Question
Two billiard balls having the same mass roll toward each other at the same speed. What is the net momentum of the two-ball system? 10 kg middot m/s system 0 kg middot m/s not enough information You use a straw for a pea shooter. The speed of the pea emerging from the straw when you blow through it will be greater if the straw is full length. either cut in half or full length. cut in half. If a ball rolls down an inclined plane and picks up 4 m/s each second it rolls, its acceleration is one half of 4 m/s^2 4 m/s^2 one half of 4 m/s 10 m/s^2 Metals are both good heat and electrical conductors due to relatively high densities of metals. high elasticity of metals. looseness of outer electrons in metal atoms. similar thermal and electrical conductive properties. ability of metals to transfer energy easily. Water pressure at the bottom of a lake depends on the weight of water in the lake. Depth of the lake. Surface area of the lake. all of the above Newton's second law directly involves acceleration. velocity. Speed. none of the aboveExplanation / Answer
70 )
m1v1 + m2v2 = p
here m1 = m2
v1 = -v2
p = 0
73)
metal has tendacy to losse their outmost electron ( C option)
74 )
P = Po + rho*g*h
depth of the lake ( b option )
75 )
sum of all force = ma
A) acceleration
