Answer:
25 cm³
Explanation:
In the conversion of units, we know that are one cubic centimeters (cm³) in a milliliter (mL) .
1 milliliter = 1 cubic centimeter
25 milliliters = 25 cubic centimeters
Therefore, a volume of 25 milliliters is the same as a volume of 25 cubic centimeters.
This ultimately implies that, the volume of an object in milliliters is equivalent to its volume in cubic centimeters.
Answer:
3.222 ohms
Explanation:
If the total wire had a resistance of 29 ohms, when cut in three, each piece will have a resistance of 9.666 ohms.
As these three pieces (R1, R2 and R3) are now connected in parallel, the equivalent resistance R can be calculated using this equation:
1/R = 1/R1 + 1/R2 + 1/R3
1/R = 1/9.666 + 1/9.666 + 1/9.666
1/R = 3/9.666
R = 9.666/3 = 3.222 ohms
The resistance between A and B will be 3.222 ohms
Answer:
Less than.
Explanation:
We have the positive charged metal sphere and we have to determine the electric field at a point near to it. In order to find that if we bring the positive test charge at that point then as we know that "like charges repel" so their electric field lines will repel each other resulting in a weaker electric field.
However if we bring the negative test charge at that point then of course there will be attraction and also the the electric field lines will direct from the positive to negative resulting in a stronger electric field between them. So there will be larger electric field then before.
"In this case, It can be concluded that electric field will be less than it was at this point before the test charge was present."
It can be found in granitic and basaltic rock.
