What is the formula for maximum profit? To obtain the profit maximizing output quantity, we start by recognizing that profit is equal to total revenue (TR) minus total cost (TC). Given a table of costs and revenues at each quantity, we can either compute equations or plot the data directly on a graph. How do […]
Is the law of reflection applicable to all mirrors?
Is the law of reflection applicable to all mirrors? It is a fact that laws of reflection are applicable to all reflecting surfaces. Is law of reflection valid for all kind of mirror? The laws of reflection hold good for all the mirrors irrespective of their shape (i.e. flat or curved). The angle of incidence=angle […]
Does Homework take away free time?
Does Homework take away free time? Rather than motivating students to master material and learn efficiently, homework negatively impacts students by taking away from personal time that is necessary for them to lead balanced lives. Is HW good or bad? In fact, too much homework can do more harm than good. Researchers have cited drawbacks, […]
Does rubber hold heat?
Does rubber hold heat? A material that does not let heat and electricity travel through it easily is known as an insulator. In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Plastic, rubber, wood, and ceramics are good insulators. What is […]
What plant is sugar made from?
What plant is sugar made from? There are two major sugar crops: sugar beets and sugar cane. However, sugar and syrups are also produced from the sap of certain species of maple trees, from sweet sorghum when cultivated explicitly for making syrup and from sugar palm. Is chocolate a natural resource? Cocoa is considered a […]
What is Mac in data link layer?
What is Mac in data link layer? The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It controls the transmission of data packets via remotely shared channels. It sends data over the network interface card. What is LLC and MAC […]
How long should you wait between warm up and exercise?
What is the best way to describe a metallic bond?
What is the best way to describe a metallic bond? A metallic bond is the sharing of many detached electrons between many positive ions, where the electrons act as a “glue” giving the substance a definite structure. It is unlike covalent or ionic bonding. Metals have low ionization energy. Therefore, the valence electrons can be […]
Which two changes would increase the density of water?
Which two changes would increase the density of water? The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes. What are the two major factors that cause density changes […]
What are 3 things that elements in the same column have in common?
What are 3 things that elements in the same column have in common? Explanation: For the elements in column 1,2 and 13-18 the atoms in the same column have the same amount of outermost electrons, called valence electrons. Atoms in column 1 (H, Li and Na for example) have 1 valence electron. Column 2 have […]
