Answer:
the evaluation in SI unit will be 
Explanation:
We have evaluate 
We know that 1 mm 
So 240 mm 
Newton can be written as 
So 
So the evaluation in SI unit will be
Answer:
a
Explanation:
that is what energy efficiency is
Answer:
Explanation:
When NaOH is added to a solution of Mg(NO3)2 , a precipitate forms which will be Mg(OH)2 . When temperature of the solution is raised , Mg(OH)2 gets dissolved.
According to Le Chatelier principle , reaction tends to proceed towards the balance point when , the effect of external change in temperature or pressure etc is reduced.
Addition of heat , promotes dissolution. It is possible only when the process of dissolution is endothermic. Additional dissolution on heating helps in reducing the temperature because , process of dissolution is endothermic.
Dissolution of Mg(OH)₂ is endothermic.
Answer:
Because IC microcomputers are smaller and more versatile than previous control mechanisms, they allow the equipment to respond to a wider range of input and produce a wider range of output. They can also be reprogrammed without having to redesign the control circuitry
Explanation:
It is a tool used to measure Low pressure
