Answer:

gravity is the invisible force that attracts us the the earth\

1.normal force 2.frictional force 3. spring forces

flowing electrons produce a magnetic field

unbalanced forces are not equal they always cause changes in the moving object like the direction . balanced forces are equal and cause no changes

The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system the meter kilogram second (s), kelvin the ampere , the mole and the candela.

A 10-µf capacitor is plugged into a 110 v-rms 60-hz voltage source. what is the rms value of the current through the capacitor?

ValentinkaMS [17]

The rms value of current is0.414A, and the maximum value of current is 0.585A.

To find the answer, we have to study about the capacitive reactance.

<h3>How to find the rms and maximum value of current?</h3>

We have the expression for rms value of current as,

$I_{rms}=\frac{V_{rms}}{X_c}$

where; Xc is the capacitive reactance of the circuit.

We have the capacitive reactance as,

$X_c=\frac{1}{2\pi fC} =\frac{1}{2\pi *60*10*10^{-6}} =265.39 Ohm$

Thus, the value of rms current will be,

$I_{rms}=\frac{110}{265.39} =0.414A$

Thus, the maximum value of current will be,

$I_0=\sqrt{2}*I_{rms} =0.585A$

Thus, we can conclude that, the rms value of current is0.414A, and the maximum value of current is 0.585A.

Two equally charged spheres of mass 1.00 g are placed 2.00 cm apart. When released, the initial acceleration of each sphere is 2

shusha [124]

Answer:

$q = 0.107 \mu C$

Explanation:

As we know that net force is given by

$F = ma$

here we have

m = 1.00 g = 0.001 kg

also we know that acceleration is given as

$a = 256 m/s^2$

now force is given as

$F = 0.001(256) = 0.256 N$

now by the formula of force we know that

$F = \frac{kq_1q_2}{r^2}$

$0.256 = \frac{(9\times 10^9)q^2}{(0.02)^2}$

now for solving charge we have

$q = 0.107 \mu C$

Anni [7]

Answer:

analyze, assess or interpret an historical event, era, or phenomenon,.

Explanation:

Secondary sources are works that analyze, assess or interpret an historical event, era, or phenomenon, generally utilizing primary sources to do so. Secondary sources often offer a review or a critique. Secondary sources can include books, journal articles, speeches, reviews, research reports, and more.

What type of wave is shown above?

Basile [38]

B. longitudinal wave

Explanation:

Longitudinal waves are made up of regions of rarefaction and compression. They are waves that are propagated parallel to their source.

During wave compression, molecules are pressed together and are closer to each other.
Rarefaction is where molecules are farther apart and are distant.
In longitudinal waves, the source is parallel to the wave propagation.
Transverse waves are perpendicular to their source.
Electromagnetic consists of vibrations in both perpendicular direction.
Surface waves are seismic waves that are made up of both transverse and longitudinal components.
