Force /Area = Pressure
Force = Pressure * Area
Force = 1065 * 17 = 18105 N
weight = 18105 N
I hope this helps!
Answer:
10 neutrons
Explanation:
The mass of is made up of the total protons and neutrons in an atom.
Each particle has a mass of 1 amu (atomic mass unit).
All fluorine atoms have 9 protons.
If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).
This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).
If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).
Answer: You need a control group because......
Explanation: You need a control group in order to study if there is any difference in behavior between two groups when an external stimulant is introduced.
Answer:
0.33%
Explanation:
From the question given above, the following data were obtained:
Experimental value = 9.842 m/s²
Accepted value = 9.81 m/s²
Percentage error =?
The percentage error in the calculation can be obtained as follow:
Percentage error = |Experimental – Accepted| / Accepted value × 100
Percentage error = |9.842 – 9.81| / 9.81 × 100
Percentage error = 0.032 / 9.81 × 100
Percentage error = 0.33%
Therefore, the error in the calculation is 0.33%
