Objects can have the same mass (but different <span>compositions). Only mass or volume cannot tell you if the object is solid or vo</span>lumes) or same volume (but different masses)
Answer:
The value is 
Explanation:
From the question we are told that
The potential of the proton is 
Generally the momentum of the particle is mathematically represented as

Here e is the charge on the proton with value

m is the mass of the proton with value 
So

=> 
So the de-Broglie wavelength isis mathematically represented as

Here h is the Planck's constant with value

=> 
=>
The mass of the star of the distant solar system is 82 * 10²² kg and the mass of the planet of the distant solar system is 8.58 * 10²⁵ kg
The planet stays in its orbit and moves in a centripetal motion due to the gravitational force of attraction between the planet and the star.
Fc = m v² / r
Fg = G M m / r²
Fc = Fg
m v² / r = G M m / r²
v² = G M / r
M = r v² / G
g = Acceleration due to gravity
G = Gravitational constant
M = Mass of star
r = Distance between both bodies
G = 6.67 * 10⁻¹¹ N m² / kg²
r = 8.6 * 10¹¹ m
T = 402 days = 3.47 * 10⁷ s
v = 2 π r / T
v = 2 * 3.14 * 8.6 * 10¹¹ / 3.47 * 10⁷
v = 15.56 * 10⁴ m / s
Ms = 8.6 * 10¹¹ * 15.56 * 10⁴ / ( 6.67 * 10⁻¹¹ )
Ms = 20.1 * 10²⁶ kg
F = G M m / r²
F = m g
Equating,
m g = G M m / r²
Mp = g r² / G
Mp = 63.6 * ( 1.8 * 10⁷ / 2 )² / 6.67 * 10⁻¹¹
Mp = 8.58 * 10²⁵ kg

Answer:
<em>1182.6 billion gallons of gasoline</em>
<em></em>
Explanation:
For the 350 million population of America, one of two people represents half of this population, which is 135/2 = 67.5 million.
The average distance driven per day by this amount of people is 40 miles, and the average mileage is 25 mpg (miles per gallon).
This means that for the forty miles driven per day, the gallon of fuel used is
==> 25 miles = 1 gallon
40 miles =
gallons.
= 40/25 = 1.6 gallons, which means that each of the 67.5 million Americans consumes 1.6 gallons of gasoline on an average, per day.
There are 365 days in a week, so in a year, 365 x 1.6 = 584 gallons of fuel is used by one of these 67.5 million Americans.
Which is 584 x 67.5 million = 39.42 billion gallons per year.
In the next 30 years that is 30 x 39.42 billion gallons = <em>1182.6 billion gallons of gasoline</em>
