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
∴
Answer:
241.7 s
Explanation:
We are given that
Charge of particle=
Kinetic energy of particle=
Initial time=
Final potential difference=
We have to find the time t after that the particle is released and traveled through a potential difference 0.351 V.
We know that
Using the formula
Initial voltage=
Using the formula
Hence, after 241.7 s the particle is released has it traveled through a potential difference of 0.351 V.
Really sad try not to let it get to you
Answer:
unless acted upon by an unbalanced force.
Explanation:
If a ball is rolling, it will continue to roll forever, unless it is acted upon by an unbalanced force. For example, the friction of the floor it's rolling on slows it down. The density of the air hitting it also slows it down.
Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
