Answer:
The distance covered when speedwalking for 10 minutes based on the 8 meters trial (assuming a speed of 1 m/s) is 600 meters.
Explanation:
The speed of a body is the distance it covers per unit time when it travels. Its formula is given as; speed = distance/time. Its unit is meters per second as distance is measured in meters while time is measured in seconds.
From this formula, the distance covered by a body travelling with a given speed over a specific time can be determined. Distance = speed × time. This formula applies generally in all cases given the speed of the body and the time it travels.
Speed walking means walking as fast as possible without jogging or running. In this experiment, the speed over the 8 meters trial is not given. However, some assumptions can be made.
Assuming the speed while speedwalking is 1 meters per second; time taken = 10 mins or 10 × 60 seconds = 600 seconds. Distance covered = 1 m/s × 600 s = 600 m
Therefore, the distance covered when speedwalking for 10 minutes based on the 8 meters trial (assuming a speed of 1 m/s) is 600 meters.
Answer:
656,25 moles of CH3OH
Explanation:
If the mixture has 7% of weight in methanol (CH3OH), it means that for every 100 kg of the mixture there are 7 kg of methanol.
To solve the problem we just use this relation and convert the kilograms of methanol to gmoles of methanol using the molecuar weight of the methanol (32g/mol):
Answer:
Valinomycin
Explanation:
This antibiotic is acquired from the Streptomyces species cells. Valinomycin is selective to potassium and inhibits sodium ions from entering the cell. This antibiotic allows the potassium ions to move down the electrochemical potential gradient of the lipid membranes.
Answer:Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
