They use x-rays to diagnose broken bones

Answer:

X-Rays

Explanation:

X-Rays are most widely used to diagnose broken bones without making an incision in the body. X Rays are part of the EM spectrum having a wave length in the range of 0.01 to 10 nanometers. They have a property of traversing through thick objects without being much absorbed or scattered, thus making it very useful for such procedure.

In a closed system, as kinetic energy increases, what happens to potential energy?

kupik [55]

<h2>Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.</h2>

You have a battery marked " 6.00 V 6.00 V ." When you draw a current of 0.383 A 0.383 A from it, the potential difference betwee

Archy [21]

Answer:

V = 4.81 V

Explanation:

As the potential difference between the battery terminals, is less than the rated value of the battery, this means that there is some loss in the internal resistance of the battery.
We can calculate this loss, applying Ohm's law to the internal resistance, as follows:

$V_{rint} = I* r_{int}$

The value of the potential difference between the terminals of the battery, is just the voltage of the battery, minus the loss in the internal resistance, as follows:

$V = V_{b} - V_{rint} = 5.03 V = 6.0 V - 0.383 A* r_{int}$

We can solve for rint, as follows:

$r_{int} = \frac{V_{b}-V}{I} =\frac{6.0V-5.03V}{0.383A} = 2.53 \Omega$

When the circuit draws from battery a current I of 0.469A, we can find the potential difference between the terminals of the battery, as follows:

$V = V_{b} - V_{rint} = 6.0 V - 0.469 A* 2.53 \Omega= 6.0 V - 1.19 V = 4.81 V$

As the current draw is larger, the loss in the internal resistance will be larger too, so the potential difference between the terminals of the battery will be lower.

Convert 1erg into joule by dimensional method

Valentin [98]

Answer:

1 * 10^-7 [J]

Explanation:

To solve this problem we must use dimensional analysis.

1 ergos [erg] is equal to 1 * 10^-7 Joules [J]

$1[erg]*\frac{1*10^{-7} }{1}*[\frac{J}{erg} ] \\= 1*10^{-7}[J]$

Define thermodynamics ???

BartSMP [9]

Answer:

The term thermodynamics comes from the Greek words therme (heat) and dynamis (force)

Explanation:

Thermodynamics can be defined as the science of energy. Thought everything the world has an idea of what energy is, it's hard to define it precisely.

Energy can be considered as the ability to cause change.

The term thermodynamics comes from the Greek words therme (heat) and dynamis (force), which corresponds to the most descriptive of the first efforts to convert heat into energy. At present, the concept is interpret broadly to include Energy Aspects and their transformations, including power generation, cooling and relationships among the properties of matter.
