Radio waves and microwaves are similar because they both have

Physics

tekilochka [14]2 years ago

The correct answer is

b. low frequencies and low energy.

In fact, microwaves and radio waves have frequency up to 10^{10}-10^{11} Hz, which are really low compared, for instance, to the frequency of gamma rays (10^{20} Hz). Moreover, the energy of an electromagnetic wave is directly proportional to its frequency:

E=hf

where h is the Planck constant and f the frequency; therefore, low frequency means also low energy.

If the center of mass passes outside the area of support of an object, what will happen to it?
defon

Answer:

If a vertical line extending down from an object's CG extends outside its area of support, the object will topple

Explanation:

We can understand better this situation using a diagram with the forces acting on it.

In the attached image we can see that when the gravity center is bouncing outside from the area of the pedestal, the object will be out of balance and will fall.

What is the change in length of a 1400. m steel, (12x10^-6)/(C0) , pipe for a temperature change of 250.0 degrees Celsius? Remem
8090 [49]

Answer:

\Delta L = 4.2 m

Explanation:

As per the formula of thermal expansion we know that

L = L_o(1 + \alpha\Delta T)

so here we will have

L_o = 1400 m

\alpha = 12 \times 10^{-6} per ^oC

\Delta T = 250 degree C

so here change in the length of the rod is given as

\Delta L = L - L_o

\Delta L = L_o \alpha \Delta T

\Delta L = 1400 (12 \times 10^{-6})(250)

\Delta L = 4.2 m
