hope this helped : )
Answer:
291 K is the answer
Explanation:
to get Kelvin from Celsius use the following
Kelvin = Celsius +273
= 18 +273
= 291
The problem is fairly simple if you use the formula.
Formula: Force = (mass) x (acceleration)
3 x 5 = 15 newtons
Note: 3 kg is the mass of the skateboard, and 5 m/s2 is the acceleration.
Answer: 15 newtons
It would mean that you could not know the precise volume of the sand. Only the volume of the sand plus the water that was making it damp.
In the experiments listed, the effects are easy to deduce by understanding that the water in the sand adds volume to the 'sample' being measured.
So in the case of calculating air space you would calculate <em>less</em> air space.
