Conservation of momentum

Physics
1 answer:
hammer [34]3 years ago
5 0

That's a good one, and there's more to this than meets the eye.

Mass and velocity don't have to be conserved, but energy and
momentum both do !

What is the amount of thermal energy that can be stored in an object depends on?
77julia77 [94]
Thermal energy is the total energy of all the molecules in an object. The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter).

In electronics, the formula V = IR is called Ohm's Law. It gives the relationship in a circuit between the voltage V (in volts),
Tomtit [17]

Answer:

3+2i ohm.

Explanation:

Here we have a complex number operation. According to Ohm's law V=I*R, so:

R=\frac{V}{I}\\\\R=\frac{21+i}{5-3i}

we need to remove the complex number on the denominator, so we have to multiply by its complement on both side

R=\frac{21+i}{5-3i}*\frac{5+3i}{5+3i}

that gives us:

R=\frac{102+68i}{34}=3+2i

The blank is an estimating technique which requires knowledge and experience
I am Lyosha [343]

The ratio method exists as  an estimating technique which requires knowledge and experience,

<h3>What is meant by ratio method?</h3>
  • Ratio technique: This method uses a basic project attribute, like size in square meters or the number of software features, and the cost per meter or feature to project the overall cost and length of the project.
  • Ratio analysis in project management can measure how effectively resources are being managed and how efficiently the project is running. The balance sheet and income statement of an organization are typically where financial ratios in the corporate environment are derived.
  • A measure of the relationship between a proposed project's relative costs and benefits, expressed in monetary or qualitative terms, is the benefit-cost ratio (BCR). The expectation is that a project with a BCR of greater than 1.0 will provide a firm and its investors with a positive net present value.

Hence, The ratio method exists as  an estimating technique which requires knowledge and experience,

Longer wavelengths will have ________ frequencies, and shorter wavelengths will have ________ frequencies.
MakcuM [25]
Within a single medium, the product of (wavelength) x (frequency)
is always the same number, for all waves.  (It's the wave-speed.)

This means that longer wavelengths must have lower frequencies,
and shorter wavelengths must have higher frequencies, in order for
the product to always come out to be the same.
