A student must determine the effect of friction on the mechanical energy of a small block as it slides up a ramp. The block is launched with an initial speed vo from point A along a horizontal surface of negligible friction. It then slides up a ramp, where friction is not negligible, that is inclined at angle with respect to
the horizontal, as shown in the figure. The student measures the maximum vertical height h attained by the block while on the ramp, labeled as point in the
figure. At point B, the block comes to rest. The student performs three trials with the ramp at different angles, launching the block at the same initial speed vo
for each trial. The results from the trials are displayed in the table.
How should the student use the data collected and the known quantities from the experiment to determine the initial total mechanical energy of the block-ramp-
Earth system for all trials in the experiment?

what is the actual question though?

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.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
