I believe the correct answer is atmosphere (D).
Answer:
B.useful products
Explanation:
industry is a sector that produces goods or services within an economy
Answer: d) 20J
Explanation:
Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is <u>a scalar magnitude</u>, and its unit in the International System of Units is the Joule (like energy). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
Now, <u>when the applied force is constant and the direction of the force and the direction of the movement are parallel</u>, the equation to calculate it is:
(1)
When they are not parallel, both directions form an angle, let's call it . In that case the expression to calculate the Work is:
(2)
In this case both (the force and the distance in the path) are parallel, so the work performed is the product of the force by the distance traveled . as shown in equation (1).
Hence:
>>>>This is the work
An increase in the level of nitrogen dioxide and a decrease in the level of ground-level ozone occurs.
Explanation:
Ozone gas is normally found in stratosphere, it protects us from solar radiation. Under certain circumstances, it can be formed on the ground level.
Conditions that have to be met in order for this to happen are existing of nitrogen oxides and volatile organic compounds and their reaction catalyzed by heat and light.
During dark, cold and cloudy days, due to the lack of heat and light from the Sun, formation of ozone will be decreased.
Also, this will enable building up of nitrogen dioxide, due to the same reason, leading to increased concentration.
