Answer:

Hence, total number of bytes in 10 computer is 2 × $10^{11}$ Bytes.

Explanation:

One computer have 20 GB hard drive.

1 GB = $10^{9}$ Bytes

20 GB = 20 × $10^{9}$ Bytes

Thus, one computer has 20 × $10^{9}$ Bytes.

There are 10 computers in the computer lab that each have 20 GB hard drives.

So, total Bytes on 10 computer is given by,

1 computer = 20 GB

10 computer = 200 GB

Thus 10 computer have total 200 GB.

As given above,

20 GB = 20 × $10^{9}$ Bytes

This is number of bytes in 1 computer.

So, in 10 computer number of Bytes are as follows,

10 × 20 GB = 10 × 20 × $10^{9}$ Bytes

200 GB = 200 × $10^{9}$ Bytes

200 GB = 2 × $10^{11}$ Bytes

Hence, total number of bytes in 10 computer is 2 × $10^{11}$ Bytes.

What is the period of a pendulum that takes 5 seconds to make a complete back and forth vibration

dezoksy [38]

Answer:

Explanation:

-A period is the time it takes to make one full back-and-forth swing.

-A period is calculated as the time taken for a complete swing divided by one cycle:

$T=t/1c\\\\=5s/1\\\\=5s$

Hence, the period of the pendulum is 5s

You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you

Paraphin [41]

Given :

You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you travel 250 miles in an hour and a half.

To Find :

Average speed.

Solution :

We know, average speed is given by :

$v=\dfrac{\text{Total distance covered}}{\text{Total time taken}}\\\\v=\dfrac{200+250}{3+1.5}\ miles/hr\\\\v=\dfrac{450}{4.5}\ miles/hr\\\\v=100\ miles/hr$

Therefore, average speed of the journey is 100 miles/hr.

Hence, this is the required solution.

A 0.12 g honeybee acquires a charge of +24pC while flying. The earth's electric field near the surface is typically 100 N/C, dow

shusha [124]

Answer:

150000000

$\dfrac{F_e}{F_g}=0.00000203873598369$

49050000 N/C

Explanation:

q = Charge = 24 pC

m = Mass of honeybee = 0.12 g

E = Electric field = 100 N/C

g = Acceleration due to gravity = 9.81 m/s²

$1\ C=6.25\times 10^{18}\ electrons$

Number electrons is

$n=24\times 10^{-12}\times 6.25\times 10^{18}\\\Rightarrow n=150000000$

The number of electrons added or removed was 150000000

Force is given by

$F_e=Eq\\\Rightarrow F_e=100\times 24\times 10^{-12}\\\Rightarrow F_e=2.4\times 10^{-9}\ N$

The ratio is

$\dfrac{F_e}{F_g}=\dfrac{2.4\times 10^{-9}}{0.12\times 10^{-3}\times 9.81}\\\Rightarrow \dfrac{F_e}{F_g}=0.00000203873598369$

The ratio is $\dfrac{F_e}{F_g}=0.00000203873598369$

Balancing the forces we get

$Eq=mg\\\Rightarrow E=\dfrac{mg}{q}\\\Rightarrow E=\dfrac{0.12\times 10^{-3}\times 9.81}{24\times 10^{-12}}\\\Rightarrow E=49050000\ N/C$

The electric field required is 49050000 N/C

What mechanism of energy is transferred by mass motion of fluid from one region of space to another?

lora16 [44]

Convection, because it is the process of heat transfer from one location to the next by the movement of fluids. The moving fluid carries energy within it.
