Answer:
3 m/s²
Explanation:
Sum of forces in the x direction:
∑F = ma
68 N − 23 N = (15 kg) a
a = 3 m/s²
Answer:
Explanation:
Given
mass of block
Force
Force is applied at an angle of
Displacement of block
coefficient of kinetic friction
Friction force acting on block
where N=Normal reaction
Work done by friction
Negative sign indicates that displacement is against the direction of force.
Answer: Covalent Bonds or Covalent Bonding Electrons
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
