I'm afraid you're not paying attention. This question is loaded with
all the important words, and you don't recognize Newton's second
law of motion. Didn't you notice the "force", "acceleration", and
"mass" all over the place in there ?
Newton's 2nd law: Force = (mass) x (acceleration)
The answer is going to be 'mass', so let's divide
each side of Newton's law by 'acceleration':
Mass = (force) / (acceleration)
Now, just write in the numbers that the question gave you:
force = 60 newtons
acceleration = 4 m/s²
Here's the equation again: Mass = (force) / (acceleration)
= (60 N) / (4 m/s²)
= 15 kg .
Answer:
the ans is D... good luck
<span>C. A concave lens can only form a virtual image, because they are thinner in the middle and thicker around the edges.</span>
Answer:
Let M1 = 8 kg and M2 = 34 kg
F = M a = (M1 + M2) a
F = M2 g the net force accelerating the system
M2 g = (M1 + M2) a
a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2
Although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.
<h3>What is the transmission spectrum?</h3>
The transmission spectrum indicates the light portion having a given wavelength that can be passed through a filter.
This spectrum (transmission spectrum) depends on the physical separation of the particles that form the filter.
In conclusion, although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.
