Answer:
wind has two important things that is direction and speed.
Answer:
a bathtub full of warm water
Explanation:
Even though the water in a filled bathtub may be at the same temperature as water in a teacup, the water in the bathtub has more thermal energy because it contains a greater number of water molecules.
Answer:
9.6 m
Explanation:
This is a case of motion under variable acceleration . So no law of motion formula will be applicable here. We shall have to integrate the given equation .
a = 3.6 t + 5.6
d²x / dt² = 3.6 t + 5.6
Integrating on both sides
dx /dt = 3.6 t² / 2 + 5.6 t + c
where c is a constant.
dx /dt = 1.8 t² + 5.6 t + c
when t = 0 , velocity dx /dt is zero
Putting these values in the equation above
0 = 0 +0 + c
c = 0
dx /dt = 1.8 t² + 5.6 t
Again integrating on both sides
x = 1.8 t³ / 3 + 5.6 x t² /2 + c₁
x = 0.6 t³ + 2.8 t² + c₁
when t =0, x = 0
c₁ = 0
x = 0.6 t³ + 2.8 t²
when t = 1.6
x = .6 x 1.6³ + 2.8 x 1.6²
= 2.4576 + 7.168
= 9.6256

White dwarfs
<u>Explanation:</u>
Hertzsprung-Russel graph is a 2-dimensional graph, plotting star’s luminosity against temperature they emit.
White dwarfs are the star exhibiting high temperatures and low luminosities. These stars are extremely dense and mass comparable to that of the sun.
The main cause of low luminosities in the absence of fusion reaction inside the core of the star. Faint luminosity is provided by the thermal energy of the star. They are considered to be in the final stage of evolution having masses in the range of 10 solar mass (hence not enough to form a star)
