Answer:

The planet will move from east to west for a couple of months in the night sky.

Explanation:

Retrograde motion is an optical effect due to the fact that Earth rotates more quickly than the planet that apparently has a retrograde motion in the sky.

For example, Saturn has a slower speed in its orbit around the Sun. That means that the Earth will pass it, and that will give the effect that the planet is moving backward. That same scenario can be seen between two cars on a highway, the faster car will see the slower car when it passes as it is moving for a short fragment of time in backward.

Remember that the planets in the night sky move from west to east, in the case of a planet with retrograde motion, it will move from east to west for a couple of months.

What are the sign and magnitude in coulomb's of a point charge that produces a potential of -1.50 V at a distance of 2.00 mm

Charra [1.4K]

Answer:

The sign of the charge is negative

The magnitude of the charge is 3.33 x 10⁻¹³ C

Explanation:

Given;

potential difference, V = -1.5 V

distance of the point charge, r = 2 mm = 2 x 10⁻³ m

The magnitude of the charge is calculated as follows;

$V = \frac{kq}{r} \\\\q = \frac{Vr}{k} \\\\where;\\\\k \ is \ coulomb's \ constant = 9\times 10^9 \ Nm^2/C^2\\\\q = \frac{-1.5 \times 2\times 10^{-3}}{9\times 10^9 } \\\\q = -3.33 \times 10^{-13} \ C\\\\Magnitude \ of \ the\ charge, q = 3.33 \times 10^{-13} \ C$

1. What do you need to change the momentum of a system?

N76 [4]

1. Momentum (P) is a equal to mass (M) times velocity (V). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (triangleP) over the change in Time (triangleT). And the change in momentum (triangleP) is also equal to the impulse (J)

Critical reasoning: We also use simulation to understand how the software would behave in the event of potential collisions. Giv

Using kinematic reasoning, the answers for the changes that can cause crashes are:

we can manipulate

The speed of the vehicles, especially that of the second car

he traffic light change time

Change some condition of the pavement after the first vehicle passes

Autonomous systems are systems that take a series of signals from the outside, analyze them and carry out actions according to how to handle them.

In that case you have two cars one behind the other at a short distance a traffic light with a yellow light is approaching.

Some parameters can be modified to cause the crash:

The car in front accelerates to pass the traffic light, but the traffic light changed to red, in this case if the car behind also accelerated, there may not be enough distance to stop and crash.

You can change the traffic light to green whereby the first car continues its speed, but the traffic light time changes very quickly to red, whereby the first car stops, but the car behind cannot stop.

The car behind accelerates to also pass the yellow light, but turns red and the first one crashes to a stop.

We change some condition of the pavement after the first vehicle passes, for example wetting the pavement, which decreases the coefficient of friction, consequently the second vehicle does not have time to stop.

We can appreciate that if there is not a good and fast communication between the two vehicles, it is easy for them to crash.

In conclusion, using kinematic reasoning, the answers for the changes that can test shocks are found:

The second vehicle increases speed and the first must brake sharply

A 4 kg bird has 18 joules of kinetic energy and is rolling 3 m/s. find the mass ?

vovangra [49]

KE = half of mass times squared speed
18 = 0.5 * mass * (3m/s)^2
18 = 4.5 mass
mass = 18 / 4.5 = 4 kg
