The momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball
Momentum is defined as the product of mass and velocity i.e
Momentum = mass × velocity
If we keep the velocity of the object constant, the momentum will depend on the mass of the object.
Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.
From the question given above,
Mass of tennis = 0.5 Kg
Mass of basketball = 2 Kg
Mass of bowling ball = 5 kg
We can see that the bowling ball has a higher mass.
Therefore, the momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball

explain why the pressure in a sealed container of gas decreases when heat is added to the system?
Answer:
the question is bogus
see explanation
Explanation:
explain why the pressure in a sealed container of gas decreases when heat is added to the system?
when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!
IT DOES NOT DECREASE

What structural characteristic do all of the atoms within a group (vertical columns) have in common?
Answer:
The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.
hope this helps
Explanation:
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

Which type of dry-chemical fixed application method introduces a concentration of agent into a closed area
Actuating mechanism is the dry-chemical fixed application method which
introduces a concentration of agent into a closed area.
The actuating mechanism is commonly used in piping systems and
involves the transport of a control member in automatic or remote control
systems.
The closed system makes manual navigation very difficult which is why the
actuating mechanism in automatic systems are usually used to make it less
tedious and accurate.

Explanation:
When 50 cm³ of hydrocarbon Y is burnt, it reacts with exactly 300 cm³ of oxygen to form 200 cm³ of carbon dioxide. Water is also formed in the reaction. Deduce the equation for this reaction. Explain your reasoning.
Answer:
C2H4 + 3O2---> 2CO2 + 2H2O
Explanation:
The volume of the gas is directly proportional to the no. of moles of the gas at constant temperature and pressure.
So Volume of O2 : Volume of CO2 = 300: 200
= 3:2
So we can add 3 and 2 stoichiometric coefficients to O2 and CO2 respectively.
Then we can see that out of total 3×2 atoms of O, 2×2 atoms of O have been incorporated into CO2. Therefore the remaining 2 O should be in the H2O ( during complete combustion of hydrocarbon we get CO2 and H2O as products)
So we can add 2 in front of H2O..
Then calculate the total no. of C and H atoms in the products side to find the no. of C and H atoms in the hydrocarbon.
C=2
H=4
So the hydrocarbon burnt has the formula C2H4.
To solve such this we must know the concept of combustion reaction. Therefore, The balanced chemical reaction will be
C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Combustion reaction is a reaction in which a substance, basically hydrocarbons burns in presence of oxygen to produce carbon dioxide and water.
At constant temperature and pressure, the number of moles of the gas directly relates to the volume of the gas.
Volume of O[tex]_2[/tex]: Volume of CO[tex]_2[/tex]
= 300: 200
= 3:2
The chemical reaction will be
C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O
Therefore, the chemical reaction will be
C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

how many grams of water are needed to produce 250 j of energy when the temperature changes from 21 to 18.5
Answer:
So if you want to raise the temperature of that one gram from 19 to 35 degrees, that same gram will need 35 −19 = 16 times as much heat. And if you want to raise the temperature of 193 grams in stead of just 1 gram, you will need 193 times as much heat.

If anhydrous mgso4 is the desired product, what is the atom economy of this reaction?.
This problem is referring to an anhydrous salt that is derive from a hydrated Epson salt (magnesium sulfate hydrate) and the atom economy is required. However, not enough information is provided, yet we can use the attached file as a reference to provide a methodology of calculation.
To begin with, we need to calculate the [tex]x[/tex] which refers to the degree of hydration of the salt, so that we use the mass before and after heating the sample to figure out the grams and subsequently moles of water that are in there:
[tex]m_w=3.648g-1.782g=1.866g\\\\n_w=0.103molH_2O[/tex]
Next, since 1.782g corresponds to the anhydrous salt, we calculate the moles in such a amount:
[tex]1.782gMgSO_4*\frac{1molMgSO_4}{120.4gMgSO_4}=0.0148mol[/tex]
Then, we divide the moles of water by those of the anhydrous salt to calculte [tex]x[/tex]:
[tex]x=\frac{0.103mol}{0.0148mol} =6.96=7[/tex]
This means the formula of the hydrate is:
[tex]MgSO_4\ 7H_2O[/tex]
Finally, for the atom economy we just divide the molar mass of the anhydrous salt by that of the hydrate:
[tex]A.E=\frac{120.4g/mol}{246.47g/mol} *100\%\\\\A.E=48.8\%[/tex]

Use this picture to explain that an electrically charged object can attract an uncharged object without any contact. Your answer should be at least three sentences long.
Answer:
It is because the object that is charged attracts the uncharged because it is giving electrons and passing it on to the object. As shown in the image the balloon is attracting the paper that is not charged. Actually telling,the charged object will cause the uncharged object to become charged, with a positive charge on one side and a negative charge on the other side. This process is called induction.
Explanation: Pls Mark Brainliest
Answer:
Positive and negative charges
Explanation:
When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. In the figure, we can see that the ballon has charges which produces opposite charges in the paper which is uncharged.
