Energy and Work have the same unit of measurement which is Joules in SI units.
Explanation:
- A Joule of Work is said to be done on an object when energy is transferred to that particular object.
- If two objects are involved, when one object transfers energy onto the second, a joule of work is said to be done by the first object.
- Work is also the application of force on an object over a distance. So Work = Force × Displacement
- Energy is neither created nor destroyed. It is in 2 forms - kinetic and potential.
- Kinetic energy is defined as the energy of a moving object while potential energy is known as the energy that is stored within an object.
- Kinetic Energy = 1/2 × mass × (velocity)²
- Potential Energy = mass × acceleration due to gravity × height
- Both energy and work are measured in Joules.
<u>Answer</u>
Handle slides at the end.
Never view without a cover slip.
<u>Explanation</u>
A microscope slide is a thing glass made from common glass such as soda lime glass. They are used for holding objects for examination under a microscope.
There are two things that one should remember when using the microscope slide.
These things are ;
1. Handle slides at the end and
2. Never view without a cover slip.
Answer: the question is not complete. The forces acting on the object are not given.
Explanation:
Summation of the vector forces acting on the object will give the solution.
<span>Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation.
E = hv
where h is the Planck's constant (6.626 x 10-34 J s), v is the
frequency which is related to the wavelength by:
λv = c where λ is the wavelength and c is the speed of light (3.00 x
108 m/s)
Therefore, the energy equation
E = hc / λ
E = </span>6.626 x 10^-34 J s (3.00x10^8 m/s) / 670 x10^-9 m
E = 2.966865672x10^-19 J per photon
Total energy = 2.966865672x10^-19 J / photon ( 3.0 mol) ( 6.022x10^23 photon / 1 mol ) = 535993.95 J
