Answer:
V = 308.06 miles/hour
θ = 13.13° west of north.
Explanation:
Airplane speed = V₁ = 300 miles/hour
Wind speed = V₂ = 70 miles/hour
Resultant speed of the plane = V = ?
As airplane is trying to fly straight North and wind is blowing toward the west. So the angle between airplane velocity and wind velocity is 90°.
By Pythagoras Theorem
V =
V =
V = 308.06 miles/hour
θ = tan⁻¹(70/300)
θ = 13.13° west of north.

Answer:
Height of the image is 9.06 cm
Explanation:
As we know that the person is standing 250 cm from the lens
Now we know that the focal length of the lens is
f = 15 cm
now by lens formula we have
now we know by the formula of magnification
now we have
To solve this problem we will apply the concepts related to the conversion of units for which we will have that 1 slug is equal to 14.59kg. At the same time we will use Newton's second law for which weight is defined as the product between mass and acceleration (Due to gravity). This is then
A: Using the conversion ratio of slug to kilogram we have to,
Then
B: Using Newton's second law we have to,
