1)separate the sugar+pepper from the rocks by washing rocks with water and collect all water rinsed off the rocks. 2)with the water from step 1, pour it through a filter with holes smaller than the pepper and again collect the water. 3)boil the sugar-water mixture until all water has evaporated.
Answer:
B is a false statement
Explanation:
Because the law of energy conservation state that energy can neither be created nor destroyed
Answer:
To show that magnets repel, you must place the strong and weak magnets to another magnet with their poles being both south or both north facing eachother.
To show they attract, place opposite poles near eachother.
The speed of a transverse wave( v) = 117.03 m/s
The formula we can use in this case would be:
v = sqrt (T / (m / l))
Where,
v = is the velocity of the transverse wave = unknown (?)
T = is the tension on the rope = 380 N
m = is the mass of the rope = 86.0 g = 0.086 kg
l = is the length of the rope = 3.1 m
Substituting the given values into the equation to search for the speed v:
v = sqrt (380 N/(0.086 kg /3.1 m))
v = sqrt (380 * 3.1/ 0.086)
v = sqrt (13,697.67)
v = 117.03 m/s
speed of a transverse wave( v) = 117.03 m/s

Answer:
a) F=0N
b) F=2N pointing to the ground.
c) F=2N pointing to the ground.
Explanation:
a) The apple is at rest at your hand. This is because the force of gravity is pulling the apple down with a force of 2N, but your hand is aplying to the apple an equal but opposite force of 2N that is the normal force, which points up. If we sum these forces: F=2N-2N=0N in the vertical axis. This null force has no preferred direction.
b) The only force acting over the apple is the force of gravity, which has a value of F=2N for this apple and always points to the ground.
c) Even if the apple is moving upwards, the only force acting on it is the force of gravity, which has a strength of F=2N for the apple and points always to the ground.
