Answer:
a) 980 N
b) 100 kg
c) 163.33 N
Explanation:
a)
The weight of the object on Earth is the product of its mass times the acceleration due to gravity, that is:
b)
The mass of the object on the moon, is exactly the same (100 kg) since mass is an inherited value of the object.
c)
Considering that the acceleration of gravity on the Moon is about 1/6 that we have on earth (g), then the weight of the object on the Moon becomes:
Answer:Increase by a factor of 25
Explanation:
We know that magnetic force is proportional to
where r is the distance between them
Thus
Where =magnetic field
If distance is reduced by a factor of then force must increase by a factor of
because
so
Answer:
Frequency
Explanation:
Photons are the packet of energy. They are massless and chargeless particles. They travel in the vacuum with the speed of light. The energy of photon is given by :
Where
h = Planck's constant
= frequency of photon
Or
c = speed of light
= wavelength of photon
From the above equation, it is clear that the energy of photon is directly proportional to its frequency.
Answer:
The consecutive charge configuration has a more intense field than alternating
Explanation:
In each corner we place a different account there are only two different settings, see attached.
In the case of alternating charging (+ - + -) see diagram 1, the electric field in the center is canceled in pairs, resulting in a zero field
In the case of consecutive loads (+ + - -) in this case we have a result between the two charges, therefore the total field is
E = 2 k q / ra2 a cos 45
The consecutive charge configuration has a more intense field than alternating
