No
It means the resultant electrical charges had canceled each other out so there is no field to be sensed .

⤥ We use different types of devices in our life to make our work easier. A spade is used to dig , a broom is used to sweep , a hammer is used to pass a nail on the wall and a plank is used to drag a load up to a certain height. All these simple things or devices , which are used in our daily life are called simple machines. Such simple machines do not do our work themselves but we have to use force on them to work with them. Thus , Simple machines are those tools or devices which make our work easier and convenient to do in the direction of force.
Hope I helped ! ッ
Have a wonderful day / night ♡

Answer:Convection
Explanation:
Convection is the heat transfer procedure by the movement of liquid or gas molecules. It is a combination of diffusion and bulk motion of molecules. Near the surface of the liquid diffusion process dominates while at certain height bulk motion of liquid dominates.
Convection can be
Natural : Natural convection occurs due to density differences
Forced: Force convection occurs when we apply external heat source.
Both matter and light have been demonstrated to exhibit wave-like and particle-like behavior.
Light as a wave: light can diffract & refract
Light as a particle: photoelectric effect, Compton scattering
Matter as a wave: Davisson-Germer experiment
Matter as a particle: find a picture of any kinematics problem in a high school physics textbook
Choice D
Answer:
The balloon will collapse
Explanation:
When air is removed from the bell jar, the balloon will collapse if the internal pressure from the balloon does not balance the atmospheric pressure from the surroundings.
