Answer:

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz

Suppose a thin conducting wire connects two conducting spheres. A negatively charged rod is brought near one of the spheres, the

dangina [55]

Answer:

a. The spheres will attract each other.

Explanation:

When two conducting spheres are connected by a conducting wire and a negatively charged rod is brought near it then this will induce opposite (positive) charge at the nearest point on the sphere and by the conservation of charges there will also be equal amount of negative charge on the farthest end of this conducting system this is called induced polarization.

When the conducting wire which joins them is cut while the charged rod is still in proximity to of one of the metallic sphere then there will be physical separation of the two equal and unlike charges on the spheres which will not get any path to flow back and neutralize.

Hence the two spheres will experience some amount of electrostatic force between them.

An underwater observation room at an offshore oil rig has a 50-cm diameter window. The center of the window is located at a dept

Murljashka [212]

Answer:

$F = 3.17 \times 10^4 N$

Part b)

Force will act at the center of the window

Explanation:

Pressure at the centre of the window is given as

$P = P_o + \rho gH$

here we know that

$P_o = 1.01 \times 10^5 Pascal$

$\rho = 1.028 \times 10^3 kg/m^3$

g = 9.81 m/s/s

H = 6 m

$P = (1.01\times 10^5) + (1.028\times 10^3)(9.81)(6)$

$P = 1.615\times 10^5 Pa$

now the area of the window is given as

$A = \pi r^2$

$A = \pi(0.25)^2 = 0.196 m^2$

Now force on the window is given as

$F = 0.196(1.615\times 10^5) = 3.17\times 10^4 N$

Part b)

Force will act at the center of the window

Part a which of the following statements are true concerning electromagnetic induction?

maksim [4K]

I had to look for the options and here is my answer:

Based on the actual options attached to this question, the statements that are considered true about electromagnetic induction are the following:
-It is possible to induce a current in a closed loop of wire without the aid of a power supply or battery.
-It is possible to induce a current in a closed loop of wire by changing the strength of a magnetic field enclosed by the wire.
-It is possible to induce a current in a closed loop of wire by change the orientation of a magnetic field enclosed by the wire.
-It is possible to induce a current in a closed loop of wire located in a uniform magnetic field by either increasing or decreasing the <span>area enclosed by the loop.</span>
