Answer:
750,000
Explanation:
I just looked it up on Google lol. You apparently multiple by 1000
Hope this helps :p
Answer:
21.9 seconds
Explanation:
lets say the speed of sound at room temp 343m/s and one kilometer is 1000 meters. so 7.5 kilometers is equal to 7500 meters and we divide this number by 343 and we get 21.8 seconds
Answer:
Fusion
Fission
Explanation:
The first problem describes a nuclear fusion process. In this process;
- small atomic nuclei combines to form a larger one.
- it is accompanied by a large release of energy
- this energy provides the needed temperature to set up another light nuclei to fuse.
The second problem describes nuclear fission,
- a heavy nuclide is bombarded with a neutron.
- the product formed becomes unstable and subsequently breaks down.
- This leads to a series of chain reactions until stability is attained.
Answer:
The lungs are lateral to the heart.
Explanation:
Answer: Gravitational force
Explanation:
The law of universal gravitation states that the force of attraction (F) between two bodies is directly proportional to their masses m1 and m2, and inversely proportional to the square of the distance (R) seperating them.
Thus, it is expressed mathematically as:
F = Gm1m2/R²
where,
- G is the gravitational constant with a value of 6.7 x 10^-11 Nm2/kg2
- F is the Gravitational force (unit is Newton)
- m1 and m2 are the masses of the two bodies (unit is kilograms)
- R is the distance seperating the two bodies. (unit is metres)
Thus, the formula f=G(m1m2)/R² help us find the gravitational force.
