Is negative mass antimatter?
No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity.
There is, though, the method of effective mass or apparent mass, which can be negative. When an object is submerged in water, its apparent weight is decreased by an amount equivalent to the weight of water it displaces. For instance, if a 10-pound rock is dropped into a bucket of water and displaces one pound of water, the effective weight of the rock under water is nine pounds.
If W is atomic weight and N is the atomic number of an element, then: (1) Number of e -1 = W- N (2) Number of 0 n 1 = W- N (3) Number of 1 H 1 = W-N (4) Number of 0

A dragster begins from rest and accelerates for 4.0 s at a rate of 5.0 m/s2. It then travels at a constant speed for 2.5 s. A parachute opens, stopping the vehicle at a constant ra
Why is extended source use in Newtown ''s ring experiment?
When we move from a positive charge towards an equal negative charge along the line joining the two then initially potential reduces in magnitude and at centre changes into zero, b
