The answer is C.. because angles at north start from 0..
Answer:
Explanation:
Give it that,
Initial velocity
u = 22m/s
Deceleration a = - 0.15m/s2
Time taken to travel a station long of 210m
Using equation of motion
Let know the final velocity, when it leaves the station
v² = u²+2as
v² = 22²+2×(-0.15)×210
v² = 484—63
v² = 421
v =√421
v = 20.52m/s
Then,
Using equation of motion to find time taken
v = u + at
20.52 = 22 +(-0.15)t
20.52-22 = -0.15t
-0.15t = -1.48
t = -1.48/-0.15
t = 9.88 sec
Answer:
The value in Newton is 
The value in pounds is 
Explanation:
From the question we are told that
The mass of the spacecraft is 
The distance above the earth is 
Generally the gravitational force with respect to the earth is mathematically represented as
Here 
is the mass of earth with value 
is the radius of the earth with value 
G is the gravitational constant with value 
So
Converting to pounds
In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.
Is there anything else you can add for context
