Answer:
Here Are Some Tanning Bed Tips For Beginners To Help You Get The Most .Knowing your skin type before you tan can help you to do so safely and help . If you want to ensure you get a quality tan, you first need to be certain your . Obviously, if you wear a bathing suit, you'll get tan lines from the suit. Apply indoor tanning lotion evenly in a circular motion and over all areas of the body. Using the right skin care products is the best way to extend the life of your tan. Note that lotions not made for indoor tanning can cause damage to tanning beds and don't help develop your tan. So what (if anything) should you wear? There are a lot of different views on this particular question, and it all comes down to one very simple answer: wear whatever you are comfortable in. If you wear your bathing suit every time, you will have tan lines that reflect that, but that's your choice.
Explanation:
Bigger change in velocity because the object is lighter than the object with more mass so it would move further (sorry it’s not a great explanation)
The motor does 20 J of work on the block, it means that the total mechanical energy of the block has increased by 20 J. But the increase in total mechanical energy is equal to the sum of the increases in potential energy and kinetic energy:
So, if the gravitational potential energy has increased by 15 J, the kinetic energy has increased by
Answer:
3.3 rad/sec.
Explanation:
The term '' average angular velocity'' can be defined as the rate at which the angular velocity changes. Kindly note that the rate in which the angular velocity changes is in radian per seconds[rad/sec]. So, without mincing words let's dive straight into the solution to the question above.
The radius of the blowing ball = 12cm, the initial angular velocity = 5.0 rad/s, the final angular velocity = 1.5 rad/s and the angle of rotation = 5.5 radians.
Therefore, from the definition of average angular velocity given above, the mathematical representation can be written as given below:
The average angular velocity = [ the initial angular velocity] + [the final angular velocity] / 2.
Thus, the average angular velocity = [ 5.0 rad/s + 1.5 rad/s] / 2 = 3.3 rad/s.
3. Nuclear power station or plants obtain heat required to heat water to produce steam from nuclear fission reactions (physical process) which entails the splitting of atoms of uranium in the nuclear reactor. The uranium fuel consists of small, hard ceramic pellets that are packaged in to long vertical tubes and are inserted into the reactor. The steam produced then turns turbines to produce electricity. Therefore the correct answer is C.
10. Nuclear fission reactions are physical processes that involves splitting of radioactive isotopes to form other stable atoms coupled with production of energy. Chemical reactions on the other hand are reactions involving rearrangements of atom structure to form other substances (products). Nuclear fission reactions are not affected by the environmental factors such as temperature while chemical reactions are affected by these changes, therefore increase in temperature affects chemical reactions but doesn't affect nuclear reactions. Therefore, the correct answer is A
