A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?
Explanation:
Area = Length × Breadth
A = 4 × 6
A = 24m square/ 24m sq.
Force = Pressure × Area
Force = 60,000 N/ 60,000 Newton
Pressure = Force/ Area
P = 60,000/24
P = 2500 Pa

How many nitrogen atoms are in the chemical
formula below?
5C8H10N402
Answer:
4 ATOME nitrogen in the formula
There are 20 nitrogen atoms in the chemical formula mentioned.
What is chemical formula?Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.
Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.
It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.They are used to describe the chemical reactions.
There are four types of chemical formula:
1)empirical formula
2) structural formula
3)condensed formula
4)molecular formula

Which of the subatomic particles are most responsible for the identity of an element?
neutrons
electrons
atoms
protons
Protons
Protons are the subatomic particle that determines the identity of an element.
Answer:
Explanation:Protons and neutrons are located in the nucleus of an atom and determine the mass of an atom. Protons have a positive electrical charge and electrons have a negative electrical charge. Atoms that have the same number of protons and electrons do not have an electrical charge.

Which two parts are needed to make a neutral atom of nitrogen A. Electron clouds with a total of 14 electrons B. Electron cloud is a total of seven electrons C. A nucleus with seven protons and seven neutrons D. A nucleus with three protons and four neutrons
Answer:
B. Electron cloud is a total of seven electrons
C. A nucleus with seven protons and seven neutrons
Explanation:
An atom is consist of three subatomic particles: electron, proton, and neutron. Proton are positively charged particles and neutron have neutral charge, they both are present inside the nucleus in the center of the atom whereas electrons are negatively charged and surround the nucleus in a definite orbit.
Nitrogen is an element with 7 electrons in its outer orbit. As electrons are negatively charged so nitrogen atom will require 7 protons inside the nucleus to form a neutral atom of nitrogen. So, A neutral atom of nitrogen will consist of 7 electrons and 7 protons.
As, neutron has neutral charge so it will not affect the composition of neutral atom of nitrogen.
Hence, the correct options are:
"B. Electron cloud is a total of seven electrons
C. A nucleus with seven protons and seven neutrons ".
Answer:
B and C

Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?
Answer:
Explanation:
As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.
However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.
Please note this isn't a scientific fact and just a possibility as requested in the question.

A piece of aluminum has a mass of 12.0 g. When it is placed into a graduated
cylinder with 14.0 mL of water, the water level rises to 18.5 mL. What is the density
of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL
Answer:
The answer is 2.7 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 12 g
volume = final volume of water - initial volume of water
volume = 18.5 - 14 = 4.5 mL
So we have
[tex]density = \frac{12}{4.5} \\ = 2.66666666...[/tex]
We have the final answer as
2.70 g/mLHope this helps you
