Answer:
No it cannot
Explanation:
The mass number of an atom is equal to the sum of the number of neutrons plus the number of protons in that atom. While the atomic number isjust the number of protons in it.
Therefore the number of protons + number of neutrons cannot be smaller than the number of protons.

Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.
so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant
What is the as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T
Answer:
The gas A and B have same internal energy
Explanation:
From the question we are told that
Generally the equation of temperature is mathematically given as
And
Generally the change in temperature is mathematically given as
Generally the change in internal energy
Therefore with
The gas A and B have same internal energy
Answer:
The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.
The orbital diagram of an orbit containing 16 electrons will be as follows:
1s²2s²2p⁶3s²3p⁴
- The maximum number of electrons in each sublevel of the orbitals are:
- 2 electrons for s-sublevel with one orbital
- 6 electrons for p-sublevel with three orbital
- 10 electrons for d-sublevel with five orbital
- 14 electrons for f-sublevel with seven orbital

Explanation:
Given:
- mass of skier,
- initial velocity of skier,
- height of the hill,
- spring constant,
<u>final velocity of skier before coming in contact of spring:</u>
Using eq. of motion:
<u>Now the time taken by the skier to reach down:</u>
<u>Now we calculate force using Newton's second law:</u>
<u>∴Compression in spring before the skier momentarily comes to rest:</u>
Answer:
time taken with speed 23 km/h will be 1.8 hours or 1 hour 48 minutes
Explanation:
Given:
Time is inversely proportional to the speed
mathematically,
t ∝ (1/r)
let the proportionality constant be 'k'
thus,
t = k/r
therefore, for case 1
time = 3 hr
speed = 14 km/hr
3 = k/14
also,
for case 2
let the time be = t
r = 23 km/h
thus,
we have
t = k/23
on dividing equation 2 by 1
we get
or
or
t = 1.8 hr = or 1 hour 48 minutes ( 0.8 hours × 60 minutes/hour = 48 minutes)
