Air resistance is a force that slows down objects moving through the air. ... Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent. An object with more surface area will have more air resistance.
Answer:
Electron groups could be considered as Lone pair electrons and bonded pairs of electrons.
Answer: Option D & B
Explanation:
The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.
I got this from another brainly user
Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
The box fall with acceleration 10m/s2 due to gravity
velocity/ 6.1 = 180
velocity = 1098 m/s
the answer is A.
Answer:
Please find the answer in the explanation.
Explanation:
Balancing the forces acting on a body is not enough to establish equlibrium because of the principle of moment say that:
1.) For equilibrium to be attained, the sum of clockwise moment must be equal to the sum of anticlockwise moments.
2.) The sum of upward forces must be equal to the sum of the downward forces
According to the definition of moment, is the product of force and perpendicular distance.
Therefore, the perpendicular distance is needed to be considered.
