Answer:
The maximum electric field
Explanation:
From the question we are told that
The diameter is
The magnetic field of the cylinder is
The frequency is
The radial distance is
This magnetic field can be represented mathematically as
The initial magnetic field is the average between the variation of the magnetic field which is represented as
Then is the amplitude of the resultant field is mathematically evaluated as
The electric field induced can be represented mathematically as
At maximum electric field
OK.
You're sitting in a soft comfy chair, reading a book in your lap.
The book stays put, and you eventually start to get sleepy, because
there's almost no acceleration happening.
The chair you're sitting in is seat #27B in a huge jet taking you to visit
your grandparents who live a thousand miles away.
The airplane is maybe 7 miles up, passing over the ground at nearly
500 miles per hour, flying straight, level, and fast !
Answer:
51.28 grams of fat will gain
Explanation:
Correction: 10,000 kj about 2500 cal not 2500 kcal.
Asumption: basal metabolic rate will depend of weight, lenght, age and gender but its estipulated a 2000 cal basal metabolic rate as a standar for the calculation for nutritional value of food.
eating a 2500 cal in one day will left
Consuming about 2,500 calories in a day where you only sit relaxed for 16 hours and the rest of the time was used to sleep will mean a basal metabolism of 2000 cal, so 500 calories were left unused, taking into account that 1 calorie is about 4 kj we have to
500 cal * 4kj / cal = 2000 kj
The amount of energy stored as fat will be given by the following equation:
Unused energy / energy contained in one gram of fat = 2000 kj / (39 kj / g) = 51.28 grams of fat gain
That's the <em><u>speed</u></em> of the wave.
("Velocity" is not a good way to say it, because 'velocity' always needs a direction,
and neither frequency nor wavelength tells anything about direction.)
Answer:
Explanation:
We can solve the problem by using Kepler's third law, which states that the ratio between the cube of the orbital radius and the square of the orbital period is constant for every object orbiting the Sun. So we can write
where
is the distance of the new object from the sun (orbital radius)
is the orbital period of the object
is the orbital radius of the Earth
is the orbital period the Earth
Solving the equation for , we find
