Answer:
This example of the effect of volume on the pressure of a given amount of a confined gas is true in general. Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure.

Answer: 1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then
2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

Answer:
F = 64.0 N
the magnitude of the force is 64 N
Explanation:
Given;
Mass m = 45kg
time t = 7.5 s
Displacement d = 40 m
Force = mass × acceleration
F = ma ........1
From equation of motion;
d = vt + 0.5at^2
Since initial velocity v = 0 (initially at rest)
d = 0.5at^2
Making a the subject of formula;
a = d/(0.5t^2)
Substituting the given values;
a = 40/(0.5×7.5^2)
a = 1.42 m/s^2
From equation 1;
F = ma
Substituting the given values;
Force F = 45 kg × 1.42 m/s^2
F = 64.0 N
the magnitude of the force is 64 N
<h3><u>Answer;</u></h3>
<em>Producers </em>
<h3><u>Explanation;</u></h3>
- <u><em>Producers </em></u>occupy the lowest level in any food chain or food web. They are the organisms that all other organisms in the food chain rely on.
- <em><u>Producers </u></em>have the ability to make their own food through the process of photosynthesis where they use energy from sunlight, together with water and carbon dioxide to generate food.
- The ability of producers to make their own food and the fact that they occupy the lowest level in a food chain means <em><u>they have the highest biomass.</u></em>
Measured in joules - Thermal energy
Measured with a thermometer - Temperature
Does not depend on how much material there is - Thermal energy
Measured in degrees Celsius - Temperature
Increases if you heat something for longer - Thermal energy
