Explanation:

We have, Billy the friendly Robot uses 50 N of force to lift a box 2 meters in the air.

It is required to find the work done by Billy.

Work done by an object is given in terms of force and displacement. The formula used to find the work done is given by :

W=Fd\\\\W=50\ N\times 2\ m\\\\W=100\ J

So, the work performed by Billy is 100 J.

According to the octet rule, which of elements will have a tendency to loss 2 electrons?
Aneli [31]
The correct option is STRONTIUM.
Strontium is a group 2 element, that means it has two electrons in its outermost shell. This element will prefer to lose these two electrons in its outermost shell in order to attain the octet form, therefore, it will form electrovalent bond with non metals which it can donate two electrons to.

what is ( H+) and (OH-) in a healthy person's blood that has a PH of 7.50 assume that the temperature of the blood is 298 K.
AlekseyPX

pH = - log [H⁺]

pH = 7.5

\tt [H^+]=10^{-7.5}=3.16\times 10^{-8}

pH + pOH = 14

7.5 + pOH = 14

pOH = 6.5

\tt [OH^-]=10^{-6.5}=3.16\times 10^{-7}
