Answer:
c. slow the flow of heat from inside the house to the outside.
Explanation:
Thermal insulation not completely stops the flow of heat but slow down the process of flowing of heat from inside the house to the outside.
A nuclear particle with no charge is a neutron
Answer:
Microwave spectroscopy is the spectroscopy method that employs microwaves, i.e. electromagnetic radiation at GHz frequencies, for the study of matter
Explanation:
It is given that,
Electric field, 
We need to find the change in the electric potential energy of the proton-field system when the proton travels to x = 2.5 m
From the conservation of energy, the loss in potential energy is equal to the gain in kinetic energy and kinetic energy is is equal to the work done.
So, the change in electric potential energy of the proton field system is 
. Hence, this is the required solution.
To determine, the final velocity we use one kinematic equation. It would be 2ax = vf^2 - v0^2. The initial velocity would be zero since it starts from rest. Therefore, the equation would be:
vf = √(2ax) where a is the acceleration ( a = g ) and x is the height
vf = √(2)(9.8)(25)
vf = - 22.14 m/s
