1. Which type of motion do soldiers in a parade show? Ans. Soldiers in a parade show rectilinear motion. Is marching periodic motion? Periodic motion repeats itself after a fixed interval of time but in the marching, soldiers are moving in forward direction, so there is not repetition of motion.Read More →
As to where the equation for the critical speed comes from (if you are interested), consider the net force in circular motion. We know this is always the centripetal force, which points radially inward. The centripetal force causes centripetal acceleration and is necessary for the object to keep moving inRead More →
Dealing With Diarrhea Although it doesn’t cause miscarriage, diarrhea can affect a pregnancy. An occasional loose stool can be normal, but if you have any of the following, call your doctor: Diarrhea for more than 3 days. Fever of 100.4 F or higher. What are the signs of pregnancy inRead More →
When a body agrees to postpone a matter to a specific time, it has ordered that the future agenda include the item. When a matter is tabled, it is set aside and the body doesn’t specify when or whether it will take up the matter again. What happens if aRead More →
Most models will continuously perform as intended, but power outages, inclement weather and age can cause them to fail. Use these tips to reset your motion sensor lights, and in most cases, they’ll be working correctly again in a matter of minutes. How do I reset my motion light staysRead More →
Newton’s third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. … We sometimes refer to this law loosely as action-reaction, where the force exerted is the action and the forceRead More →
If an object covers equal distances in equal intervals of time then it is said to be uniform motion. Example:- A person who is jogging and then walking. If an object covers unequal distances in equal interval of time then it is said to be non- uniform motion. What isRead More →
Rub your baby’s gums with your finger or a washcloth dipped in cold water to ease the pain. Have your baby chew on a chilled teething toy, cold spoon, or chilled fruit in a mash feeder. How much diarrhea is normal with teething? The common perception among dentists is thatRead More →
If the forces that are acting on the body, are equal in magnitude and opposite in direction, the net force will be 0. This is the scenario of balanced forces. In such a case, the net force acting on the body is 0 and hence there is no change inRead More →
