These states ofwater are simply physical changes. It has stayed the compound H2O throughout all of them. It had changes in phases but it never changed to anything but water.
Answer:
A topographic map is a map that indicates the features of the land's surface, such as mountains, hills, and valleys. This is usually done with wavy lines that represent the curves and elevation of the land.
SI will always be in metric, so the answer is D. Meter.
Answer:
240 Ω
Explanation:
Resistance: This can be defined as the opposition to the flow of current in an electric field. The S.I unit of resistance is ohms (Ω).
The expression for resistance power and voltage is give as,
P = V²/R.......................... Equation 1
Where P = Power, V = Voltage, R = Resistance
Making R the subject of the equation,
R = V²/P.................... Equation 2
Given: V = 120 V, P = 60 W.
Substitute into equation 2
R = 120²/60
R = 240 Ω
Hence the resistance of the bulb = 240 Ω
Answer:
Ohms law state that the current I flowing through a metallic conductor is directly proportional to the potential difference V across its end, provided that all physical condition are kept constant i.e temperature
Explanation:
that is, V varies directly to I
Where,
V= potential difference in volt and
I = current in Ampere (A)
therefore,
V= IR and R is measured in ohm
