A motorcyclist traveling due north at 50km/h. the wind appears to come from north west at 60km/h . what is the true velocity of the wind ​

6o km/h wind - cyclist wind 50 km/h = 10 km/h Head-Wind.

At NW (45 deg) True wind vel = 10 / (cos 45) = 14.1 km/h.

Explanation:

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
