Credit Card should be the answer.
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:
Waste heat from energy convertion plants has led to national warming.
Explanation:
Waste heat from the above plants are emitted directly into the environment, this heat does not become extinct, it becomes part of the environment causing a warming effect, and a negative change in the climate.
Further Explanation
Other than the above cause, global warming also contributes to the warming of the enviroment.
<span>The endocrine system helps to regulate the nervous system is NOT true</span>
