I think it’s B. I apologize if I’m wrong.
Answer:
a) J=
b) F =
c) The force is 2551.02 times bigger than the weight of the pollen grain.
Explanation:
a) we know that the impulse J is equal to:
J =
where M is the mass, is the final velocity and the initial velocity. So, replacing values, we get:
J =
J =
J=
b) We know that the force is equal to:
F = J/t
where J is the impulse and t the time. So, replacing values, we get:
F =
F =
c) The weight W of the pollen grain is calculated as:
W =
W =
So, if we compare the force and the weight of the pollen grain, we get:
it means that the force is 2551.02 times bigger than the weight of the pollen grain.
Resistance is current x potential difference. So therefor run wafff
Answer:
False. Its your body, you do what you want. Wanna lose weight? Then do some reasearch. Wanna keep how body how it is? Then keep it. Its your body
