Answer:The correct answer is' more mass'.

Explanation:

Gravity is the force by which planet or any other body attracts an object to wards its center.It is also known force of gravitation which exist in between the object with non zero mass.

The formula of gravitational force is given by:

$F=G\frac{Mm}{r^2}$

M, m = mass of two different objects.

r = distance between the two objects

G = gravitational constant

F = Gravitational force

From the formula we can say that gravitational force or gravity is directly proportional to mass of an object. That is more the mass of an object more will be the force of gravity.

Gravity can be considered an acceleration constant that works on all mass. The greater the mass the greater will the gravity affect the object of interest.

While burning coal and charcoal, you notice that coal releases more heat than charcoal. That means that the... 1. elastic energy

Dafna11 [192]

Answer:

3). Chemical potential energy

1). lower in charcoal than in coal.

Explanation:

Chemical potential energy is defined as the energy that can be absorbed or stored in a substance's chemical bonds. It can be released when there is a change in the number of particles of the substance.

As per the question, coal releases more heat than charcoal because 'the chemical potential energy of charcoal is lower than the coal' and hence, the latter would release more heat on burning i.e. the energy that was absorbed in the chemical bonds of the substance. Hence, option 3 and 1 are the correct answers.

Calcium reacts with oxygen to form calcium oxide. The chemical equation for this reaction is Ca + O2→CaO . What is the product,

iris [78.8K]

Answer:

A. CaO

Explanation:

Reactant are the species that take part in and also undergoes the reaction to form species which are known as products.

Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.

Thus, in the reaction shown below:-

$Ca+O_2\rightarrow CaO$

Thus, The product of the reaction is:- CaO

Zn-64 = 48.63%

sladkih [1.3K]

Answer:

A = 65.46 u

Explanation:

Given that,

The composition of zinc is as follows :

Zn-64 = 48.63%

Zn-66 = 27.90%

Zn-67 = 4.10%

Zn-68 = 18.75%

Zn-70 = .62%

We need to find the average atomic mass of the given element. It can be solved as follows :

$A=\dfrac{48.63\times 64+27.90\times 66+4.1\times 67+18.75\times 68+0.62\times 70}{100}\\A=65.46\ u$

So, the average atomic mass of zinc is 65.46 u.

A fruit drink concentrate is 15% water. how many liters of pure water should be added to 12l of concentrates to produce a mixtur

harkovskaia [24]

1 liter of drink contain water = 15% 12l of drink contain water = 15 % 12l of drink contain water at 15% = 1.8l 12l of drink contain water at 50% = 6l Water to add in 15% water drink = 6l â€“ 1.8l = 4.2l After adding 4.2l of water in 12l 15% water drink, we get 50% water drink.

The average osmotic pressure of ocean water is 28 atm corresponding to a concentration of 0.50m solutes. what is the approximate

RideAnS [48]

Answer : 0.125 M

Explanation : The definition of osmotic pressure is "the pressure can be applied on a pure solvent to prevent it passing into a given solution by osmosis".

So according to this definition, osmotic pressure can be called as directly proportional to the concentration of the solution and hence the pressure can also be directly proportional to the concentration.

Hence, if pressure is getting decreased from 28 to 7 it means it got decreased by 4 times;
28 / 7 = 4 that means;

So the concentration will be also decreased by 4 times so, 0.50 / 4 = 0.125 M
