When you rub a balloon against your hair or clothing, electrons that were previously on the hair/clothing will "jump" onto the balloon. Therefore, the balloon now has a negative charge accumulated on its surface.
When you bring that balloon near another balloon with a neutral charge, they will stick to each other, because the electrons on the surface will be attracted to the positive charges on the other. The positive charges that were previously randomly oriented now line up at the surface. However, after some time, the electrons move around back to their former random positions.
From my new perspective, the new intensity of the
light source has decreased by a factor of four.
Answer:
The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes.The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language.
Explanation:
The difference between the frequencies of the piano key and the tuning fork gives the frequency of the beats.
When the tuning fork is 405 Hz, and no beats are heard, then the piano key is also 405 Hz.
When the piano key is 405 Hz and the tuning fork is 402 Hz, then 405 - 402 = 3 beats are heard.
The piano key is 405 Hz.
Actually Welcome to the Concept of the Kinematics in real world.
So, as given here, we have to find the Mass of the bus from the given momentum, so we get as,
P = m * V
momentum = mass * velocity
here, P= 152625 kgm/s and v= 11.1 m/s
so substituting we get as,
m = 152625 ÷ 11.1 => 13,750 kg
hence,the mass of the bus is 13,750 kg.
