Answer:
decrease their prices
Explanation:
If we see demand curve then we can observe that demand for good decreases when price increases and demand for good increases when price decreases.
We also know intuitively that customer are price sensitive. That is their buying behavior changes with price of goods, Consumers prefer lower priced good.
So, if business owners want to increase demand for their goods and services
they should decrease their prices.

A lens with f= 10.0 cm is held
45.0 cm from an object. What is
the image distance?
(Unit = cm)
it is not 12 cm.
Answer:
8.2 cm
Explanation:
1/f = 1/so + 1/si
1/10 = 1/45 + 1/si
1/si = 1/10 - 1/45
1/si = 9/90 - 2/90
1/si = 7/90
si = 90/7 = 12.86 cm.
since you said that the answer was not 12 them the lens must be concave with negative (minus) focal length
1/f = 1/so + 1/si
- 1/10 = 1/45 + 1/si
1/si = - 1/10 - 1/45
1/si = -9/90 - 2/90
1/si = -11/90
si = -90/11 = - 8.2 cm
- (read: minus or negative sign) indicates the image is in the same side of the object
hope its true and can help you
Answer:
1/f = 1/u + 1/v
f=10cm
u=45cm
v=? (Image distance)
1/v = 1/f - 1/u
1/v = 1/10 - 1/45
1/v = (9-2)÷ 90
1/v = 7/90
:. v = 90/7
v=12.86cm(image distance)

explain why the statement “Dropped objects fall toward the ground" is a law and not a theory
The statement is a law because it accurately describes EVERY observation. No contradiction has ever been observed that would disprove it, or even cast doubt on it.
(Wellll ... at least, no contradiction that wasn't immediately and easily explainable, like dropping a helium balloon, or a sheet of paper in a high wind.)
The statement is legal because it accurately describes all that is seen. No controversy has ever arisen to disprove it or cause it to doubt.
What is gravity?The force of gravity is the force that the planet or another body of gravity absorbs. Gravity holds all the planets in orbit around the sun.
What causes gravity?The greater the size of the two objects and the shorter the distance between them, the stronger the gravitational force. We also know that gravity can work in a complex system with several components.

How does the value of the electrostatic force vary with the value (how many) of the charges?
Answer:
Electrostatic force is directly proportional to the amount of charge on each body under consideration.
Electrostatic force increases with increase in charge.
Electrostatic force decreases with decrease in charge.
Explanation:
Electrostatic force is the force between 2 charges which can be explained by the Coulomb's Law:
F= K (q₁)(q₂)/r²
Where
F= Electrostatic Force
K = Constant of Proportionality
(q₁) and (q₂) = Amount of charge on each body
r = Distance between two bodies carrying charge
If the value of (q₁) or (q₂) is increased considering the other factors remain constant, the value of F will also increase.
And vice versa.

A vector points 12.0 units along the x-axis, and 9.00 units along the y-axis. Find the direction of the vector
The resultant points somewhere between the positive x and y axes.
The angle it makes with the x-axis has a tangent of (9/12) = 0.75 .
That angle is 36.9°, rounded to the nearest tenth of a degree.
So the resultant vector points up and to the right, 36.9° above the x-axis.

Which of the following best describes how the Federal Reserve Bank helps
banks during a bank run?
A. The Federal Reserve Bank acts as an insurance company that
pays customers if their bank fails.
B. The Federal Reserve Bank regulates exchanges to prevent the
demand for withdrawals from rising above the required reserve
ratio.
C. The Federal Reserve Bank has the power to take over a private
bank if customers demand too many withdrawals.
D. The Federal Reserve Bank can provide a short-term loan to banks
to prevent them from running out of money.
Answer:
D. The Federal Reserve Bank can provide a short-term loan to banks
to prevent them from running out of money.
Explanation:
A bank run occurs when a large number of depositors withdraw their deposits simultaneously from a bank.
As the number of withdraws increases, the available cash in the bank decreases until a point that the bank can't give depositors their money.
In these situations, The Federal Reserve Bank acts as a lender of last resort that helps to reinforce the effect of deposit insurance, and to reassure bank customers that they will not lose their money.
What is the average velocity of atoms in 1.00 mol of neon (a monatomic gas) at 465 K? For m, use 0.0202 kg.
Answer: 757m/s
Explanation:
Given the following :
Mole of neon gas = 1.00 mol
Temperature = 465k
Mass = 0.0202kg
Using the ideal gas equation. For calculating the average kinetic energy molecule :
0.5(mv^2) = 3/2 nRt
Where ;
M = mass, V = volume. R = gas constant(8.31 jK-1 mol-1, t = temperature in Kelvin, n = number of moles
Plugging our values
0.5(0.0202 × v^2) = 3/2 (1 × 8.31 × 465)
0.0101 v^2 = 5796.225
v^2 = 5796.225 / 0.0101
v^2 = 573883.66
v = √573883.66
v = 757.55109m/s
v = 757m/s

9. A weather satellite is launched from the ground and placed in orbit six times farther away from the earth's centre. The gravitational field experienced by the satellite in orbit is the field that it experienced on the ground?
a Six times
b. One sixth of
c. Thirty-six times
d. One thirty-sixth of
Answer: d
One thirty-sixth of
Explanation: Gravitational field or gravitational field strength obeys the inverse square law. The gravitational field is inversely proportional to the square of the earth distance. That is,
g = Gm/r^2
Where r = distance.
If weather satellite is placed in orbit six times farther away from the earth's centre, gravitational field will be one thirty-sixth of its initial value.
Therefore, the gravitational field experienced by the satellite in orbit is one thirty-sixth of the field that it experienced on the ground.

Matthew is looking at two different atoms. One has 8 protons and 10 neutrons. The other substance has 8 protons and 12 neutrons. Are these the same element? Why or why not?
Answer:
They are the same element.
Explanation:
Atom >>>>> Proton >>>> Neutron
A >>>>>>>> 8 >>>>>>>>> 10
B >>>>>>>> 8 >>>>>>>>> 12
From the table above we can see that both atoms have the same proton number.
Therefore, they are the same element because they have the same proton number which means that they have the same atomic number. The element in this case is existing as an isotope in that the atoms have the same proton number but different neutron number.
Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.
Answer:
D
Explanation:
Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)
Answer:
Explanation: D
Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.
A is wrong because that tells you perimeter
B is wrong because that tells you the midpoint
C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors
D is correct, this perfectly explains the distance formula
