Mark has a mass of 55 kg and climbs up a short, steep trailbof length 300 m to reach the top of a 100 m tall cliff. Matthew, his

twin brother, walks up a gentle, winding trail of length 5000 m to reach the top of the same cliff. What is the potential energy of each boy at the top?

This is slightly a trick question.

Potential energy = Mass x gravity x height.

The problem gives us the mass (55kg) and his twin brother we can assume has the same mass (55kg).

It also gives us the height (100m) and acceleration from gravity = 9.81m/s

Akimi4 [234]

Answer:

Selenium dichloride

Explanation:

Selenium (Se) and Chlorine (Cl) are both elements capable of combining together to form a compound with the chemical formula; SeCl2. Since the chlorine atom is more electronegative than selenium atom, the chlorine pulls more electrons towards itself to form an IONIC bond.

The SeCl2 compound formed is called Selenium dichloride as two atoms of Chlorine are needed to combine with one atom of Selenium to form the compound.

What force must be exerted on the master cylinder of a hydraulic lift to support the weight of a 2000-kg car (a large car) resti
Nataliya [291]

Archimedes principle states that

 

F1 / A1 = F2 / A2

F2 = (A2 / A1) * F1

 

Also, formula for the force is F = mg. Formula for the area of the cylinder is A = πr^2, therefore we get

 

F2 = (πr2^2 / πr1^2) * mg

 

Since the diameter of the cylinders are 2 cm and 24 cm, r1 = 12 and r2 = 1.

 

Substituting the values to the derived equation, we get

 

F2 = (π 1^2 / π 12^2) * 2400 * 9.8

F2 = 163.3333 N
