1. Frequency:
The frequency of a light wave is given by:
where
is the speed of light
is the wavelength of the wave
In this problem, we have light with wavelength
Substituting into the equation, we find the frequency:
2. Period:
The period of a wave is equal to the reciprocal of the frequency:
The frequency of this light wave is (found in the previous exercise), so the period is:
Answer:0.0144 tesla
Explanation:
Magnetic field strength is the same as Magnetomotive force
B= I/2πr
B=magnetic field strength
I=current
r=radius=0.15/2=0.75m
Area=πr2= 1.77m2
torqueT= NIABsin theta
B= T/NIABsin theta
B=0.135/1 * 5.3 * 1.77 *sin90
B=0.0144 tesla
Answer:
The answer is C (The cost of the solar panels can be very high.)
<span>Water will diffuse down gradients of water potential, just as heat will flow down gradients of temperature and rocks will roll down gradients of gravitational potential</span>
Answer:
1. Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. We cover five states of matter on the site. Each of those states is sometimes called a phase. There are many other states of matter that exist in extreme environments.
2. hot buttered popcorn, burns my tongue, smells buttery, looks yellowish-white, tastes like butter, and sounds like popping corn.
3. The water is a liquid so it has the same shape had the pan.
4.Paper clips are attracted to magnets because iron has a magnectic force.
5. The first (or smallest measurement) you would see is the hash marking millimeters, which is written as "mm". 1mm equals the thickness of a dime. The unit of measure that is most often displayed on a metric ruler would be centimeters written "cm". 10mm equals 1cm and 2.5cm is about equal to 1 inch. Centimeters are displayed for viewing like inches are, marked on the ruler in increments of 1, 2, 3, 4... and so on. Usually to 30cm which is slightly less than 12 inches.
6. Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram.
