An open 1-m-diameter tank contains water at a depth of 0.5 m when at rest. As the tank is rotated about its vertical axis the ce

Morgarella [4.7K]

Answer:

Angular velocity (w) = 8.86 rad/s

Explanation:

Angular velocity (w) = $\sqrt{} 4ghi/R^{2}$

g= 9.81 m/s

R= 0.5

hi (initial depth) = 0.5m

Hence= $\sqrt4* 9.81* 0.5/0.5^{2}$ = 8.86 rad/s

A transformer has 18 turns of wire in its primary coil and 90 turns in its secondary coil. An alternating voltage with an effect

Fantom [35]

Answer:

$I_s=5.8A$

Explanation:

Not considering any type of losses in the transformer, the input power in the primary is equal to the output power in the secondary:

$P_p=P_s$

So:

$V_p*I_p=V_s*I_s$

Where:

$V_p=Voltage\hspace{3}in\hspace{3}the\hspace{3}primary\hspace{3}coil\\V_s=Voltage\hspace{3}in\hspace{3}the\hspace{3}secondary\hspace{3}coil\\I_p=Current\hspace{3}in\hspace{3}the\hspace{3}primary\hspace{3}coil\\I_s=Current\hspace{3}in\hspace{3}the\hspace{3}secondary\hspace{3}coil$

Solving for $I_s$

$I_s=\frac{V_p*I_p}{V_s}$

Replacing the data provided:

$I_s=\frac{110*29}{550} =5.8A$

Quartz, SiO2, contains 46.7% silicon by mass. What mass of silicon is present in 348 g of quartz? You must show your work.

anastassius [24]

Answer:162.516 gm

Explanation:

Given

Quartz contains 46.7 % silicon by mass

i.e.Silicon is 46.7 % by mass

Total mass of Quartz m=348 gm

46.7% of 348 gm

$=\frac{46.7}{100}\times 348=162.516 gm$

Answer:

4 : 1

Explanation:

<h3><u>Pulse rate</u></h3>

Also referred as heart rate can be affected due to vigorous exercise, age, health. Normally the pulse rate of an adult is between 60 to 100 beats per minute. pulse rate: 80 bpm.

<h3><u>Breathing rate</u></h3>

The amount of oxygen taken in inside of our body from the air. Breathing rate is usually affected due to age. Normal breathing rate of an adult is between 15 to 24 breaths per minute. breathing rate: 20 bpm.

<h3><u>Ratio of breathing to pulse rate</u></h3>

pulse rate : breathing rate

80 : 20

4 : 1
