<span>Let t be the angle made by T3 with the x-axis.
T3 * cos(t) = 20 N ---- (1)
T3 * sin(t) = 60 N ----- (2)
Square both equations and add:
T3^2 = 20^2 + 60^2 = 400 + 3600 = 4000
T3 = sqrt(4000) = 63.25 N
divide (2) by (1):
tan(t) = 60/20 = 3
t = arctan(3) = 71.57 degrees.
</span><span>Since the angle clockwise from the x-axis some books may call it a negative angle and say the angle is -71.57 degrees or round it to -71.6 or even -72 degrees.</span>
Answer:
electrostatic force
Explanation:
Electrostatic force is the force that exists between electric charges on stationary charged bodies
Our sun is quite average when looking at all the stars in the Universe. There are stars that are smaller, like Wolf359, and there are also larger stars, like Betelgeuse. Our sun is essentially right in the middle of the star-size spectrum.
Answer:
A & B
Explanation:
A & B Would be the right answer since Morse code cannot be represented through the height of the fire.
