As we age the fat pad underneath the bones at the front of our feet (metatarsal heads) and under the heel bone become thinner or “migrate” away from where they are most needed
The centripetal force acting on a 1.5 kg mass moving in a circular path is 27N
A centripetal force is a net force acting on an object in order to maintain the object's movement in a circular motion.
According to Newton's first law, it states an object will continue to proceed its movement in a straight line unless acted upon by an external force.
The centripetal force is the external force at work here and It's the net force that propels the object in a circular motion.
Using the formula for calculating centripetal force:

Explanation :
A circuit is the representation of the path of the flow of current. The circuit can be either closed or open.
When the switch is off the circuit is closed circuit and when the switch is not connected the circuit is open.
The items that are sufficient to make a circuit are as follows :
- Voltage source like a battery.
- Resistors or electrical equipment like heater, motor etc.
Other components can be ammeter, voltmeter, ac source, variable resistors etc.
