Answer:
The weight of an automobile, W = 17640 N
Explanation:
Given that,
The mass of an automobile, m = 1800 Kg
The weight of an object is represented as the gravitational force acting on an object of mass 'm'. It given by the formula
W = m x g newton
Where,
g - acceleration due to gravity.
Substituting the given values in the above equation
W = 1800 Kg x 9.8 m/s²
= 17640 N
Hence, the weight of the automobile, W = 17640 N
2) solution gets broken down to solute and solvent.
Answer:
i. The magnetic force of repulsion.
ii. The magnetic force of attraction.
Explanation:
A magnet is a material that has the attraction and repulsion capability. Magnets has two poles, north and south, thus would attract or repel another magnet in its neighborhood. It can either be a permanent or temporal magnet, and attracts ferrous metals.
i. In the case of two combinations where two ends are the same, it could be observed that the two ends (poles) repels each other. Thus since like poles repels, magnetic force of repulsion is felt.
ii. In the case of one combination in which the two ends are different, the two ends (poles) attract. Since unlike poles attracts, magnetic force of attraction is observed.
