Physics
1 answer:
MA_775_DIABLO [31]3 years ago
4 0

Answer:

Bad

Explanation:

To an ordinary person the atmosphere may look beautiful with the glowing sunlight, <u><em>but to an astronomer the atmosphere causes various effects which includes distortion, reddening,refraction etc, which causes a blur vision of space when viewed through a telescope.</em></u> This is problem NASA overcame and launched the Hubble space telescope in space.

A car traveling at 60 km/h will skid 30 m when its brakes are locked. if the same care is traveling at 180 km/h, what will be th
Flauer [41]
The first car travels at 60km/h and skid at 30m away from the starting point while another car is also traveling at 180km/h. Now, we need to solve for the skidding distance.
We assigned variables such as:
V1=60km/h
V2=180km/h
Skid1=30m
Skid2=?
We solve this by ratio and proportion method such as shown below:
V1/V2=skid1/skid2
60/180=30/skid2
skid2=(30*180)/60
skid2=90meters

Th answer is 90 meters.

The forces acting on a child sitting in a seat are described by the free-body diagram shown. What is the net force acting on the
r-ruslan [8.4K]

The net force is 0 N.

To find the total net force, all you need to do is add the forces.

So 100 + -100 = 0

Most of these questions are trick questions, but if you know Newton's laws of forces, then you should know that all forces should cancel out with each other.

Hope this helps!!!

At one point in space, the electric potential energy of a 15 nC charge is 42 μJ . Part A) What is the electric potential at this
Anastasy [175]

Answer:

Part A:

\rm 2.8\times 10^3\ Volts.

Part B:

\rm 5.6\times 10^{-5}\ J.

Explanation:

<u> Part A:</u>

  • Potential energy of charge at the given point, \rm U=42\ \mu J=42\times 10^{-6}\ J.
  • Charge, \rm q=15\ nC = 15\times 10^{-9}\ C.

The potential energy at a point due to a charge is defined as

\rm U=qV.

<em>where</em>,

V = electric potential at that point.

Therefore,

\rm V=\dfrac{U}{q}=\dfrac{42\times 10^{-6}}{15\times 10^{-9}}=2.8\times 10^3\ Volts.

<u>Part B:</u>

Now, if the charge at that point is replaced with \rm q_1 = 20\ nC = 20\times 10^{-9}\ C., then the electric potential energy at that point is given by

\rm U=q_1V = 20\times 10^{-9}\times 2.8\times 10^3=5.6\times 10^{-5}\ J.
