Do not forget that mass = <span>volume x density
</span>Mass of 1 cm^3 = Density[/tex]

Then eventually we can find <span>mass of 5 cm^3 : =
</span>

So the answer is D
<span>And that's it. I'm sure it will help.</span>
Whenever we move, we alter the rate at which we move into the future. This statement is true.
Answer:
decreases
Explanation:
Remeber:
There is always inverse relation between frequency and wavelength.
So if one of them increases, other decreases and vice-versa.
f ∝ 1 / λ
Answer:
23 m/s downward
__________________________________________________________
<em>Taking the downward direction as positive</em>
<u>We are given:</u>
Initial velocity of the marble (u) = 0 m/s
Time interval (t) = 2.3 seconds
Final velocity (v) = x m/s
<u>Solving for the Final velocity:</u>
<u>Acceleration of the Marble:</u>
We know that gravity will make the marble accelerate at a constant acceleration of 10 m/s
<u>Final velocity:</u>
v = u + at [First equation of motion]
x = 0 + (10)(2.3) [replacing the given values]
x = 23 m/s
Hence, after 2.3 seconds, the marble will move at a velocity of 23 m/s in the downward direction
