A light ray bounces off a fish in your aquarium. It travels

frutty [35]

Answer:

Correct

Explanation:

Because the light can't travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water. Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.

A student wants to use a ramp to move boxes into a truck bed that is 3 m high. He has a choice of 2 different ramps. The length

pishuonlain [190]

Answer:

the ramp with 6 m length will be easier to work with.

Explanation:

the mechanical advantage of the ramp can be calculated to find out which ramp will be easier to work with. The ramp with greater mechanical advantage will be easier to work with. The formula for the mechanical advantage of ramp is given as follows:

$M.A = \frac{L}{h} \\\\$

where,

M.A = Mechanical Advantage = ?

L = Length of Ramp

h = height of ramp = 3 m

FOR L =4 m:

$M.A = \frac{4\ m}{3\ m}\\\\M.A = 1.33$

FOR L = 6 m:

$M.A = \frac{6\ m}{3\ m}\\\\M.A = 2$

Since, the ramp with length 6 m has a greater mechanical advantage.

Therefore, the ramp with 6 m length will be easier to work with.
