Answer:
A. The project's energy costs will decrease
Explanation:
Since the project is located in an area with a demand-response program and on a site that has enough room for a wind-turbine to allow for on-site renewable energy.
Hence, the project's energy costs will decrease very well because it's implementing both of these strategies;
- Area with demand-response program.
- On-site renewable energy.
If 56.5kJ are needed to raise the temp by 90°C and if the heater is 60% efficient that means that:
60% X y = 56.5kJ
where y is the electrical energy in kJ that the heater will use.
y = 94.2kJ
Answer:
a) 
b) 
Explanation:
From the question we are told that:
Velocity 
Time 
a)
Generally From Newton's motion equation for Average acceleration is mathematically given by

Since its from Rest Therefore



b)
Generally the equation for Average Velocity is mathematically given by







I think trace 1 is ac and trace 2 if dc but i’m not sure what will happen when a higher frequency is added?
Answer:
Increase by a factor of 4.
Explanation:
The acceleration of a car moving with speed v in a circle of radius R is given by:

Now if we double the speed
in the equation above, it becomes
. Thus:

Therefore the acceleration is increased by a factor of 4.
