Question: The least common shape for a galaxy _____.
Answer: <u>Cluster</u>
True
The rate at which work is done is referred to as power. A task done quite quickly is described as having a relatively large power. The same task that is done more slowly is described as being of less power. Both tasks require he same amount of work but they have a different power.
Answer:
Explanation:
Consider that F (any function) <0 .
u(x,y) is a coontinuous function in the closed interval or region R.
Let us consider a point (p,q) that is inside the region and it is a maximum point.
Then it should be must
uxx (p,q) <0 where uxx means double differentiation
and uy(p,q) >0
Since ux(p,q) = 0 = uy(p,q) where ux and uy means single differentiation with respect to x and y respectively.
Say, Maximum limits of the region is T
therefore q<T
then uy (p,q) = 0 if q<T
if q = T then
point (p,q) = (p,T) will be on the boundary of R then we claim that
uy(p,q) >0
Similarly for the minimum also it will work
Answer: The answer is A) 49 N(Newtons).
Answer:
P = 1401.4 x 10⁶ W
Explanation:
Given that
Water flow rate m = 2.2 x 10⁶ kg/s
Height ,h= 65 m
Acceleration due to gravity ,g= 9.8 m/s²
The power P is given as
P= m g h
P=Power
m=Water flow rate
h=height
Now by putting the values in the above equation
P = 2.2 x 10⁶ x 9.8 x 65 W
P = 1401.4 x 10⁶ W
Therefore the power wasted will be 1401.4 x 10⁶ W.
