Answer:
Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.
Explanation:
Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.
<u>Mathematically:</u>
where
R = resistance of the conductor
i.e.
- When resistance is held constant the current is directly proportional to the voltage.
Other form of the equation is:
- For a constant current the voltage is directly proportional to the resistance of the conductor.
- For constant voltage the current is inversely proportional to the resistance of the conductor.
The geologic record is the history of Earth as recorded in the rocks that make up its crust. Rocks have been forming and wearing away since Earth first started to form, creating sediment that accumulates in layers of rock called strata. The way these strata are arranged and what fossils are in them give scientists clues about what Earth was like billions of years ago.

A sound wave is the answer
This question is incomplete, the complete question is;
Car B is rounding the curve with a constant speed of 54 km/h, and car A is approaching car B in the intersection with a constant speed of 72 km/h. The x-y axes are attached to car B. The distance separating the two cars at the instant depicted is 40 m. Determine: the angular velocity of Bxy rotating frame (ω).
Answer:
the angular velocity of Bxy rotating frame (ω) is 0.15 rad/s
Explanation:
Given the data in the question and image below and as illustrated in the second image;
distance S = 40 m
V
= 54 km/hr
V
= 72 km/hr
α = 100 m
now, angular velocity of Bxy will be;
ω = V / α
so, we substitute
ω = ( 54 × 1000/3600) / 100
ω = 15 / 100
ω = 0.15 rad/s
Therefore, the angular velocity of Bxy rotating frame (ω) is 0.15 rad/s
