It is Yellow, Cyan, Magenta . The answer is D.
Answer:
fr = 514.5 N, This force has the opposite direction to the applied force.
Explanation:
Let's propose the solution of the problem using Newton's Second Law, we place a reference frame with the horizontal x-axis
Y axis
N- W = 0
N = W
X axis
F -fr = m a
the friction force has the expression
fr = μ N
fr = μ mg
fr = 0.35 150 9.8
fr = 514.5 N
This force has the opposite direction to the applied force.
The student's answer is incorrect because the friction coefficient must be multiplied by the normal

The most effective forces on the object are the backward force of air resistance relatively very small in magnitude, and the force of gravity. Because the spiral path of the satellite is not perpendicular to the gravitational force, one element of the gravitational force pulls forward. at the satellite to do fantastic work & make its speed increase.
<h3>What is called gravitational force?</h3>
Gravity, additionally referred to as gravitation, is a force that exists amongst all material gadgets withinside the universe. For any objects or particles having nonzero mass, the force of gravity tends to draw them in the direction of each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.

<span>436 km
The conversion factor between kilocalorie/hour and watts is 1.163 (1 kcal/hr = 1.163 watt). So let's convert the energy consumption of the bird from watts to kcal/hr
3.7 w / 1.163 w hr/kcal = 3.18 kcal /hr
1 gram of fat has 9 kcal, so the total number of kcals consumed will be 4 * 9 = 36.
So the bird can fly for 36/3.18 = 11.32 hours
The distance traveled will be
11.32 h * 3600 s/h * 10.7 m/s / 1000 m/km = 436 km</span>
