Can anyone please provide assistance with the following related rates questions?
1. For the given mass of gas in a cylinder pv^1.5=400 where p is the pressure in Nm^-2 and v is the volume in cubic metres. If the pressure increases at 3Nm^-2 per minute find the rate at which the volume is changing at the instant when the pressure is 50 Nm-2.
2. Wheat runs from a hole in a silo at a constant rate and forms a conical heap whpse base radius is treble the height. If after 1 minute, the height of the heap is 20 cm, find the rate at which the height is rising at this instant.
Any help would be greatly appreciated thankyou.
