Answer:
Δm = 3.0684
Explanation:
Data Given:
Atomic number of lithium = 3
Atomic mass of lithium = 7.0144 amu
Mass of 1 proton = 1.0073 amu
Mass of 1 neutron = 1.0087 amu
Solution:
Mass Defect:
Mass defect is the difference of mass number of an atom and its atomic number.
Formula used
Δm = [Z (mass of proton + mass of nutron) + ( A − Z ) mass of nutron] − m of atom
where:
Δm = mass defect (amu)
Z = atomic number
A = mass number
Put values in formula
Δm = [3 ( 1.0073 amu + 1.0087 amu) + ( 7 − 3 ) 1.0087 ] − 7.0144
Δm = [3 (2.016) + (4) 1.0087 ] − 7.0144
Δm = [(6.048) + (4.0348) ] − 7.0144
Δm = 10.0828 − 7.0144
Δm = 3.0684
Answer:
Have some attraction towards each other
Explanation:
Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.
Hope this helps :-)

Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
