Answer: If T is the time you wait to trim the lawn since you last did it and B is the lenght at which you trim, then the speed will be:
Explanation:
Let's say T is the time you wait to trim the lawn since you last did it (1 month for example) and B is the lenght at which you trim (10cm for example).
If v is the speed at which the lawn grows, then the lenght of the lawn as a function of time will be:
where 
is an arbitrary initial lenght. Let's say 
.
Then we have:
So, at time T the lawn has grown a lenght B. And the speed is:
<span>gravitational force = 0.1 mg-wt. = 0.1 * 10^-6 * 9.8 N = Gm1m2/r^2
m1 = 40 kg m2 =15 kg and r = 0.2 m
Put in and find G</span>
Moment=Force*distance from the pivot.
Moment 1=500N*2m=1000Nm
Moment 2=1000N*1m=1000Nm
Moment 1=Moment 2
Answer:
Explanation:
Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle
torque is zero as , centripetal force passes through axis of rotation that is center.
So work done by centripetal force = 0
So work done by tension on M = 0
The answer is B- the process of cells making new cells
