The number of times something happens in one second is its "frequency".
Answer:
65 meters to the right.
Explanation:
the shark moves to the right 30 meters and then to the left 15 making his new placement 15. he then moved to the right 50 meters making his new placement 65 meters to the right.
Chemistry deals with the study of elements-- their properties, chemical reactions and their compounds. This science includes the study of how these elements or compounds are formed. The history of chemistry is divided to 4 periods.
Black Magic, Alchemy, Traditional Chemistry and Modern Chemistry comprised these periods.
How did the early chemists determine which of the substances are elements? Long time ago, chemists knew which substances could not be broken down and that mixtures are broken down through chemical means. Through the said process, they were able to identify which are elements from the substances they have tested.
Answer:
P = 375 Pa
Explanation:
The question says that,"If a force of 150N was applied in an area of 0.4m², what will be the precious exerted?"
We have,
Force, F = 150 N
Area, A = 0.4m²
We need to find the pressure exerted. We know that,
Pressure = forece/area
So,
So, the required pressure is equal to 375 pa.
charge needed= 169412 C
Explanation:
energy stored in the battery= 16 KWh= 16 (1000 W)(3600 s)= 5.76 x 10⁷ J
Energy stored is given by U= q V
q= charge
V= voltage= 340 V
so 5.76 x 10⁷ = q (340)
q= 169412 C
