Answer:
Energy density will be 14.73
Explanation:
We have given capacitance
Potential difference between the plates = 365 V
Plate separation d = 0.200 mm
We know that there is relation between electric field and potential
, here E is electric field, V is potential and d is separation between the plates
So
Energy density is given by
1) Forces acting on your body: force of gravity and normal reaction
2) Due to Newton's second law, N = mg
Explanation:
1)
When you sit on the computer, there are only two forces acting on you:
- The force of gravity, acting downward, of magnitude , where m is your mass and is the acceleration due to gravity, downward
- The normal reaction exerted by the chair on you, , acting upward
Your body is in equilibrium (it doesn't move), this means that the two forces balance each other, therefore:
2)
We can now apply Newton's second law of motion to this situation; this law states that the net force acting on a body is equal to the product between its mass and its acceleration. Mathematically,
where
is the net force
m is the mass
a is the acceleration
In this situation, the net force is
So the equation becomes
However, we observe that your body is at rest; therefore, the acceleration is zero:
a = 0
And therefore,

Answer:
Chemical energy to Electrical energy to Light energy
Explanation:
- Chemical energy; This is the energy stored in the battery.
- Electrical energy; This is the energy transformed by the battery and sent through the connecting wires to the lightbulb
- Light energy; When the electrical energy gets to the light bulb ,the light bulb converts it to light energy. Which is seen when the light bulb is turned on.
Here is the answer. The microscope parts that should routinely be adjusted to control the light source and provide optimal illumination of the specimen are the following: <span>light source; condenser; specimen; objective lens; ocular lens. Hope this answers your question.</span>
Answer:
High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms), ice storms, and duststorms.
Explanation:High winds- wind speeds as low as 23 knots (43 km/h) may lead to power outages when tree branches fall and disrupt power lines. Once wind exceed 135 knots (250 km/h) within strong tropical cyclones and tornadoes, homes completely collapse, and significant damage is done to larger buildings. Total disruption occurs once wind exceeds 175 knots (324 km/h)
Tornado- Typically look like a narrow funnel reaching from the clouds to the ground. Their wind speed goes from 65 to 250 miles per hour.
"An extreme weather condition in which we face the high speed wind in combination with heavy snow."
As for any blizzard has the normal wind speed of about 40 mph, and the visibility range reduces to less then 500 ft.
