Four masses are suspended on weithless strings as shown below The tension T1 in the top string is
2 points
T1 = m1+m2+m3+m4
T1 =( m1+m2+m3+m4)g
T1 = m1*g
none of the above
Other:

The tension in the second from top string is *
2 points
T2 =( m1+m2+m3+m4)g
T2 =( m2+m3+m4)g
T2 =( m1+m2)g
T1 =( m1)g

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque
