Explanation:
Given that,
Two resistors 4.5 Ω and 2.3 Ω .
Potential difference = 30 V
When they are in series, the current through each resistor remains the same. First find the equivalent resistance.
R' = 4.5 + 2.3
= 6.8 Ω
Current,
So, the current through both lightbulb is the same i.e. 4.41 A.
When they are in parallel, the current divides.
Current flowing in 4.5 resistor,
Current flowing in 2.3 ohm resistor,
In parallel combination, are brighter than bulbs in series.
Answer:
i think its 1-10 ´ 10-15 m
Explanation:
Answer:
m=ρV
V=LxWxD
V=4x10x2=80
m=2*80=160 grams
Explanation:
Mass is equal to density multiply by volume of object. Volume of rectangle pice can be calculated by multiplying all sides.
D. When a substance reacts with another substance, it shows its chemical property
Answer:According to the Equation (2), centripetal force is proportional to the square of the speed for an object of given mass M rotating in a given radius R.
Explanation:The Period T. The time T required for one complete revolution is called the period. For. constant speed. v = 2π r T holds.
