Answer:
because the focal length is negative.
Explanation:
Power of a lens (P) is the reciprocal of its focal length (f).
Answer: 5000 kg m/s
Explanation:
Formula for momentum,
Momentum = mass * velocity.
Momentum = 500 * 10
Momentum = 5000 kg m/s
It depends.. it might have to due with environmental changes.
Eastward rides = 7+5 = 12 miles
Northward rides = 2+3 = 5 miles
This forms a right angled triangle.
The resultant triangle has legs with 12 mi and 5 mi. The hypotenuse is the resultant. Then,
Resultant = Sqrt (12^2+5^2) = 13 mi
The angle formed by the resultant to the east direction is given by:
Sin Ф = 5/13 => Ф = Sin ^-1 (5/13) = 22.62°
The correct answer is given by option 1: magnitude = 13.0 mi; direction = 22.6° North of East.
The best answer is:
C & D
**coefficients are the numbers in front of each compound
hope this helped :)
