An airplane flew from San Francisco to Washington, D.C. Approximately

Physics
1 answer:
Arada [10]3 years ago
5 0

Answer:

The solution is given below:

Explanation:

The computation of the speed is shown below

As we know that

Speed = distance ÷ time

where

distance is 2000 km

And, the time is 2.5 hours

SO, the speed is

= 2,000 ÷ 2.5

= 800 km/h

Now the distance would be the same i.e. 2,000 km

but the time is 2 hours

So, the speed is

= 2,000 km ÷ 2 hours

= 1,000 km/hr

The direction should be opposite to the first airplane

A pilot heads his jet due east. The jet has a speed of 475 mi/h relative to the air. The wind is blowing due north with a speed
oksian1 [2.3K]

Explanation:

a. The velocity of the wind as a vector in component form will be represented as v vector:

    v=30j

b.The velocity of the jet relative to the air as a vector in component form will be represented as u vector

    u=475i

c. The true velocity of the jet as a vector will be represented as w:

  w=u+v

  w=475i+30j

d.  The true speed of the jet will be calculated as:

    IwI=\sqrt{(475)^2+(30)^2}

    IwI=\sqrt{225625+900}

    IwI=\sqrt{226525}

    IwI=476 mi/h

e. The direction of the jet will be:

tita=tan^{-1}\frac{30}{475}

tita=tan^{-1}(0.0632)

tita=3.62degrees,or,N86.38degreesS

Formed through longshore drift<br> a. sea stack<br> b. sandbar<br> c. spit<br> d. headland
ANTONII [103]
<h3>Answer;</h3>

<em><u>Sand Spit or Spit </u></em>

<h3><u>Explanation;</u></h3>
  • <em><u>Long shore drift is the process that occurs when a sheet of water moves on and off the beach, in other words the swash and back swash</u></em>, thus capturing and transporting sediment on the beach back out to the sea.
  • <em><u>Sandbar</u></em> is normally formed when the sandspit stretches across a bay and connects the two sides. <em><u>Headland</u></em> is a high piece of land that extends out onto the sea. <em><u>Sea stacks </u></em>on the other hand results from the collapsing of the roof of the arch.

noname [10]
<h2>Answer:</h2>

The part of the electromagnetic spectrum usually used for communication is of  radio waves, infrared waves and microwaves.

But most common waves used in communication are radio waves.

<h3>Explanation:</h3>
  • Radio waves are used to transmit television and radio programmes.
  • While microwaves are used for mobile phones and Wi-Fi.
  • Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
  • Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz).
