Answer:
10⁴ Pa
Explanation:
When the tank is half filled ,
- Volume = 5m * 4m * 1m = 20m³
Also we know that ,
- Density of water = 10³ kg/ m³
Density = Mass/Volume
10³ kg/m³ = m/20m³
m = 2 * 10⁴ kg
So that ,
Weight = mg
F = 2*10⁴ × 10 N
F = 2 * 10⁵ N
And ,
Pressure = Force/Area
P = 2 *10⁵/ 5 * 4 Pa
P = 10⁴ Pa
Density is mass per unit volume,
so to get the volume, divide the mass by the density,
So the volume is
charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer:
1. I notice nothing because is no picture it probably didnt work
2. idk
