Answer:
Force = Mass x Acceleration
12 x 5 = 60
60 Newton’s is your final answer
Answer:
<u>Part -A</u>
The change in the entropy from largest to smallest is 3>2=4 >1 >5>6.
<u>Part-B</u>
Change in entropy over a complete cycle is 1 =2 = 3= 4 = 5 = 6
Explanation:
<u>Part -A</u>
The change in entropy for the reversible process that transfers the heat energy 'Q' at temperature 'T' is
1)
2)
3)
4)
5)
6)
Therefore, The change in the entropy from largest to smallest is 3>2=4 >1 >5>6.
<u>Part-B</u>
Initial and final states of complete cycle are equal. after complete the one cycle the system returns to the original state. So, the change in the entropy will be the zero
Therefore, Change in the overall cycle is 1 =2 = 3= 4 =5=6
It is a compound because it cannot be separated by physical means and i<span>t is a homogeneous mixture </span>
Answer:i
i believe its contraction but i might be wrong

Answer:
Option D. ⁴⁰₁₉K⁺¹
Explanation:
The following data were obtained from the question:
Proton number = 19
Neutron number = 21
Electron number = 18
Complete symbol of isotope =.?
Next, we shall determine the atomic number of the isotope. This is illustrated below:
Atomic number of an element is simply the number of protons in the atom of the element. Thus,
Atomic number = proton number
Proton number = 19
Therefore,
Atomic number = proton number = 19
Since the atomic number of the isotope is 19, the isotope is simply potassium with symbol K.
Next, we shall determine the mass number of the isotope. This can be obtained as follow:
Proton number = 19
Neutron number = 21
Mass number =.?
Mass number = Proton + Neutron
Mass number = 19 + 21
Mass number = 40
Next, we shall determine the charge on the isotope. This can be obtained as follow:
Proton number = 19
Electron number = 18
Charge =.?
Charge = Proton – Electron
Charge = 19 – 18
Charge = +1
Summary:
Atomic number = 19
Mass number = 40
Symbol = K
Charge = +1
Complete symbol = ⁴⁰₁₉K⁺¹
