A is the correct answer: 100 degrees C is the boiling point of water, just subtract 82 from 100.
Answer:
Explanation:
Given

Determine the difference in the blood pressure from feet to top
This is calculated using Pascal's second law.
The second law is represented as:
Subtract P1 from both sides
Where
P2 - P1 = Blood Pressure Difference
So, the expression becomes:
Hence, the difference in blood pressure is approximately 
Answer:
no energy is lost or gained when molecules collide
molecules are constant, linear motion
Explanation:
Answer:
C) seems to be the correct one
Each alpha particle emitted decreases the mass of the nucleus by 4 and decreases the atomic number by 2.
Also, each beta particle will increase the atomic number by 1.
So if C emits 5 alpha particles the atomic mass decreases by 20 and the atomic number decreases by 10. Then emission of 2 beta particles brings the atomic number up to minus 8.
So a total of 7 particles have been emitted and the number of alpha particles emitted exceeds the number of beta particles emitted.
Explanation:
A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.
