Since acceleration = Vf- Vi/t
Vf = 75m/s
Vi = 30m/s
Then acceleration = 75-30/5
= 9m/s.
1 mA = 0.001 A
Therefore, 5 mA = 0.001 * 5
=0.005 A
Resistance = voltage / current
= 100 / 0.005
= 20000 ohms
Current = voltage / resistance
= 25 / 20000
= 0.00125 A (or) 1.25 mA
Answer:
Explanation:
The electric force on a charged particle is given by
where
q is the charge of the particle
E is the strength of the electric field
In this problem, we have
is the electric field strength
is the charge of the calcium ion
Therefore, the electric force exerted on the calcium ion is
Answer:
The bone marrow produces stem cells, the building blocks that the body uses to make the different blood cells. The erythropoietin sends a message to the stem cells telling more of them to develop into red blood cells.
