6. for the following graph what can you conclude about the force applied to cause the object’s motion? explain your reasoning
7. graph the information on the following data table and then explain what the slope represents. these data represents the time it takes to hear a thunder after a lighting strikes.

Explanation:

6) I can't read graph A, but I will assume it is similar to graph B. The graph represents the position of an object with respect to time. The slope of this graph represents the velocity of the object. Since the graph is a straight line, the slope of the graph is constant and also the velocity of the object is constant. If the velocity is not changing the force on the object must be zero.

7) I can't see the data table but I will assume it is similar to example (6). In that case, the slope of the graph would represent the speed of the sound.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
