Answer:
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
-- Free neutrons collide with Uranium nuclei.
If one is absorbed, then
-- the Uranium nucleus falls apart,
producing
-- smaller nuclei,
-- energy,
and
-- more free neutrons.
Answer: 1479watts
Explanation:
Power is defined as the energy expended or work done in a specific time.
Mathematically,
Power = Workdone/time taken
Since work done is force × distance
Power = force × distance/time
Force = Mary's weight = 87N
Distance = height of the flight = 102meters
Time = 6.0seconds
Substituting in the formula we have;
Power = 87 × 102/6
Power = 1,479watts
Note that the time must be in seconds before usage. If its given in minutes, you will have to convert to seconds
You use the equation kinetic energy = 1/2 mass X velocity^2 so your answer is 25000J.
Answer:
The corresponding dimensions will be "x = 300 & y = 60".
Explanation:
Available fencing = 600 ft
Fencing,
⇒ 
⇒ 
As we know,
⇒ 
On substituting the given values, we get
...(equation 1)
On differentiating with respect to y, we get
⇒ 
On putting the values of y in equation 1, we get
⇒ 
⇒ 
⇒ 
⇒ 
Dimensions of the rectangular area:
x = 300
y = 60
