Precautions to be taken for the displacement method

Physics
1 answer:
finlep [7]3 years ago
8 0

Volume by Displacement. The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.

The following precautions should be taken very observantly:-

The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided. Any bubbles within leads to wrong measurements.

What are radioactive isotopes?
melisa1 [442]

Answer:

<em><u>R</u></em><em><u>adioactive isotope</u></em> , also called radioisotope,

radionuclide, or radioactive nuclide, any of

several species of the same chemical element

with different masses whose nuclei are unstable

and dissipate excess energy by spontaneously

emitting radiation in the form of alpha , beta , and

gamma rays .

A brief treatment of radioactive isotopes follows.

For full treatment, see isotope: <u>Radioactive</u>

<u>Radioactiveisotopes.</u>

Every chemical element has one or more

radioactive isotopes. For example, hydrogen, the

lightest element, has three isotopes with mass

numbers 1, 2, and 3. Only hydrogen-3 (tritium ),

however, is a radioactive isotope , the other two

being stable. More than 1,000 radioactive

isotopes of the various elements are known.

Approximately 50 of these are found in nature;

the rest are produced artificially as the direct

products of nuclear reactions or indirectly as the

radioactive descendants of these products.

Radioactive isotopes have many useful

applications. In medicine , for example, cobalt -60

is extensively employed as a radiation source to

arrest the development of cancer. Other

radioactive isotopes are used as tracers for

diagnostic purposes as well as in research on

metabolic processes. When a radioactive isotope

is added in small amounts to comparatively large

quantities of the stable element, it behaves

exactly the same as the ordinary isotope

chemically; it can, however, be traced with a

Geiger counter or other detection device.

Iodine -131 has proved effective in treating

hyperthyroidism. Another medically important

radioactive isotope is carbon-14, which is used in

a breath test to detect the ulcer-causing bacteria

Heliobacter pylori .

What is the force of gravity between Earth (mass = 6.0 × 1024 kilograms) and Jupiter (mass = 1.901 × 1027 kilograms)? The distan
svlad2 [7]

Answer:

1.352 × 1018 newtons

Explanation:

The force of gravity between the two planets is given by:

F=G\frac{m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} Nm^2 kg^{-2} is the gravitational constant

m_1 = 6.0\cdot 10^{24} kg is the mass of the Earth

m_2 = 1.901 \cdot 10^{27} kg is the mass of Jupiter

r=7.5\cdot 10^{11} m is the distance between the two planets

Substituting all the numbers into the equation, we find:

F=(6.67\cdot 10^{-11}) \frac{(6.0\cdot 10^{24})(1.901\cdot 10^{27})}{(7.5\cdot 10^{11})^2}=1.352\cdot 10^{18} N
