Answer:
It would take approximately 31.2×10^6 years
Explanation:
Average speed = distance/time
Time = distance/average speed
distance = 8.1 light-years = 8.1×9.461×10^12km = 7.66341×10^13km
average speed = 280km/hr = 280km/hr × 8766hrs/year = 2454480km/year
Time = (7.66341×10^13km)/(2454480km/year) = 31.2×10^6 years
Answer:
Explanation:
As we know that backpack is kicked on the rough floor with speed "v"
So here as per force equation in vertical direction we know that
so normal force on the block is given as
now the magnitude of kinetic friction on the block is given as
now when bag is sliding on the floor then net deceleration of the block due to friction is given as
now we know that bag hits the opposite wall at L distance away in time t
so we have
Once a hypothesis is tested and confirmed, and then tested again and confirmed again many many others, it may provide the basis for or become a part of, a
Scientific theory.

Answer:
In metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
Explanation:
Here we asked to divide 1 meter in to 100 equal parts.
Let us find out what is the length of piece when 1 m is divided in to 100 equal parts.
Length
That is length of 1 m divided into 100 equal parts is 0.01m.
We know that 0.01 m is 1 centimeter.
So, in metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
Potential energy is the energy by virtue of object's height & kinetic energy by virtue of it's motion!
