The correct answer is 10 years
Charge on one electron :
So, charge on ball having 97 electrons is equal to :
The main cause of weather is uneven heating of the earth's surface.
There are various factors that contribute to weather, however the main factor is the uneven heating of the earths surface. This creates temperature differences and can cause water to evaporate and condense. This, combined with earth's spin lead to large scale weather systems and wind currents. These in turn are influenced by land forms, bodies of water, and even vegetation.
Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
Distance = (speed) x (time)
Distance = (3 x 10⁸ meter/second) x (1 hour)
Distance = 3 x 10⁸ meter-hour per second
Distance = 3 x 10⁵ kilometer-hour per second
Hmmm. That answer is perfectly correct and totally useless. We have no idea how far one meter-hour per second is. It's a unit we never use. We'd better convert the answer to a unit of length that we use every day.
(3 x 10⁵ km-hour/sec) x (3,600 sec/hour) =
(3 x 10⁵ x 3,600) (km-hour-sec/hour-sec) =
1.08 x 10⁹ km
THAT's it ! A pulse of light in vacuum travels 1.08 billion km in one hour.
