The Answer:
The diameter will be reduced or shorten to prevent the induced current in the metal loop
explanation:
Magnetic flux is given as
Φ = BA•Cosθ
Since the angle is kept constant.
So to have same magnetic flux with larger magnetic field required only the diameter to changed
From the equation above,
Φ = BA•Cosθ
B= Φ / A•Cosθ
Since both Flux and the angle is constant
Then, The magnetic field is inversely proportional to the Area
And the areas is a function of diameter, Area = πd²/4
So to have a larger magnetic field, we need to reduce or shorten the diameter.
As d reduces, B increases.
a).
-- There were 10.00 mL of water in the graduated cylinder originally.
-- After the marble was added to the cylinder and sank, the total volume
of water and marble in the cylinder was 11.20 mL.
-- The extra 1.20 mL that suddenly showed up was the volume of the marble.
-- We can use 1 mL = 1 cm³ .
-- The volume of the marble was <em>1.20 cm³ </em>.
b).
Density = (mass) / (volume)
For the marble . . .
Density = (3.05 g) / (1.20 cm³) = <em>2.54 gm/cm³</em> (rounded)
Answer:
(a) I=0.01 kg.m²
(b) I=0.03 kg.m²
Explanation:
Given data
Mass of disk M=2.0 kg
Diameter of disk d=20 cm=0.20 m
To Find
(a) Moment of inertia through the center of disk
(b) Moment of inertia through the edge of disk
Solution
For (a) Moment of inertia through the center of disk
Using the equation of moment of Inertia
For (b) Moment of inertia through the edge of disk
We can apply parallel axis theorem for calculating moment of inertia
<span>Poet Kuangchi Chang did not remain in China long enough to be "re-educated." Following the Communist takeover he fled to the United States. His poem "Garden of My Childhood" describes China before the revolution as a peaceful, idyllic garden with a violent horde rapidly approaching. A vine, the wind, and the sea are each personified, and each beckons for him to run. It is not until "eons later," when he is "worlds away," that his "running is all done," and he finds himself at his destination: another garden, just like the one he had left behind.</span>
Answer:
Glucose
Explanation:
During exercise, muscles need more energy. They get this energy by aerobic respiration, which uses oxygen and glucose to release energy.
Note: If the body fails to supply oxygen to the muscles fast enough, the muscles will produce energy by anaerobic respiration, which is not as effective as aerobic respiration in addition to producing lactic acid.
