Answer:
<h3>5 meter / sec.</h3><h3 />
Explanation:
speed = distance / time
= 15 meters / 3 seconds
= 5 meter / sec.
Figure 1, because it is a compound.
Answer:
The thickness of the oil film is 198 nm.
Explanation:
Given that,
Refractive index of glass plate = 1.60
Refractive index of oil = 1.29
Wavelength = 511 nm
We need to calculate the thickness of the oil film
Using formula of path difference
Where, n = refractive index
t = thickness
= wavelength
Put the value into the formula
Hence, The thickness of the oil film is 198 nm.
The formula for momentum is p=mv (mass multiplied by velocity), so in this problem, p=50(.5)=25=p or in other words, momentum.
Answer:
A . Are the masses repelling or attracting
answer:
<em><u>So, positive energy densities ("masses") attract each other by gravitational interaction. This is the general idea.</u></em>
<em><u>B</u></em>. What is the magnitude of the electrical force between the objects<em><u>?</u></em>
<em><u>answer</u></em><em><u>:</u></em>
<em><u> </u></em><em><u>The magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.</u></em>
C. What would the magnitude of the force be if one of the charges was 1/3 the amount?
answer:
<em><u>0.45</u></em>
D. ) What would the force be if the distance between the charges was only 1 meter (with the original charges)?
answer;
<em><u>Fmin=2.3×10^−28</u></em><em><u>N</u></em>
<em><u>E</u></em><em><u>:</u></em><em><u> </u></em>What would the force be if one of the charges was 1/3 the amount AND the distance was 1 meter?
answer;
<em><u>Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater.</u></em>
