"Normal" atmospheric pressure is 101.325 kilopascals
= 101,325 pascals
= 101,325 newtons/meter² .
1 km² = (1,000 m) x (1,000 m) = 1 million m²
Force = (101,325 N/m²) x (1 million m²)
= 101,325,000,000 Newtons
= 1.013 x 10¹¹ Newtons
= 101.3 Giganewtons .
That's the weight of all the air sitting on 1 km² of land.
<span>F = kX</span>, where k is a constant factor characteristic of the spring: its stiffness, and X is small compared to the total possible deformation of the spring.
Answer:
Explanation:
a )
Work done by force = change in kinetic energy
F x s = ( vf² - vi² ) / 2m
F = ( vf² - vi² ) / 2ms
acceleration = ( vf² - vi² ) / 2m²s
b )
F = ( vf² - vi² ) / 2ms [ calculated above ]
c )
Work done by force
= change in kinetic energy
= ( vf² - vi² ) / 2m
Answer:
If one bulb goes out, other bulbs stays lit.
If there is break in one branch of the circuit, current can still flow through other branches.
Parallel circuits are simple to design and build.
Explanation:
In parallel circuits all the components and resistors are connected to common terminal or common supply.
So here if we disconnect one of the branch of the circuit then it will not affect the other branches of the circuit so it will not affect the current of other branches.
So here it is very easy to build a parallel circuit and if one of the branch of the circuit goes out then it will not affect the other branches.
I would say all of them, because when making an observation you use, sight,sound,taste,touch, and smell
