How much force is in a Newton? It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the […]
What are the conditions to form ionic bond Class 11?
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 […]

Where does electric potential equal zero? The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.

What is Plasmolysis give an example?
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 law of conservation of momentum give an example?
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 […]
What are the significant figure rules?
What are the significant figure rules? To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant. Which value from his calculation most strongly affects […]
What is the freeze/thaw cycle?
What is the freeze/thaw cycle? What is a freeze-thaw cycle? A freeze-thaw cycle is when the temperature fluctuates from above freezing (32F), to below freezing, and then back to above freezing. This is considered one freeze-thaw cycle, and Minneapolis, Minnesota experiences several freeze-thaw cycles each year. What do freeze/thaw cycles result in? Freeze-thaw cycles can […]
