Hi there!
a.
The equation for centripetal acceleration is as follows:
Plug in the given values to solve:
b.
According to Newton's Second Law:
The acceleration is v²/r, so the net force is:
Multiply by the given mass:
c.
There is NO net force in the vertical direction since the object is NOT accelerating in the vertical direction (normal force and weight cancel).
Thus, the ONLY net force experienced by the object is in the horizontal direction and is EQUAL to the centripetal force.
The current that flows in the circuit is
(voltage applied to the circuit)
divided by
(net resistance of the circuit) .
The resistance of most circuits is constant. So this simple formula
shows that the current is directly proportional to the applied voltage.
If the applied voltage increases, so does the current.
Maybe the word could be converted?
Answer:
Option (D)
Explanation:
The chemical formula for normal water is H2O and the chemical formula for heavy water is D2O.
Where D is deuterium which is the isotope of hydrogen.
There are three isotopes of hydrogen.
1H1 it is called protium.
1H2 it is called deuterium.
1H3 it is called tritium.
Wait I think i have the same assignment as you I put C.
