Gravitational potential energy=mass of object x gravitational field strength on earth(9.8 usually rounded to 10) x the height the object is held at
Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object
The
author’s feeling about a subject or topic, which is evidenced in word choice,
is called tone.
<span>They
could be literal meanings which are meanings explicitly given to the readers or
the person being told to. In this type of meaning, the person doesn’t need to
think the words too much or ponder on the meaning because they could easily
understand what the other person or the author implies. Meanwhile connotative
meanings are meanings using different figures of speech or symbolism that the
person still needs to think it over before knowing the actual meaning of the
word, sentence or story.</span>
Answer:
The answer is D.
Explanation:
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
Answer:
Explanation:
18 km / h
= 300 m / min
12 km / h = 200 m / min
distance travelled in 200 minutes = 300 x 200 = 60000 m
distance travelled in 50 minute in return journey = 200 x 50 = 10000 m
total distance travelled = 70000 m
total time = 250 minute
speed = 70000 / 250
= 280 m / min
= 16.8 km / h
Total displacement = 60000 - 10000 = 50000 m
total time = 250 min
velocity = 50000 / 250
= 200 m / min
= 12 km / h
