Explanation:
Answer:
the interaction in the protein is greater than the surface with water
\frac{F_i}{F_s} = \frac{\epsilon_s}{ \epsilon_i} \ > 1
Explanation:
The electric force for a charge is
F =
In the exercise indicate that the charge is q and the distance r is maintained, the test charge is another
therefore if we use the index i for the dielectric constant (
) in the protein
the electric force in water with dielectric constant (
)
if we look for the relationship between these forces
therefore the interaction in the protein is greater than the surface with water
Answer: Open system
According to thermodynamics, if a system exchanges matter and energy with its environment it is an open system. For example, human beings and animals can be considered as open systems, since we take chemical energy in the form of food and perform work on our surrounding environment when moving and doing activities.

Answer:
0.50m/s
Explanation:
Average velocity is the change in displacement of a body with respect to time.
Velocity = ∆S/∆t
∆S = 100m - 70m
∆S = 30m
∆t = 2min - 1 min
∆t = 1min = 60secs
Substitute the given parameters into the formula for velocity
Velocity = 30m/60s
Velocity = 1/2 m/s
Average Velocity = 0.5m/s
