In the figure , if Q = 30 uC , q = 5.0 uC , and d = 30 cm , what is the magnitude of the electrostatic force on g?
lana [24]

Answer:

F =  k\frac{q_1q_1}{ {d}^{2} }  \\  = 9.0 \times  {10}^{9}  (N {m}^{2}  {C}^{ - 2}) \frac{30 \times  {10}^{ - 6} (C)5.0 \times {10}^{ - 6} (C)}{ {0.3}^{2} } N

Which combination of units can be used to express the magnetic field?
Zolol [24]

Answer:

The magnetic field unit in the International System is the tesla (T). A tesla is defined as the magnetic field that exerts a force of 1 N (newton) on a load of 1 C (coulomb) that moves at a speed of 1 m / s within the field and perpendicular to the field lines

Explanation:

Magnetic induction or magnetic flux density (B), is the magnetic flux that causes a diffusion charge in motion for each unit of normal area to the direction of the flow. It is also called the magnetic field strength.

The unit of magnetic flux density in the International System of Units is the tesla (T).

The tesla (symbol T), is the magnetic induction unit (or magnetic flux density) of the International System of Units (SI). It is defined as a uniform magnetic induction that, normally distributed over a surface of one square meter, produces through this surface a total magnetic flux of a weber.

<u>Equivalences: </u>

1 T = 1 Wb · m-2 = 1 kg · s-2 · A-1 = 1 kg · C-1 · s-1

A Tesla is also defined as the induction of a magnetic field that exerts a force of 1 N (newton) on a load of 1 C (coulomb) that moves at a speed of 1 m / s within the field and perpendicular to the lines of magnetic induction.

1 T = 1 N · s · m-1 · C-1

Basic Unit in the Cegesimal System of Units (CGS): Gauss (G)

A gauss (G) is a magnetic field unit of the Cegesimal System of Units (CGS). A gauss (G) is defined as a maxwell per square centimeter.

1 gauss = 1 maxwell / cm2

A gauss is equivalent to 10-4 tesla:

1 T = 10,000 G

The diagram shows changing wavelengths along the electromagnetic spectrum. Which labels belong in the areas marked Y and Z? Y: U
marshall27 [118]
Y: Radio 
Z: Gamma
because gamma has a higher frequency then radio, therefore the higher the frequency the shorter the wavelength

inn [45]

Answer:

D.

Explanation:

As you see, the graph INCREASES, which means it goes up. It is not going down, only rising.

If I'm wrong forgive me ;-;
