Answer:
C is the best suited to the characteristics given in the question
Explanation:
Agricultural chemistry studies on both agriculture which deals with the production of plants and chemistry which controls the raw materials in food and drinks. Agricultural chemistry also investigates environmental changes and emphasizes the studies to explain interactions between plants and animals in nature.
Answer:
60 m
Explanation:
Arthur and Betty will be walking for the same amount of time t
Speed of Arthur = 3 m/s
Speed of Betty = 2 m/s
Distance = Speed × time
Distance covered by Arthur = 3t
Distance covered by Betty = 2t
Distance that Arthur and Betty will cover will be 100 m
3t+2t = 100
⇒5t = 100
⇒t = 100/5
⇒t = 20 s
So, Arthur and Betty will be walking for 20 seconds
Spot is by Arthur's side and keeps running in between them until they meet. So, Spot will be running for 20 seconds and the displacement covered will be the distance covered by Arthur which is
3t = 3×20 = 60m
Displacement is the shortest distance between two points so, Spot's displacement will be 60 m
Answer:
0.0473m
Explanation:
345 ml = 0.000354 m3
6.5 cm = 0.065 m
20g = 0.02 kg
Since can is half filled with water, the water volume is 0.000354 / 2 = 0.000177 m cubed
Let water density be 1000kg/m3, the mass of this half-filled water is
1000*0.000177 = 0.177 kg
The total water-can system mass is 0.177 + 0.02 = 0.197 kg
For the system to stay balanced, this mass would be equal to the mass of the water displaced by the can submerged
The volume of water displaced, or submerged can is
0.197 / 1000 = 0.000197 m cubed
Then the volume of the can that is not submerged, aka above water level is
0.000354 - 0.000197 = 0.000157 m cubed
The base area of the can is
The length of the can that is above water is
0.000157 / 0.003318 = 0.0473 m
Answer:
Shape, Volume
Higher Density
Strong Force
Solids have a higher melting point
The diffusion is slow for another solid

A box is sliding up an incline that makes an angle of 14.0° with respect to the horizontal. the coefficient of kinetic friction between the box and the surface of the incline is 0.180. the initial speed of the box at the bottom of the incline is 2.20 m/s. how far does the box travel along the incline before coming to rest?
