Answer: its 15 i think i hope this helps
Explanation:
As an example, the distance from Earth to the Sun is about 150,000,000,000 meters – a very large distance indeed. In scientific notation, the distance is written as 1.5 × 1011 m.
Explanation:
The concentration of salt after t minutes is given by :
A tank contains 9000 L of pure water. Brine that contains 40 g of salt per liter of water is pumped into the tank at a rate of 25 L/min.
We need to find the concentration approach at
So,
Put
Since,
C(t) = 40 g/L
So, at the concentration approaches to 40 g/L. Hence, this is the required solution.
1. is 75 km/h because 150 divided by 2 is 75
3. the second person since he ran the same distance in less time
4. a.True b.False c.True
Answer:
the emf will be
Explanation:
We have given radius of the coil r = 3.6 cm = 0.036 m
So area
Number of turns N = 600
Emf is given by
So the emf will be
