a. The clay is less dense when stretched into the shape of a boat.
b. The buoyant force is greater on the clay when it has a spherical shape.
c. The boat shape displaces a greater volume of water than the ball shape.
d. The weight of the clay boat is less than the weight of the clay ball.
Answer:
c. The boat shape displaces a greater volume of water than the ball shape.
Explanation:
An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.
Answer:
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration for nitrogen with atomic number of 7 which also contains 7 electrons is:
b. electron
c. neutron
d. magnetic domain
Answer:
Option D is the correct answer.
Explanation:
An atom consists of nucleus and electrons revolving around it.
Nucleus is filled with proton and neutron.
So atom consists of electron, proton and neutron.
Magnetic domain is not present in an atom.
Option A,Option B and Option C are present in an atom.
Option D is not present in an atom.
So Option D is the correct answer.
Two factors that affect the moment of force are the magnitude of the force applied and the distance from the axis of rotation at which the force is applied.
