To solve your problem, we can apply Newton's second law of motion.
Fⁿ = ma
<span>Fnet = net force acting on the skier </span>
<span>m = mass of the skier = 53 kg </span>
<span>a = acceleration up the slope </span>
<span>Since velocity is constant then acceleration is zero, hence the above equation becomes </span>
<span>Fnet = 0 </span>
<span>Fnet = F - Wx - f </span>
<span>where </span>
<span>F = force exerted by the tow bar </span>
<span>Wx = component of skier's weight parallel to the incline = 53(9.8)(sin 20) </span>
<span>f = frictional force = 0.160(53)(9.8)(cos 20) </span>
<span>Substituting appropriate values, </span>
<span>F - 53(9.8)(sin 20) - 0.160(53)(9.8)(cos 20) = 0 </span>
<span>and solving for F, </span>
<span>F = 99.55 N </span>
<span>Hope this helps and have a nice day!</span>
Answer: Nowadays, it's very common for some people to have life insurances or auto insurances. Life insurances are given to a household when a primary wage earner dies, in order for the family to <u>have a financial help to deal with the absence of this primary wage</u>. It basically helps the household on <u>affording ordinary bills and mortgage expenses </u>for a certain period of time that might be hard for them. Auto insurances can protect you against accidents that might happen and cost you repairs or even a replacement. The insurance could also <u>cover medical expenses of the victims</u>, depending on what kind of agreement is made. Also, there's insurance against theft or natural disasters, that also help the owner financially to replace the car.
These types of insurance are important in order for you to plan your expenses better and to be prepared for unfortunate events that are unpredictable. Also, they can offer enough support for a family not to struggle to keep the household expenses if these events happen.

Explanation:
The active voice is a morphological grammar voice, that is, an inflectional form of verbs that marks the subject's role in the sentence. Therefore, the active voice indicates that the subject is the one who makes the action in the sentence (that is, is active), in contrast to, for example, the passive voice, where the subject constitutes the object of the action.
