A. 15 N
B. 6.5 N
C. 11.3 N
D. 147 N

Answer :

Answer:

14.7 N

[tex]solution \\ mass = 1.5 \: kg \\weight = m \times \: g \\ \: \: \: \: \: \: \: \: \: \: \: \: = 1.5 \times 9.8 \\ \: \: \: \: \: \: \: \: \: = 14.7 \: newton[/tex]

hope this helps...

Good luck on your assignment...

Given:

  • Mass,m = 1.5 kg

  • Acceleration due to gravity,g = 9.8 m/s² [ constant ]

To find out:

Find the weight?

Formula used:

Weight = m × g

Solution:

Weight of book = m × g

Putting the values in the above formula,we get:

Weight of book = 1.5 × 9.8

= 15/10 × 98/10

= 1,470/100

= 14.7 kg.m/s²
