Answer:
Both heat pump has same COP
Explanation:
Given that a reversible heat pump and a Carnot heat pump which is operating between the same temperature limits will have the same COP because the temperature limits are same, that is the source temperature and the sink temperature. Also because we know that a Carnot cycle is a totally reversible cycle. Therefore for a perfectly reversible Carnot cycle, the COP will be same for a reversible heat pump and a Carnot heat pump operating between two same thermal reservoirs.
Thus, both heat pump will have same COP.
Answer:
Torque at input shaft will be 176.8695 N-m
Explanation:
We have given input power 
Angular speed = 2300 rpm
For converting rpm to rad/sec we have multiply with 
So 
We have to find torque
We know that power is given by 
, here 
is torque and 
is angular speed
So 
So torque at input shaft will be 176.8695 N-m
The lowest level of acceleration should be use when accelerating on a short highway entry ramp.
<h3>What is an acceleration?</h3>
This means the rate at which velocity changes with time in terms of both the speed and direction.
In a machine, this means rate at which a vehicle can increase its speed in terms of the time that it takes to reach a particular speed.
Because the short highway entry ramp need careful driving, then, the lowest level of acceleration should be use when accelerating on a short highway entry ramp.

Answer:
a) the two-way concrete joist framing system
Explanation:
A waffle slab is also known as ribbed slab, it is a slab which as waffle like appearance with holes beneath. It is adopted in construction projects that has long length, length more than 12m. The waffle slab is rigid, therefore it is used in building that needs minimal vibration.
Answer:
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.
