Explanation:
entropy is the randomness or disorder of a system right?
we know gases have negligible forces of attraction hence the particle move in an uphazard manner hence there great disorder as compared to liquid with low force of attraction low kinetic energy but in solid particles are held by strong intermolecular forces in fixed position where kinetic energy is low and order is greater here
Answer:
The height from which the rock was thrown is 1.92 m
Solution:
As per the question:
Speed with which the rock is thrown, v = 12.0 m/s
Horizontal distance traveled by the rock before it hits the ground, d = 15.5 m
Launch angle,
Now,
To calculate the height, h from which the rock was thrown:
First, since we consider the horizontal motion in the trajectory of the rock, thus the time taken is given by:
Now,
The height from which the rock was thrown is given by the kinematic eqn, acceleration in the horizontal direction is zero:
The correct answer is A. B. C. Hope this helps!!
I haven't worked out the number, but it won't be necessary ... it's easy to pick the answer out of the choices that are given. ... The time (5 yrs) is less than the half-life (12.35 yrs), so more than half of the original sample (100mg) remains. Only one of the choices is more than 50 mg. (Can you find it ?)
