A police officer uses a radar gun to determine the speed of a car. A specialized radar gun uses ultraviolet light to determine s
lakkis [162]

Answer:

Radio Waves

Explanation:

Radio wave is a type of electromagnetic radiation notorious for their use in technologies used for communication like air traffic control, mobile phones, televisions and remote-controlled toys. Radio waves have the longest wavelength in the electromagnetic spectrum and are easily transmitted through air.

A radar gun uses radio waves to tell how far away an object is. To do that, the radar tool emits a focused radio wave and listens for any echo. If there is an item, say a car within the route of the radio wave, it's going to replicate some of the electromagnetic energy, and the radio wave will return to the radar gun. Radio waves flow via the air at a steady pace, so the radar gun can calculate how far the object is based totally on how long it takes the radio signal to return.

A small bead with a positive charge q is free to slide on a horizontal wire of length 4.5 cm . At the left end of the wire is a
-Dominant- [34]

Answer:

1.5cm

Explanation:

The place where the bead will come to rest is the place where the force between the left charge and the bead is the same, but in opposite direction, as he force between the right charge and the bead.

F_{left} = F_{right}\\K\frac{q_{left}*q_b}{r_{left}^2} =K\frac{q_{right}*q_b}{r_{right}^2}

Also:

r_{left}+r_{right}=0.045m\\r_{right} = 0.045m-r_{left}

q_{left}= q\\q_{right}=4q

So, we replace and simplify. Notice that the charges and the Coulomb constant will cancel:

K\frac{q_{left}*q_b}{r_{left}^2} =K\frac{q_{right}*q_b}{r_{right}^2}\\\frac{q*q}{r_{left}^2} = \frac{4q*q}{(0.045m-r_{left})^2}\\(0.045m-r_{left})^2 =4r_{left}^2\\0.002025m - 2*0.045r_{left} + r_{left}^2 = 4r_{left}^2\\3r_{left}^2 + 0.09r_{left} - 0.002025m = 0

r_{left} = \frac{-(0.09)+-\sqrt{(0.09)^2-4*(3)(-0.002025)}}{2(3)}\\ r_{left} = 0.015m| -0.045m

But the only solution that would place the bead on the wire is 0.015m or 1.5cm, so this is our answer.

Calculate the vertical distance an object dropped from rest would cover in 12 seconds if it fell freely without air resistance
Nikolay [14]

Answer:

705.6 m

Explanation:

time, t = 12 sends

initial velocity, u = 0

Acceleration due to gravity, g = - 9.8 m/s^2

As the object is falling freely so the initial velocity is zero.

Let the distance traveled by the body is h in time t  = 12 s.

Use second equation of motion

h = u t - 1/2  gt^{2}

Ad the distance is downwards so take it as negative

So, -h = 0 - 1/2\times 9.8 \times 12 \times 12

h = 705.6 m

Thus, the distance traveled in 12 second is 705.6 m

Find the kinetic energy of a ball of mass 200 grams moving at a speed of 20 m/s.​
DedPeter [7]

Answer:

40KJ

Explanation:

m=200g

V=20m/s

Ek=?

Ek=(m*V²)/2

Ek=(200*20²)/2

Ek=(200*400)/2

Ek=80 000/2

Ek=40 000 J =40KJ
