Because plastic and rubber are known as insulators which keep metal wires protected
The time to distance ratio is 2.1:1 , making the first time 5 seconds, the first distance 18.9 m, and the second time 15 seconds. I hope this helps!
Answer:
The two equations below express conservation of energy and conservation of mass for water flowing from a circular hole of radius 3 centimeters at the bottom of a cylindrical tank of radius 10 centimeters. In these equations, delta m is the mass that leaves the tank in time delta t, v is the velocity of the water flowing through the hole, and h is the height of the water in the tank at time t. g is the acceleration of gravity, which you should approximate as 1000 cm/s2.

Answer:
displacement at 45 s = 30
65 s = 50
So the average speed over the interval from 45 s to 65 s is
(50 - 30) cm / 20 s = 1 cm / sec
As a check an average speed of 1 cm / sec for 20 sec will produce a
displacement of 1 cm / sec * 20 sec = 20 cm or from 30 to 50 cm
Hydraulic pressure is actually the pressure that is exerted to liquid and the pressure gets transmitted throughout the liquid. Since liquid cannot be compressed, so the pressure that was exerted on the liquid gets transmitted to the walls of the container containing the liquid. This theory is applied to the braking system of cars and some other vehicles. This is known as the hydraulic pressure. It is actually the science that is concerned with the laws of movements of a fluid and the application of this theory for engineering purpose. This theory has not only been used in cars but also in planes .
