Consider a=70 cm·kg and b=35 mg·km identify which operations are possible, and which are not. if the operation is possible, also check the given result. examples: you cannot add 5m and 3s, so "this operation is impossible." you can add 5m and 3cm, so "this operation is possible" - however, the answer 8m would false. you can divide a by b, and get 20 you can multiply a and b, and get 0.0245 m·kg you can add a and b2, and get 0.701225 m·kg you can multiply a and b, and get 0.0245 m2kg2 you can add a and b, and get 0.735 m·kg

Which of the following is an example of units for speed

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r

Agroup of monkeys is trying to cross the river in a rowboat. the maximum buoyant force on the rowboat is 2,000 n. the weight of the rowboat is 1,000 n. each monkey has a weight of 150 n. how many monkeys can safely cross in the rowboat at one time? explain your reasoning, including any calculations you used to find the answer.
