Explanation:
As wine and cheese are consumed together,it means that they both are complimentary goods.
As per law of demand,the fall in price of a complimentary good would increase the demand and shift the demand curve of the other to the right.
The equilibrium quantity of cheese would increase and shift to right when the price of wine falls.
Answer:
C. Add all the force vectors
Explanation:
The net force acting on an object is the vector sum of all the forces on the object.
Remember, Newton's first law tells us a body at rest will remain at rest or that in uniform motion will continue in motion unless acted by unbalanced forces.These unbalanced forces act in all direction towards the body thus to get the net force you require a summation of all these force with respect to their magnitudes and directions.
For example a force of 3N towards the East direction acting on a body and another force of 2N towards the West direction on the same body will generate a net force of 1N towards the East direction.
Answer:
D
Explanation:
She says that the object of the experiment is to see how far the string stretches given a mass attached to the string.
The only thing that is at issue is either the mass or the amount the string stretches.
Nothing else matters.
The dependent variable therefore is the amount the string stretches. So the last choice is the answer.
Answer: 0.683
Explanation: The relationship between a car moving along a curve and the frictional force is given below as
us×g = v²/r
Where us = coefficient of static friction =?, g = acceleration due to gravity = 9.8 m/s², v = 22.4 m/s and r = 75m
By substituting the parameters, we have that
us×9.8 = 22.4²/ 75
us ×9.8 = 501.76/75
us ×9.8 = 6.690
us = 6.690/9.8 = 0.683
Answer:

Explanation:
<u>Densidad</u>
La densidad de una masa m que ocupa un volumen v se define como:

Tenemos que una masa de 80 gr hace que un volumen de agua se desplace desde 60 cm3 hasta 75 cm3, es decir, el volumen propio de la masa es m = 75 - 60 = 15 cm3.
Con esta información se calcula la densidad:
