Answer:
<h2>16kg</h2>
Step-by-step explanation:
This problem is borers on elasticity of materials.
according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>
where F is the applied force in N
k is the spring constant N/m
e is the extension in meters
Given data
mass m= 24kg
extensnion=15cm in meters= =
we can solve for the spring constant k
we also know that the force F = mg
assuming
therefore
We can use this value of k to solve for the mass that will cause an extension of
Step-by-step explanation:
<h3> a) [ -6 +22 – 6 + 8 ] ÷ ( -9 )</h3>
[ -6 +22 – 6 + 8 ] = 18
18 ÷ (-9) = -2
<h3> b) 400 ÷ { 40 – (-2) -3 – ( -1)} </h3>
{40 – (-2) -3 – ( -1)} = { 40 + 2 -3 + 1} = 40
400 ÷ 40 = 10
<h3>c) 40 x -23 + 40 x -17 </h3>
(40 x 23) + (40 x -17)
920 + (-680)
= 240
<h3>d) 1673 x 99 – (-1673) </h3>
(1673 x 99) + 1673
1673 x 100
= 167300
<h3>e) 490 x 98 = 48020</h3>
Hope this helps ^-^
