Answer:
Lightning strikes the empire state building at an average of about 23 times a year.
Explanation:
The Empire State Building is one of the tallest buildings in New York. Because of how high it stretches up into the sky, lightning strikes are quite common to it. This is because part of the building touches the clouds which are usually charged during thunder storms.
According to weather reports, and the Empire State Building website, lightning strikes the empire state building about 23 times a year on the average.

so just sub in the info you are provided with.
266.45x10^3=0.5×100xv^2
V is 73.
Answer:
<em>faster and at a higher luminosity and temperature.</em>
Explanation:
A protostar looks like a star but its core is not yet hot enough for fusion to take place. The luminosity comes exclusively from the heating of the protostar as it contracts. Protostars are usually surrounded by dust, which blocks the light that they emit, so they are difficult to observe in the visible spectrum.
A protostar becomes a main sequence star when its core temperature exceeds 10 million K. This is the temperature needed for hydrogen fusion to operate efficiently.
Stars above about 200 solar masses (Higher mass) generate power so furiously that gravity cannot contain their internal pressure. These stars blow themselves apart and do not exist for long if at all. A protostar with less than 0.08 solar masses never reaches the 10 million K temperature needed for efficient hydrogen fusion. These result in “failed stars” called brown dwarfs which radiate mainly in the infrared and look deep red in color. They are very dim and difficult to detect, but there might be many of them, and in fact they might outnumber other stars in the universe.
That is why higher mass protostars enter the main sequence at a <em>faster and at a higher luminosity and temperature.</em>
I am not sure what you are asking but..: A series circuit is a circuit with 2 or more bulbs or lights to light. In a series circuit when you take out one bulb (or one goes out) the rest go out as well. A parallel circuit is still multiple lights, but because of the way it is set up makes it so when you take out one bulb (or one goes out) all of the rest stay lit.
Net force = mass × acceleration
F= ma
a = F/M
a = 6f/2m
a= {3f/m} ms-²
