<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>

A 1 kg object can be accelerated at 10 m/s^2. If you apply this same force to a 4kg object, what will its acceleration be?
AleksAgata [21]

Answer:

a2 = 2.5~m/s^2

Explanation:

<u>Mechanical Force</u>

According to the second Newton's law, the net force F exerted by an external agent on an object of mass m is:

F = m.a

Where a is the acceleration of the object.

Assume we apply some given force F to an object of m1=1 Kg that produces an acceleration a1=10 m/s^2, then:

F = m1.a1

The same force F is now applied to a second object m2=4 Kg that produces an acceleration a2, then:

F = m2.a2

Dividing both equations:

\displaystyle 1=\frac{m1.a1}{m2.a2}

Solving for a2:

\displaystyle a2=\frac{m1.a1}{m2}

Substituting values:

\displaystyle a2=\frac{1*10}{4}

a2 = 2.5~m/s^2
