Answer:
The answer is below
Explanation:
Pascal's law states that pressure is exerted in all parts of a static fluid equally.
The area of the narrower arm with a radius of 0.05 m (5 cm) is given as:
Area of narrow arm = π(0.05)²
The area of the wider arm with a radius of 0.18 m (18 cm) is given as:
Area of narrow arm = π(0.18)²
The ratio if the wider arm area to the narrow arm area = π(0.18)² / π(0.05)² = 12.96
To move the 12000 N car, the amount of force needed = 12000/12.96 = 926 N
Given : A car starts from rest and retains the acceleration of 4m/s² in 20 second. Calculate its final velocity.
Solution : As we know that a car starts from rest so it's initial velocity should be 0 m/s. Acceleration is 4 m/s² and time taken is 20 sec. So, we need to calculate it's final velocity which we can get it usi g the first equation of motion.
First Equation of Motion : v = u + at
Putting all the required values in the formula we will get v
<u>Henceforth, final velocity is 80 m/sec.</u>
True, because people should reach their full potential within themselves and human psychologist should help those that need help to reach it.
this can be a lot of things, depending on how much gravity they produce. if there is a lot of gravity they <em>could</em> create a galaxy, star, or planet. if there is still lots of gravity, but not as much they <em>could </em>create a comet, asteroid, or dwarf planet. it all depends. Bu it can also be to do with what you mean by basic structures, and what the objects are.
rock can create asteroids, planets and parts of galaxies, gas, dust, ice and other things may create the rest and contribute to the other things.
It can be calculated solely by knowing the vertical component of the velocity of projection.
The amount of time a projectile stays in the air only depends on its movement in the vertical direction, which is dependent on the vertical component of its velocity.
