Answer: the correct one is E .systems; for example, hurricanes could be prevented from forming by artificial "reefs" of precisely shaped marine platforms
Explanation:
(A) The portion after the semi-colon (for instance, ... platforms) is not a complete sentence.
(B) The portion after the semi-colon (for example, ... forming) is not a complete sentence.
(C) Which ... "reefs" ... prevent forming is unidiomatic; from is needed between prevent and forming. Prevent appears in the present tense, illogically implying that the artificial reefs—which don't yet exist, according to the earlier part of the sentence—already prevent the formation of hurricanes.
(D) The construction such as artificial "reefs" illogically implies that artificial reefs are weather systems. Additionally, the use of can in the present tense (as opposed to could) illogically implies that the artificial reefs—which don't yet exist, according to the earlier part of the sentence—do already exist.
(E) CORRECT. The semicolon is properly used to separate two complete sentences. Could is correctly used to describe a hypothetical consequence.
Answer:
B is correct
Explanation:
Because the earth is rotating not the sun and moon
Answer:
R = 25 Ohms
Explanation:
Given the following data;
Voltage (p.d) = 15 V
Current = 0.6 A
To find the resistance of the wire;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the equation, we have;
R = 25 Ohms
