Answer:
F = 1015 N
Explanation:
Given that,
Mass of a ball, m = 0.145 kg
Initial speed, u = 20 m/s
Final speed, v = -15 m/s (as it moves in opposite direction)
The ball and bat were in contact for 5 ms
We need to find the force the bat applies to the bat. We know that,
F = ma
So, the bat will apply 1015 N force to the ball.
Work = force * distance
force = 100 N
Distance = 5m
work =100 N* 5m
=500 J
<span>Let's put it this way. Say you have a killer-whale and a penguin. Killer-whales are major predators to penguins. Now, say the killer-whale population increases. The penguins would be eaten more by the killer-whales, then causing a population decrease for the penguins. If the population decreases, they're won't be enough penguins, and they most likely will become extinct, as well as causing a population decrease for the killer-whales as well. Whereas, vis versa, they're were a killer-whale population decrease. The penguins would be less hunted, therefore, creating a population increase for the penguins.</span>
Answer: Scanning Tunneling Microscope
Explanation:
The answer is, of course, the greatest Star Trek fan art imaginable: images literally built out of individual atoms. The images are the work of IBM scientists who created the unique artwork with a two-ton machine called the Scanning Tunneling Microscope that moves single atoms across a tiny piece of copper.
1. I think it's the trails left by an electron as it moves around the nucleus.
2. The atomic number is the number of protons so it is 8.
3. It's mass is lowered but it is still the same element.
