Answer:
It is one of the strongest materials in the world and can hold anything
Answer:
Explanation:
The 2 equations we need for this are
and
d = rt. First we need to find the velocity using the first equation, then we will plug it into the distance equation as the rate to find the time.
v = 331.5 + .606(20.0) I used 3 sig figs for the temp instead of the 1 found in 20.
v = 331.5 + 12.1 so
v = 343.6 m/s
Now, before we can find the time in seconds, we need to convert the distance to meters.
1.75 km = 1750 m:
1750 = 343.6t so
t = 5.09 seconds
Nuclear fusion- converts hydrogen atoms into helium. The by-product of nuclear fusion in the Sun's core is a massive volume of energy (solar energy) that gets released and radiates outward toward the surface of the Sun and then into the solar system beyond it.
Electron is a fundamental Particle by JJ Thomson so it was truly difficult to say that electron is a negative charge
Answer:
w = 1.766 Joule
Explanation:
Work = Force × Distance
In this case the Work done is stored in body as Gravitational potential energy, so , W = P. E. = mgh
Here m = 0.400 kg ( unit not given in the question if in other unit may be converted to Kg), g = 9.81 m/s² and h= 0.450 m
w = 0.400 kg × 9.81 m/s² × 0.450 m
w = 1.7658 kg m²/s² = 1.766 Joule or (Nm)
