Answer:b
Explanation:
velocity of a falling object increases.
so Kinetic energy of a falling object increases
height of a falling object from the ground decreases.
so the potential energy of a falling object decreases
Refer to the figure below.
The velocity diagram adds the speed of the boat (due east) as a vector to the combined speed of the water and the wind (due north) to obtain the velocity of the flag, at an angle θ, counterclockwise from the eastern direction.
By definition,
tan θ = 8/4 = 2
θ = arctan(2) = 63.4°
Answer:
The flag blows in a direction which is 63.4° measured counterclockwise from the eastern direction.
Acceleration due to gravity
It belongs to hydrides, it’s a nitrogen hydride
It is a base because of pH and because it’s a soluble vase it is an alkali
