Answer:
A derived unit is a SI unit of measurement comprised of a combination of the seven base units. Like SI unit of force is the derived unit, newton or N where N=s21×m×kg. There are some commonly used derived units which includes: 1. Pressure = AreaForce=m2N.
Explanation:
Answer:
Explanation:
Assuming motion of equation of SHM as
where,
t=time
thus velocity at any Point x is given by
when speed is 50 % of its maximum value
(b)When Potential Energy is 50 % of total energy
Total Energy
potential energy at any x is given by
Remember that density is mass divided by volume. first u must calculate the volume. so do 100 to the power of 3(cause volume is width ×lenth×height so u end up having to do 100 ×100×100) in your calculator. U know the mass is 4.5 kilograms. simply do 4.5 divided by 100 to the power of 3.
The mass will accelerate. Balanced Forces: When forces are in balance, acceleration is zero<span>. </span>
