How does a pulley make work easier?

2 answers:

8 0

Pulleys are powerful simple machines.they can change the direction of a force which can make it much easier for us to make something.

Example:
If we want to lift something that weights 10 kilograms one meter high we can lift it straight up or we can use a pulley se we can pull down on one end to lift the object up

Krebs Cycle experiment: if you want to increase the rate of the succinate forming fumarate, what could you do to the experiment?

Sergio [31]

To increase the rate of the succinate forming fumarate you can increase the ATP and the enzyme that catalyzes this reaction

The Krebs cycle, also known as the citric acid cycle comprises a set of chemical reactions that are essential for organisms to obtain energy.

One of the steps in the cycle involves the use of succinate with a chemical formula of C4H6O4 to form fumarate or C4H4O4. This means in this reaction it is necessary to remove 2 hydrogen atoms.

This process requires two main factors:

ATP or energy the cell uses to carry out the reaction
Succinate dehydrogenase or the enzyme that removes the hydrogen atoms

Based on this, the reaction can be faster if there is more succinate dehydrogenase or if the energy increases.

To solve this problem we will start from the definition of the decibels which refers to the log relationship of the intensities, mathematically each decibel of the people can be described as follows

$dB_1 = 10log(\frac{I_1}{I_o})$

$dB_2 = 10log(\frac{I_2}{I_o})$

$dB_1 - dB_2 = 10log(\frac{I_1}{I_2})$

$\frac{67-45}{10} = log(\frac{I_1}{I_2})$

$log(\frac{I_1}{I_2}) = \frac{11}{5}$

For properties of the logarithm then we have that,

$\frac{I_1}{I_2} = 10^{11/5}$

$\frac{I_1}{I_2} = 158.48$

We have the relation

$\frac{r_2^2}{r_1^2} = 158.48$

$\frac{r_2}{r_1} = \sqrt{158.48}$

$\frac{r_2}{r_1} = 12.58$

If the current in each wire is the same, which wire produces the strongest magnetic field?

lions [1.4K]

Answer: option 4: A wire that is 2-mm thick and coiled.

Explanation:

The current in each wire is same. The magnetic field due to a current carrying wire increases if the wire is coiled with the more number of turns. A thick wire would cause low resistance to the current. Hence, a 2-mm thick wire which is coiled would produce the strongest magnetic field.
