Answer:
As you know, g = 9.81 m/s on the surface of the Earth. ... If the action force is the force she exerts downward on the chair, what is the reaction force? ... it take a 10-N force to increase the speed of a 10-kg toy car from 1.00 m/s to 4.00 m/s? ... (DH 32) How many joules of kinetic energy does a .5 kg cart have when it is ...
Step-by-step explanation:
Look at the picture hopefully it helps at least a little.
Keywords
complementary angles, right angle
we know that
If two angles are <u>complementary angles</u>, then their sum is equal to a <u>right angle</u>
In this problem
-------> by <u>complementary angles</u>
we have

Substitute and solve for Angle TSU

therefore
the answer is the option

The sum of all three is 6x^2y + 2xy^2
<span>The answer is She should have multiplied by 2 instead of dividing by 2.
First one.</span>
