Answer:

11,890

Explanation:

First we need to know what is considered a significant figure.

A significant figure is a value that is not a zero at the start OR end of a value.

Which means, the 0 in the value of 90 or 0.363 are not considered a significant figure.

The 0 in the value of 3056 is considered a significant figure.

So from the table, we can deduce:

0.275 has 3 significant figures

750 has 2 significant figures

$10.4 \times {10}^{5} = 1040000$

has 3 significant figures.

11,890 has 4 significant figures.

320,050 has 5 significant figures.

So from the above, we can already see the answer.

Find the period of the leg of a man who is 1.83 m in height with a mass of 67 kg. The moment of inertia of a cylinder rotating a

Lady bird [3.3K]

Answer:

1.54 s

Explanation:

Considering that the legs constitute 16% of the total weight of the man then mass, $m= \frac {16}{100}\times 67=10.72 Kg$

The legs also constitute 48% of his height hence $H=\frac {48}{100}\times 1.83=0.8784 m$

The moment of inertia of a cylinder rotating about a perpendicular axis at one end is $\frac {ml^{2}}{3}$ hence $I=\frac {10.72\times 0.8784^{2}}{3}=2.757135974Kg.m^{2}$

We also know that the period is given by $2\pi \sqrt{\frac {I}{mgh}}$

Here, h=0.5H= 0.5*0.8784=0.4392 m

Taking g as 9.81 kg/m2 then

$T= 2\pi \sqrt{\frac {2.757135974}{10.72\times 9.81\times 0.4392}}\\=1.535132615 s\\\boxed{\approx 1.54 s}$

7. Mrs. Everhart developed the theory that all bulldogs are great pets. After all her bulldog Meatball is a

Advocard [28]

Answer: No.

Explanation:

A scientific theory is an explanation of some aspect of the natural world that can be tested several times, and follows the scientific method. And, when possible, theories are tested with experiments.

Now, a scientific theory must meet some criteria, and one of those is that it must be supported by several (and independent) strands of evidence.

In this case, we have only one, Meatball, and it is not enough, then it can not be a scientific theory.

Where is potential energy in food stored

AlexFokin [52]

The potential energy is stored in the chemical bonds of the food. When those bonds break up during the metabolic processes, the energy is released. After that, that energy is stored in the Adenosine Triphosphate bonds aka ATP. The simplest way to think is to think of food as the tightly bound atoms. When the chemical bonds between those atoms break, the stored energy in that food is released.

What property or properties of a wave determine it's speed?

mash [69]

The properties of the wave don't determine its speed. The properties of the medium do. You can FIND the speed by measuring the wave's frequency and wavelength.
