Answer:
For the first equation, the work done would be 60 J, but if it is done with 30 N, it would have been 90 J.
Explanation:
it's actually pretty easy one you practice it for some time. W ( work done in joules ) = F ( force put onto the object in newtons ) * D ( distance traveled in meters ).
Because "acceleration" doesn't mean "speeding up". It means any change
in the speed or direction of motion.
An airplane speeding up, a bicycle slowing down, and a car going around a curve, are all doing accelerated motion.
A circle has no straight parts, so an object traveling in a circle is always changing
its direction. That means accelerated motion, even if its speed doesn't change..
When you increase the frequency of the waves (assuming amplitude is held constant), the energy of the waves will increase, while wavelength will decrease.. Increase the frequency the light goes toward violet, decrease it and it goes toward red.
Answer:
C
Explanation:
Its because electron does its thing with energy to
its orbital
Firstly, when we say precision, this means the level of detail of a number. On the other hand, significance means that how precise a number is written and accuracy is defined as how close the number is to an actual value. Significant figures represent the precision of a measurement and not its accuracy because when a measurement has a larger number of significant figures, it has a greater reproducibility <span>or precision because it has a smaller source of error in the estimated digit. Hope this answer helps.</span>
