2a for example the first one,2sec. You know that every second it moves 3metres further. So 2x3=6 but you start at 0.50m so 6+0.50=6.5
The seafloor is only expanding in one area, which is the Atlantic Ocean. It's just Earth's seafloor recylcing itself.
The thin atmosphere of Mars is thought to be due to the planet's lack of a magnetic field, which has allowed the Solar wind to blow away much of the gas the planet once had. Venus, despite still having a thick atmosphere of CO2, surprisingly has a similar problem
Answer:

Explanation:
Given that
V= 12 V
K=3
d= 2 mm
Area=5.00 $ 10#3 m2
Assume that
$ = Multiple sign
# = Negative sign

We Capacitance given as
For air







Net capacitance
C=C₁+C₂

We know that charge Q given as
Q= C V


Answer:
The hydraulic press allows the applied force (F1) to be converted into a higher force (F2) along some path as many times as the surface of the driven hydraulic cylinder (A2) is larger than the surface of the driving hydraulic cylinder (A1). The hydraulic press works on the basis of Pascal's law, which reads: External pressure is transmitted through the fluids equally in all directions.
