A truck travels due east for a distance of 1.9 km, turns around and goes due west for 8.7 km, and finally turns around again and

travels 3.0 km due east. (a) What is the total distance that the truck travels? km (b) What are the magnitude and direction of the truck's displacement?

Answer:

a) Total distance travelled = 1.9km + 8.7km + 3.0km = 13.6km

b) Total displacement = -1.9km + 8.7km-3.0km=+3.8km

Total displacement = 3.8km due west

Explanation:

a) Total distance travelled is a scalar quantity it is not affected by the direction it's only concerned with the magnitude.

Total distance travelled = 1.9km + 8.7km + 3.0km = 13.6km

b) Total displacement is a vector quantity it takes into consideration both magnitude and direction.

Taking west as positive and east as negative.

Total displacement = -1.9km + 8.7km-3.0km = +3.8km

Total displacement = 3.8km due west

Liula [17]

Responder:

<h3>150 Nm </h3><h3>Energía potencial </h3>

Explicación:

El tipo de energía que posee el objeto se conoce como energía potencial. <u>La energía potencial es la energía que posee un objeto, mi virtud de su posición. </u>

Energía potencial = masa * aceleración debido a la gravedad * altura

Dado que Force = masa * aceleración debido a la gravedad

Energía potencial = Fuerza * altura

Fuerza dada = 50N y altura = 3 m

Energía potencial = 50 * 3

Energía potencial = 150 Nm

As the mass of an object increases so does its gravitational force. <br> a. True <br> b. False
vichka [17]

Answer:

False

Explanation:

Gravity force is constant.

There some places on Earth that gravity has a variation, but in general, it is the same everywhere.

If you analyze the equation for the weight, which is the action of the gravity to mass, you'll see that W=mg, where m is the mass and g, is gravity.

If you increase the mass, what you are increasing is weight and not gravity.

How would you describe brass since it ia used in weapons, pipes, intruments and ect? A compound, Alloy, Element l, Or molecule?
Alik [6]
<span>Brass is an <u>alloy</u>. An alloy is a mixture of elements to form a unique material. Brass is a mixture of copper and zinc and the percentage of each element depends on the desired material. It has a higher malleability than bronze or zinc. Meaning that it can be bend easily into it desired form.</span>

A pendulum has a length of 2 m and a 30 kg mass hanging on the end. What is the period of the
anastassius [24]

Answer:

T = 2.83701481512 seconds

Explanation:

Hi!

The formula that you will want to use to solve this question is:

T = 2\pi *\sqrt{\frac{L}{g}  }

T--> period

L --> length of the pendulum

g --> acceleration due to gravity (9.8m/s^2)

since we know that the mass of the bob at the end of the pendulum does not affect the period of the pendulum, we can go ahead and ignore that bit of information (unless, of course, the weight causes the pendulum to stretch)

so now we can plug in our given info into the formula above and solve!

T = 2*pi * sqrt(2/9.8)

T = 2.83701481512 seconds

*Note*

- I used 3.14 to pi, if you need to use a different value for pi (a longer version, etc) your answer will be slightly different

I hope this helped!
