Enzymes can increase the rate of a reaction by lowering the activation energy needed for the reaction
Answer:
Part a)
Part b)
Explanation:
Magnetic field due to outer solenoid inside it is given as
Now similarly we have
magnetic field due to inner solenoid on it axis is given as
Part a)
Now if a proton is revolving around the common axis of two solenoids
then we will have
Part b)
Now proton is revolving in the field of outer cylinder only
so again we have
B. Static friction force - static friction is the force put on an object to keep that same object at rest
A rader gun will determine the speed.
