The answer is False.  Simple machines are divided into three main categories, and not two.  They are Levers, inclined planes and Pulleys. <span>These three simple machines all change force in such a way that it makes it easier for us to move an object. </span>

You have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weight 3
LenaWriter [7]

Answer:

0 Joules

Explanation:

The work done is given by

W=F\times s\times cos\theta

where,

F = Force applied

s = Displacement of the object = 0 m

\theta = Angle between the force applied and the horizontal = 0

W=F\times 0\times cos0\\\Rightarrow W=0\ J

Work is only observed when there is a displacement.

The work done by me is 0 Joules as I was unable to move it.

Which atoms have the highest electronegativity?
Ronch [10]

Answer:

Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).

A stone with a mass m is dropped from an airplane that has a horizontal velocity v at a height h above a lake. If air resistance
seropon [69]

Answer: Option B. R = (1/2)gt^2

Explanation:

S = R (horizontal distance)

V^2 = 2gS

V^2 = 2gR

R = V^2 / 2g

But V = gt

R = (gt)^2 / 2g

R = (g^2 x t^2) / 2g

R = gt^2 / 2

But t^2 = 2h/g

R = ( g x 2h/g) / 2

R = h

But h = (1/2)gt^2

R = h = (1/2)gt^2
