A stone of mass 600g is thrown vertically upwards. calculate the value of the gravitational force on the stone at its highest point. take g = 10N/kg

6N

Explanation:

F = m × g

= 0.6 × 10

= 6N

to find the force you first have to convert the mass to kg by dividing 600 by 1000 giving you 0.6

then you can multiply the mass times the gravity giving you a gravitational force of 6N

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
