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>
5=true
6=c
7=D
I think these are correct but 7 might be A so yeah
Answer:
Dutch missionary John Megapolensis on the Mohawks (Iroquois), 1644
HIPP+:
Historical Context:
This represents the situation that Dutch missionary John Megapolensis found when converting the Mohawks (Iroquois) Indians to Christianity in the year 1644. The story narrated that John was the first pastor at Fort Orange (near Albany).
Intended Audience:
This represents the readers of the story, especially students of history who will be reading the story of Pastor John about his personal experiences in Fort Orange as he tried to convert Indians to Christianity.
Author's Purpose:
The purpose of the story is to narrate John's experiences so that his intended readers will be able to appreciate the difficulties that he faced in his missionary efforts with the Indians.
Author's Point of View
: John tells this story from the first person point of view because the story contains his personal experiences as a missionary to the Indians and he narrated the story from his personal position as an observer-participant, using the personal pronoun, 'I'.
+Other Context (similar in kind, from a different time): The story included pieces of information about the division of labor between the Indian women and their men. It also included information about the treatment of enemies and the Indian worship of the Devil instead of God.
Explanation:
The HIPP is an acronym for a) Historical Context, b) Intended Audience, c) Narrator's Purpose, and d) the Author's Point of View. This is the standard system for analyzing historical events in order to achieve a better understanding of the historical story.
Answer:
Explanation:
1. Calculate the perimeter p
p = a + b + c = 174 + 138 + 188 = 500
2. Calculate the semiperimeter s
s = p/2 = 500/2 = 250
3. Calculate the area
We can use Heron's Formula:
![\text{The area of the triangle is } \boxed{\textbf{11486}}]](https://tex.z-dn.net/?f=%5Ctext%7BThe%20area%20of%20the%20triangle%20is%20%7D%20%5Cboxed%7B%5Ctextbf%7B11486%7D%7D%5D)
