Answer:
before this type of attack, high acceleration is the most important thing.
Explanation:
As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.
Consequently, before this type of attack, high acceleration is the most important thing.
Answer:
time is 5.973826 sec
Explanation:
Given data
diameter D = 6.0 mm 6× 
m
separated d = 0.010 m
distance (dis) 185 m
speed s = 16 m/s
wavelength = 550 nm = 550 
m
to find out
How much time passes
solution
we know that for resolution we use Rayleigh's Criterion i.e
θ = 1.22 wavelength / diameter = separated / distance 1
we calculate distance 1 by put value wavelength, diameter and separated
distance 1 = diameter × separated / 1.22 wavelength
distance 1 = 6× × 0.010 / 1.22 × 550 ×
distance 1 = 89.418778
so time will be i.e = distance (dis) - distance 1 / speed
time = ( 185 - 89.418778) / 16
time = 5.973826 sec
time is 5.973826 sec
Answer:
If air resistance is taken as negligible, then the ball is in freefall the moment it is thrown so gravity is the only force acting on the object. If air resistance is not negligible then gravity will be the greatest force acting on the ball while it is going up and coming down, because Fair has to be less than gravity at all times otherwise the atmosphere would wither away.
-- The mass of the sun never increases.
-- It does decrease, but not nearly enough to have any noticeable
effect on the orbital motion of the Earth, or any other planet.
-- When Earth is closer to the sun, it moves faster in its orbit.
-- When Earth is farther from the sun, it moves slower in its orbit.
-- The result is that the line from the sun to the Earth always covers
the same amount of area in the same length of time.
-- Johannes Kepler noticed this, and it's his Second Law of planetary motion.
-- Newton showed that if his equations for gravity and motion are correct,
then planets MUST behave this way.
