Answer:
Elements of weather
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
Air pressure, humidity, clouds and temperature are all called elements of weather. The other elements of weather are;
- Wind
- Precipitation.
Air pressure, humidity, clouds, and temperature are all part of weather and climate studies. They represent the weight of air above a point on the earth's surface, the amount of water vapor in the atmosphere, collections of airborne water droplets or ice crystals, and the heat energy in the atmosphere, respectively.
Air pressure, humidity, clouds, and temperature are all components of weather and climate studies, key elements of geography and meteorology. Air pressure is the force exerted by the weight of air above any given point on Earth's surface. Humidity refers to the amount of water vapor in the atmosphere. Clouds are collections of water droplets or ice crystals that form in the Earth's atmosphere when water vapor condenses. Temperature is a measure of the amount of heat energy in the atmosphere, usually expressed in degrees Celsius or Fahrenheit. The combination of all these factors form different weather patterns and influence the Earth's overall climate.

B) None of the remaining light bulbs will be on.
C) Only the bulb closest to the switch will be on.
D) All three remaining light bulbs will be brighter than before.
The correct answer is option B) None of the remaining light bulbs will be on.
In a series connection when a bulb is removed, it will be creating a open circuit. Since the circuit is series and is open at a point current will not flow and hence the other bulb will not glow.
That's because the basic requirement for the circuit to operate a continuous, closed-loop path is no longer met. This is the main disadvantage of a series circuit. If any one of the light bulbs or loads burns out or is removed, the entire circuit stops operating.

b. periodic condensations and rarefactions.
c. high- and low-pressure regions.
d. all of the above E. none of the above
Sound waves in air are a series of periodic condensations and rarefactions.
Sound waves in air are a series of periodic condensations and rarefactions. When a sound is produced, it creates compression regions (areas of high pressure) and rarefaction regions (areas of low pressure) that propagate through the air. These alternating regions of high and low pressure create the characteristic waveform of the sound wave.

Answer:
A) The acceleration will double
Explanation:
Given the expression according to Newton's second law F = ma where;
F is the force
m is the mass of the object
a is the acceleration
Let the initial force be F1 and acceleration be a1
F1 = ma1...(1)
If the pushing force suddenly doubles if the lawn mover is pushed over a length of grass, the new force F2 = 2F1 and acceleration of force F2 will be a2, since the mass doesn't change;
F2 = ma2
2F1 = ma2...(2)
Dividing equation 2 by 1, we will have;
2F1/F1 = ma2/ma1
2 = a2/a1
a2 = 2a1
This shows that the acceleration doubles if the pushing force doubles since force is directly proportional to the acceleration. Increase in the applied force will lead to equal increase in the acceleration and vice versa
