Ocean circulation is the large-scale movement of water in the ocean. It involves the transport of heat through convection, which is the movement of heat through liquids and gases. Which statement describes how convection moves heat in the ocean during non-El Niño (normal) years?

Convection moves heat toward the west.
Convection moves heat toward the east.
Convection moves heat toward the north.
Convection moves heat toward the south.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

What are known as the properties of substances that describe a substance et does not change that substances?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
