Answer:
200 m/s
Explanation:
Given that,
A plane is moving due north, directly towards its destination. Its airspeed is 200 mph. A constant breeze is blowing from west to east at 60 mph.
We need to find the rate at which the plane is moving towards North. It can be given by :

Where
is the angle with the North

Hence, the plane is moving at a rate of 200 m/s.
Answer:
The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to originate from a common point behind the mirror. If you walk behind the mirror, you cannot see the image, because the rays do not go there
Answer:
dosimetry
Explanation:
dosimetry is the determination of energy imparted to matter by radiation
D^2 = p^2 + q^2 - 2 pq cos D
d^2 = (4.24)^2 + (4.24)^2 - 2. (4.24) (4.24) cos 68
d^2 = 2 (4.24)^2 - 2. (4.24) (4.24) cos 68
d = 4.74
so the answer will be letter. C
hope this helps
Answer:
Explanation:One method of calculating average speed is to divide the total distance by the total time spent
d1=d2= 12 miles
d1=d2= 19312.1 m



There is slight difference between the average speeds due to the reason that average speed is not just the midpoint of the speed but is the total distance traveled by total time.
