Carl measures the temperature of the water at different depths of the lake to see if there is a relationship.
Oksi-84 [34.3K]
Independent variable - Water depth

The independent variable is something that is purposely changed in order to see the effects of change on the dependent variable. So since Carl wants to measure the temperature of water at different depths we will purposely change the depth of the water in order to observe how this would affect the temperature. 

Dependent variable - Temperature of the water 

The dependent variable is something that is dependent on the independent variable and is assumed to change as the independent variable changes. So we can determine that the temperature of the water is the independent variable as Carl expects it to change with the depth of the water. Another reason we can determine this is the dependent variable is because Carl can change the depth of the water measured but not the temperature of the water depths.

A SPARK PLUG IN AN AUTOMOBILE ENGINE CONSISTS OF TWO
kirill [66]

Answer:

Electric potential, V=3.52\times 10^{12}\ volts

Explanation:

It is given that,

The magnitude of electric field, E=4.7\times 10^7\ V/m

Distance between automobile engines that consists of metal conductors, d = 0.75\ mm = 7.5\times 10^4\ m

Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:

V=E\times d

V=4.7\times 10^7\ V/m \times 7.5\times 10^4\ m

V=3.52\times 10^{12}\ volts

So, the magnitude of the potential difference between the conductors is 3.52\times 10^{12}\ volts. Hence, this is the required solution.

Paladinen [302]

Weight of the mass is the tension in the string if the turntable is held fixed, with the mass hanging from the pulley

Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth. Weight (symbolized w ) is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface.

The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.

The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.

Tension will act opposite the the weight of the mass attached in order to maintain equilibrium .
