Answer:

Scientists develop new technology, and then engineers use it to solve design problems. Engineers make a new discovery about nature, and then scientists do experiments to verify it.

Explanation

The capacitance of the capacitor is 1.7 * 10^-4 F. The capacitance will increase when the voltage is increased.

If we hold the capacitance constant, a higher voltage applied to the capacitor will result in a greater amount of electrical charge stored on the capacitor. Conversely, if we hold the voltage constant, a capacitor with a higher capacitance will be able to store more electrical charge. In other words, the capacitance and the voltage are directly proportional to the amount of electrical charge that can be stored on a capacitor.

We know that;

q = CV

C = q/V

C =  0.0024 C/12 V

Considering the Coulomb's Law, the force between the two ballons is 9.216×10⁻⁸ N.

Charged bodies experience a force of attraction or repulsion on approach.

From Coulomb's Law it is possible to predict what the electrostatic force of attraction or repulsion between two particles will be according to their electric charge and the distance between them.

From Coulomb's Law, the electric force with which two point charges at rest attract or repel each other is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them:

\(F=k\frac{Qq}{d^{2} }\)

where:

The force is attractive if the charges are of opposite sign and repulsive if they are of the same sign.

In this case, you know that two balloons have a negative charge of 1.6×10⁻¹⁰ C and the balloons are 0.05 m apart.

Replacing in the Coulomb's Law, you get:

\(F=9x10^{9} \frac{Nm^{2} }{C^{2} } \frac{(-1.6x10^{-10} C)x(-1.6x10^{-10} C)}{(0.05 m)^{2} }\)

Solving:

\(F=9x10^{9} \frac{Nm^{2} }{C^{2} } \frac{2.56x10^{-20} C^{2} }{(0.05 m)^{2} }\)

\(F=9x10^{9} \frac{Nm^{2} }{C^{2} } 1.024x10^{-17}\frac{ C^{2} }{m^{2} }\)

F= 9.216×10⁻⁸ N

Finally, the force between the two ballons is 9.216×10⁻⁸ N.

The answer is A. velocity .

Velocity is a vector quantity because it need magnitude as well as direction to be defined.

a. The equivalent resistance in series is 14.92 µΩ

b. The equivalent resistance in parallel is 2.58 µΩ

There are two types of equivalent resistance

The equivalent resistance in series is 14.92 µΩ

For a series circuit of two resistors R₁ and R₂, the equivalent resistance in series is R = R₁ + R₂

Since R₁ = 3.32 µΩ and R₂ = 11.6 µΩ

So, R = R₁ + R₂

R = 3.32 µΩ + 11.6 µΩ

R = 14.92 µΩ

So, the equivalent resistance in series is 14.92 µΩ

The equivalent resistance in parallel is 2.58 µΩ

For a series circuit of two resistors R₁ and R₂, the equivalent resistance in parallel is thus 1/R = 1/R₁ + 1/R₂.

Thus R = R₁R₂/(R₁ + R₂)

Since R₁ = 3.32 µΩ and R₂ = 11.6 µΩ

So, R = R₁R₂/(R₁ + R₂)

R = 3.32 µΩ × 11.6 µΩ/(3.32 µΩ + 11.6 µΩ)

R = 38.512µΩ²/14.92 µΩ

R = 2.58µΩ

Explanation:

A capacitor is a device that stores electrical energy in an electric field. It is made up of two conductor plates separated by a dielectric. It stores electrical charges which then produces a potential difference between the plates.

The equivalent capacitance for capacitors in series is given as:

\(\frac{1}{C_{eq}}=\frac{1}{C_1} +\frac{1}{C_2}+\frac{1}{C_3} \\ \\\frac{1}{C_{eq}}=\frac{1}{10.4} +\frac{1}{20}+\frac{1}{29.5}\\ \\C_{eq}=5.55\ \mu F\)

\(The\ total\ charge\ stored(Q)\ is:\\\\Q=C_{eq}V\\\\Q=5.55*10^{-6}F*125\ V=694 \mu C\)

The potential difference on each capacitor is:

