Answer:
They fold to create ridges and valleys perpendicular to the direction to which pressure is applied.
<span>We need to calculate the number of seconds in one year.
time = (365 days) (24 hours/day) (3600 seconds/hour)
time = 31536000 seconds
We can calculate the distance that light travels in this many seconds.
distance = speed x time
distance = (3.00 x 10^8 m/s) (31536000 seconds)
distance = 9.46 x 10^{15} meters
A light year is 9.46 x 10^{15} meters</span>
Answer:
Show attached picture
Explanation:
Let's call V the voltage provided by the battery in the circuit. M is the multimeter (let's call 
its internal resistance) and R indicates the resistance of the light bulb.
We know that the meter's internal resistance is 1000 times higher than the bulb's resistance:
(1)
Both the meter and the bulb are connected in parallel to the battery, so they both have same potential difference at their terminals:
Using Ohm's law, 
, we can rewrite the previous equation as:
where
is the current in the meter
is the current in the bulb
Using (1), this equation becomes
so, the current in the meter is 1000 times less than through the bulb.
Answer:
Explanation:
Steam spins turbine blades, turning a generator shaft to create electricity.
Heat energy is converted to mechanical energy and then electricity.
A rubbber band becomes warm when stretched repeatedly because it stores its energy as thermal energy. When you stretch the rubber band again and again, this gives the rubber more thermal energy, causing it to heat up.
