Suppose f (t) = −11t2 is the position at time t of an object moving along the x axis. use the limit definition to find the velocity of the object at time t0 = −5.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

What is a possible result of higher air temperature caused by global warming

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
