A microscope is used for the purpose of magnification of an object which is usually very minute - so much so that it is not easy to be seen with the naked eye. If a mount slide contains the word <em>lens</em> which is easily readable with the naked eye and if this slide is kept under a microscope, the text will appear:
- From left to right that is in the same original direction as it was positioned on the slide.
- Highly magnified which may make it illegible to be read using the microscope.
Answer:
A. 400 J
Explanation:
Because the process is isochoric, no volume change, so no work, so none of the energy is lost or converted. In other words, the system will gain and hold onto all of the J of heat put into it, which was 400J
hydrogen
Explanation:
Selenium is an element whose trace amounts are essential for life, as proven in 1979 based on its cumulative function with vitamin E [23]. Increasing deficiency of selenium in different parts of the world leads to the occurrence of many pathological disorders
Answer:
Irradiance (sunlight intensity or power), in Watts per square meter falling on a flat surface. ... Air Mass refers to “thickness” and clarity of the air through which the sunlight passes to reach the modules (sun angle affects this value). ... Cell temperature , which will differ from ambient air temperature
Answer:
The acceleration of the ball's center of mass = 2.94 m/s²
Explanation:
The speed of the ball at the base of the ramp, v = 2.63 m/s
Mass of the ball = 1.75 kg
Radius of the ball, R = 40 cm = 0.4 m
In this motion, potential energy due to the height of the ball is converted to linear angular kinetic energy
Based on the law of energy conservation
Potential energy = Linear KE + angular KE
KE = kinetic Energy
Linear KE = 0.5 mv²
Linear KE = 0.5 * 1.75 * 2.63²
Linear KE = 6.052 J
Angular KE = 0.5 Iω²
I = 2/ 3 MR² = 0.667 * 1.75 * 0.4²
I = 0.187 N.s
ω = V/R = 2.63/0.4
ω = 6.575 Rad/s
Angular KE = 0.5 * 0.187 * 6.575²
Angular KE = 4.04 J
PE = mgh = 1.75 * 9.8 * h = 17.15h
Using the law of energy conservation
17.15h = 6.052 + 4.04
h = 10.092/17.15
h = 0.589 m
Using the equation of motion
