Answer:
Explanation:
Given that,
The mass of a golf ball, m = 40 g = 0.04 kg
Its angular velocity, 
The radius of the sphere is 2.5 cm or 0.025 m
We need to find the magnitude of the angular momentum of the ball. It is given by the formula as follows:
Where I is moment of inertia
For sphere, 
So, the magnitude of the angular momentum of the sphere is 
.
I think the correct answer would be old and metal poor stars are found in the galactic nucleus. This nucleus us a region in the center of a galaxy which contains a higher luminosity than other parts. It produces very high amounts of energy. Hope this helps.
Answer;
=84 kwh
Explanation;
Electrical energy = 1000 watts
1000 watt = 1 kilo watt
1 week = 7 days
Number of hours = 7 × 12× = 84 hours
Consumption
= 1 kw × 84 hours
= 84 kwh
Current can vary in different branches of a circuit
Answer: 0.00000938422m^3
Explanation:
dV=Vø*β*(t1-tø)
The parameters are
dV is the change in volume after temperature increase
Vø =0.607 *10^-3m3 is the initial vokume of coffe at 16.2^0 C
β= coefficient of volume expansion of water at 16.2^0 C is 0.0002/0C
t1= 93.5^0C final temperature
tø=16.2^0 C
Therefore
dV=0.607 *10^-3 *0.0002*(93.5-16.2)
dV= 0.00000938422m^3
This is the volume of coffee that will spill over the container
