Answer:
2 cubic meters
Explanation:
Suppose ideal gas, when the temperature stays constant, then the product of pressure and volume is the same as before
where are the pressure and volume of the gas before. are the pressure and volume of the gas after. We can solve for the volume after
Answer:
1. 31,536,000 seconds
2. Car B traveled a longer distance
3. Volume of box = 0.235887 cubic meters
Explanation:
Q1. Age in seconds
1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
Therefore 1 year = 365 x 24 x 60 x 60 = 31,536,000 seconds
In scientific notation this would be
Q2. Comparing km and miles
Given:
1 km = 1000m and 1 m = 3.3ft, I km = 1000 x 3.3 = 3300 ft.
Convert Car A distance of 25.7km to feet :
25.7 km. = 25. 7 x 3300 ft. = 84,810 ft.
For Car B that traveled 20 miles,
20 miles = 20 x 5280 = 105,600 ft.
Since 105,600 > 84,810, car B traveled a longer distance
Q3. Volume of wooden box
The wooden box is in the shape of a rectangular prism
It volume is L x W x H
Volume = 1.525 x 0.30 x 0.5156 = 0.235887 cubic meters
AM and FM are the two types of modulation that an omnidirectional antenna transmit.
<h3>What is an
omnidirectional antenna?</h3>
An omnidirectional antenna is also referred to as an isotropic antenna and it can be defined as a type of antenna that is designed and developed to radiate equal radio power or intercept radio-frequency (RF), especially in all directions perpendicular to an axis.
In Science, there are two types of modulation that an omnidirectional antenna transmit and this include the following:
- Frequency modulation (FM).
- Amplitude modulation (AM).
