Two footballs (A & B) are thrown with the same amount of force. Football A has a greater mass. Describe the acceleration for

Sauron [17]

Newton's second law gives the relationship between force applied to an object, its mass and its acceleration:
$F=ma$
where F is the force, m the mass and a the acceleration.

A force F is applied to football A, whose mass is $m_A$ , and so the acceleration of this football will be given by (re-arranging the previous equation)
$a_A = \frac{F}{m_A}$

Similarly, the acceleration of football B will be
$a_B= \frac{F}{m_B}$
where $m_B$ is the mass of football B, and where the force F applied to the two footballs is the same.

Since football A has greater mass than football B, $m_A \ \textgreater \ m_B$ , if we compare the two previous formula we see that the acceleration of football B is greater than the acceleration of football A:
$a_B \ \textgreater \ a_A$
Therefore, if the same force is applied to the two footballs, football B will accelerate more than football A.

Which term describes the ability to process many things simultaneously?

stellarik [79]

Answer:

Parallel processing

Explanation:

It is a parallel processing because it involves the brain processing many part of problem simultaneously.

The brain natural mode of information involves performing many task .

It is also ability of the brain to simultaneously process incoming stimuli or signals of different quality. It is a part of brain's vision and divide what is seen into four major parts which are color, motion, shape, and depth.

A rocket is headed away from earth at a speed of 0.8c. the rocket fires a missile at a speed of 0.7c (the missile is aimed away

dsp73

To solve this problem, let us consider that the Earth is the origin, the initial reference point. Therefore the speed of rocket plus the missile would be 0.8 C

Now after the rocket had moved away from Earth, it fired a missile at a speed of 0.7 C. Now the reference made to this is relative to the rocket. We have established that our initial reference point is the Earth, therefore the real speed of the missile with reference to Earth is:

Speed of missile relative to Earth = 0.8 C + 0.7 C

Speed of missile relative to Earth = 1.5 C
