What type of energy does a person experience when jumping on a trampoline?

Chemistry
1 answer:
Fofino [41]2 years ago
7 0

Answer:

Knetic

Explanation:

When you jump on a trampoline, your body has kinetic energy that changes over time. As you jump up and down, your kinetic energy increases and decreases with your velocity. Your kinetic energy is greatest, just before you hit the trampoline on the way down and when you leave the trampoline surface on the way up.

What is the ratio strength of 100 ml containing a 1:50 povidone iodine solution diluted to 1000 ml? (answer must be numeric; no
guapka [62]

We are given that:

100 mL total solution with 1:50 povidone iodine solution

 

This means that there is 1 mL of povidone iodine solution per 50 mL of total solution. Since we are given a total of 100 mL solution, therefore we have an initial amount of:

pure povidone iodine solution = 2 mL

 

This amount of pure povidone iodine solution is added or diluted (most perhaps with water) to make a total of 1000 mL total solution, therefore the new ratio is:

2:1000 povidone iodine solution

By dividing both sides by 2, this simplifies to

1:500 povidone iodine solution

 

Answer:

1:500

A sample of gas has a volume of 1.9L and a temperature of 21 degrees celsius. Heat is applied to the sample, leading to an incre
Mashutka [201]

Answer:

1.94 L

Explanation:

21°C = 21 +273 = 294 K

27°C = 27 + 273 = 300 K

T1/V1 = T2/V2

294 K/1.9 L = 300 K/x L

x = (1.9*300)/294 ≈ 1.94 L

Find the mass of 3.60x10^24 atoms of magnesium?
Arturiano [62]

Answer:

The answer to your question is 8.75 x 10 ²⁵ atoms of Magnesium

Explanation:

Data

Atomic mass of Magnesium = 24.31 g

Atoms of magnesium = 3.60 x 10²⁴

Process

Solve this porblem using a rule of three

             

           1 atom of Magnesium ---------------  24.31 g

           3.60 x 10²⁴                  ----------------    x

           x = (3.60 x 10²⁴ x 24.31) / 1

           x = 8.75 x 10 ²⁵ atoms

The equilibrium constant for the following equation:
Mkey [24]

From the calculation, the partial pressure of Cl2 is 1.98 atm. Option B

<h3>What is the equilibrium constant?</h3>

The term equilibrium constant refers to the value that shows us the extent to which reactants are converted into products. We know that the equilibrium constant can only be obtained by the use of the equilibrium partial pressures of each of the species.

Thus we have;

K = p PCl3 . pCl2/pPCl5

p PCl3 = partial pressure of PCl3

pCl2 = partial pressure of Cl2

pPCl5 = partial pressure of PCl5

K = equilibrium constant

Substituting values;

1.05 =  0.463 *  pCl2/0.875

 pCl2 = 1.05  * 0.875/0.463

pCl2 = 1.98 atm
