It's the angle made by the incident ray when it's perpendicular to the surface. (Perpendicular lines are the lines that form a graph or like a 90-degree angle)
Answer:

may change little during their lives, but they do grow

Answer:
Explanation:
From the exercise we know that the force on the plane is 7934N upward at an angle of 54.2º.
If analyze the forces in the vertical direction, the acceleration is zero because the plane is moving with constant velocity
∑
So, the <u><em>weight of the plane</em></u> is 6435N
Answer:
Car C
Explanation:
It is given that,
Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :
Car A = 890 m/s
car B = 850 m/s
Car C = 790 m/s
Car D = 895 m/s
Car E = 870 m/s
The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.
Where
d = distance
t = time required by the car to come to a full stop
So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.
Answer:
<em>Vernal equinox, autumnal equinox, march equinox, September equinox, northward equinox and southward equinox </em><em>are the names for the equinoxes.
</em>
<u>Explanation:
</u>
There are different names which are named depending on the <em>month of the year when these equinox occurs and depends upon direction of motion of the sun</em>.<em> Equinox is a point where day time and night time have exactly equal length of time.</em>
Equinox occurs <em>twice</em> in a year and this occurs when <em>earth's equator passes through the sun</em>. We can say that equinox occurs when the sun’s center is directly above the equator.
