Answer:
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. T = mg + ma.
Explanation:
Yes. Either way though, humans have more chromosomes than any other species.
Answer:
Salinometer, also called salinimeter or salimeter, device used to measure the salinity of a solution. It is frequently a hydrometer that is specially calibrated to read out the percentage of salt in a solution.
Explanation:
I hope it is correct answer
The working equation would be Vf (final velocity) = Vi
(initial velocity) + a (acceleration) t (time). The given data are the initial
velocity (5.0 m/s), acceleration (-2.5 m/s^2, negative since it is said to
decelerate) and the final velocity (0 m/s, since it will put to a stop). The
time would be 2 seconds.
Answer:
Explanation:
Given:
mass of ice melted, 
time taken by the ice to melt, 
latent heat of the ice, 
Now the heat rejected by the Carnot engine:
Since we have boiling water as hot reservoir so:
The cold reservoir is ice, so:
Now the efficiency:
Now form the law of energy conservation:
Heat supplied:
where:
heat supplied to the engine
Now the work done:
