Momentum = mass x acceleration
5 x 2 = 10 kg. m/s
Answer:
Explanation:
The density of the solid is
we want to convert it into kg/m^3. We must note that:
Therefore, the conversion can be done as follows:
Answer:
346819 Pa or ,347000 Pa in 3 significant figures
Explanation:
P1= 325000Pa , T1= 283K ,
P2=? T1= 302 K
as here volume and mass both are constant so using ratio method for pressure temperature law we have P1/T1 = P2/T2
THIS WE CAN ALSO OBTAIN BY RATIO METHOD FOR GENERAL GAS LAW AS
P1V1/(m1T1 ) = P2 V2/ (m2 T2)
IF V1 = V2 =V AND m1=m2=m then expression reduces to
P1/T1 = P2/T2
or P2 = (P1/T1)×T2
P2 = (325000/283) × 302
P2 = 1148.41×302
P2=346819
P2 = 347000 Pa in 3 significant figures
It's the instantaneous speed. Average speed would take all the different speeds from the whole ride in order to fine the median or middle speed.
It Increases. I just took a quiz with the same question.
