Answer:

Explanation: the explanation goes as follow;

  • If an equation is dimensionally correct, does this mean that the equation must be true?

answer: A dimensionally correct equation deosn't make the equation true. It is always possible to construct an arbitrary meaningless equation that satisfies the dimensional analysis. we can observe this in different physical quantities that have the same dimensional formula, by inserting a wrong physical parameter into an equation, it may turn out as dimensionally correct, but it wont have any physical meaning.

  • If an equation is not dimensionally correct, does this mean that the equation cannot be true?

answer:  A dimensionally incorrect equation necessarily implies that the equation is wrong.

  • How is dimension analysis used as a check on the plausibiity of derived equations and computations?

answer: dimensional analysis is a very strong tool that is used to check the trustworthiness of  a derived equation. It helps to compare the dimensions of the output variable from an equation against the true dimensions of the output variable. If both of them are not same, the equation/computation/derivation is incorrect.

  • How does this knowledge help you to understand and characterize particular phenomenon?

answer:  the knowledge of dimensional analysis helps in understanding which variables are necessary for defining a process.

How do solar panels work with conduction, convection and radiation?
Lady_Fox [76]

Answer:

<em>In the case of a solar thermal panel we are trying to heat above the ambient temperature so conduction and convection will work against us by taking heat from the panel to the out- side world. ... The sun (at 6000 C surface temperature) is hotter than the solar panel so the panel will get hot due to the solar radiation.</em>

An electric field of 1.27 kV/m and a magnetic field of 0.490 T act on a moving electron to produce no net force. If the fields a
lesantik [10]

Answer:

v = 2591.83 m/s

Explanation:

Given that,

The electric field is 1.27 kV/m and the magnetic field is 0.49 T. We need to find the electron's speed if the fields are perpendicular to each other. The magnetic force is balanced by the electric force such that,

qE=qvB\\\\v=\dfrac{E}{B}\\\\v=\dfrac{1.27\times 10^3}{0.49}\\\\v=2591.83\ m/s

So, the speed of the electron is 2591.83 m/s.
