Answer:
The mass of the planet is 
Explanation:
Given that,
Time period = 42 hours = 151200 sec
Orbital radius = 0.002819 AU = 421716397.5 m
Mass of moon 
We need to calculate the mass of the planet
Using Kepler’s third law
Where, a = orbital radius
T = time period
G = gravitational constant
M = mass of moon
m = mass of planet
Put the value into the formula
Hence, The mass of the planet is
Answer:
3.16X10∧-11 m
Explanation:
1/2 mv2 = qV (KE = Electric potential energy)
velocity = √2qV/m = √( 2X 1.6X10∧-19 X 1500/9.11X10∧-31)
2.3X10∧7m/s
now use De Broglie equation
λ = h/mv
= 6.62X10∧-34/( 9.11X10∧-31 X 2.3X10∧7)
3.16 X 10∧-11 m
or
use the above equations and substitute to get the final eqiation
λ = h/√(2mqV) = 3.16X 10∧-11 m
Answer:
(1) how thick the fluid is <u>viscosity</u>
Explanation:
This is a type of friction experienced within liquids and gases. It depends on:__________.
(1) how thick the fluid is_______?
(2) how the shape of the object?
(3) how the speed of the object?
the thickness of a fluid is known as viscosity. the more viscous a fluid is the more frictional force is exerted on an object by the fluid
frictional force is an opposing force that resist the movement of two surfaces in contact, there are to types 0f frictional force
1. static frictional force
2. dynamic frictional force
Answer:
the volume occupied by air is not constant because as we add ethanol in it it will keep decreasing.
vapor pressure calculated and clausius-Claperon plot are affected because volume and vapor pressure are directly proportional.
Explanation:
by charle's law volume and temperature are directly proportional and vapor pressure is directly proportional to temperature thus volume and vapor pressure are also directly proportional by this relation
