A parallel circuit contains a battery with a voltage of 9 V. The total resistance in the circuit is 18 ohms. Which claim about the current in the circuit can be supported mathematically from the relationships between voltage, current, and resistance? A.
the current flowing through the circuit is 0.5 amps because current is related to voltage and resistance by the formula I = V/R
B.
the current flowing through the circuit is 162 amps because current is related to voltage and resistance by the formula I = VR
C.
the current flowing through the circuit is 27 amps because current is related to voltage and resistance by the formula I = R + V
D.
: the current flowing through the circuit is 2 amps because current is related to voltage and resistance by the formula I = R/V
Answer:
Its C I fell confident
Explanation:
I took 2 hrs I tried on this for u dont get mad have a wonderful day :D
So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V
What is resistance?Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.
E = I x R
So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V

A cube of wood exerts a pressure of 2 pa. When it is placed on a floor. What is the force by the cube if its surface is 5 cm²
Pressure exerted by the wooden cube = 2 Pa
Surface area of cube = 5 cm² = 0.0005 m²
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Formula of Pressure:
[tex] \boxed{ \bf{P = \dfrac{F}{A}}}[/tex]
P → Pressure
F → Force
A → Surface Area
By substituting values in the formula, we get:
[tex] \rm \longrightarrow 2 = \dfrac{F}{0.0005} \\ \\ \rm \longrightarrow F = 2 \times 0.0005 \\ \\ \rm \longrightarrow F = 0.001 \: N \\ \\ \rm \longrightarrow F = 1 \: mN[/tex]
[tex] \therefore [/tex] Force applied by the cube on the floor = 1 mN

Answer:
Engraving of the city of Kota from the east by Edward Francis Finden (1791-1857) and Patrick Young Waugh (1788-1829). Plate 2 of the 'Annals and antiquities of Rajast'han or the Central and Western Rajpoot States of India' published in London in 1832.
The Rajput city of Kota in southern Rajasthan was founded in the 14th century within the borders of the state of Bundi; it became the capital of an independent princely state of the same name in the early 17th Century. During the reign of the Mughal Emperor Jahangir, Rao Ratan Singh, the ruler of Bundi, gave the small principality of Kota to his son, Madho Singh. The Kota fort he gained possession of was built in c. 1264 by Rajkumar Jait Singh of Bundi and contains the city palace. It is situated on the bank of the River Chambal where it meets its tributary, the Shahi Dehra. This engraving shows a view of the Chambal with the ramparts and bastions of the fort rising from the rivers edge behind.

1. A ball rolls off of a table with a speed of 3.2 m/s. The table is 1.6 m high.
a) When does the ball hit the ground? (time)
b) How far away from the base of the table does the ball travel?
c) With what vertical speed does the ball hit the floor?
Answer:
Explanation:
for vertical displacement h = 1.6 , let time taken be t , initial vertical velocity = 0
h = ut + 1/2 g t²
= 1/2 g t²
1.6 = .5 x 9.8 x t²
t² = .3265
t = .57 s
b )
velocity in horizontal direction = 3.2 m /s
horizontal displacement
= 3.2 x .57 = 1.82 m
c )
for vertical movement
v = u + gt
= 0 + 9.8 x .57
= 5.58 m /s

How many times more gravitational potential energy would the same lander have on top of a 350-m hill on Earth? It would have times more gravitational potential energy
Answer:
6
Explanation:
Just did it.
The gravitational potential energy would the same lander have on top of a 350-m hill on Earth is 6.
What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
The heavier the particle and the higher it is over the ground, the more gravitational potential energy it holds. Gravitational potential energy increments as weight and level increments.
Given is the height of hill h = 350m.
Thus, the same lander will have the the potential energy 6 times more.

If it takes a planet 2.8 × 108 s to orbit a star with a mass of 6.2 × 1030 kg, what is the average distance between the planet and the star?
Answer:
9.36*10^11 m
Explanation
Orbital velocity v=√{(G*M)/R},
G = gravitational constant =6.67*10^-11 m³ kg⁻¹ s⁻²,
M = mass of the star
R =distance from the planet to the star.
v=ωR, with ω as the angular velocity and R the radius
ωR=√{(G*M)/R},
ω=2π/T,
T = orbital period of the planet
To get R we write the formula by making R the subject of the equation
(2π/T)*R=√{(G*M)/R}
{(2π/T)*R}²=[√{(G*M)/R}]²,
(4π²/T²)*R²=(G*M)/R,
(4π²/T²)*R³=G*M,
R³=(G*M*T²)/4π²,
R=∛{(G*M*T²)/4π²},
Substitute values
R=9.36*10^11 m
