The initial velocity of the car is 11 m/s.
Explanation:
- Here, we can use the equations of motions.
- The first of equation of motion is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
- The given parameters are,
Final velocity, v = 20 m/s
acceleration of the care, a = 2 m/
time, t = 3 s
Initial velocity, u = ?
- Hence, the equation can be written as u = v - at
once you substitute all these vales, you will get u = 11 m/s
Answer:
the answer is c) 25.1 feet/second
Explanation:
because the blood droplets can not increase speed past terminal velocity 100.
Answer:
Two identical closely spaced circular disks form a parallel-plate capacitor. Transferring 2.1×109 electrons from one disk to the other causes the electric field strength between them to be 1.6×105 N/C. What are the diameters of the disks?
Explanation:
Check attachment for solution
The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated
A direct current
this is a current that only flows in one direction
