Well it's a volcano that hasn't erupted. except the 1980 eruption of Mount St Helen. They're exctint, Scientist believe that it will never erupt again
Answer:
Florida's Cape Canaveral was central to the US victory in the space race. An isolated air force base was in Cape Canaveral near the ocean. This location allowed NASA scientists to test rockets freely.
Explanation:
The distance covered by the car is 39.9 m
Explanation:
Since the car is slowing at constant rate, it means that its acceleration is constant, therefore we can solve the problem by using the following suvat equation:
![s=(\frac{u+v}{2})t](https://tex.z-dn.net/?f=s%3D%28%5Cfrac%7Bu%2Bv%7D%7B2%7D%29t)
where
s is the distance covered
u is the initial velocity
v is the final velocity
t is the time elapsed
For the car in this problem, we have
u = 19 m/s (initial velocity)
v = 0 (final velocity)
t = 4.2 s (time elapsed)
Therefore, the distance covered is
![s=(\frac{19+0}{2})(4.2)=39.9 m](https://tex.z-dn.net/?f=s%3D%28%5Cfrac%7B19%2B0%7D%7B2%7D%29%284.2%29%3D39.9%20m)

Answer:
e. All of the above are projectile
Explanation:
A projectile is an object with motion, aka a non-zero speed. A cannonball throwing straight up, rolling down a slope, rolling off the edge of a tale, thrown through the air have motion. They all have speed and kinetic energy. Therefore they can all be considered a projectile.
Answer:
V = 5 Volts
Explanation:
Given the following data;
Work done = 20 Joules
Charge = 4 Coulombs
To find the potential difference;
Mathematically, the work done in moving a charge is given by the formula;
W = qv
Where;
W is the work done
q is the quantity of charge
v is the potential difference
Substituting we have;
20 = 4 * v
V = 20/4
V = 5 Volts
