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.
Answer:
the expression is ΔT = v²/(4*c)
Explanation:
the kinetic energy K of the bullet is given by
K=1/2*m*v²
where m= mass , v= velocity
the heat Q absorbed by the bullet is given by
Q = m * c * ( T final - T initial ) , where c= specific heat of lead, T initial = initial temperature, T final = final temperature
then
thermal energy = kinetic energy converted into thermal energy
Q = K - 1/2* K = 1/2*K
replacing values
m * c * ( T final - T initial ) = 1/2* 1/2*m*v² = 1/4*m*v²
the increase in temperature ΔT = ( T final - T initial ) , then
ΔT = ( T final - T initial ) = 1/4*m*v² /(m * c ) = v²/(4*c)
ΔT = v²/(4*c)
Answer:
Distance of Alpha century in miles
Distance of Alpha century in Astronomical unit
Explanation:
Given
Distance of Alpha Centauri from the Solar System light year
Light year is the distance traveled by light in one year. Its a unit of measurement for distant celestial objects
One light year miles
Total number of miles in light years is equal to
Distance of Alpha century in miles
Number of astronomical units in one light year
Total number of astronomical units in light years is equal to
Distance of Alpha century in Astronomical unit
Explanation:
The text reads;
"The two flat mirrors X and Y face each other and form a 60-degree angle. One light goes to X with the angle coming 60 degrees until it is reflected Y. Calculate the angle of reflection of the light leaving Y".
