maximum allowed value of the speed in roller coaster is given as
now from kinematics we can say
here initial speed will be
acceleration is due to gravity
now we can use this to find the height
so maximum allowed height will be 20.4 m
While a bug fly in the air the weight of bug is counter balanced by the buoyancy force that is applied by air on the bug
This buoyancy force is net upthrust on the bug due to air which will help the bug to float in the air
This buoyancy force is given by the formula
here we know that
= density of air
V = volume of bug
so here we can say that upthrust of air is the force that bug will experience during his uplift
Answer:
Explanation:
Given data
Force= 10N
mass= 4kg
r= 4*9.81
r= 39.24N
The expression for the force acting is expressed as
substitute
Electromagnetic Spectrum?
