D)four cells that each have half as many chromosomes as the parent cell
Explanation:
It is given that,
Length of the string, l = 2 m
Mass of the string, 
Hanged mass in the string, 
1. The tension in the string is given by :
T = 1.96 N
2. Velocity of the transverse wave in the string is given by :
m = M/l
v = 28 m/s
Hence, this is the required solution.
Answer:
A- series B- parallel
Explanation:
In order to measure current in a circuit, the multi-meter needs to be placed in series with the circuit while when measuring voltage, the multi-meter needs to be placed in parallel with the circuit.
It should be however noted that the same current flows in a series connected circuit and same voltage flows through loads connected in parallel. The ammeter is placed in series with the load to ensure that same value of currents is flowing in both the ammeter and loads(since same current flows in series connected circuit elements and all the amount of voltage must be made to appear on the load for the current to be measured accurately.
Voltmeter is connected in parallel to the load due to high value of current possessed by the voltmeter. The parallel connection will cause the current flowing through the voltmeter to reduce to zero so that it won't have effect (increase) on the amount of current initially on the resistor thereby measuring the exact amount of voltage on the load.
Answer:
C. Heat
Explanation:
HEAT is energy that is transferred due to a difference in temperatures.
I hope it helps! Have a great day!
When naming isotopes, the number beside it indicates the mass number. Now mass number is the sum of protons and neutrons.
We know that the mass number of a stable Sulfur atom is 32, so we can rule out C as an isotope. The atomic number of Sulfur is 16 and that means that there are 16 protons. Now if we subtract 16 from 33, then that means there are 17 neutrons. So we can rule out D.
Phosphorus on the other hand has an atomic number of 15. If we subtract 15 from 31 we will have 16. That means that Phosphorus-31 has 16 neutrons.
The answer would then be A. Phosphorus 31.
