A car drives 90 meters north, then turns around and drives 120 meters south. What was its displacement and distance?
Rufina [12.5K]

Answer:

displacement= 30 m towards south, distance= 210m

Explanation:

Distance (scalar quantity) how much ground an object has covered.

Displacement (vector quantity) refers to how far out of place an object is it is the object's overall change in position.

Basically meaning for displacement the directions will be very key

D for Displacement

D= D1+D2

D=  120 (S) + 90 m (N)

Must be in same direction

D= 120 (S) + (-90 m) (S)

D= 30 m (S)

and for distance you are simply just adding how much distance they have covered

so d= d1+d2

d= 90m + 120m

d= 210m

A neutral atom of uranium (U) has 146 neutrons and a mass number of 238. How many protons does it have?
BARSIC [14]

Answer:

92 protons

Explanation:

The mass number is 238 , so the nucleus has  <u>238  particles</u> in total, including <u>146 neutrons</u>.  So to calculate the number of neutrons we have to subtract:  238  −  146  =  92
