If timmy is traveling 20 miles per hour south for 2 hours. how far is he displaced

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
