A 2550 gram box is pushed across the floor with a net force of 18 .0 N.
Aleks04 [339]

Answer:

The acceleration of the box across the floor is 7.0588 m/s^2

Explanation:

Given:

Mass of the box =  2550 gram

net force  acting on the box   =  18 .0 N.

To Find:

The acceleration of the box across the floor = ?

Solution:

Newton's 2nd Law of Motion states that the acceleration of an object as produced by a net force is "directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. "

Newton's Second Law formula is

F = m a

Where:

 F = the magnitude of the net force, in N

 m = the mass of the object, in Kilogram

 a = the acceleration of the object, in m/s^2

Now substituting the values, we get

18.0 =  a (2.55)     [since 2550 gram = 2.55 kg]

a = \frac{18.0}{2.55}

a =  7.0588 m/s^2

Which of the following occurs in a right lateral movement? A. The right condyle primarily rotates. B. The right condyle moves do
Thepotemich [5.8K]

Answer:

"The right condyle primarily rotates" occurs in a right lateral movement

Explanation:

The mandibular condyle is dynamically participate in endochondral ossification. The condylar cartilage is an significant development place in the mandible, paying to the elongation of the mandibular ramus. A protrusive energy happens when the mandible deviates (both of condyles) onward and descending along the slope of the articular eminence Happens though cutting and grasping food. This shift happens subsequently the condyle rotates. Regular motion of the mandible relies on appropriate role of the TMJ. Visibly, the preauricular area lies straight over the joint.
