Answer:
V = 0.0723 volts = 72.3 milivolts
Explanation:
The emf induced in the rod is the motional emf due to the magnetic field. This motional emf can be calculated by the following formula:
where,
V = Motional EMF = ?
v = speed of rod = 12.5 m/s
B = Magnetic Field = 6.23 mT = 0.00623 T
l = Length of rod = 92.9 cm = 0.929 m
θ = angle between v and B = 90°
Therefore,
<u>V = 0.0723 volts = 72.3 milivolts</u>
Answer:
F = 400 N
Explanation:
Given,
The acceleration of the car, a = 8 m/s²
The mass of the passenger, m = 50 Kg
The force acting on a body is equal to the product of the mass and its acceleration
F = m x a newtons
Substituting the given values in the above equation,
F = 50 Kg x 8 m/s²
= 400 N
Hence, the force exerted by the person on the seat belt is, F = 400 N
The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. There are two different types of beta decay (positive and negative beta decays) they both occur simultaneously in order to move the atoms towards stability.
Answer:
A
Explanation:
The change in the system’s gravitational potential energy would be zero
Answer: Option A) Atoms to the left on the periodic table
Explanation:
The periodic table has metallic elements on the left side, semi-metal or metalloids in the middle, and nonmetallic elements of the right side.
Since, electronegativity of an atom tells of its power to attract electrons. Metals give off electrons rather than attract electrons like non-metals; thus, metals have the lowest electronegativity (with values less than 2.4 while nonmetal have high electronegativity values above 2.7
Infact, the element with the highest electronegativity is a non-metal (fluorine) while the element with the lowest electronegativity is a metal (potassium)
Thus, metallic atoms located on the left side of the periodic table have the lowest electronegativity
