None of those choices is applicable. 'A' is the closest, but it doesn't really do the job. The object is moving with constant speed. If the horizontal line happens to coincide with the x-axis, then the constant speed is zero.

How much work is needed to push a 117- kg packing crate a distance of 2.75 m up an inclined plane that makes an angle of 28 o wi

Nataly_w [17]

Answer:

$W_{tot,min} = 1481.372\,J$

Explanation:

The minimum total work is the work needed to counteract the work associated with the weight:

$W_{tot, min} = W_{F}$

$W_{tot,min} = m\cdot g\cdot \sin \theta \cdot \Delta s$

$W_{tot,min} = (117\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (\sin 28^{\textdegree}) \cdot (2.75\,m)$

$W_{tot,min} = 1481.372\,J$

What is the voltage across an 8.00 nm–thick membrane if the electric field strength across it is 5.50 MV/m?

polet [3.4K]

Answer:

0.044 V

Explanation:

E = Electric field = $5.5\times 10^6\ V/m$

d = Thickness of membrane = 8 nm

When the electric field strength is multiplied by the membrane thickness we get the voltage

Voltage across a gap is given by

$V=Ed\\\Rightarrow V=5.5\times 10^6\times 8\times 10^{-9}\\\Rightarrow V=0.044\ V$

The voltage across the membrane is 0.044 V
