In each of three trials of an investigation, a single force is applied to a mobile. Each time, the mobile acquires a different acceleration. The table shows the relationship between the acceleration and the acting force.
Force (N) Acceleration (m/s)
1.2
4.8
0.7
2.8
1.6
6.4
Which phrase best describes a graph that would represent the relationship shown in the table? (1 point)

O a downward-sloping line drawn on a graph with acceleration shown on the x-axis and force shown on the y-axis
o an upward-sloping line drawn on a graph with acceleration shown on the y-axis and force shown on the x-axis
an upward-sloping line drawn on a graph with acceleration shown on the x-axis and force shown on the y-axis

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?

Area around a charged object where the objects can exert a force on another charged objects is an electric
