Airplane with nose up: The plane's speed through the air is the square root of (80 m/s squared) plus (120 m/s squared. The whole picture is a right triangle, and the plane's speed is the hypotenuse. The angle is the angle whose tangent is (80/120). You can get it from a calculator, a book, a slide rule, or online from the site that rhymes with floogle.
The man pulling the load is also a right triangle. The horizontal component is (hypotenuse) times (cosine of the angle). The vertical component is (hypotenuse) times (sine of the same angle). Fill in what you know, look up the sin and cos of 25 degrees and write those in too, and then you can solve for what you have to find.

Hello here is your answer and also please mark me as brainlest
Since one revolution around a circle is 2 pi radian; hence 1 rpm equals 2 pi radians per minute. And because a minute has 60 seconds, 1 rpm equals 1/60 revolution per second. Therefore, we have 2 pie/60 * 15.3 = 0.2513 rps. The linear velocity v = wr where w is the angular velocity in rad/s and r is the distance. So we have 0.2513 * 10.0 = 2.513 rad/s The centripetal acceleration is given by a = w^2 r = (2.513)^2 * 10 = 63.15 rad/s2 The centripetal force F = mass * centripetal acc = 75 * 63.15 = 4736.25 N The torque = centripetal force * distance = 4736 * 63.15 = 299078.4 Nm Two forces acts on the astronaut. The normal force and acceleration due to gravity.

The fact that all jobs in modern society are connected to other jobs is called division of labor.
<h3>What is division of labor?</h3>
We know that work is structured in such a way that jobs are connected. The jobs are split into smaller components and each person only does a small fragment of the that work that is to be done in a give case.

Answer: Option C
Magnetic energy | Electromagnetic energy
Answer:
(I). The initial rotation rate is 4.29 rad/s.
(II). The revolutions is 3932.
Explanation:
Given that,
Time = 1.6 h
Angular velocity = 41 rpm
(I). We need to calculate the initial rotation rate in rad/s
(II). We need to calculate the revolutions
Using formula of revolutions
Hence, (I). The initial rotation rate is 4.293 rad/s.
(II). The revolutions is 3932.
