Answer:
Resistance of the light bulb = 1.33 ohm (Approx.)
Explanation:
Given:
Current in electric bulb = 2 Amp
Voltage in battery = 1.5 Volt
Find:
Resistance of the light bulb
Computation:
Resistance = Voltage / Current
Resistance of the light bulb = Voltage in battery / Current in electric bulb
Resistance of the light bulb = 2 / 1.5
Resistance of the light bulb = 1.33 ohm (Approx.)
Answer:
V₂=153.84 m L
Explanation:
Given that
Initial volume ,V₁ = 200 m L
Initial pressure ,P₁= 500 torr
Final pressure P₂ = 650 torr
Lets take the final volume =V₂
Given that process occurs at constant temperature and we know that for constant temperature process
P₁ V₁ = P₂ V₂
Now by putting the values
V₂=153.84 m L
Therefore the new volume of the gas will be 153.8 4mL.
When conducting a search to identify a text's credibility and reliability, you have to check the following characteristics:
- Sources: where the information is obtained and it is supposed to be true. It is said that you need at least three different sources that explain the same information for it to be validated.
- Is the article is current?: articles could change all the time, specially scientific ones because new discoveries can change what was discovered before, so it is important to check if the text you are reading is current or not, and if it is not, you need to check if something has changed during all those years.
<h3>Article's credibility</h3>
In this exercise, you have to present an article and describe the purpose of the source and if the article is current or not.
For example, let's select an article called "How using social media affects teenagers".
The purpose of the sources in this article is to demonstrate how social media affects teenagers using different surveys.

Answer:
Driver hits the dog
Explanation:
From kinematics equation
and making a the subject
F=ma=800*-4=-3200 N
The driver is required to apply a force of 3200 N to effectively not hit the dog. However, when the driver applies 2000 N, this is less the required force by 1200 N hence the driver hits the dog.
Answer:
Explanation:
Given:
- Initial temperature,
- initial volume,
- final temperature,
- volumetric coefficient of thermal expansion for gasoline,
- volumetric coefficient of thermal expansion for steel,
<u>Now the increment in the volume of the container:</u>
<u>and the increment in the volume of the gasoline:</u>
<u>Hence the difference in the increment of the two volumes:</u>
of the gasoline spills out of the container in this case.
