valve,
and some pressure would be lost that's supposed to be
pushing the piston.
