2. Two trucks are travelling down the road. Truck A covers a displacement of 3 miles in 1 minute. Truck B covers a displacement of 4.5 miles in 1 minute. Which of the following correctly explains
which truck is faster?*
(1 Point)
Truck A is faster because it covers less displacement in the same amount of time
Truck B is faster because it covers a greater displacement in the same time
Truck B is faster because its takes more time to cover a greater displacement

In a hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. how many unique charge-pairs are there (without double counting)?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

What do the atoms of elements in the same group have in common? a. they have the same atomic numbers. b. they have the same average atomic masses. c. they have the same number of electron shells. d. they have the same number of electrons in their outermost shells.
