Yes.
-- 'Acceleration' does NOT mean 'speeding up'.
It means ANY change in the speed OR direction of motion ...
speeding up, slowing down, or turning.
-- If an object is NOT moving in straight line at constant speed,
then its motion is accelerated.
-- In circular motion, or even just going around a curve,
the object is accelerating, because its direction is constantly
changing, even if its speed is constant.
Growing grass plants and trees is the easiest and best way to prevent flood waters from running off too quickly causing further soil erosion. <span />
'D' would do the job ... When you subtract the protons from the mass,
what you have left is neutrons. (The electrons can be ignored. It takes
around 1840 electrons ! to add the mass of a single proton or neutron !)
I don't know it for a fact, but I'd be surprised if the process is really that
simple. I mean, it starts out with knowing the atomic mass, and then
knowing the number of protons in the nucleus. Each of those is a
whole complex problem in itself.
Answer:
1300.80988 Nm
730.79206 kgm²
Explanation:
m = Mass of ladder = 23.8 kg
g = Acceleration due to gravity = 9.81 m/s²
L = Length of ladder = 9.08 m
F = Applied force = 260 N
= Angular acceleration = 1.78 rad/s²
I = Moment of inertia
Weight is given by
The center of gravity of the ladder lies at the center of the ladder
Torque will be
The net torque acting on the ladder is 1300.80988 Nm
Torque is also given by
The moment of inertia of the ladder is 730.79206 kgm²
Answer:
Explanation:
The detailed analysis and step by step calculation is as shown in the attached file.
b) The second question says what would be the work output if the turbine was assumed adiabatic.
