What distance is covered by an airplane traveling at a velocity of 660 miles per hour in 3.5 hours?
N76 [4]

As per the question, the velocity of the airplane [v] = 660 miles per hour.

The total time taken by airplane [t] = 3.5 hours.

We are asked to determine the total distance travelled by the airplane during that period.

The distance covered [ S] by a body is the product of velocity with the time.

Mathematically distance covered = velocity × total time

                                                      S = v × t

                                                        = 660 miles/hour ×3.5 hours

                                                        = 2310 miles.

Hence, the total distance travelled by the airplane in 3.5 hour is 2310 miles.

morpeh [17]

Answer: The question has some missing details. The initial velocity given as u = -6.5i + 17j + 13k and the final velocity v = -2.8i + 17j -9.3k.

a) = (1.82i - 9.69k)m/s2

b) magnitude = 9.85m/s2

c) direction = 280.64 degree

Explanation:

The detailed and step is shown in the attachment.

What is the length of 0.005 mm in kilometers?
ZanzabumX [31]
The answer would be 5*10^9
.

If we divide \frac{5*10^9}{1*10^6}, it gives us 0.005!

Hope this helped! c:

An electron starts from rest in a vacuum, in a region of strong electric field. The electron moves through a potential differenc
Semenov [28]

Answer:

The kinetic energy is  KE  = 5.67*10^{-18} \ J

Explanation:

From the question we are told that

    The potential difference is  \Delta V  =  36 \ volts

       

The potential energy of the end  is mathematically represented as

        PEs  =  - q *  \Delta V

q  is the charge on an electron with a constant value of q =  1.60 *10^{-19} \  C

       substituting values

      PE  =  - 1.60*10^{-19} *  36

      PE  =  -  5.67*10^{- 18} \ J

Now from the law of energy conservation

     The PE_e    =  KEe

Where  KE _e is the potential  energy at the end

 So  

        KE  = 5.67*10^{-18} \ J

The  negative sign is not includes because kinetic energy can not be negative

Theo made a list of the properties of electromagnetic waves. Identify the mistake in the list. Electromagnetic Wave Properties 1
lapo4ka [179]

Answer:

Line 3 has a mistake.

Explanation:

Electromagnetic waves consist of oscillations of electric and magnetic fields that oscillate perpendicular to the each other. Therefore, Line 1 is correct.

Also, the fields in an electromagnetic waves oscillate perpendicular to the direction of propagation of the wave: therefore, they are transverse waves. So Line 2 is also correct.

Electromagnetic waves, contrary to mechanical waves, do not need a medium to propagate: so, they can also travel through a vacuum. Therefore, Line 3 is wrong.

Finally, all electromagnetic waves travel through a vacuum at the same speed, called speed of light:

c=3\cdot 10^8 m/s

So, Line 4 is also correct.
