Jaden places potatoes with a mass of 0.55 kilograms on a grocer's scale. The spring is displaced by 1.2 centimeters. He then places some onions on the scale that displace the spring by 0.67 cm. What is the mass of the onions (1 kg=9.8 N)? 5.39 kg 3.01 kg 0.67 kg 0.31 kg

.31 kg

Step-by-step explanation:

F=kx

F = the force of the spring

k = the spring constant

x = the spring displacement (stretch or compression)

we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F

let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N

so 5.39=k(1.2 centimeters)

Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)

divide 5.39 by .012 to get 449.17

our k is 449.17

Now for our problem, we are going to find the mass.  

Do this by putting what we already know into the problem.

F=449.17(.67 centimeters)

Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)

This will result in F=3.01 but the problem is asking for mass, not force.

Use the formula 9.8(kg)=F

9.8(kg)=3.01

kg=.31

solution: .31 kg

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
