Question 24.
The Environmental Protection Agency is a regulatory agency that protects human and environmental life. Because it is a regulatory agency, it oversees all actions that has a direct effect on the environment. Letter A could be an answer, but not the best. The EPA does not trust environmentalists because they still have to inspect the ship. Maybe the ship would drive away fishes from their aquatic homes which would cause an imbalance in the ecosystem. So, the best answer would be letter C.

Question 25:
Gravity is a force of attraction that acts as the pull towards the object's center. According to Newton's Law of Universal Gravitation, the force of gravity is directly proportional to the mass, and inversely proportional to distance. The heavier and nearer the objects are, the greater the force of gravity. Every object in the world is acted upon by gravity, whether at rest or moving. Therefore, the answer is B.

Question 26:
Power is the amount of work done per unit time. So, if time is not changed and work increases, the power will have to increase as well. The answer is C.

Question 27:
In electricity, the power of the load in a circuit is equal to the product of its voltage and current. Therefore, voltage and current are directly proportional to power. But they are inversely proportional to each other. So, if voltage increases, the power also increases. Therefore, the answer is B.

Question 28:
Hybrid cars work on the energy both coming from oil and electricity. Electricity is a more expensive fuel than oil. So, you will expect that hybrid cars are much more expensive. Electricity comes from batteries, which is made up of electrolyte solutions of metals. They are non-renewable source as well. The only advantage is that, batteries do not emit pollutant gases unlike oil. These gases deteriorate the ozone layer which protects the Earth from exposure to UV rays. Therefore, the answer is B.

1.Components in a series circuit share the same current.

2.The sum of individual voltage drop in a series circuit equals that supply voltage.

Explanation:

In a simple circuit, the amount of current is the same flowing through the resistor and the battery as long as it is a series circuit.Components in a series circuit share the same current.

In a series circuit, the total resistance equals the sum of individual resistance

The sum of individual voltage drop in a series circuit equals that supply voltage.

In part h, you discovered that the luminosity of a light bulb increases if the current increases. the rate at which electric potential energy is converted into heat depends on the current flowing through the bulb and the voltage across the bulb. this energy is supplied by the battery. mathematically, the luminosity p of the light bulb is given by p=δvi, where δv is the voltage across the bulb and i is the current.what happens to the luminosity of the light bulb if the voltage of the battery is doubled? (note that the phet simulation does not display

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

Question 15 (3 points) (9.40_q15) the 9 volt battery is replaced with a 12 volt battery in a circuit with 12 ω resistance. what happens to the current? the current increases. the current is unchanged the current decreases. question 16 (3 points) (9.40_q16) what is the current in a circuit with a 6 volt battery and 1.5 ω resistance? 0.25 amp 0.4 amp 4 amp 9 amp question 17 (3 points) (9.40_q17) a 6 volt battery is replaced with a 3 volt battery in a circuit with 3 ω resistance. what happens to the current? the current increases. the current is unchanged

Step-by-step answer

P Answered by PhD

15. Current increases

16. 4 Amp

17. Current decreases

18. A direct relationship

19. voltage affects current

20. Current is unchanged

Explanation:

First you need to know about Ohm's Law. Ohm's law can be summarized in the formula:

$I = \dfrac{V}{R}$

where:

V = Voltage

I = Current

R = Resistance

As you can see, when you increase the voltage, the current increases as well. When you decrease the resistance, current increases as well. This means that voltage has a direct relationship with current, and current has an indirect relationship with resistance.

Voltage is the potential, or electrical potential energy that pushes the current along a circuit. THe current is the flow of energy, so it is actually the rate of electrical energy that goes through a point in a circuit over a period of time. The resistance is the resistive force, that the current goes through as it goes through a circuit.

Let's apply that to question 16:

$I=\dfrac{V}{R}$

Our given:

V = 6V

R = 1.5Ω

$I=\dfrac{6V}{1.5\Omega}=4A$

In question 17,just to show you, we can solve it and compare:

6 V battery and 3Ω resistance:

$I=\dfrac{6V}{3\Omega}=2A$

3 V battery and 3Ω resistance:

$I=\dfrac{3V}{3\Omega}=1A$

Current decreases from 2A to 1A.

Let's try it on Question 20:

12V and 5Ω

$I=\dfrac{12V}{5\Omega}=2.4A$

6V and 2.5Ω

$I=\dfrac{6V}{2.5\Omega}=2.4A$

There is no difference.
