ANSWER: 170 Feet
REASON: with good breaks and a dry road your car should stop and skip 170 feet, with perception and reaction time of stopping you should stop within 170 feet

Explanation:
= Heat capacity of Hg = 28 J/mol
= Change in temperature =
= Enthalpy of fusion = 2.29 kJ/mol
The number of moles is given by
Heat is given by
Heat released is given by
Total heat is given by
The total heat released is
3^3 is the way you write 3³ when you don't have any way to write the ³ .
Whichever way you write it, it means " 3 · 3 · 3 " . That's 27 .
I don't know what would be considered "simplifying" it. Maybe " 3³ "is a little simpler, but you can't always write that if your computer or your word processor doesn't give you a way to write exponents.
" 3 · 3 · 3 " certainly is not any simpler than " 3^3 ", so that's not it.
" 27 " may be simpler.
Answer:
total volume is 0.9125 m³
Explanation:
given data
oil = 28 litres
pressure p = 40 MPa
final pressure p2 = 35 MPa
initial pressure p1 = 30 MPa
y = 1,4
to find out
volume of accumulator
solution
so we here say that volume of oil
v3 - v2 = 28 litres
so v3 = 0.028 + v2 ......................a
and volume formula is
v1 = v2 ...................1
so v2 = v3 ..............2
put here value in equation 2
v2 = (0.028 + v2)
v2 = 0.274 m³
and here v1 will be
v1 = 0.274
v1 = 0.3365 m³
and v3 will be
v3 = 0.028 + v2
v3 = 0.028 + 0.274
v3 = 0.302 m³
so
total volume is v1 + v2 + v3
total volume = 0.274 + 0.3365 + 0.302
total volume is 0.9125 m³
