The number of boxes were produced willl be 7.57.n stands for the no of boxes.
<h3>What is volume?</h3>
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
The volume of the cylindrical metal bar;
V₁=πr²h
V₁=3.4 × 7² × 484 cm
V₁=80,634.4 cm³
The one side of the box is,220mm(22 cm)
V₂ = a³
V₂ = (22)³
V₂ = 10,648 cm³
The no of boxes is found as;
n = V₁/V₂
n=80,634.4 cm³/10,648 cm³
n=7.57
Hence, the number of boxes were produced willl be 7.57

Answer:
The sequence is A,B,H,B,F
Explanation:
- The Standard International unit is Kilogram (kg) and the mass of a body can also be expressed in gram (g).
- Heat is a form of energy and the unit for energy is joule (J), thus the unit of heat is also joule (J).
- Density is mass per unit volume where the unit of mass is gram (g) and the unit of volume can be taken as milli-liter (mL). Thus g/mL is the unit of density.
- The unit of energy is joule (J).
- Molarity is number of solute in mol dissolved in 1 liter of solution. Thus mol/L is the the unit of molarity.
Answer:
Explanation:
Orbital radius of satellite A , Ra = 6370 + 6370 = 12740 km
Orbital radius of satellite B , Rb = 6370 + 19110 = 25480 km
Orbital potential energy of a satellite = - GMm / r where G is gravitational constant , M is mass of the earth and m is mass of the satellite
Orbital potential energy of a satellite A = - GMm / Ra
Orbital potential energy of a satellite B = - GMm / Rb
PE of satellite B /PE of satellite A
= Ra / Rb
= 12740 / 25480
= 1 / 2
b ) Kinetic energy of a satellite is half the potential energy with positive value , so ratio of their kinetic energy will also be same
KE of satellite B /KE of satellite A
= 1 / 2
c ) Total energy will be as follows
Total energy = - PE + KE
- P E + PE/2
= - PE /2
Total energy of satellite B / Total energy of A
= 1 / 2
Satellite B will have greater total energy because its negative value is less.
Answer:
G.) The number atoms of that element in the molecule
Explanation:
F is incorrect because the coefficient represents the amount of one type of molecule, not the subscript
G is correct because subscripts represent how many atoms of that element are present in that single molecule
H is incorrect because energy is not represented in this simple type of equation
J is incorrect because it doesn't even make sense
