Answer:
129,600kg/day
Explanation:
The river is flowing at 30.0
1 m³ is equivalent to 1000L
flowrate of river = 30*1000 =30,000L/s
Convert L/s to litre per day by multiplying by 24*60*60
flowrate of river = 30,000 * 24*60*60 L/day
= 2,592,000,000L/day
if the river contains 50mg of salt in 1L of solution
lets find how many mg of salt Y is contained in 2,592,000,000L/day
by cross multiplying we have
Y=
Y= 129,600,000,000 mg/day
convert this value to kg/day by dividing by 1 million
Y= 129,600,000,000/1000000
Y= 129,600kg/day
Answer:
Explanation:
Force is equal to mass times acceleration.
By dividing both sides by m, we rearrange the formula for a (acceleration).
The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.
- A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².
The mass is 2300 grams, but we need to convert it to kilograms.
- To convert grams to kilograms, divide by 1,000
- 2300 g/1000= 2.3 kg
Substitute the values into the formula.
Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).
Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7
The acceleration is about <u>2.7 meters per second squared.</u>
