What is an eclipse?

When a planetary body passes in front of another planetary body and is visible from a third planetary body, an eclipse is created. Based on the relative positions of the sun, moon, and earth at the time of the eclipse, there are various types of eclipses in our solar system. For instance, a lunar eclipse occurs when the earth passes between the moon and the sun. The moon is pulled into the earth's shadow during a lunar eclipse, obstructing the sun's rays from reaching the moon. The sun, earth, and moon are also very tightly aligned during this time. Only with a full moon can there be a lunar eclipse.

For the solar eclipse to happen the light from the sun is obstructed by the moon observing from the earth.

Hence, Jake's experiment has a flaw stand facing the light bulb is the best statement that describes a method to correct the flaw in Jake's experiment. therefore the correct option is A.

6 . A transformer draws 24 W of power from a 220 V power line, stepping the voltage down to 7.5 V. What is the equivalent resistance of the input circuit?7.A circular loop of wire is in a spatially uniform magnetic field as shown. The magnetic field is directed into the screen and is perpendicular to the loop. What is the direction of the induced current in the loop, or is no current induced?

Answers

Answer:

6. 2017 Ω, about 2000 Ω.

7. no current is induced unless the field is changing

Explanation:

6. The relationship between power, voltage, and resistance is ...

P = V²/R

Rearranging gives

R = V²/P = (220 volt)²/(24 watts) ≈ 2016.667 Ω

The closest answer choice is 2000 Ω.

___

7.No current is induced in a stationary loop in a time-invariant magnetic field.

If something were changing, the direction of current induced would depend on whether the field is increasing or decreasing, and/or whether the loop is expanding or contracting.

Final answer:

The equivalent resistance of the input circuit is approximately 2028.33 ohms.

Explanation:

In this question, we are given the power input and the voltage input of a transformer, and we are asked to find the equivalent resistance of the input circuit. To find the equivalent resistance, we can use the formula:

Resistance = Voltage2 / Power

Using the given values of voltage (220 V) and power (24 W), we can substitute these values into the formula to find the equivalent resistance:

Resistance = (2202) / 24 = 2028.33 ohms

Therefore, the equivalent resistance of the input circuit is approximately 2028.33 ohms.

How many gallons are in a cubic gallon?

Answers

There's no such thing as a "cubic gallon". A 'gallon' is already a unit of volume,
only without the word 'cubic' in it.

If you like to play with different units of measure, here are a few conversions:

1 gallon = 231 cubic inches
1 cubic foot = 1,728 cubic inches = about 7.4805 gallons

1 cubic meter = 1,000 liters = 1 million cubic centimeters = about 264.17 gallons

When you run around a track at 5 km/h, your velocity is constant.

Answers

No it isn't. Speed and direction are both components of velocity.
When you run around the track at 5 km/hr, although your speed is
constant, your direction keeps changing, so your velocity does too.

Just after a motorcycle rides off the end of a ramp and launches into the air, its engine is turning counterclockwise at 8325 rev/min. The motorcycle rider forgets to throttle back, so the engine's angular speed increases to 12125 rev/min. As a result, the rest of the motorcycle (including the rider) begins to rotate clockwise about the engine at 4.2 rev/min. Calculate the ratio IE/IM of the moment of inertia of the engine to the moment of inertia of the rest of the motorcycle (and the rider). Ignore torques due to gravity and air resistance.

Answers

Answer:

$(Ie)/(lm) = 1.10*10^(-3)$

Explanation:

GIVEN DATA:

Engine operating speed nf = 8325 rev/min

engine angular speed ni= 12125 rev/min

motorcycle angular speed N_m= - 4.2 rev/min

ratio of moment of inertia of engine to motorcycle is given as

$(Ie)/(lm) = (-N)/((nf-ni))$

$(Ie)/(lm) = (-(-4.2))/((12125 - (8325)))$

$(Ie)/(lm) = 1.10*10^(-3)$

Answer: $1.105* 10^(-3)$

Explanation:

Given

Initial angular speed of engine( $\omega _E$ )=8325 rpm

Final angular speed of engine( $\omega _E_f$ )=12125 rpm

Initial angular speed of Motorcycle( $\omega _M$ )=0 rpm

Final angular speed of engine( $\omega _M_f$ )=4.2 rpm

as there is no external torque therefore angular momentum remains conserved

$I_E\omega _E+I_M\omega _M=I_E\omega _E_f+I_M\omega _M_f$

$I_E\omega _E+=I_E\omega _E_f+I_M\omega _M_f$

$I_E\left ( \omega _E-\omega _E_f\right )=I_M\omega _M_f$

$(I_E)/(I_M)=(\omega _M_f)/(\omega _E-\omega _E_f)$

$(I_E)/(I_M)=(-4.2)/(8325-12125)=0.0011052\approx 1.105* 10^(-3)$

How is sun related to nuclear, electromagnetic, and heat energy?

Answers

Answer;

The sun creates energy through nuclear fusion. Kinetic energy creates heat and light.

Explanation;

Solar energy from the sun is the primary source of energy on the surface of life that is important for sustaining life on earth.
Nuclear fusion occurring in the sun involves a nuclear reaction in which hydrogen nuclei fuse together to form helium nuclei and release energy.
Electromagnetic energy from the sun comes to Earth in the form of radiation. This energy travels through space at a speed equivalent to that of other electromagnetic radiations that is the speed of light.
The electromagnetic energy from nuclear fusion in the sun generates kinetic energy that in turn creates light and heat.

The nuclear energy is the source of energy production on the sun, then this travels to the Earth in the form of Electromagnetic radiation and as it heats up the other bodies in solar system, it gets converted into the heat energy.

Explanation:

The sun is considered to be the ultimate source of energy for the whole solar system. The energy produced in the sun reaches all the other planets in the solar system. The sunlight is a very big source of energy for the Earth also.

The energy produced on the sun is due to the nuclear reaction due to the immense pressure and temperature. This nuclear energy from the sun travels to the other bodies in the solar system by means of the electromagnetic radiations.

The electromagnetic radiations from the sun carry the heat energy to the bodies and as they reach the target, the target is heated up due to the conversion of the energy from the sun into the heat energy.

Thus, The nuclear energy is the source of energy production on the sun, then this travels to the Earth in the form of Electromagnetic radiation and as it heats up the other bodies in solar system, it gets converted into the heat energy.
