Apply Boyle's law:
PV = const.
P = pressure, V = volume, the product of P and V must stay constant
Our initial P and V values are:
P = 0.52atm, V = 5.7L
Our final P and V values are:
P = ?, V = 2.0L
Set the products of each set of PV values equal to each other and solve for the final P:
P(2.0) = 0.52(5.7)
P = 1.48atm
Answer:
It will apply the greatest pressure of an area of 1.
Explanation:
To find pressure use the formula P = F/A
P = 100/1
P = 100
Answer:
-929.5Joules
Explanation:
To get the work done by sam, we will calculate the kinetic energy of sam expressed as;
KE = 1/2mv²
m is the mass = 1100kg
v is the velocity = 1.3m/s
KE = 1/2(1100)(1.3)²
KE = 550(1.69)
KE = 929.5Joules
Since Sam is opposing the direction of movement, work done by him will be a negative work i.e -929.5Joules
