Answer:
5 m/s²
Explanation:
Use the acceleration formula: ![a=\frac{v_f-v_i}{t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv_f-v_i%7D%7Bt%7D)
- vf = final velocity (m/s)
- vi = initial velocity (m/s)
Based on the information given to us by the prompt, we know:
Substitute these values for the variables to calculate the acceleration:
![a=\frac{30-10}{4}\\\\a=\frac{20}{4}\\\\a=5](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B30-10%7D%7B4%7D%5C%5C%5C%5Ca%3D%5Cfrac%7B20%7D%7B4%7D%5C%5C%5C%5Ca%3D5)
Therefore, the acceleration of the bus is 5 m/s².
Answer:
Chemical formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's chemical formula cannot be reduced any more, then the empirical formula is the same as the chemical formula. Combustion analysis can determine the empirical formula of a compound, but cannot determine the chemical formula (other techniques can though). Once known, the chemical formula can be calculated from the empirical formula.

Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
Answer:
acceleration a = 1,557 m/s²
Explanation:
Let's use the kinematic equations, the initial distance is 70 m (Xo = 70 m), also if the track is 2200m long or 100m long when clearing use a distance in the path of
X = 2200-100-70 = 2030 m
With this data let's calculate the acceleration
Vf² = Vo² + 2 a X
the jet leaves the rest (Vo=0=
a = Vf2 / 2X
a = 80 2/2 2030
a = 1,557 m/s²
