A flowerpot weighing 2 kilograms, what will be its speed at the end of 5 seconds?
Answers
That depends on what its speed was at the beginning of 5 seconds,
and on what exactly happened to it.
If it got pushed off of the window sill and fell to the ground below,
then the answer would depend on how high the window sill is.
If the flower pot kept falling for the whole 5 seconds, then its speed
would be 49 meters per second at the end of the 5 seconds. That's
because here on Earth, gravity increases the speed of falling things
by 9.8 meters per second for every second they fall.
Naturally, this answer is only true if the window sill is more than
122.5 meters above the ground ... about 402 feet, or 40 floors.
If it's lower than that, then the flower pot hits the ground in less
than 5 seconds, and its speed at the end of 5 seconds is zero.
By the way ...
-- It makes no difference how much the flower pot weighs.
All objects fall with the same acceleration, and hit the ground
at the same time.
-- 5 kilograms is a mass, not a weight.

Answer:
Quantity of charge = 80 Coulombs
Explanation:
Given the following data;
Current = 2 A
Time = 40 seconds
To find the amount of charge flowing through the light bulb;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge = current * time
Substituting into the formula, we have;
Quantity of charge = 2 * 40
Quantity of charge = 80 Coulombs

Most of the fusion occurs in the core.
In stars more massive than the sun, fusion continues through Deuterium, Carbon, and finally reaching iron/nickel.
Up to this point, the fusion reaction was endothermic, which means that the energy expended to produce the fusion reaction was exceeded by the energy produced in the reaction.
Fusion past iron is exothermic, and therefore the star will be able to survive by fusing elements heavier than iron.
After the core is almost entirely iron, the star is no longer in the Main Sequence.
So, fusion in stars more massive than the sun continue fusing until the core is almost entirely iron.

Answer:
final velocity will be
Explanation:
As we know that initial speed of the car will be
acceleration of the car is
time taken is
now we know that
You take your Initial Velocity and add to it all the gained velocity you get during this process (which is the Acceleration multiplied by the amount of Time you are accelerating for)
So we get (Final Velocity) = (Initial Velocity) + (Time)(Acceleration)
In your equations, thats (Final Velocity) = (10 meters/second) + (5 seconds)(2.1 meters/second/second)
Which is 10 + 10.2 = 20.2 meters/second
