Hello everyone! I have a question about science; In a video game, a flying coconut moves at a constant velocity of 20 meters/second in a positive direction. The coconut hits an obstacle and moves in the opposite direction with a constant velocity of 10 meters/second. What’s the change in velocity of the coconut?

A.
-30 m/s
B.
-10 m/s
C.
10 m/s
D.
30 m/s

How many electrons does silver have to give up in order to achieve a sido noble gas electron configuration

Select the correct answer. which statement is true about a polarized object? o a. it gains electrons and becomes negatively charged. ob. it gains protons and becomes positively charged. oc. the number of positive and negative charges can be the same. od. it has to be a metal. o e. there is no change in the distribution of the charge in the object. reset next what

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.
