The left and right sides of the diagram show a temperature-sensing device at two different temperatures. the device is made of two metal strips labeled a and b, and the device is connected into an electric circuit. which statement explains why the device works? metals a and b have different latent heats. metals a and b have different thermal expansion coefficients. metals a and b have different heat capacities. heat always flows across a temperature gradient.

For waves in the ocean, the medium of the waves is a. air b. water c. energy d. a passing boat

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
