It might make more sense putting it another way but this is basically it. you just take the minutes and divide them by 60 to convert them to hours. then simplify the ratio

You are taking care of two small children, Sarah and Rachel, who are twins. On a nice cool, clear day you decide to take them ro
BlackZzzverrR [31]

Answer:

Explanation:

Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.

Force = mass x acceleration

Apply this equation on Rachel

T₁ = 23 x 2 = 46 N

Let T₂ be tension between Sarah and me and it is inclined at 60°

Force = mass x acceleration

Apply this equation on Sarah

T₂ cos 60 - T₁ = 23 X 2 = 46

T₂ cos 60 - 46 =46

T₂ cos 60  = 92

T₂ = 92 / .5

= 184 N

On a part-time job, you are asked to bring a cylindrical iron rod of density 7800 kg/m3 , length 81.7 cm and diameter 2.70 cm fr
Genrish500 [490]

Answer:

35.792 N

Explanation:

d = Diameter of rod = 2.7 cm

h = Length of rod = 81.7 cm

\rho = Density of rod = 7800 kg/m³

g = Acceleration due to gravity = 9.81 m/s²

Volume of rod

V=\dfrac{1}{4}\pi d^2h\\\Rightarrow V=\dfrac{1}{4}\times \pi\times (2.7\times 10^{-2})^2\times 81.7\times 10^{-2}

Mass is given by

m=\rho V\\\Rightarrow m=7800\times \dfrac{1}{4}\times \pi\times (2.7\times 10^{-2})^2\times 81.7\times 10^{-2}\\\Rightarrow m=3.6486\ kg

Weight is given by

W=mg\\\Rightarrow W=3.6486\times 9.81\\\Rightarrow W=35.792\ N

The weight of the rod is 35.792 N
