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:
Σ/ε
σ = F/A
ε = ΔL/L
F = force
A = area
L = lenght
ΔL = |old lenght - new lenght|
Answer:
The bonds can shift because valence electrons are held loosely and more freely

Answer;
= 3.86 × 10^8 Meters
Explanation;
-The distance between the Earth and the moon is 386000 km
But; 1 km = 1000 m
Therefore; 386000 km will be equivalent to;
= 386000 × 1000
= 386000000 m
= 3.86 × 10^8 meters
Answer: The first one
Explanation: I think it's the first one because it says what is the "least" gravitational potential energy story between the prairie dog and Earth that said resting in its borrow is using less energy
