The voltage across resistor is 75 volts, because you can solve this using the ohm law.
Hope this help!!
Answer:
Explanation:
When two players are pulling the sled by same force inclined at 50 degree Angle so the net force is given as
now since the sled is moving with uniform speed so
now we have
(5 mi/hr) x (1hr/60min) x (10min) = 5 x 10 / 60 = <em>5/6 mile</em>
(5/6 mile) x (1,760 yd/mile) = <em>1,466 and 2/3 yards</em>
So, physical properties are what we can detect with our basic 5 senses or measuring tools, and the things that, when changed, dont actually change the chemical properties (like atoms and molecules). Lets take wood for an example: its brown, its solid, it can be big or small, it has a taste and smell, its boiling, freezing or melting point...
Chemical properties, on the other hand, are the things we can change with, for example, experiments and tools. Does it burn? Can it rust/oxidize? How does it react with other chemicals? Is it radioactive, or toxic? All of these are chemical properties you can probably answer.
Answer:
No, the mass of an object is always the same, even if a chemical reaction happens or the object becomes denser.
