Time dilation is the slowing of the passage of time at high speeds. The faster the object moves, the greater the amount of time dilation. Time dilation, in part, accounts for the constant speed of light, regardless of the light's source and regardless of the observer's perspective.

Answer: Ionization
</h2>
The inner atmosphere of a <u>cloud chamber</u> is composed of an easily ionizable gas, this means that little energy is required to extract an electron from an atom. <u>This gas is maintained in the supercooling state, so that a minimum disturbance is enough to condense it</u> in the same way as the water is frozen.
<h2>Then, when a charged particle with enough energy interacts with this gas, it <u>ionizes</u> it.
</h2>
This is how alpha particles are able to ionize some atoms of the gas contained inside the chamber when they cross the cloud chamber.
These ionized atoms increase the surface tension of the gas around it allowing it to immediately congregate and condense, making it easily distinguishable inside the chamber like a <u>small cloud</u>. In this way, it is perfectly observable the path the individual particles have traveled, simply by observing the cloud traces left in the condensed gas.
Answer:
2.08 x 10⁻⁶ T
Explanation:
= velocity of electron = 5.0 x 10⁷ m/s
q = charge on electron
B = magnetic field = ?
E = electric field = 104 V/m
Magnetic force on the electron is given as
Electric force on the electron is given as
For the electron to pass without being deflected, we must have
(5.0 x 10⁷) B = 104
B = 2.08 x 10⁻⁶ T
Answer:
1.5 × 10^11 meters
Explanation:
the distance of the Earth to the Sun is 1.5 × 10^11meters
Answer: 18.81m/s^2
Explanation:
Given the following :
Height of building = 0. 1 km = 100m
Horizontal distance = 85m
Using the equation :
S = 1/2gt^2
And S = 100, g = 9.8m/s^2
100 = 0.5(9.8)(t^2)
100 = 4.9(t^2)
t^2 = (100 / 4.9)
t^2 = 20.408
t = 4.5175214
t = 4.52s
Therefore, initial velocity of ball in horizontal direction;
Using the equation:
S = ut + 0.5at^2
a in horizontal direction = 0
Therefore,
S = ut
85 = u × 4.52
u = (85 / 4.52)
u = 18.805
u = 18.81m/s
