2 answers:
Answer:
D
Explanation:
Work = Mass * Gravity(9.8) * Height
height=work/(mass*9.8)
height=255/(2.5*9.8)=10.4m
Answer:
D 10.2
Explanation:
255 ÷ 2.5= 10.2 or D

then force becomes mg
that is F=Mg
=4*9.8
then by using the formula
F=Ma
a=F/M
=4*9.8/9.8
=4

Answer:
The answer to your question is: V2 = 1 l
Explanation:
Data
P1 = 200 kPa
P2 = 300 kPa
V1 = 1.5 l
V2 = ?
Formula
P1V1 = P2V2
V2 = (P1V1) / P2
V2 = (200 x 1.5) / 300
V2 = 1 l
