Average speed = (total distance covered) / (total time to cover the distance)
= (2,742 km) / (4.33 hours)
= (2,742 / 4.33) km/hr
= 633 km/hr (rounded)

According to the statement of OHM's Law,
The current in an electric circuit is directly proportional to the voltage across that circuit. This means, larger the voltage , more will be the current flow. Mathematically this can be stated as:
I = V/R
Here 1/R is the constant of proportionality and R represents the Resistance of the circuit.
This equation is also stated in texts as:
V = IR
So, the correct answer is option A. Voltage
Chemical weathering weakens the outer surfaces of rocks and its primary agent is water. Mechanical weathering is carried out by impact or attrition by water and air.
Both of these forms of weathering combine and cause rocks to obtain a spherical shape.The concentric layers of rock are combined to form structures known as saprolite.
