Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s

Answer:
g = 0.85 m
Explanation:
g =
were; g is the acceleration due to Earth's gravity, G is Newton's gravitation constant (6.674 x N), M is the mass of the earth (5.972 x kg), and h is the distance of meteoroid to the earth.
h = 3.40 x R
= 3.40 x 6371 km
h = 21661.4 km
= 21661400 m
Thus,
g =
=
= 0.84944
g = 0.85 m
The acceleration due to the Earth's gravitation is 0.85 m.
Answer:
a) The resistance of the calf between the electrodes is
b) The average resistivity of this part of the leg is
Explanation:
Hi
a) Using Ohm's law , solving for , we obtain
b) The volume of the calf is like a cylinder, so , with and , therefore . Then we can use , this is the average resistivity of this part of the leg.
