What happens to drag when speed increases? With an increase in speed comes an increase in drag and a decrease in net force. This decrease in net force reduces acceleration. What is the perfect aerodynamic shape? For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has […]

What are the factors affecting the kinetic energy of an object Brainly? The amount of kinetic energy depends on mass and speed. What is kinetic energy of an object derive an equation to express kinetic energy? E=1/2mV2. What is the kinetic energy of an object class 9? Hint:Kinetic energy is the energy that an object […]

Is AgOH a salt base or acid? Cards Term List the common strong acids. Definition HCL (hydrochloric acid), HBr (hydrobromic acid), HI (Hydroiodic “), HNO3 (Nitric acid), H2SO4 (Sulfuric acid), HClO4 (perchloric acid) Term Which of the following are strong bases? LiOH, AgOH, Pb(OH)2, NaCl, KOH, CaOH, NaOH Definition LiOH, KOH, NaOH Is Al3+ acidic […]

Can you would you could you? The most proper way to use these words is to use “could” if you’re not sure if the person is able to do something. If you know the person is capable of doing what is asked, then it’s better to use “would”. What is the difference between must and […]

What is the effect of a deletion mutation? A deletion changes the DNA sequence by removing at least one nucleotide in a gene. Small deletions remove one or a few nucleotides within a gene, while larger deletions can remove an entire gene or several neighboring genes. The deleted DNA may alter the function of the […]

How can you tell how old a sheep is? You can tell approximately how old a sheep is by looking at its teeth. Sheep have four pairs of incisors on their lower jaw, a dental pad (no teeth) on their upper jaw, and grinding teeth on the back part of their jaw. When lambs are […]

Can you make oxygen from water? This is possible using a process known as electrolysis, which involves running a current through a water sample containing some soluble electrolyte. This breaks down the water into oxygen and hydrogen, which are released separately at the two electrodes. How is the strength of hydrogen bonds determined? Order of […]

Can earthquakes be tracked? Seismic waves lose much of their energy in traveling over great distances. But sensitive detectors (seismometers) can record theses waves emitted by even the smallest earthquakes. When these detectors are connected to a system that produces a permanent recording, they are called seismographs. Where is an earthquake most likely to occur? […]

What is a good heat insulator? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator […]

Can skeletal muscle repair itself? It has been known for more than a century that skeletal muscle, the most abundant tissue of the body, has the ability to regenerate new muscle fibers after it has been damaged by injury or as a consequence of diseases such as muscular dystrophy (1). Which cell types is responsible […]
