Answer: C) the splitting of a nucleus released a large burst of energy
Explanation:
nuclear fission occurs when an isotope (usually unstable) is hit with particles such as neutrons and splits, resulting in an extreme burst of energy.
for instance, the atomic bombs developed by the U.S. during WWII were products of nuclear fission in which plutonium-239 and uranium-235 were struck by a neutron that hit either nucleus of either isotope. The result was the neclus split into fragments that released huge amounts of energy snd the fission process became self-sustaining as neutrons produced by the splitting nucleus hit other nuclei and produce more fission, causing a chain reaction.
Answer:
No, in science their meanings are not the same as their everyday meanings.
Explanation:
In Science, Precision and Accuracy are defined as,
Accuracy:
Accuracy is the value which is closest to the known or standard value.
Precision:
While, Precision is the value of closeness of two measured values to each other.
Example:
Let suppose in Chemistry Lab you weight an object as 50 g. While the actual weight of that object is 30 g. It means your reading is not accurate.
On second measurement you find that the object weight is 31 g. This time your reading is not precise.
Answer:
5.68 × 10⁴ mL = 56.8 L
Explanation:
Volume is defined as the amount of three-dimensional closed space. The SI unit of volume is cubic metre which is denoted by the symbol m³.
According to the metric system, other units of volume include: litre (L), millilitre (mL) and cubic centimetre (cm³).
Since, 1 mL = 0.001 L = 10⁻³ L
Therefore, 5.68 × 10⁴ mL = 5.68 × 10⁴ × 10⁻³ L = 5.68 × 10 L = 56.8 L
5.68 × 10⁴ mL = 56.8 L, has three non-zero significant figures.
