Answer:
The final velocity of the object is, 
= 27 m/s
Explanation:
Given,
The acceleration of the object, a = 1000 m/s²
The initial displacement of the object, 
= 0 m
The final displacement of the object, 
= 0.75 m
The initial velocity of the object will be, 
= o m/s
The final velocity of the object, = ?
The average velocity of the object,
v = ( - )/ t
= 0.75 / t
The acceleration is given by the relation
a = v / t
1000 m/s² = 0.75 / t²
t² = 7.5 x 10⁻⁴
t = 0.027 s
Using the I equation of motion,
= u + at
Substituting the values
= 0 + 1000 x 0.027
= 27 m/s
Hence, the final velocity of the object is, = 27 m/s
Answer:
All of the above
Explanation:
The correct answer is option E (All of the above)
All the options are alternative source of energy.
The option given are not the traditional way (energy production from coal) of extracting energy as the loss of natural resources does not take place in these source of energy.
energy extracted from wind, solar light , hydrogen ,etc are the source of energy the alternative source of production of energy because do not exploit the natural resources, reduce the carbon emission and energy produced by them is clean energy.
Answer:
A
Explanation:
Basically all the other answer are opposites like Exercise is an effective way to relieve stress and lots of Stress does have Negative effects on people
This means that this substance has no fixed volume and can expand or shrink however it may want. An example is gas. Gas will always expand to fill up the space it is in.

<span>The five factors of production include land, labor,
capital, entrepreneurship, and knowledge. Land is considered as the primary because
these are the pre-existent resources readily available from nature however,
nowadays, these are already bought and passed down from generations. Capital is
the money used for the production which needs to be returned when one invests
on something. Labor is the person’s inputs which is very valuable. Entrepreneurship
is how the person transact according to how the people negotiate. And knowledge
is one of human’s invaluable efforts of giving the ideas.</span>
