the person i admire most in the world is nelson mandela - the president of south arm a during the 1990s. before that he spent more than twenty-five years in prison because of his political beliefs. he wanted to get equal rights for black people in south africa.

the reason that i admire him is that in spite of the fact that he spent such a long time in prison he never changed his views. it would've been quite easy for him to stop campaigning for the rights of black people, but he never did that.

i think he's really influenced the way people think about how they can change politics, by standing by their beliefs and stating them very clearly.

остальное я думаю можно выкинуть-смысл и так сохраняется) кстати мне тоже нравится этот политик, ведь он как никак выступал за права людей, ведь чернокожие люди такими же правами как и мы с вами : )

в 6 раз  так как сила тяжести f=mg в 6 раз меньше. поэтому для передвижения тела той же массы (неважно по горизонтали или вертикали) требуется в 6 раз меньшее усилие.

есть и другие способы решения по формулам например, нахождение отношений высоты прыжка на земле и луне. но этот самый простой и понятный.

плотность вычисляется по формуле  р=m/v,кг/м3

где m-масса, v-объем

250*120*65=1950000мм3=0,00195м3

3,6: 0,00195=1846 кг/м3 плотность кирпича
