Answer:
P=627.47W
Explanation:
To solve this problem we have to take into account, that the work done by the winch is

the force, at least must equal the gravitational force

with force the tension in the cable makes the winch go up.
The work done is

To calculate the power we need to know what is the time t. But first we have to compute the acceleration
The acceleration will be

and the time t

The power will be

The answer is....
Explanation:
How hard the surfaces push together and the types of surfaces involved.
Answer:
Vector K = 8 m
Explanation:
The given figure shows a right angle triangle JKL. It is given that :
vector L = 10 m
vector J = 6 m
We have to find vector k. We can find it by using Pythagoras theorem. According to this theorem, the sum of squares of perpendicular and the base is equal to the square of the longest side.



K = 8 m
Hence, the magnitude of vector K is 8 m.
STEP ONE:
Let you and your friend stand as far away as possible from a large reflecting wall and clap your hands rapidly at a regular rate.
STEP TWO:
Adjust this rate until each clap just coincides with the return of an echo of its predecessor, or until clap and echo are heard as equally spaced.
STEP THREE:
Use a stopwatch to find the time between claps, t. Make a rough measurement of distance to the wall, s. Thus the speed of sound, v = 2s/t
Answer:
2406 miles
Explanation:
Let A be the starting position, B the junction position and C the final position after flying the 3.5 hrs. Also, let b be the distance from the starting point:

#Distance traveled in 1.5hrs is;

#Distance traveled in next two hrs:

#Now using the Cosine Rule:

Hence, the pilot is 2406 miles from her starting position.
