Explanation: took the quick check
Answer:
- Corey's max speed is

- the distance Corey's covers in z seconds is



Explanation:
<h3>Corey's max speed</h3>
For constant speed, we know:

The distance between the 80 meters and the 45 meters is:

and the time it took to reach the 80 meter will be:

So, Corey's max speed is

<h3>
How far runs Corey</h3>
As the velocity of Corey's is
, the distance Corey's covers in z seconds is


<h3>What is Corey's distance from the starting line</h3>
At time 7 + z seconds the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:


At time x ( x greater or equal to 7 seconds) the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:


Answer:
It will take 313.376 sec to raise temperature to boiling point
Explanation:
We have given that potential difference V = 120 Volt
Current i = 4.50 A
So resistance 
Heat flow in resistor will be equal to 
It is given that this heat is used for boiling the water
Mass of the water = 0.525 kg = 525 gram
Specific heat of water 4.186 J/gram/°C
Initial temperature is given as 23°C
Boiling temperature of water = 100°C
So change in temperature = 100-23 = 77°C
Heat required to raise the temperature of water 
So 
t = 313.376 sec
So it will take 313.376 sec to raise temperature to boiling point
It looks like a refractor.
