Answer:
Uniform velocity involves a straight-line motion over equal distance and in equal time intervals. Non-uniform motions involve unequal distances in equal interval of time.
Explanation:
A body moving with uniform velocity occurs when it travels in a straight line path, and covers equal distances in equal time intervals.
Example a graph of a bike covering equal distance in equal time intervals.
A body moving with a non-uniform velocity occurs when it travels to cover unequal distance in equal intervals of time. Example a bike travelling in a crowded road.
2.6 seconds (If acceleration due to gravity is taken 10 m/s^2) or 2.65 (If acceleration due to gravity is taken 9.8 m/s^2)
Upper mantle
The theory of the plate tectonics uses the convection cells in the upper mantle layer as the foundation for the movement of the continents.
To put it simple the process is explained like the convection cells create a lot of pressure, that pressure, supported by the high temperatures and magma, influence the crust above, and manage to crack it on certain places. As the crust cracks, it becomes a separate entity, and under the enormous force from bellow it slowly moves into a particular direction, and that is actually the movement of the tectonic plates.
Answer:
Equivalent resistance of this circuit is 1.6 ohms.
Explanation:
In the given figure, the three resistors are connected in parallel with 12 Volt battery. In parallel combination of resistors, the potential difference across each resistor is same but the current across each resistors divides.
The equivalent resistance is given by :
Here, R₁ = 3 ohms, R₂ = 6 ohms and R₃ = 9 ohms
Hence, the equivalent resistance of this circuit is 1.6 ohms.
