A truck accelerates 2 m/s2 when it is empty. If the truck is filled so that it has twice the mass and the same amount of net force is applied, how much will the truck accelerate?8 m/s2
1 m/s2
4 m/s2
2 m/s2

Answers

Answer :

a = 1 m/s^2

Explanation:

Given information

Net force is a constant

The mass of the truck is $m_(o)$

Initial acceleration $a_(o)$ = 2 m/ $s^(2)$

The mass of the truck is increased twice as much

$F_(net)= m_(o) a_(o)$ = ma

$F_(net)= m_(o) a_(o)$ = $2m_(o)$ a

a= $\frac{a_(o) } {2}$

a = 2/2

a = 1 m/ $s^(2)$

You would need a bigger force to act upon the object

IWhat is your mass in kilograms of you weigh 120 pounds?

Answers

One pound is (around, actually it's a little more, but you have to round it down to make the number practically usable) 0.45 kilograms, so 120 pounts is 120* 0.45, which is around 54kg.

The portion of a light ray that falls on a surface is a/an A. reflected ray.
B. diffuse reflection.
C. specular reflection.
D. incident ray.

Answers

So we want to know what is a light ray that falls on a surface. The incident ray that fallls on a surface can then fe reflected, refracted or transmitted. The angle in which the incident ray is must be the same as the angle of a refracted light ray. So the correct answer is D.

d. incident ray, i just took the test yesterday

How do stars locate in the galactic disk orbit the galactic center?

A. they do not orbit the galactic center.
B. they move in the circular orbits around the galactic center.
C. they bob up and down as they orbit the galactic center.
D. they orbit in elliptical orbits with random orientations.

Answers

Final answer:

The center of the Milky Way is in the direction of the constellation Sagittarius. The stars in the galactic disk move in a rosette pattern as they orbit the galactic center, which is neither completely circular nor random elliptical orbits.

Explanation:

The galactic center of the Milky Way is located in the direction of the constellation Sagittarius. The stars in the galactic disk orbit the galactic center much like how planets in our solar system orbit the sun. The movement of these stars is not completely circular, nor do they bob up and down or orbit randomly in elliptical paths. The actual orbit is more like a rosette pattern, not perfect circles but also not random orientations.
