  • Mass=15g
  • Density=0.789g/ml

\\ \bull\tt\dashrightarrow Density=\dfrac{Mass}{Volume}

\\ \bull\tt\dashrightarrow Volume=\dfrac{Mass}{Density}

\\ \bull\tt\dashrightarrow Volume=\dfrac{15}{0.789}

\\ \bull\tt\dashrightarrow Volume=19.01mL

Which type of graph most clearly show how a part or percentage relate to the whole
Bezzdna [24]

Circle graph is the type of graph which most clearly shows the part or percentage related to the whole.

<u>Explanation:</u>

Graphs are the easiest tool to show the change in a given dependent variable with respect to independent variable. The influence or the effects will be seen in the graphs.

There are different kinds of graph like circle graph, bar graph, line graph. Each of these have their own method of showing the change in the dependent variable. Among them, circle graph is the one which will help to show the percentage of each variable related to the whole.

The maximum speed around a level curve is 30.0 km/h. What is the maximum speed around a curve with twice the radius?
erastovalidia [21]

Answer:

When the radius is doubled, its speed will be 42.42 km/h.

Explanation:

Given that,

The maximum speed around a level curve is 30 km/h = 8.34 m/s

We need to find the maximum speed around a curve with twice the radius. The maximum speed of the object is given by :

v=\sqrt{\mu rg}............(1)

If radius is doubled, r' = 2r

The maximum speed is given by :

v'=\sqrt{\mu r'g}

v'=\sqrt{\mu (2r)g}..........(2)

Dividing equation (1) and (2) we get :

\dfrac{v}{v'}=\dfrac{1}{\sqrt2}

v'=\sqrt{2} v

v'=\sqrt{2}\times 30

v' = 42.42 km/h

So, when the radius is doubled, its speed will be 42.42 km/h. Hence, this is the required solution.

How many 176 ohm resistors are connected in series to get a current of 5 a on 220 v battey
Phantasy [73]
Total resistance = voltage / current = 220 / 5 = 44 ohms .

Even one 176-ohm resistor is too much.  The current through it is 1.25 A,
and more than one of them in series reduces the current even further.

Connecting them in <em><u>parallel</u></em>, however . . .

Four resistors of 176-ohms each, in <u>parallel</u>, have a net effective resistance
of 176/4 = 44 ohms ... exactly what you need to do the job.
