Answer:
D. gravitational potential energy
Explanation:
The answer should be C. Both matter and energy because physical sciences are sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects.
Matter and energy fall in with chemistry
Answer:
Explanation:
The horizontal distance covered by the ball in the falling is only determined by its horizontal motion - in fact, it is given by
where
is the horizontal velocity
t is the time of flight
The time of flight, instead, is only determined by the vertical motion of the ball: however, in this problem the vertical velocity is not changed (it is zero in both cases), so the time of flight remains the same.
In the first situation, the horizontal distance covered is
in the second case, the horizontal velocity is increased to
And so the new distance travelled will be
So, the distance increases linearly with the horizontal velocity.
Malleable
Malleability
is a property of matter, that’s specializes in metals, in which these metals
can be bended, twisted or formed into a thinner sheets, and not being able to
shatter to pieces instead it can be formed into a new shape. Unlike the other
three, take for instance hardness. If a hard object such as wood for example
when used with an axe it breaks and it is lead to smithereens. Flammable like
is when applied to fire can dramatically explode when hit it obviously breaks.
The answer should be flammability
