Does the atomic mass increase as you move across a period? Explanation: As you move across a period, the atomic mass increases because the atomic number also increases. When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom. Which atomic property increases […]

What is Plasmolysis give an example? Some real-life examples of Plasmolysis are: Shrinkage of vegetables in hypertonic conditions. Blood cell shrinks when they are placed in the hypertonic conditions. During extreme coastal flooding, ocean water deposits salt onto land. Spraying of weedicides kills weeds in lawns, orchards and agricultural fields. Does Cytolysis occur in animal […]

What is the formula of isosceles? Area of an Isosceles Triangle Formulas Known Parameters of Given Isosceles Triangle Formula to Calculate Area (in square units) Base and Height A = ½ × b × h All three sides A = ½[√(a2 − b2 ⁄4) × b] Length of 2 sides and an angle between them […]

What is law of conservation of momentum give an example? Conservation of Momentum Examples According to the conservation of momentum, the gun receives a backward momentum. The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero so […]

How self-driving cars will impact society? The prospect of widespread use of driverless cars brings with it many benefits: fewer traffic accidents and the economic toll caused by property damage, injury or death that results. Energy costs will also be saved as these autonomous vehicles maximize driving efficiency and reduce traffic congestion. How much do […]

What are the conditions to form ionic bond Class 11? One of the atoms must be a metal and the other must be a non-metal. The metal atom should have very low ionization energy so that it can lose electrons easily to form cations (positively charged ions) i.e. metal atoms must be highly electropositive. What […]

What temperature rise are we on track for? Greenhouse gas emissions reached a new high last year, putting us on track for an average temperature rise of 3 degrees Celsius. COVID-19 lockdowns are likely to result in just a 0.01C reduction in global warming by 2050. How fast is the global temperature rising? According to […]

Can any LED light be used to grow plants? LED lights are more energy efficient and emit much lower levels of heat than other types of lighting. But can you use any led lights to grow plants? Generally, yes. White light contains a great mix for plants, so white LED bulbs will work to grow. […]

Why is Lake effect snow so bad? The Physics of Lake-Effect Snow Cool air cannot hold as much moisture as warm air. If there is enough moisture, some of it condenses and falls as snow or rain. Is Lake effect snow dangerous? Lake Effect Snow Can Be Dangerous During the storm, more than five feet […]

Is laser light hotter than white light? Laser Light Is Hotter Than White Light. What are three differences between light from an incandescent bulb and light from a laser? A laser generates a beam of very intense light. The major difference between laser light and light generated by white light sources (such as a light […]
