Answer:
a. Volts = current x resistance
Explanation:
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.
Hence, Ohm's law gives the relationship between voltage, current and resistance of an electric circuit.
d = speed x time
distance = 29 x 30
distance = 870m

Answer:
False.
Explanation:
Yes the magnitude of a vector is always positive , but a vector consists of
when two vectors are added their direction may be opposite to each other For example-

,
then their resultant

This resultant vector's x and y component equal to y and x component of vector b so its magnitude will be equal to magnitude of vector b.
Therefore, the resultant magnitude not necessary equal to the magnitude of either vector.
