The cloud would most likely get bigger in size. If humidity is high, there is a lot of water avalible to be made into a cloud. The larger the amount of water, the more clouds that can form.
Answer:
2 seconds
Explanation:
From the question,
Applying the equation of motion for a body falling under gravity
s = ut+1/2gt²................................. Equation 1
Where, s = hieght of fall, u = initial velocity, t = time, g = acceleration due to gravity.
Given: s = 20 m, u = 0 m/s, t = ?, g = 10 m/s²
Substitute these values into equation 1
10 = 0(t²)+1/2(10×t)
10 = 5t
Solve for t
5t/5 = 10/5
t = 2 seconds
Answer:
The ratio of the pressure at the top to the pressure at the bottom is
Explanation:
Given that,
Number of molecules
Mass
Temperature = 300 K
Height
We need to calculate the ratio of the pressure at the top to the pressure at the bottom
Using barometric formula
Where, m = mass
g = acceleration due to gravity
h = height
k = Boltzmann constant
T = temperature
Put the value in to the formula
Hence, The ratio of the pressure at the top to the pressure at the bottom is
Energy = mass * SHC * temp change
Temp change = energy/SHC * mass
42kJ - 42000J (convert kJ to J as energy is counted as J/kg)
Temp change = 42000/4200*10
= 1C
So it goes up by 1C thus the final temperature would be 26C
Or a more logical way to think of it would be that if it takes 4200J to heat up 1kg of water by 1C (SHC is 4200J/kgC) it would take ten times the amount of energy to heat up 10kg of water by 1C hence it takes 42000J.
Answer:
D). Field lines circle the Earth from east to west.
Explanation:
A microscopic force or gigantic magnetic field surrounds the Earth which functions as a force field that guards the planet against the radiations released from space. This magnetic field is characterized by the alignment of the North and South poles with the axis of rotation. Thus, the magnetic field lines of the Earth surround or circle of the Earth from East to West. Therefore, <u>option D</u> is the correct answer.
