Part 1
If water does not spill at the top point of the circular motion then for the minimum speed condition we can say normal force will be zero at the top position
given that
R = 1 m
g = 9.8 m/s^2
now from above equation we have
Part b)
for minimum value of angular speed we will have
Answer:
1) Coal is a natural resource, so is wood, wind energy, soil, salt, fluorite, water, and copper
2) Solar energy, natural gas, and wind energy are all renewable
3) Salt is non - renewable as is synthetic diamonds and plastic
4) I think it would be number
5) Based on their mineral, chemical, and textural composition
Explanation:
Hope this helps :)
Answer:
98N and 147N
Explanation:
We have the following information:
We can find the static fricton force as follow,
Where N is the normal force (mg)
Static friction force at 147N is greater than the force applied hence body does not move.
Answer:
Removing some of the books reduced the mass of the box, and less force was needed to push it across the floor.
