If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answers
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N

Explanation:
It's called temperature.
This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.

A magnesium atom that loses 2 electrons becomes a
A) Positive ion with a smaller radius
B) Positive ion with a larger radius
C) Negative ion with a larger radius
D) Negative ion with a smaller radius
Answers
Answer:
A
Explanation:
because the atomic radius reduced by loosing one energy level leading to a positive ion in the resulting ion
The study of chemicals and their bond is called chemistry.
The correct answer is A.
The metals have the property to lose electrons to become stable compounds.
In magnesium, the total number of electrons is 12. In a valance shell, they have 2 electrons.
when they lose or donate the two electrons to the other. The outer shell will be empty and the force of the nucleus remains in the inner shell.
The loss of electrons leads to a decrease in the size of an atom and form positive ions.
Hence, the correct answer is A that is a Positive ion with a smaller radius.

Which of the following is not a sign that chemical reaction has taken place?
a. temperature change
b. formation of a liquid
c. color change
d. formation of a gas
Answers
Answer:
a
Explanation:
uh process of elimination
Temperature change, phase change to liquid or gas are all physical changes not chemical reactions. A color change indicates a chemical reaction has taken place.
What is a chemical change?Chemical changes are taking place by the breaking or making of chemical bonds. It results in the formation of a new product which is having different properties than the initial substances.
Physical changes does not involve any change in chemical bond. Phase changes, change in size, shape, conductivity, solubility etc. are physical changes. A change in temperature phase conversion into gas or liquid are all physical changes.
A change in color indicates that a new product is formed there. For example reddish brown rust is iron oxide formed by the reaction of Fe with oxygen. Therefore, option c is correct.

law of conservation of matter

Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.
Explanation:
brainliest?
Answer: Hope this helps:)
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substances react by following certain laws. These laws are called the laws of chemical combination. Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

3. What mass of water vapor condenses if 435 kJ of heat are released in the process? a a 10.79 b 982 g C 1.30 x 10 g d 1939
Answers
Mass of water vapor = 193 g
Further explanationGiven
435 kJ of heat are released
Required
mass of water vapor
Solution
The heat to change the phase can be formulated :
Q = mLf (melting/freezing)
Q = mLv (vaporization/condensation)
Lv for water = 2256 kJ/kg or 2256 J/g or 40.7 kJ/mol
So the mass of water vapor :
[tex]\tt m=\dfrac{Q}{Lv}\\\\m=\dfrac{435000~J}{2256~J/g}\\\\m=192.8\approx 193~g[/tex]