\(V_1=\frac{Q}{C_1}=\frac{694\mu C}{10.4\mu F} =66.75\ V\\\\V_2=\frac{Q}{C_2}=\frac{694\mu C}{20\mu F} =34.71\ V\\\\V_3=\frac{Q}{C_3}=\frac{694\mu C}{29.5\mu F} =23.53\ V\)

Answer:

(a) \(\vec F_{\parallel} = -\frac{102}{13}\,i-\frac{103}{13}\,j\) , (b) \(\vec F_{\perp} = \frac{102}{13}\,i -\frac{68}{13}\,j\), (c) \(W = -51\)

Explanation:

The statement is incomplete:

The force on an object is \(\vec F = -17\,j\). For the vector \(\vec v = 2\,i +3\,j\). Find: (a) The component of \(\vec F\) parallel to \(\vec v\), (b) The component of \(\vec F\) perpendicular to \(\vec v\), and (c) The work \(W\), done by force \(\vec F\) through displacement \(\vec v\).

(a) The component of \(\vec F\) parallel to \(\vec v\) is determined by the following expression:

\(\vec F_{\parallel} = (\vec F \bullet \hat {v} )\cdot \hat{v}\)

Where \(\hat{v}\) is the unit vector of \(\vec v\), which is determined by the following expression:

\(\hat{v} = \frac{\vec v}{\|\vec v \|}\)

Where \(\|\vec v\|\) is the norm of \(\vec v\), whose value can be found by Pythagorean Theorem.

Then, if \(\vec F = -17\,j\) and \(\vec v = 2\,i +3\,j\), then:

\(\|\vec v\| =\sqrt{2^{2}+3^{3}}\)

\(\|\vec v\|=\sqrt{13}\)

\(\hat{v} = \frac{1}{\sqrt{13}} \cdot(2\,i + 3\,j)\)

\(\hat{v} = \frac{2}{\sqrt{13}}\,i+ \frac{3}{\sqrt{13}}\,j\)

\(\vec F \bullet \hat{v} = (0)\cdot \left(\frac{2}{\sqrt{13}} \right)+(-17)\cdot \left(\frac{3}{\sqrt{13}} \right)\)

\(\vec F \bullet \hat{v} = -\frac{51}{\sqrt{13}}\)

\(\vec F_{\parallel} = \left(-\frac{51}{\sqrt{13}} \right)\cdot \left(\frac{2}{\sqrt{13}}\,i+\frac{3}{\sqrt{13}}\,j \right)\)

\(\vec F_{\parallel} = -\frac{102}{13}\,i-\frac{153}{13}\,j\)

(b) Parallel and perpendicular components are orthogonal to each other and the perpendicular component can be found by using the following vectorial subtraction:

\(\vec F_{\perp} = \vec F - \vec F_{\parallel}\)

Given that \(\vec F = -17\,j\) and \(\vec F_{\parallel} = -\frac{102}{13}\,i-\frac{153}{13}\,j\), the component of \(\vec F\) perpendicular to \(\vec v\) is:

\(\vec F_{\perp} = -17\,j -\left(-\frac{102}{13}\,i-\frac{153}{13}\,j \right)\)

\(\vec F_{\perp} = \frac{102}{13}\,i + \left(\frac{153}{13}-17 \right)\,j\)

\(\vec F_{\perp} = \frac{102}{13}\,i -\frac{68}{13}\,j\)

(c) The work done by  \(\vec F\) through displacement \(\vec v\) is:

\(W = \vec F \bullet \vec v\)

\(W = (0)\cdot (2)+(-17)\cdot (3)\)

\(W = -51\)

Answer:

1. t = 5.89 s

2. h = 170 m

3. Vf = 57.8 m/s

Explanation:

1.

First, we analyze the horizontal motion of the golf ball. Assuming the air friction to be negligible, the horizontal motion will be uniform. So, e can use the following equation:

\(s = vt\)

where,

s = horizontal distance covered by the golf ball = 471 m

v = horizontal speed of golf ball = 80 m/s

t = time taken by the golf ball in air = ?

Therefore,

\(471\ m = (80\ m/s)t\\\\t = \frac{471\ m}{80\ m/s}\\\\\)

t = 5.89 s

2.

