Answer:
2.5km
Explanation:
Assuming you also walk with the average human walking speed of 5 km/h. We know that speed=distance/time and now making distance the subject, distance is a product of speed and time. The time is 30 minutes, expressed in hours will be 30/60=0.5 hours. Substituting 5km/h for speed and 0.5 hours for time then the diatance covered will be
Distance=5*0.5=2.5 km
Answer:

Explanation:
= magnitude of charge on each proton = 1.6 x 10⁻¹⁹ C
= mass of each proton = 1.67 x 10⁻²⁷ kg
r = distance between the two protons = 1 x 10⁻¹⁵ m
Electric force between the two protons is given as


N
Gravitational force between the two protons is given as


N
Ratio is given as

the second level will have 8 electrons.
K=Frictional Force/Normal Force
Normal force would be mg, since it's not on an incline.
Normal Force = 28 kg*9.8 m/s^2 = 274.4 N
200.3 N/274.4 N = 0.73
