Answer:
9800 Pa
Explanation:
Data: pressure-?
Force- mass ×acceleration
= 50× 9.8m/s^2
=490N
Area= 500cm^2=0.05m^2
pressure= force/ area
p=F/A
P= (490N)/( 0.05m^2)
=9800 Pa
Answer:
the star collapses and the outer layers explode as a 'supernova'.
Answer:
aphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun. When Earth is at its aphelion in early July, it is about 4,800,000 km (3,000,000 miles) farther from the Sun
Answer:
1 km = 1000 m
Explanation:
1 km = 1000 m
For uniform velocity motion; time taken = distance covered/average speed (t = d/v)
t = 1000/850 = 1.18 seconds
Nuclear fission is a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. And is used to spin a turbine to produce electricity.
