Answer:
You never know if the medication could make you worse
Explanation:
Use the formula n = c / v, where c is the speed of light and v is the speed of light in the environment, that is, use the speed in brackets and the correct answer will be the one that will be the smallest result
Answer:
0.4 km/h
Explanation:
Speed is defined as distance moved per unit time and can be expressed in either m/s or Km/h or miles/h
Mathematically,
where d represent distance covered and t is time taken
Taking d as 100 m and converting it into km, we divide by 1000 hence d= 0.1 km
Time is 15 minutes and to convert to hours we divide by 60 hence 0.25 hours
Speed,
Therefore, the speed is equivalent to 0.4 km/h
To solve this problem we will apply the concepts related to the kinematic equations of linear motion. Where speed is described as the distance traveled in a given time, and the successive equivalences that can be made under that equation.
The distance traveled by the girl with in the given time is
The distance covered by the boy with in the given time is
Since the boy will travels with twice the speed of the girl
Half way between the two rafts at the beginnings is
The final distance between the two rafts at the instant the boy reached the central point of the line joining between them is
Therefore the distance that there is between the two rafts when the first one reaches the toy is 10.5m
Answer:
-6C
Explanation:
We are given that
Charge on an object,Q=-8C
Charge on one piece of object=
We have to find the exact charge of the other piece.
Let q be the charge of second piece of object.
By conservation of charge
Initial charge=Final charge
Substitute the values then we get
Hence, the exact charge of the other piece=-6C
