Answer
given,
Electric field,E = 490 N/C
time, t = 54 ns
for electron
Mass of electron me = 9.1 x 10⁻³¹ kg
Charge of electron e = -1.6 x 10⁻¹⁹ C
electrostatic force
F = E q
F = 490 x 1.6 x 10⁻¹⁹
F = 784 x 10⁻¹⁹ N
now, using newton second law
a = 8.62 x 10¹² m/s²
using equation of motion
v = u + a t
v = 0 + 8.62 x 10¹² x 54 x 10⁻⁹
v = 4.65 x 10⁵ m/s
velocity of electron is equal to v = 4.65 x 10⁵ m/s
For Proton
Mass mp = 1.67 x 10⁻²⁷ kg
Charge p = 1.6 x 10⁻¹⁹ C
Electric field E = 490 V/C
from above solution
F = 784 x 10⁻¹⁹ N
now, acceleration
a = 4.69 x 10¹⁰ m/s²
using equation of motion
v = u + a t
v = 0 + 4.69 x 10¹⁰ x 54 x 10⁻⁹
v = 4.65 x 10³ m/s
velocity of electron is equal to v = 4.65 x 10³ m/s
Derek's experiment best demonstrates the effects of gravity, that force made the water go down and hit the ground, the effect of that was a depression.
The definition of Hydrosphere is all the water of earth surface, so the water represents Hydrosphere.
The definition of Geosphere is the surface of Earth, when the water fell down and touched the ground it caused an interaction between Hydrosphere and Geosphere.
We have to convert Gm/s to m/s.
As 
Therefore the speed of light in vacuum,
Thus, the speed of light in m/s is 
Answer:
Yellow, green, polka dot and white jerseys
Explanation:
Tour de France is the biggest bicycle race in the world held at France over a period of 23 days. At the end of each day of racing they give to the certain riders FOUR different colored jerseys:
- The yellow jersey is given to the overall winner at each stage, this shows the rider who was the best in the previous stage.
- The green jersey is given to the best sprinter of each stage,
- The polka dot jersey is given to the rider who first reach the crest of designated hills and mountains at each stage.
- The white jersey is given to the fastest rider at each stage under 25 years at the beginning of the racing year.
At the end of the competition, the total points are counted and the different jerseys are given to the overall winners.
