Isn't 0 the maximum? And it's formula is -GMm/r which implies that it should be negative right? Also. How are gravatational potential and potential energy related?
The equation for the enthalpy of solution is. E= hydration energy - lattice energy so if the value of hydration energy is greater than the lattice energy then the enthalpy of solution will be positive. As a general rule, the more positive the enthalpy of solution is, the higher is the...
Yeah what's the general equation for it? Is it the cross product of the position vector of any point on a plane and the direction vector? Isn't the direction of line l the same as the direction vector A?
A question from s1:
A committee of 6 ppl, which must contain at least 4 men and at least 1 woman, is to be chosen from 10 men and 9 women.
A) find the no of possible committed that include either Albert(man) or tracey(woman) but not both.
Yeah so in the parallel circuits there were 2 in one loop and 1 in the other so the total potential energy was 2V right? But them there were two more resistors (in series with each other) and if they were both equal to 3V the total pd could be 8V
Wait wait gain in kinetic energy was equal to the loss in potential energy...and it lost 1/4th of its potential energy when it gained 1/4th of its kinetic energy so .5*4*4=8 and 1/4th of that is 2J which is equal to .5*2*2 so that's why I marked B
I marked C the 10^6 one...the answer I was getting wasn't close to any of the answer choices! It was either C or D tho cause the other two were really small values
Hey what about that strain question. The young modulus of the two objects were 5.0 Nm2- and 30.0 Nm2- I think and we had to find the total tensile stressor something
