Newton's third law states "for every action, there is an equal and opposite reaction."

What this is pretty much saying is that for every action, there is a consequence. One force connects and triggers another.

Newton's third law says, " For every action, there is an equal and opposite reaction."

The magnitude of action and reaction are equal but the direction is opposite.

A 69 g particle is moving to the left at 25 m/s . How much net work must be done on the particle to cause it to move to the righ

LekaFEV [45]

Answer:11.59 J

Explanation:

Given

mass of Particle $m=69 gm$

Initially Particle moves towards left $v_1=25 m/s$

Final velocity of Particle is towards Right $v_2=31 m/s$

According to Work Energy theorem

Work done by all the Forces=change in Kinetic Energy

Work done by Force $=\frac{mv_2^2}{2}-\frac{mv_1^2}{2}$

$W=\frac{69\times 10^{-3}}{2}\left [ 31^-25^2\right ]$

$W=\frac{69\times 10^{-3}}{2}\left [ 961-625\right ]$

$W=11.59 J$

If the SAME person does a cannonball from these different heights, which height will produce the biggest SPLASH? WHY?

sveta [45]

Answer:

the impact on the water varies from different heights, therefore the mass stays the same, yet the force on the water increases from a higher height. A taller height will produce a bigger splash!

Daniel wants to find out if he can notice the difference in light intensity when he adds some lit candles to a set of 50 lit can

nexus9112 [7]

Answer:

Explanation:

The light intensity may be defined as the strength of the light or the magnitude of its brightness that a source of light can produce.

The light threshold is the minimum intensity of the light that our eye can detect and the ability to adapt to darkness.

In the context, Daniel wishes to find if can notice the difference in the intensity of the light when he add 5 candles to the set of 50 candles.

He noticed that when he added 5 candles, he could notice the difference in the intensity and when he added less than 5 candles to the set of 50 candles he could not detect.

Thus, the difference threshold for Daniel to detect the change in the intensity of the light is 5 candles.
