Answer:
10.028%
Explanation:
= Angle between polarizer
The polarized light after passing through first polarizer
The polarized light after passing through second polarizer
The polarized light after passing through third polarizer
The percent of the light gets through this combination of filters is 10.028%
Answer:
88.89 cm/s or 0.89 m/s.
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 cm/s
Distance travelled (s) = 120 cm
Time (t) = 2.7 s
Final velocity (v) =.?
The final velocity of the marble can be obtained as follow:
s = ½(v + u)t
120 = ½ × (v + 0) × 2.7
120 = (v + 0) × 1.35
120 = 1.35v + 0
120 = 1.35v
Divide both side by 1.35
v = 120/1.35
v = 88.89 cm/s
We may want to express the velocity in m/s. This can be obtained as follow:
100 cm/s = 1 m/s
Therefore,
88.89 cm/s = 88.89 cm/s × 1 m/s /100 cm/s
88.89 cm/s = 0.8889 m/s
88.89 cm/s = 0.89 m/s
Thus, the marble's final velocity is 88.89 cm/s or 0.89 m/s
The answer to this question is true
The statement which best explains why nickel will reach the ground first is: C. The force of air resistance acts more strongly on the sheet of paper than on the nickel.
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of objects and the planets such as Earth around the Sun.
<h3>The factors that affect gravity.</h3>
Some of the factors that affect the force of gravitational attraction that is acting on an object or a physical body include the following:
Generally, nickel will reach the ground first before a sheet of paper due to the effect of the force of air resistance because it would act more strongly on the sheet of paper than on the nickel.
