Answer:
<u>Static</u><u> </u><u>friction</u><u> </u><u>:</u>
The frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object.
<u>Rolling</u><u> </u><u>friction</u><u> </u><u>:</u>
Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects.
C. Mostly the spongy and also the compact
Before getting married, someone wants to shed 13 pounds. To reach this objective, the person should schedule their meals to save 45,000 calories overall.
There is no one optimal strategy to lose weight, but all weight-loss programs create a calorie deficit, which means you'll either consume fewer calories than you did previously, increase your calorie expenditure through activity, or do a combination of the two.
Since adherence is the primary factor in determining whether a weight-loss strategy is successful, it is preferable to think of a plan that fits your needs rather than one that has a certain macronutrient breakdown (for example, high protein or low fat). For instance, a weight-loss program like Jenny Craig that stresses pre-packaged meals and largely restricts these activities won't be the greatest fit if you frequently travel or eat out.
