If a mass of 76 kg acts downward 0.38 m from the axis of rotation on one end of a board and another force of 129 N also acts dow
Semenov [28]

Answer:

y = 2.196 m

Explanation:

Mass, m = 76 kg

distance from axis of rotation, x = 0.38 m

Second Force, F = 129 N

moment arm of the second force, y = ?

Now, equating moments for the equilibrium

So,

m g × x = F x y

76 x 0.38 x 9.81 = 129 x y

y = \dfrac{76\times 0.38\times 9.81}{129}

y = 2.196 m

Hence, the length of the moment arm is equal to 2.196 m.

Need help quick plz 100pts!!!!
Daniel [21]

Answer:

60°C

Explanation:

The dish starts at 110°C and goes down to 50°C

This is the term : 110°C - 50°C

Since 110-50=60, the answer is 60°C

The equation is 110°C - 50°C = 60°C

Extra:

I'm not an expert on this so I'm sorry if it's wrong!
