Answer:
to the right
Explanation:
The balls collide in a completely inelastic collision, in other words they have the same velocity after the collision, this velocity has a magnitude V.
We need to use the conservation of momentum Law, the total momentum is the same before and after the collision.
In the axis X:
(1)
For velocity vs Time graphs, the displacement of the object from 2 seconds to 6 seconds is 30 m.
<h3>What is displacement?</h3>
The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.
In velocity time graphs, the displacement is the area under the curve of the graph on the x axis.
'
A line starts at (0, 2) and ends at (6, 8) in v-t graph
Displacement is equal to the area of a triangle and a rectangle formed under the line.
Area = 1/2 base x height + length x breadth
Area = 1/2 x 6x 6 + 6x2
Area = 18 +12
Area = 30 m
Thus, the displacement is 30 m.

Answer:
I believe the answer is B.
Its called gauge pressure
Answer:
When the heat is heated it will be melted of ice, why it still remain at a constant temperature of 0◦ C.
Explanation:
Solution
The heat given by the heater will be used in melting of the ice, therefore the temperature will remain the same at the degree of 0◦ C.
After the ice is fully melted, the temperature of water will begin to increase with time.