Now, we analyze the vertical motion. Using 2nd equation of motion:

\(h = v_{i}t + \frac{1}{2}gt^2\)

where,

h = height of cliff = ?

vi = vertical component of initial speed of ball = 0 m/s(ball was shot horizontally)

g = acceleration due to gravity = 9.81 m/s²

t = time of flight = 5.89 s

Therefore,

\(h = (0\ m/s)(5.89\ s) + \frac{1}{2}(9.81\ m/s^2)(5.89\ s)^2\)

h = 170 m

3.

Now, we can use 1st equation of motion:

\(v_{f} = v_{i} + gt\\v_{f} = 0 m/s + (9.81\ m/s^2)(5.89\ s)\\\)

Vf = 57.8 m/s

When ever there is a change in Velocity, there will be Acceleration. Let us now understand the concept of Acceleration with illustrative examples.

Let's suppose I have a car moving with a constant Velocity of 90 km along a straight line. It can be seen that the helicopter flying at roughly a speed of 20,000 km.

using the equation of motion formula;

S = ut + 1/2 + at²

Given,

S = 94 m

t = 5 sec

U = 0 initial velocity

S = ut + 1/2at²

94 = 0 + 1/2a 5²

a = (94 × 2)/ 25

The average acceleration of the motorcycle over the given distance is approximately 9.39 m/s².

To calculate the average acceleration of the motorcycle, we can use the formula:

Average acceleration = (final velocity - initial velocity) / time

First, let's convert the final velocity from km/h to m/s since the distance is given in meters. We know that 1 km/h is equal to 0.2778 m/s.

Converting the final velocity:

Final velocity = 78 km/h * 0.2778 m/s = 21.67 m/s

Since the motorcycle starts from rest (initial velocity is zero), the formula becomes:

Average acceleration = (21.67 m/s - 0 m/s) / time

To find the time taken to reach this velocity, we need to use the formula for average speed:

Average speed = total distance/time

Rearranging the formula:

time = total distance / average speed

Plugging in the values:

time = 50 m / 21.67 m/s ≈ 2.31 seconds

Now we can calculate the average acceleration:

Average acceleration = (21.67 m/s - 0 m/s) / 2.31 s ≈ 9.39 m/s²

Explanation:

To verify the hypothesis that the Earth has a liquid outer core and a solid inner core, we can use seismographs to study seismic waves that pass through the Earth's interior. The experiment can be set up as follows:

1. Select multiple seismograph stations around the globe to record seismic waves.

2. Choose a location for an earthquake to occur. The earthquake should be large enough to generate seismic waves that travel through the Earth's interior and be located far away from the selected seismograph stations.

3. Record the seismic waves generated by the earthquake at the various seismograph stations.

4. Analyze the seismic waves to determine how they interact with the Earth's interior. Specifically, we will study how the seismic waves pass through the Earth's outer and inner core.

5. Repeat the experiment using earthquakes of different magnitudes and at different locations, and record the resulting seismic waves.

Equipment needed for the experiment include seismographs, computers for data analysis, and earthquake monitoring systems. Seismographs can be installed in various locations around the globe to record the seismic waves generated by the earthquake. Data from these seismographs can be collected and analyzed using computer software to determine how the seismic waves interact with the Earth's interior.

Evidence that proves the outer core is liquid includes the observation of seismic waves that cannot travel through the liquid outer core, resulting in a shadow zone on the opposite side of the Earth from the earthquake. This shadow zone indicates that the seismic waves are refracted or absorbed by the liquid outer core. In contrast, evidence that proves the inner core is not liquid includes the observation of seismic waves that are reflected and refracted by the inner core boundary. This is due to the fact that the inner core is solid and has a different density and composition than the outer core.

To use repeatability to show whether the hypothesis is valid or not, we can repeat the experiment using earthquakes of different magnitudes and at different locations, and record the resulting seismic waves. If the results from multiple experiments are consistent with the hypothesis, then we can have greater confidence that the hypothesis is valid. If the results from multiple experiments are inconsistent, then we would need to investigate further to determine the cause of the inconsistency and revise the hypothesis accordingly.
