Explanation:
En un balde de 25 cm de altura se hace un orificio a 15 cm del suelo.calcula la velocidad de salida del agua
I would say the switch because it turns it on and off
I think the correct answer would be that there are a relatively small number of moles of HCl present. Dilute would mean that there are very few solute particles dissolved as compared to the solvent particles in the solution. Hope this helps.
Answer:
The average velocity of Samuel’s entire trip is 1.16 m/s.
Explanation:
Given:
Distance covered at first checkpoint (d₁) = 925 m
Distance covered at second checkpoint (d₂) = 673 m
Time taken for reaching first checkpoint (t₁) = 10 min = 10 × 60 = 600 s [∵1 min = 60 s]
Time taken for reaching second checkpoint (t₂) = 13 min = 13 × 60 = 780 s
Now, the average velocity of Samuel's entire trip is given by the formula:
![\textrm{Average velocity}=\dfrac{\textrm{Total distance covered}}{\textrm{Total time taken}}](https://tex.z-dn.net/?f=%5Ctextrm%7BAverage%20velocity%7D%3D%5Cdfrac%7B%5Ctextrm%7BTotal%20distance%20covered%7D%7D%7B%5Ctextrm%7BTotal%20time%20taken%7D%7D)
Total distance traveled is equal to the sum of the distances traveled at first and second checkpoints. So,
Total distance covered = ![d_1+d_2=925+673=1598\ m](https://tex.z-dn.net/?f=d_1%2Bd_2%3D925%2B673%3D1598%5C%20m)
Total time taken = ![t_1+t_2=600+780=1380\ s](https://tex.z-dn.net/?f=t_1%2Bt_2%3D600%2B780%3D1380%5C%20s)
Therefore, the average velocity is given as:
![\textrm{Average velocity}=\dfrac{\textrm{Total distance covered}}{\textrm{Total time taken}}\\\\\textrm{Average velocity}=\frac{1598\ m}{1380\ s}\\\\\textrm{Average velocity}=1.16\ m/s](https://tex.z-dn.net/?f=%5Ctextrm%7BAverage%20velocity%7D%3D%5Cdfrac%7B%5Ctextrm%7BTotal%20distance%20covered%7D%7D%7B%5Ctextrm%7BTotal%20time%20taken%7D%7D%5C%5C%5C%5C%5Ctextrm%7BAverage%20velocity%7D%3D%5Cfrac%7B1598%5C%20m%7D%7B1380%5C%20s%7D%5C%5C%5C%5C%5Ctextrm%7BAverage%20velocity%7D%3D1.16%5C%20m%2Fs)
Hence, the average velocity of Samuel’s entire trip is 1.16 m/s.
Answer:
gravity is the invisible force that attracts us the the earth\
1.normal force 2.frictional force 3. spring forces
flowing electrons produce a magnetic field
unbalanced forces are not equal they always cause changes in the moving object like the direction . balanced forces are equal and cause no changes
The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system the meter kilogram second (s), kelvin the ampere , the mole and the candela.
