Ok I know this from other stuff potassium nitrate would completely dissolve in a 100 g on was at 30 c would be 60 but this is 40 so I’m not really sure and I don’t what to ok give you a bad grade but if I had to guess I would go with 65 grams
Yes it is true that electrical fences displays a warning about voltage and amperage of the fence. It has to be first understood that power is directly proportional to voltage as well as current. So higher the voltage or higher the current flowing through the fenses, higher will be the power. So any person touching the fence should always be aware of the voltage and current flowing through the fence, otherwise it can be very deadly. Sometimes it can be seen that a high voltage is being passed through the fence and the current passed is comparitively low. This will not decrease the total power flowing through the fence.
Circumference of a circle can be calculated if the radius or the diameter is given.
<u>Explanation</u>:
- Circumference or the perimeter of a circle can be calculated if the radius or the diameter of the circle is given.
- This is calculated by the formula - 2 * pi * r (if radius is given) and pi * d (if diameter is given) where pi = 3.14, r = radius and d = diameter
- This calculation is based on the fact that the circumference is three and a little more times that of the radius. Since the diameter is double that of the radius, when the diameter is given formula becomes pi*d.
Answer:
yes! what are the questions??
Explanation:
Answer:
The average force is 1578.94 N.
Explanation:
Given that,
Mass of baseball = 150 g
Speed = 45 m/s
Speed of pitcher = 60 m/s
Time = 9.5 ms
We need to calculate the average force
Using formula of impulse
...(I)
....(II)
From equation (I) and (II)
Where, m = mass of baseball
= final velocity
= Initial velocity
= time
Put the value into the formula
Hence, The average force is 1578.94 N.
