Answer:
Explanation:
Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures.
Even with all of these state changes, it is important to remember that the substance stays the same—it is still water, which consists of two hydrogen atoms and one oxygen atom. Changing states of matter are only physical changes; the chemical properties of the matter stays the same regardless of its physical state!
 
        
             
        
        
        
Answer:
Mass of the climber = 69.38 kg
Explanation:
Change in length
         
Load, P = m x 9.81 = 9.81m
Young's modulus, Y = 0.37 x 10¹⁰ N/m²
Area
        
Length, L = 15 m
ΔL = 5.1 cm = 0.051 m
Substituting
         
  
Mass of the climber = 69.38 kg
 
        
             
        
        
        
Answer:
C. 3.2 x 10^8 Ω•m
Explanation:
An insulator is a material that resists the flow of electricity.
In the given data the material with the highest resistivity is the best insulator
3.2 x 10^8 Ω•m
 
        
             
        
        
        
Answer:the force is needed to stretch it farther.
Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.
