A 24.0 cm long screwdriver is used as a lever to open a can of paint. If the fulcrum is 0.500 cm away from the end of the screwd
ELEN [110]

The ideal mechanical advantage of the screwdriver is 47

Explanation:

In this problem, the screwdriver acts as a lever.

The Ideal Mechanical Advantage (IMA) of a lever is given by:

IMA=\frac{d_i}{d_o}

where:

d_i is the distance of the point of application of the input force from the fulcrum

d_o is the distance of the output force from the fulcrum

In this problem, we have:

d_o = 0.500 cm, since the fulcrum is 0.500 cm from the end

d_i = 24.0 cm - 0.500 cm = 23.5 cm (the distance between the fulcrum and the point where are we holding the screwdriver)

Substutiting,

IMA=\frac{23.50 cm}{0.50 cm}=47

Calculate the following forces for a box with a mass=20.0 kg sitting on an incline of 29.0 degrees and a coefficient of friction
Anna007 [38]
Vertical force on the box=mg 
<span>the component of gravity parallel=mg*SinTheta </span>
<span>the component of gravity normal=mg*CosTheta </span>
<span>frictional force up the plane: mg*cosTheta*mu max, but if it is sitting still, it is equal and opposite to mg*cosTheta (it cannot be greater than this or it would go up the plane).</span>

what will happen to the pressure in a gas if you compressed it into a volume that was one third the size? why?​
Annette [7]

Answer:

Pressure will triple   (Boyle's Law)  

Explanation:

Assuming a constant temperature:  (compressing gases usually raises the temp significantly):

P1V1 = P2V2

P1V1 / V2   = P2      

   Now change V2  to 1/3 V2:

P1V1 / (1/3 V2 ) = P2 / (1/3 )

P1V1/ (1/3 v2 ) = 3 P2                <======= THE PRESSURE WILL TRIPLE

    This is Boyle's Law

A 500 kg car starts with a force of 1000 N
Nadya [2.5K]

Answer:

2 m/s²

30 m/s

Explanation:

1) F = ma

1000 N = (500 kg) a

a = 2 m/s²

2) Given:

v₀ = 0 m/s

a = 2 m/s²

t = 15 s

Find: v

v = at + v₀

v = (2 m/s²) (15 s) + 0 m/s

v = 30 m/s
