Write the values of the 9s in 402,999

Answer:

2.6 seconds

Explanation:

You have to divide the distance by the velocity to find the time:

46/18 = 2.55 ≈ 2.6 seconds

The answer you are looking for is approximately 2.6 seconds.

Solution/Explanation:

To get the correct answer, you must divide the distance and velocity.

This means that 46÷18=2.5556.

2.5556≈2.6.

So, therefore, the final answer is approximately 2.6 seconds.

I hope that this has helped you. Enjoy your day, and take care.

Answer:

700 hz

Explanation:

Answer:

At t = 1.6 sec., the man has jogged 1.76m.

From that point on, the dog closes in on the man at the speed of 3.8 - 1.1 = 2.7m/s.

The time for the dog to catch the man is therefore t = 1.76/2.7 = .65s.

The man will have jogged .717m further for a total distance of 2.477m.

The dog will have traveled .65(3.8) = 2.477m.

Explanation:

<333

If A man jogs at a speed of 1.5 m/s. His dog waits for 2.5 s and then takes off running at a speed of 2.6 m/s to catch the man, then they have to travel 8.85 meters each when the dog catches up with the man.

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

The unit of velocity is meter/second. It can also be represented by the infinitesimal rate of change of displacement with respect to time.

The generally considered unit for velocity is a meter per second.

As given in the problem If A man jogs at a speed of 1.5 m/s. His dog waits for 2.5 s and then takes off running at a speed of 2.6 m/s to catch the man,

When both the man and dog meet the distance covered by them would be equal.

Let us assume the time taken to catch up is t seconds when the dog takes off,

distance covered by man = distance traveled by the dog

1.5 ×t + 1.5×2.5  = 2.6 ×t

1.1t = 3.75

t = 3.75/1.1

 = 3.40 seconds

Distance traveled during the catch-up = 3.40 ×2.6

Distance traveled during the catch-up = 8.85 meters

Thus, they have to travel 8.85 m each when the dog catches up with the man

Answer:

c

Explanation:

A shift inward of the production possibilities curve signifies that: C. The available production resources have decreased, so potential production levels will decrease.

A production possibilities curve (PPC) is also referred to as production possibilities frontier (PPF) and it can be defined as a curve that illustrates the maximum (best) combinations of two (2) products which can be produce in an economy if they both depend on these two (2) main factors;

Basically, the production possibilities curve (PPC) illustrates the maximum combinations of goods that are available with fixed technology and resources.

Furthermore, an inward shift of the production possibilities curve (PPC) signifies that the available resources used for production have decreased, so potential production levels would also decrease.

Answer:

Explanation:

There are many laws in physics, that started out as theories and became scientific truths only after an experiment was performed that confirmed that the theory was true.

One of the most famous theories was the guess that the gravitational Force was a constant amount that depended on mass and distance. It was incredibly difficult to prove because the with large masses and small distances, the force is quite small.

Newton proposed the existence of the gravitational force in 1687 and Cavendish found its precise truth in 1798 -- 111 years after Newton said it was so.

Newton proposed a theory. Cavendish proved it to be a law later. Even then, Einstein proposed the modern law.

The gravitational force F between two bodies of masses M and m, separated by a distance R, has a magnitude of

F = GMm/R ²

We're given that

F₁ = Gm₁m₂/r ²

and

F₂ = G (2m₁) (4m₂)/(2r )²

Now,

F₂ = G (2m₁) (4m₂)/(2r )²

F₂ = 8/4 Gm₁m₂/r ²

F₂ = 2 Gm₁m₂/r ²

F₂ = 2 F₁

so n = 2.

Variables - Initial position, Final position, Distance between Positions, Time.

Instruments - Ruler (Distance between Positions), Chronometer (Time)

Average Velocity is equal to the change in Position divided by Time. Since Incline is a Straight Line, then Position Change and Traveled Distance are the same. In this case, we need to define Initial and Final Position of the marble, and then we have to measure the distance between these Points.

Distance between Initial and Final Position can be measured by a Ruler, whereas Time can be measured by a Chronometer.

In a nutshell, Initial and Final Position and Time are variables needed to be measured. Besides, Distance between Initial and Final Position can be found by means of a Ruler, and Time is found with the help of a Chronometer.

Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.

For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.

Answer:

relative motion is the motion of an object compared to that of another object.for example two cars driving in the same highway in the same direction.

Answer:

The north part of the compass needle is attracted to the magnetic south pole of Earth, which is also known as the geographical north pole.  When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
