It'll speed up in the direction it's being pushed unbalanced. Or, it could slow down if applied the right amount of unbalanced power. And finally if the unbalanced push is pushed it could change the direction of it's current motion it was traveling.<span>

Electric power is given by:
Power = voltage x current
10000 = 15.8V
V = 633 Volts
Answer:
a) t = 0.75 s, b) t = 2.25 s
Explanation:
The speed of sound is constant in a material medium
v = 340 m / s
we can use the relations of uniform motion to find the time
v = x / t
t = x / v
In the exercise, the observer's distance to the wall is indicated d = 510 m, it also indicates that the shot is fired at the midpoint
x = d / 2
a) direct sound the distance from the observer to the screen is
x = 510/2 = 255 m
t = 255/340
t = 0.75 s
b) echo sound.
In this case the sound reaches the wall bounces, the distance is
x = d / 2 + d
x = 3/2 d
x = 3/2 510
x = 765 m
the time is
t = x / v
t = 765/340
t = 2.25 s
Answer:
Yes, the frequency of light emitted is a property of the difference between the levels of energy of its electrons.
Explanation:
Neon atom is a noble gas which glows when its electrons de-excites after absorbing energy.
Niels Bohr postulated that the energy level in all atoms are quantized, thus electrons do not exist in-between two levels. When electrons in the Neon atom are excited, this increase in energy causes them to jump to a higher energy levels. On de-excitation, the electrons drops to their initial level releasing the absorbed energy in the form of a photon.
The photon emitted has a frequency that is directly proportional to the energy change in the electron.
I do not know
hi I thinks the answer is Tralse
