For a circuit find the total potential differences if two resistors

Physics
1 answer:
stepan [7]3 years ago
8 0

-- If the two resistors are connected in series, then they behave like a single resistor whose resistance is (R₁ + R₂) ohms.

-- For any resistance, the potential difference (volts) across the resistance is   V = (current) x (resistance) .

-- So in THIS circuit,  <em>V = I x (R₁ + R₂)</em> .

A 0.20-kg block rests on a frictionless level surface and is attached to a horizontally aligned spring with a spring constant of
solmaris [256]

Answer:

0.57 ms^{-1}

Explanation:

k = spring constant of the spring = 40 Nm⁻¹

A = amplitude of the simple harmonic motion = 4 cm = 0.04 m

m = mass of the block attached to spring = 0.20 kg

w = angular frequency of the simple harmonic motion

Angular frequency of the simple harmonic motion is given as w = \sqrt{\frac{k}{m} } \\w = \sqrt{\frac{40}{0.20} }\\w = 14.14 rads^{-1}

v = Speed of the block as it pass the equilibrium point

Speed of the block as it pass the equilibrium point is given as

v = A w\\v = (0.04) (14.14)\\v = 0.57 ms^{-1}

F F= {mango, apple, banana, orange)​
Stels [109]

Answer:

<h3>n(F) = 4</h3>

Explanation:

Cardinality of a set is the number of elements in that set. Given the set.

F= {mango, apple, banana, orange)​, we are to determine the cardinality of the set i.e the amount of fruit present in the set. Cardinality of the set F is represented as n(F).

Since there are 4 different fruit in the given set F, hence the cardinality of the set F is n(F) = 4
