A blast breaks a body initially at rest of mass 0.5kg into three pieces , two smaller pieces of equal mass and the third double the mass of either of small piece . After the blast two smaller masses move at right angles to one another with equal speed . Find the statements that is/are true for this case assuming that the energy of blast is totally transferred to masses. All the three pieces share the energy of blast equally The speed of bigger mass is √2 times the speed of either of the smaller mass The direction of motion of bigger makes an angle of 135° with the direction of smaller pieces The bigger pieces carries double the energy of either pieces

class 10 video  what ohm's law? Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as, objective question based on electric current open this link for objective    https://nexttopperinstitute.blogspot.com/2020/07/class-10th-objective-questions-on.html   Class 10       HOW TO ORGANISM REPRODUCE Question. 1(i) What is fertilisation? Distinguish between external fertilisation and internal fertilisation. (ii) What is the site of fertilisation in human beings? Answer. (i) Fertilisation is defined as the fusion of a male gamete (sperm) with a female gamete (an ovum or egg) to form a zygote during sexual reproduction. (ii) The site of fertilisation in human beings is in the fallopian tube of female reproductive system. Question.2 Define th...
