What is the mass of an object if the density is 7.85g/l and the volume is 41.25ml
Blababa [14]
The density is the ratio between mass and volume. So the mass is the product between density and volume. But! You have to control the units of measure.

7.85 g/l = 0.00785 kg/l

41.25 ml = 0.04125 l

Mass = (0.00785) x (0.04125) = 0,00032381 kg ---> 0,32381 g

Orlov [11]

The best description of the process to draw the segment is B. b place a compass at one endpoint of the segment and trace an arc. do the same from the other endpoint. draw a line through the intersections of the arcs.

<h3>What is a segment bisector?</h3>

It should be noted that a segment bisector simply means a line to segment which cuts another line segment at the center but dividing the lines into two equal halves.

In this case, based on the information given, the best description of the process to draw the segment is to place a compass at one endpoint of the segment and trace an arc, do the same from the other endpoint. draw a line through the intersections of the arcs.

In conclusion, the correct option is B.

CONVERSION QUESTION
dlinn [17]

Answer:

615 μK/ms.

Explanation:

The conversion of 615mK/s to μK/ms can be obtained as follow:

1 mK/s = 10^-3 K/s

Therefore, 615mK/s = 615x10^-3 K/s

1K/s = 10^6 μK/s

Therefore,

615x10^-3 K/s = 615 x 10^-3 x 10^6 μK/s = 615x10^3 μK/s.

1s = 10^3ms

Therefore,

615x10^3 μK/s = 615x10^3 μK/ 10^3ms = 615 μK/ms.

Therefore,

615 mK/s = 615 μK/ms.
