Answer: A
Xenon 138
Explanation:
In the attached nuclear reaction, the sum of the mass number in LHS is
239 + 1 = 240
While the Atomic number = 54 + 0 = 54
The sum of the mass number in the RHS is 100 + 2(1) = 102
While the sum of the atomic number is
40 + 0 = 40
The mass number of the missing element is
240 - 102 = 138
While the Atomic number of the missing element is
94 - 40 = 54
Nuclear reaction at equilibrium, the mass number and the atomic number at LHS must be equal to RHS
The missing element is Xenon 138 with atomic number of 54
Therefore, when the Plutonium is bombarded with a neutron, the result of the reaction is the production of Zirconium 100 and Xenon 138 with the bombardment of two neutrons
I hope this will be helpful i made a bold assumption of speed of sound since it is not provided
Answer: 0.5 mm
Explanation: The smallest division that a common ruler has is 1 mm so any measurement taken is approximately accurate to a mm.
Uncertainty of any measuring instrument is the inaccuracy or lost of precision that occur due to its less divisions in an instrument
Uncertainty= Least Count /2
Uncertainty= 1 mm /2
Uncertainty= 0.5 mm
it means that measurement can be 2.3cm ± 0.5mm
Higher wind speeds would increase the amount of electricity generated by a wind turbine.
<h3>What is a power plant?</h3>
A power plant is an industrial structure that generates electricity. The majority of power plants are linked to the electrical grid.
Stronger winds produce greater power because they enable the blades to revolve more quickly. Greater mechanical and electrical power from the generator result from faster spinning.
Hence, higher wind speeds would increase the amount of electricity generated by a wind turbine.
