Answer:

Since their wings and body develop the drag. When there is warm air then they expand their wings. Since,soaring birds and glider pilots have no engine, they always maintain their high speed to lift their weight in air for hours without expending power by convection

A hiker walks 15km due east then heads due north for 8km . What is the direction of the resultant vector?
4vir4ik [10]

his displacements are given as

d_1 = 15 km East

d_2 = 8 km North

now we can find the direction of displacement by using the concept

\theta = tan^{-1}\frac{\deta y}{\delta x}

\theta = tan^{-1}\frac{8}{15}

\theta = 28.1 degree

magnitude of displacement is given as

d = \sqrt{x^2 + y^2}

d = \sqrt{15^2 + 8^2}

d= 17 km

<em>so the displacement is 17 km at angle 28.1 degree North of East</em>

What other types of energy are present when turning a generator that were not mention in question ? Explain where in the process
klemol [59]

Answer:

When an object is in motion, there is energy associated with that object. Why should that be the case? Moving objects are capable of causing a change, or, put differently, of doing work. For example, think of a wrecking ball. Even a slow-moving wrecking ball can do a lot of damage to another object, such as an empty house. However, a wrecking ball that is not moving does not do any work

(hope it helps :p    )

13. Momentum is an object’s mass times velocity. Which has more momentum? A paper airplane with a mass of 10g flying at a veloci
Ivenika [448]
Since the velocity of the real plane is 0, p=mv=0.  So the paper airplane actually has more momentum since it's value is not 0.
