13. Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass
on top of the block and pulled it 50 cm across the table. Which of the following
changes to their setup would result in a larger force reading on the spring scale?
Bock with 10g mass
Force shown on
spring scale
50cm

1.Sliding the block 60 cm

2.Using a bigger spring scale,

3.Using a 20 g mass

4.Using a circular piece of wood,

this is a good question! i'll do some research and come back when i have the answer!

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
