um carro com uma velocidade de 80 km\h passa pelo km 240 de uma rodovia as 7:30. a que horas este carro chegara a proxima cidade, sabendo-se que a mesma esta situada no km 300 dessa rodovia?

Answers

Answer 1

Answer: From km 240 to km 300 there are 60 km.

The time to travel 60 km at 80km/h is t = d/V = 60km / 80 km/h = 3/4 h.

That is 45 minutes. Then the car will arrive at 7:30 + 45 min = 8:15.

What is the correct formula for work?a. Work = force / time
b. Work = force * distance
c. Work = force / distance
d. Work = mass * acceleration

Answers

The correct formulafor work is option B. Work = force * distance.

What is Work and what is its formula?

In physics, the term "work" has a specific meaning.
Work, in physics, occurs when a force acts on an object to move it some distance from the start point (also called displacement).
Work is calculated as the force times the distance.
In other words, work is equivalent to the application of a force over a distance.
The amount of work a force does is directly proportional to how far that force moves an object.
The work formula is w = F × d.
F is the force, d is the distance, and w is the work.

Ski lift carry people along 150 m cable up the side of a mountain. Riders are lifted a total of 75 m in elevation. What is the ideal mechanical advantage of the ski lift?

Answers

Ideal Mechanical Advantage (IMA) can be found by using the formula:

IMA = ID/OD

ID = Input Distance

OD = Output Distance

In the question, we are given:

ID = 150

OD = 75

Now, solve the expression with what we have.

IMA = 150/75

IMA = 2

Therefore, the IMA is 2.

A water wave travels across a 42-meter wide pond in 7.0 seconds. The speed of the wave is _____. 292 m/s 49 m/s 6.0 m/s 0.17 m/s

Answers

   Speed = (distance covered) / (time to cover the distance).

The speed of anything that covers 42 meters in 7 seconds is

   (42 meters) / (7.0 seconds)

   = (42 / 7.0) (meters/second)

   =   6.0 m/s .

Answer:

6.0 m/s

Explanation:

A water wave travels across a 42-meter wide pond in 7.0 seconds. The speed of the wave is _____.

292 m/s

49 m/s

6.0 m/s

0.17 m/s

All particles made of quarks are called _____.electrons

Answers

All particles madeup of two or more quarks held together by a force are called ; ( C ) Hadrons

What are Hadrons ?

Hadrons are subatomic particles which are made of two or more quarks which are held firmly by a force similar to electric force. An example of Hadron is Baryon which contains three quarks which are held closely together.

Hence we can conclude that All particles made of quarks are called Hadrons
