Answer:
When white light shines on the bubble, it acts as a prism. While some of the white light bounces back off, some of them pass through the prism forming fringes of colors. But then, they too bounce off the inner part of the film. So one set of light rays shine into a soap bubble, but two sets of rays come back out again. When they emerge, the waves that bounce off the inner film have traveled a tiny bit further than the waves that bounced off the outer film. So, we have two sets of light waves. After that, the waves starts merging (Just like the ripples in the pond) . Some add together while some cancel out. That is why we see the pattern of colors repeating in the thin film soap.
IF voltage remains constant, then current is
inversely proportional to resistance.
The correct response is "b).", signifying "false" as the choice.
Answer:
the force acting on the team mate is 1.19 kN.
Explanation:
given,
mass = 196 lbm
while tackling, the deceleration is from velocity 6.7 m/s to 0 m/s
time taken for deceleration = 0.5 sec
F = mass × acceleration
acceleration = 
= -13.4 m/s²
1 lbs = 0.453 kg
196 lbs = 196 × 0.453 = 88.79 kg
F = 88.79 × 13.4
F = 1189.786 N = 1.19 kN
hence, the force acting on the team mate is 1.19 kN.
The volume of the sample is 48.39 cm³.
<h3 /><h3>What is volume?</h3>
The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface
To calculate the volume of the sample, we use the formula below
Formula:
- D = m/v
- v = m/D................ Equation 1
Where:
- m = Mass of the smaple
- D = Density of the sample
- v = Volume of the sample.
From the question,
Given:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.
