Answer:
angular momentum, 
Explanation:
Given that,
Mass of the woman, m = 50 kg
Angular velocity of the disk, 
Mass of the disk, m' = 2670 kg
Radius of the disk, R = 4 m
We need to find the magnitude of the total angular momentum of the woman–disk system. The moment of inertia of the system is equal to the sum of moment of inertia of women and the moment off inertia of the disk.

The angular momentum is given by :

or

So, the magnitude of the total angular momentum of the woman–disk system is
. Hence, this is the required solution.
Answer:
124.52 mL
Explanation:
from Boyle's Law,
PV = P'V' ................... Equation 1
Where P = Initial pressure of the gas, V = Initial volume of the gas, P' = Final pressure of the gas, V' = Final volume of the gas.
make V' the subject of the equation.
V' = PV/P'............. Equation 2
Given: P = 267 torr = (267×0.00131) = 0.34977 atm, V = 356 mL, P' = 1 atm
Substitute into equation 2
V' = (0.34977×356)/1
V' = 124.52 mL.
Hence the new volume of the balloon = 124.52 mL
Answer:
so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
Explanation:
As we know that the air friction or resistance due to air is neglected then we can use the equation of kinematics here

since we released it from rest so we have

so here we have

now if the distance is double then we have

now from above two equations we can say that

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
1. I think it's the trails left by an electron as it moves around the nucleus.
2. The atomic number is the number of protons so it is 8.
3. It's mass is lowered but it is still the same element.
Answer:
V4=9.197v
Explanation:
Given:
V1= 18v ,V2= 12v ,r1=r5=58ohms ,r2=r6=124ohms , r3=47ohms ,r4= 125ohms
V4= I4R4 = V2/(R4 + R5)×R4
V4= 12×125 /(125 + 58)
V4=1500/183 =9.197v
