Determine the magnitude of the weight of a 3.0 kg object on earth. a) 3.0 n b) 29 n c) 3.3 n d) 0.31 n

B) 29 N

Explanation:

Weight is a vector quantity. Weight have both magnitude and direction. The weight of an object is the force of attraction towards the object. it might be gravity or reaction force.  The SI unit of weight is Newton . Weight can be can be calculated when you multiply the mass of an object and the gravitational acceleration. The weight of a particular object varies with location but the mass of the an object is same in any location. The weight of an object is measured with a scale.

Since the mass of the object is given , the weight can be calculated.

W = mass ×  gravitational acceleration

W = mg

m = 3.0 kg

g = 9.8 m/s²

w = 3.0 × 9.8

w = 29.4  N

answer is c

explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
