What is a pulley system in physics? Pulleys are mechanisms compost by wheel and rope used to lift heavy objects onto tall heights. They change the direction of an applied force and they can even reduce the force needed to lift a weight. Pulleys systems are common used in constructions. What is the tension formula? […]
What are the different type of measurement?
What are the different type of measurement? The four scales of measurement Nominal scale of measurement. The nominal scale of measurement defines the identity property of data. Ordinal scale of measurement. The ordinal scale defines data that is placed in a specific order. Interval scale of measurement. Ratio scale of measurement. What is the difference […]
What is the amount of heat required to raise the temperature of 1 gram of water from 14.50 C to 15.50 C?
Is work done when you lift an object?
Which are characteristics of a ray when it hits a boundary and refracts but not?
Which are characteristics of a ray when it hits a boundary and refracts but not? F. Only these two options are characteristics of a ray when it is refracted, but not when it is reflected. In fact: Reflection occurs when a ray hits the interface between two mediums and bounces off back. When it is […]
What is the point of neutrons?
What is the point of neutrons? Neutrons bind with protons and one another in the nucleus via the nuclear force, effectively moderating the repulsive forces between the protons and stabilizing the nucleus. How quickly does a neutron bomb kill? two days Is there a doomsday bomb? In a 2-part episode of the TV show The […]
What is the 2nd harmonic also referred to?
What is the 2nd harmonic also referred to? Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic. Which generators have the lowest THD rating? The A-iPower […]
Which kind of investigations allow for the control of variables?
Which kind of investigations allow for the control of variables? Answer Expert Verified An experimental investigation allows you to control the variables. Explanation: Experimental investigations include a method in which a “fair test” is created and variables are actively planned, managed, and measured in an attempt to gather testimony to confirm or negate a causal […]
What is a good crop productivity index?
What is a good crop productivity index? CSR2 ranges from 5 (least productive) to 100 (most productive). CSR2 lets farmers and landowners easily compare productivity across farms. For example, a farm with an average CSR2 of 85 is significantly more productive than one with an average CSR2 of 60. How do you define productivity? Productivity […]
Why is my house so full of static electricity?
Why is my house so full of static electricity? Static increases when the air gets cold and humidity drops. To stay warm in your home, you turn up the heat, further adding to a decrease in humidity and increasing static. While static can be annoying and sometimes painful, there are some simple things you can […]
