Answer:
Final Temperature of the steam tank = 456.4°C
Explanation:
Assuming it to be a uniform flow process, kinetic and potential energy to be zero, and work done and heat input to be zero also. We can conclude that,
Enthalpy of the steam in pipe = Internal Energy of the steam in tank
Using the Property tables and Charts - Steam tables,
At Pressure= 1 MPa and Temperature= 300°C,
Enthalpy = 3051.2 kJ/kg
At Pressure= 1 MPa and Internal Energy= 3051.2 kJ/kg,
Temperature = 456.4°C.
Answer:
truck 1 has the most velocity
Explanation:
Because it weights less which means it faster and yea

Answer:
T= 1 s
Explanation:
Given that
When x= cm ,T= 1
we know that time period of spring mas system given as
![T=2\pi \sqrt{\dfrac{m}{k}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cdfrac%7Bm%7D%7Bk%7D%7D)
T= Time period
m= mass
k=spring constant
So from above equation we can say that time period of system does not depends on the value of x.
So when x= 10 cm ,still time period will be 1 s.
T= 1 s
The red box must way more. Gravitational potential energy is the product of a an objects mass times the acceleration due to gravity (which is constant on earth) times its height. Since the objects are on the same shelf they are at the same height, and since gravitational acceleration is constant as long as we stay on planet earth, then the mass is the only possible thing that could have changed. This means that the red box must weigh more than the blue box.
