P=250 kg*m/s
Mass times velocity gives you momentum 25*10=250
The <u>direction</u> of force will determine the <u>direction</u> of acceleration.
Answer:
Explanation:
From the given information:
At state 1:
Initial Quality
mass = 10.0 kg
At state 2:
Temperature
mass of the piston
area of the piston
Atmospheric pressure
Gravitational acceleration = 9.81 m/s²
, This is because there exists no restriction to the movement of the piston and provided the process is frictionless. So, the process 1-2 is regarded as constant.
To calculate the applying force balance over the piston by using force balance in the vertical direction:
∴
(100 × 10³)×0.005 + 204 × 9.31 = P × 0.05
P = 500248 Pa
P = 500.25 kPa
At state 1:
Hence, this is a saturated mixture of liquid and vapor
Using the steam tables at 500.25 kPa
∴
Specific volume at state 1 is given as:
volume at state 1 is given by:
Similarly, the specific internal energy is:
At state 2:
Using steam tables at P = 500.25 kPa and T = 320° C
∴
If the boat is floating, then it's just sitting there, and not accelerating
up or down. That means the vertical forces on it must be balanced.
So if its weight (acting downward) is 100 newtons, then the buoyant
force on it (acting upward) must also be 100 newtons.
Answer:A)
Explanation:
Well It makes the Most sense. The momentum of the Cars were lessened due to the hit.
B is wrong because not only did the red car crash but so did the blue so the real answer should be both.
C makes no sense at all.
D The momentum is lost after collision so it is not the same, so this is false also.
HOPE THIS HELPS! :)
