Answer:
<h2>The temperature of the gas is 48.75 Kelvin.</h2>
Explanation:
Using the ideal gas equation as shown
PV = nRT where;
P is the pressure of the gas in ATM
V is the volume of the gas
n is the number of moles
R is the ideal gas constant
T is the temperature in Kelvin
From the formula, 
Given the following parameters V = 1litre, n = 0.5moles. pressure = 2ATM
R = 0.08206 atm L/molK
On substituting to get the temperature we have:
Answer:
76.1N
Explanation:
Given parameters:
Mass of the ball = 7.77kg
Unknow:
Weight of balloon = ?
Solution:
Weight is the vertical force applied on a body.
Weight = mass x acceleration due gravity
So;
Weight = mass x acceleration due to gravity
So;
Weight = 7.77 x 9.8 = 76.1N
Answer:
The rate of change of velocity is acceleration. It's SI unit is m/s².
Answer
given,
wavelength of light in air = 700 nm
Wavelength of light in water = 530 nm
We know that speed of light changes when it moves from one medium to another.
And the frequency of the wavelength does not changes if the medium changes.
we also know that,
v = ν λ
From the above equation we can say that if frequency is constant so, with the change in velocity changes wavelength will also change.
Hence, wavelength is the property of the wave which determines color.
