Average amount of time wind machines operate
Answers
The wind machine on an average operates for a time of about .
Explanation:
The wind energy is the method of using the energy carried by the wind to generate the power. The wind energy is the considered as the conventional and clean source of energy.
The wind machines require the high power winds to rotate the blades of the windmill and produce power using the energy of the moving wind.
The winds blow at such high speed for a very small time during the day, the wind machine cannot be expected to work for a longer time during the whole day.
The wind energy can be obtained form a wind mill for a limited time unlike the other form of energy like thermal energy or even the solar energy. The thermal energy can be obtained at anytime due to burning of fuel whereas the solar energy can at least be obtained during the whole day time.
Thus, the wind machine on an average operates for a time of about .

We have no information describing the direction in which
the object is moving, so we're in no position to discuss its
velocity. ==> We have only speed to work with.
Kinetic energy = (1/2) (mass) (speed²)
(350 J) = (1/2) (6 kg) (speed²)
Divide each side by 3 kg : (350J / 3 kg) = (speed²)
Take the square root of each side: Speed = 10.8 m/s (rounded)
Units (for the curious/inquisitive):
[Energy] = [work] = [force] x [distance]
= [mass-distance/time²] x [distance]
= [ kg-meter / sec² ] x [ meter ]
= [ kg-meter² / sec² ] = Joule
Energy / mass = Joule/kg = [ meter² / sec² ] = (speed²)

An electromagnetic am band radio wave could have a wavelength of 500m, i.e., 500 meters(Option 3).
What is wavelength?
A wavelength is a disturbance that travels into space with a given frequency and amplitude.
- Electromagnetic wavelengths can be classified depending on their type of frequency.
In conclusion, an electromagnetic am band radio wave could have a wavelength of 500m (Option 3).

Answer: The correct statement is the positive charge in an atom must be located in a dense central mass.
Explanation:
Rutherford gave an experiment called as gold foil experiment.
In his experiment, he took a gold foil and bombarded it with alpha particles which carry positive charge of +2 units. He at first thought that the particles will pass straight through the foil, but to his surprise, many of them passed through, some of them deflected their path and a few of them bounced back straight from their path.
From this observations, he concluded that in an atom, there exist a small positive charge that is present at the center. Because of this positive charge, the alpha particles deflected their path and some of them bounced straight back their path.
Thus, the correct statement is the positive charge in an atom must be located in a dense central mass.

To calculate the total distance traveled, we need to consider the distances traveled in each direction. Let's break it down step by step:
1. Walking 6 blocks east: When you walk 6 blocks east, you cover a distance of 6 blocks.
2. Walking 2 blocks north: After walking east, you then walk 2 blocks north. This adds an additional distance of 2 blocks.
3. Walking 3 blocks west: Next, you turn and walk 3 blocks west. This cancels out part of the distance you covered while walking east. So, you subtract 3 blocks from the total distance.
4. Walking 4 blocks south: Finally, you walk 4 blocks south. This cancels out part of the distance you covered while walking north. So, you subtract 4 blocks from the total distance.
To calculate the total distance traveled, we can add up the distances traveled in each direction:
Distance traveled east: 6 blocks
Distance traveled north: 2 blocks
Distance traveled west: -3 blocks (subtracting 3 blocks cancels out part of the distance traveled east)
Distance traveled south: -4 blocks (subtracting 4 blocks cancels out part of the distance traveled north)
Now, we can add these distances together:
6 blocks + 2 blocks + (-3 blocks) + (-4 blocks) = 1 block
Therefore, the total distance you travel is 1 block.
