Answer:

20° slope

idek i just put it into a calculator

An inclined plane rises to a height of 2m over a distance of 6m. The angle of the slope is 20°.

A plane with or without friction is inclined at an angle to the horizontal direction or +x axis.

Given is the height of 2m over a distance of 6m.

Using the trigonometric relation, we get angle θ

tanθ = perpendicular / base

tanθ = 2/6

θ = tan⁻¹ (0.333)

θ =18.42°

Thus, the slope of the inclined plane is 18.42°.

Answer:

\(20.61\times 10^{5}Nm^{-2}\)

Explanation:

We are given that

h=20 cm=0.20m

1m=100 cm

Density of water=\(\rho=1.0\times 10^3 kg/m^3\)

We have to find the pressure experienced by driver at that depth.

Atmospheric pressure, P0=101 kPa

Pressure experience by driver

\(P=\rho hg+P_0\)

Where \(g=9.8\)

\(P=1.0\times 10^3\times 0.20\times 9.8+101\)

\(P=2061KPa\)

1 KPa=\(1000Nm^{-2}\)

The GPE of Mr. Butler and a box of Twinkies is 9016 J and KE of Mr. Butler and a box of Twinkies is 287.5 J

GPE = m g h

GPE = Gravitational potential energy

m = Mass

g = Acceleration due to gravity

h = Height

m = 115 kg

g = 9.8 m / s²

h = 8 m

GPE = 115 * 9.8 * 8

GPE = 9016 J

KE = 1 / 2 mv²

Answer:

7572 m/s

Explanation:

The force between two masses separated by a distance r is given as:

\(F=G\frac{m_1m_2}{r^2}\)

Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is \(6.674*10^-11 Nm^2/kg^2\)

The mass of the earth (\(m_1\)) is far greater than the mass of the sputnik (\(m_2\)). Therefore \(m_1m_2=m_1\). The mass of the sputnik is neglected, therefore:

\(F=G\frac{m_1}{r^2}=\frac{(6.674*10^{-11})(5.98*10^{24})}{(6.96*10^6)^2} = 8.2389N\)

But F is actually centripetal acceleration, a = v²/r

\(8.2389 = v^2 / 6.96*10^6\\v=7572m/s\)

Work done by the given force as the object moves from x = -1 m to x = +2 m is 21 J.

Force acting on an object moving along the x-axis Fx = (14x - 3.0x²) N

where x is in m.

Work done by force = ∫F dx, limits = -1 to 2

The given force Fx = (14x - 3.0x²) N

∴ Work done W = ∫F dx = ∫(14x - 3.0x²) dx, limits = -1 to 2= [7x² - x³] from x = -1 to 2= [7(2)² - (2)³] - [7(-1)² - (-1)³]= [7(4) - 8] - [7 - (-1)]= 28 - 7= 21 J

The electrical power generated by a residential solar panel array with a surface area of 457ft² is 6580.8 watts.

The commercial solar panel generates about 0.10 W/in². To find the electrical power generated by a residential solar panel with a surface area (S) of 457 ft²  we need to convert the unit from ft² to in², as follows:

\( S = 457 ft^{2}*\frac{144 in^{2}}{1 ft^{2}} = 65808 in^{2} \)

Then, the electrical power generated is:

\( P = \frac{0.10 W}{in^{2}}*65808 in^{2} = 6580.8 W \)

Astronomers are able to explore layers of Sun below the photosphere through various observational techniques, instruments that enable the study of different wavelength of light and other particles emitted by Sun.

One such technique is helioseismology, which involves studying the vibrations or oscillations of the Sun's surface. By analyzing the patterns and frequencies of these oscillations, scientists can infer information about the internal structure and properties of the Sun's layers, including the convection zone and the radiative zone.

Additionally, observations made using X-ray, ultraviolet, and gamma-ray telescopes provide insights into the Sun's outer layers and the processes occurring within them. These higher-energy wavelengths can penetrate the Sun's lower atmospheric layers, allowing astronomers to study phenomena such as solar flares, coronal loops, and prominences.

Furthermore, neutrino detectors located deep underground are used to capture neutrinos emitted by nuclear reactions in the Sun's core. By detecting and analyzing these neutrinos, scientists can indirectly study the properties and conditions of the solar interior.

By combining data from these various observational techniques, astronomers are able to explore and understand the layers of the Sun below the photosphere and gain valuable insights into the dynamics and behavior of our nearest star.

The cost of energy consumption to operate the heater for 15 days is $2.25

Voltage (V) = 200 V

Current (I) = 25 A

Power (P) = VI = 200 * 25 = 5,000 W

Now, the calculation of the energy consumption for 15 days in KW/h

We will convert W to kW,

1000 W = 1kW

Therefore,

5,000 W = 5000 W × 1 KW / 1000 W = 5kW

The daily energy consumption will be calculated. This is attainable as follows,

P = 5kW

Time(t) = 10 h

Energy (E) = P/t = 5/10 = 0.5 kW/h per day.

Finally, we will calculate the energy usage for the next 30 days. This is attainable as follows:

1 day = 0.5 kW

Cost of one day = 0.5 * 0.30 = $ 0.15

Now, the cost to operate the heater for 15 days = $ 15 * 0.15 = $2.25

To calculate the magnitude of the force exerted on the wire by the Earth's magnetic field, we can use the formula:

F = I * L * B * sin(θ)

Where:

F is the force,

I is the current in the wire (1.5 A),

L is the length of the wire (2.1 m),

B is the magnetic field strength (0.55 gauss = 0.055 T),

θ is the angle between the direction of the current and the magnetic field.

Since the current is running from north to south and the magnetic field is from south to north, the angle between them is 180 degrees (or π radians). The sine of 180 degrees is 0, so the force becomes:

F = I * L * B * sin(180°)

 = I * L * B * 0

 = 0

Therefore, the magnitude of the force exerted by the Earth's magnetic field on the wire is zero.

Examples of amorphous solids include Metals. Hence, the correct option is (A).

Amorphous solids are materials that lack long-range order in their atomic or molecular structure, and therefore have properties that are different from those of crystalline solids. Examples of amorphous solids include glass, plastics, gels, and some ceramics. Thermal energy is not an example of an amorphous solid, as it is a form of energy rather than a material. Nitrogen, on the other hand, can exist in both amorphous and crystalline forms, depending on the conditions of formation.

The wire has a resistance of 635 ohm.

Describe resistance.

A force that opposes the flow of current is known as electrical resistance, also known as resistance to electricity. It serves as a barometer for how challenging current flow is in this way. Resistance values are expressed in ohms ().

When there is an electron difference between two terminals, electricity will flow from high to low. In opposition to that flow is resistance. As resistance rises, the current declines. The current rises as the resistance falls, which is also true.

1. V = 2 V, I = 3.2 * 10-3 A, and area = 2.5 mm2 are all possible differences.

Resistance is calculated by dividing the potential difference across the wire by the current flowing through it, which results in a value of 2/(3.2*10-3) = 625 ohm.

2. Two resistors R linked in parallel have an equivalent value of R2/2R, or R.

The net equivalent resistance is equal to 2R + R/2 = 5R/2 when this is connected in series with a resistor of resistance 2R.
