Answer:
Therefore the number of proton in the given system is 450.
Explanation:
Given that, a system has 1223 particles.
Let x number of proton be present in the system.
Then the number of electron is =(1223-x)
The charge of a proton is = 1.602×10⁻¹⁹ C
The charge of an electron = - 1.602×10⁻¹⁹ C
The charge of x protons is =( 1.6×10⁻¹⁹×x) C
The charge of (1223-x) electrons is = - 1.6×10⁻¹⁹ (1223-x) C
According to the problem,
(1.6×10⁻¹⁹×x) +{ - 1.6×10⁻¹⁹ (1223-x)}= -5.328×10⁻¹⁷
⇒1.6×10⁻¹⁹(x-1223+x)=-5.328×10⁻¹⁷
⇒2x-1223= -333
⇒2x= -333+1223
⇒2x=900
⇒x=450
Therefore the number of proton is 450.

Answer: The magnitude of torque is 38.7Nm
Explanation: Please see the attachment below
The magnitude of the torque on the door about its h1nges due to the applied force is 38.7 Nm.
How to calculate the magnitude of the torque?
The magnitude of the torque on the door about its h1nges due to the applied force is calculated by applying the following formula as shown below;
τ = rF
where;
- r is the perpendicular distance of the applied force
- F is the applied force
The given parameters include;
perpendicular distance, r = 86 cm = 0.86 m
the applied force , F = 45 N
The magnitude of the torque on the door about its h1nges due to the applied force is calculated as;
τ = rF
τ = 0.86 m x 45 N
τ = 38.7 Nm

Answer:
s = 6.25 10⁻²² m
Explanation:
Polarizability is the separation of electric charges in a structure, in the case of the atom it is the result of the separation of positive charges in the nucleus and the electrons in their orbits, macroscopically it is approximated by
p = q s
s = p / q
let's calculate
s = 1 10⁻⁴⁰ / 1.6 10⁻¹⁹
s = 0.625 10⁻²¹ m
s = 6.25 10⁻²² m
We see that the result is much smaller than the size of the atom, therefore this simplistic model cannot be taken to an atomic scale.

Explanation:
The reason for the more concentration of carbon dioxide in the atmosphere of Venus than in the Earth -
On the Earth , most amount of the carbon dioxide is in the ocean water and in sea sediments .
Considering Venus , in the planet Venus , there is no Ocean water , hence , carbon dioxide can not get dissolved into the water , hence , it is found in the atmosphere .
So , the escape velocity for carbon dioxide on Mars is smaller than Venus .
