Answer:
The atomic number increases by 1.
Explanation:
The beta minus decay is a process in which a neutron decays into a proton, emitting an electron and an anti-neutrino:

If this process occurs inside an unstable nucleus, we notice that:
- a neutron is converted into a proton, therefore
- the number of neutrons decreases by 1 and the number of protons increases by 1
Keep in mind that the atomic number of a nucleus corresponds to the number of protons it contains: therefore, since this number increases by 1, then the atomic number increases by 1.
A manufacturer of printed circuit boards has a design
capacity of 1,000 boards per day. the effective capacity, however, is 700
boards per day. recently the production facility has been producing 950 boards
per day. The design capacity utilization is (950/100) *100 = 95 %
Answer: The right answer is c.
Explanation:
The kinetic energy is defined as follows:
K = 1/2 mv²
If both cars are identical, this means that they have the same mass.
Also, we are told that the speed is also the same for both cars.
If they are going in opposite directions, their velocities have the same magnitude, but opposite signs.
But even though they have different signs, the square (which is the parameter relevant for kinetic energy calculations), is always positive, as any number, elevated to an even power, is positive.
So, we conclude that both cars have the same kinetic energy, in magnitude and in sign.
