The answer is d. most definitely.
Answer:
It ran at an average of 2 meters per second.
Explanation:
Answer:
The distance is 
Explanation:
From the question we are told that
The smallest shift is 
Generally a grid unit is 
of an arcsec
This implies that 0.2 grid unit is 
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note 
So 
Answer:
B. Cant stop things from going wrong.
Explanation:
To me it's the only reasonable answer...
Answer: 56.72 ft/s
Explanation:
Ok, initially we only have potential energy, that is equal to:
U =m*g*h
where g is the gravitational acceleration, m the mass and h the height.
h = 50ft and g = 32.17 ft/s^2
when the watermelon is near the ground, all the potential energy is transformed into kinetic energy, and the kinetic energy can be written as:
K = (1/2)*m*v^2
where v is the velocity.
Then we have:
K = U
m*g*h = (m/2)*v^2
we solve it for v.
v = √(2g*h) = √(2*32.17*50) ft/s = 56.72 ft/s
