force × distance = work done
4200N × 1609m = 6,757,800Nm
Velocity of the plane relative to the air = +400.0 m/s
Velocity of the air relative to the ground = -35.0 m/s (negative because it's moving opposite to the eastward direction)
Velocity of the plane relative to the ground = (velocity of the plane relative to the air) + (velocity of the air relative to the ground) = 365.0 m/s to the east
I believe the answer is 40,000 Hz to 100,000 Hz
Explanation:
physical quantity is any physical property that can be qualified that,is, be measured using numbers e.g mass, amount of substance,time and length
Parfocal is the term used to describe a microscope that maintains focus when the objective lenses are replaced.
<h3>
What is the name of the objective lens ?</h3>
For observing minute features within a specimen sample, a high-powered objective lens, often known as a "high dry" lens, is perfect. You can see a very detailed image of the specimen on your slide thanks to the 400x total magnification that a high-power objective lens and a 10x eyepiece provide.
The four objective lenses on your microscope are for scanning (4x), low (10x), high (40x), and oil immersion (100x).
The first-stage lens used to create a picture from electrons leaving the specimen is referred to as the "objective lens." The objective lens is the most crucial component of the imaging system since the quality of the images is determined by how well it performs (resolution, contrast, etc.,).
