Answer : The variables used in the equations for centripetal acceleration are, radius and tangential speed.
Explanation :
Centripetal acceleration : It is defined as any object moving in a circular path will have some acceleration vector that pointed towards the center of the circle.
Formula used for centripetal acceleration is,
where,
= centripetal acceleration
r = radius of path
v = velocity or speed of an object or tangential speed
In the equation of centripetal acceleration, the radius and tangential speed are the variables.

To solve this problem we will apply the concepts related to gravity according to the Newtonian definitions. From finding this value we will use the linear motion kinematic equations to find the time. Our values are
Comet mass
Radius
Rock was dropped from a height 'h' from surface = 1m
The relation for acceleration due to gravity of a body of mass 'm' with radius 'r' is
Where G means gravitational universal constant and M the mass of the planet
Now calculate the value of the time
The time taken for the rock to reach the surface is t = 87.58s
Answer:
Magnetic field at the center of the loop
Explanation:
It is given that total length of wire is 2 m and number of circular loop is 5 turns.
Therefore ,
We know , magnetic field at the center of loop is given by :
Putting all values in above equation we get :
Hence , this is the required solution.
