Answer:
Explanation:
Given
mass of saturated liquid water 
at 
specific volume is 
(From Table A-4,Saturated water Temperature table)
Final Volume 
Specific volume at this stage
Now we see the value and find the temperature it corresponds to specific volume at vapor stage in the table.
Answer:
Explanation:
Calories to be burnt = 3500 - 2500 = 1000 Cals .
Efficiency of conversion to mechanical work is 25 % .
Work needed to burn this much of Cals = 1000 x 100 / 25 = 4000 Cals.
4000 Cals = 4.2 x 4000 = 16800 J .
Work done in one jump = kinetic energy while jumping
= 1/2 m v²
= .5 x 70 x 3.3²
= 381.15 J .
Number of jumps required = 16800 / 381.15
= 44 .
There are longitudinal and transverse. Both types of mechanical waves require a medium, transport energy, and have defined wavelengths, frequencies, and speeds.
Differences are that transverse waves oscillate along a direction perpendicular to the direction of travel (like shaking a rope up and down). Longitudinal waves like oscillations along a spring and sound waves, oscillate back and forth along the direction of travel.
mass and velocity
Explanation:
Momentum depends on two important factors which are the mass and velocity of a body.
Momentum = mass x velocity
- Momentum can be defined as the product of mass and velocity.
- It is a vector quantity that has both magnitude and directions.
- Momentum is a very important quantity in physics as it shows the impact of a force on another.
- The unit is Kgm/s²
- It is the same as impulse.
