The air helps the ships move faster and use less fuel to move <span />
The main difference between the drift current and diffusion current is the corresponding reaction of the semiconductor materials in the electric fields. In electric fields, when semiconductor material's movement go along with the direction of the electric field it is called drift current, but when it tends to go from high concentrated area to lower concentrated area then it is diffusion current.
Answer:
Explanation:
The system is made up of three body system which are the boulder, earth and the moon also the sum of potential ad kinetic energies are assumed to be the same also note that the boulder was launched from the moon at an initial velocity
A ) Minimum speed of the boulder for it to reach the earth = 2.3 km/s
B) ignoring air resistance the impact speed on earth of a boulder launched at this minimum speed = 11 km/s
find attached the solution in details
True, the measurement shown is a derived unit.
