Two balls A and B are thrown from the point with similar velocity of 19.6 m/s at
angle theta and 90-theta with horizontal
respectively Ball B reaches 10 m higher than
ball A. Find the individual
in maximum height reached by balls A and B.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

1 the 4 is sig

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
