Answer:
T = 0.607 seconds
Explanation:
Given:
Mass, M = 1.50 × 10⁻² kg
Radius, R = 5.50 × 10⁻² m
Now,
the time period in terms of moment of inertia is given as:
.....................1
where, T is the time period
g is the acceleration due to gravity
I is the moment of inertia
Now,
Moment of inertia, I is given as:
on substituting the moment of inertia in the equation 1, we get
or
on substituting the valeus, we get
or
T = 0.607 seconds
Hence, the time period is 0.607 seconds
Answer: 44.57°C
Explanation:
The following can be deduced from the question:
Specific heat of water = 4.186 J/kg
From the question, we can infer that 625 × 4.186 joules of heat will be lost when there's a 1°C drop of water.
We then calculate the amount if degrees that it'll take to cool for 7.96 x 10⁴J. This will be:
= 7.96 × 10⁴ /(625 × 4.186)
= 79600/(625 x 4.186)
= 79600/2616.25
= 30.43°C
The final temperature will then be:
= 75.0°C - 30.43°C
= 44.57°C
<span>Voltage overcomes the resistance of the electromagnet winding to force a current through that resistance. The field strength is proportional to the coil current. More voltage pushes more current. More voltage builds up the current faster, as well as forcing it to a higher final value. </span>
-- Light travels straight, not around in a circle. But if it did, it would cover
a distance equal to the length of the equator in about <em>0.13 second</em>.
-- At the speed of sound (in air at standard temperature and pressure),
it would take about <em>32.6 hours </em>to cover the same distance.
Answer:
They interact in a lot of ways, prey, predator, etc.
