Answer:
The slope of the position time graph gives the velocity.
Explanation:
The slope of the position time graph gives the value of velocity.
In first graph,
The slope is constant in both the parts but positive . So the velocity is also constant and positive for both the parts. and more than the second part, so the initial velocity is more than the final velocity.
In the second graph,
The slope is constant in both the parts but negative. So, the velocity is constant but negative for both the parts. Initial velocity is more negative than the final velocity.
You should have the velocity as a function of time either given explicitly or implicitly (a graph)
v = ds/dt (differentiating the position vector)
integrating the acceleration.
you can use impulse or work and energy principle and also newton law of motion to find acceleration then velocity
NOT SURE IF THAT WHAT YOU WANT.
Answer:
Velocity

Change in time
Answer:
150 Nm
Explanation:
Unit conversion:
5 cm = 0.05 m
8 cm = 0.08 m
The torque generated by such force would be the product of the force by the muscles and the moment arm of that force.
T = FR
Where T is the torque (Nm), F = 3000 N is the force and R = 0.05 m is the moment arm
T = 3000*0.05 = 150 Nm
The effector strain of bacteria is that the bacteria would colonize on the teeth and help prevent the child from developing cavitie
