Answer: 1.50
Explanation:
Given that:
C (critical angle) = 41.7°
n (index of refraction in benzene) = 2.42
n (index of refraction in benzene) = ?
To get the index of refraction in benzene, Apply the formula n = 1/sineC,
n = 1/sine41.7°
n = 1/sine 41.7°
n = (1/0.6652)
n = 1.50
Thus, the index of refraction for the ray in benzene is 1.50
Answer : The rocks and debris would never accrete into a planet.
Explanation : Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force the rocks and debris would not come together to form a clump.
So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.
Answer: equal to one
Explanation:
Because is the sum of the relative frequencies.
Answer:
4
Explanation:
Given parameters:
Force input = 30N
Force output = 120N
Unknown:
Mechanical advantage of the lever = ?
Solution:
The mechanical advantage is the quantity that describes how much a simple machine is able to multiply force.
This is expressed as:
Mechanical advantage = Force output / Force input
Mechanical advantage = = 4
