What kind of image is formed in the retina of the eye? An image is formed on the retina with light rays converging most at the cornea and upon entering and exiting the lens. Rays from the top and bottom of the object are traced and produce an inverted real image on the retina. The […]
What type of acid is sodium hydroxide?
What type of acid is sodium hydroxide? sodium compounds Sodium hydroxide (NaOH) is a corrosive white crystalline solid that readily absorbs moisture until it dissolves. Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. It is highly corrosive to animal and vegetable tissue. The alkaline solutions it forms… Is […]

Positron and electron both have mass of 0.00055 amu. What has the greatest mass? Neutron Which particle has greatest mass? The heaviest of […]
What is the similarities between magnetism and gravity?
What is the similarities between magnetism and gravity? Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. Why is gravitational force a non contact force? […]
How do you find displacement with time and distance?
How do you find displacement with time and distance? Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time. What is the formula to find displacement? Displacement (s) […]
Why are there two neap tides monthly?
Why are there two neap tides monthly? Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. During full or new moons—which occur when the Earth, sun, and moon are nearly in alignment—average tidal ranges are slightly larger. This occurs twice each month. How […]
What is temperature on a PV diagram?
What is temperature on a PV diagram? With everything tied together by the ideal gas law, one variable can always be described as dependent on the other two. Temperature is the slave of pressure and volume on a pressure-volume graph (PV graph). What is name of the curve obtained in PV diagram? Only two thermodynamic […]
Which unit is used to measure the speed of computer?
Which unit is used to measure the speed of computer? Clock speed is measured in units of cycles per second, which is called a Hertz (Hz). Computer boards and CPUs run at rates of millions and billions of Hertz, megahertz (MHz) and gigahertz (GHz). What unit is typically used to measure the speed of a […]
Which part of VOM has a negative and positive probe?
Which part of VOM has a negative and positive probe? Test Probe- Serves as the input portion of the ohmmeter. Red test probe becomes positive in some instances, while the black one is negative. Which type of meter is used to test the polarity of battery? Solenoid volt meters What is the color of the […]
What are the 3 aspects of sound?
What are the 3 aspects of sound? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. What is the […]
