Answer:
K1/K2=4
Step-by-step explanation:
The kinetic energy of a rotating sphere is given by:
The moment of inertia of a solid sphere is given by
The initial kinetic energy is therefore
The final kinetic energy is given by
Therefore the relation K1/K2 if R2 = 0.5R1
The text says nothing about the final angular velocity just the collapse of the collapse of the radius
Answer: the answer should be 875 cubic feet
Step-by-step explanation:
The why is because we have to divide each rectangular prism into different pieces to use the volume formula. Doing this gives us 5*15*5 for the first part, the second part will be 20*5*5, the third square is 5*5*5.
Answer:
HCF=3
Step-by-step explanation:
Factors of 15t= 3*5*t
Factors of 6s= 2*3*s
HCF= Common factors
common factor = 3
HCF=3
Answer:
first thing to do is get up from your sit and go cry because that question is to hard
Answer:
Up
Step-by-step explanation:
Y= 1x^2 + 3x + 9
Y= Ax^2 + Bx + C
To determine which way a parabola opens just look at the coefficient (the number) of the x^2 - Always use the coefficient that is beside the x^2
So, if the coefficient A is positive the parabola is opening upward
if the coefficient A is negative the parabola is opening downward
