Simple machines make work easier by multiplying, reducing, or changing the direction of a force. The scientific formula for work is w = f x d, or, work is equal to force multiplied by distance. Simple machines cannot change the amount of work done, but they can reduce the effort force that is required to do the work

Answer:
Last option in the list of possible answers, with U235 and n (neutron) in the left (originators) of the reaction diagram.
Explanation:
Uranium 235 (which is a fissile isotope of uranium) plus slow neutrons is what produce the chain reaction that feeds nuclear reactors.
stimulus. Because its the only thing I can really think of that evokes.
Answer:
5.10 m
Explanation:
Given that:
Initial velocity given to the ball, v = 10 m/s
Mass of the ball, m = 0.3 kg
Acceleration due to gravity, g = 9.8m/
To find: The height upto which the ball will go = ?
Solution:
Initially, the ball will have kinetic energy and at top point the velocity will be zero, it will have only potential energy due to height.
Formula for kinetic energy and potential energy:

Applying conservation of energy principle:

Putting the values of v and g to find h:

<em></em>
<em>The ball will go 5.10 m high</em>.
