Acar goes from 20m/s to 30m/s in 10 seconds what is its acceleration
prohojiy [21]

Acceleration = change in velocity/change in time

                     = (30 - 20) / 10 - 0

                      = 10 / 10

Acceleration = 1 m/s²

When a certain rubber band is stretched a distance x, it exerts a restoring force of magnitude f = ax, where a is a constant. th
Veseljchak [2.6K]
Given:
F = ax
where
x = distance by which the rubber band is stretched
a =  constant

The work done in stretching the rubber band from x = 0 to x = L is
W=\int_{0}^{L} Fdx = \int_{0}^{L}ax \, dx = \frac{a}{2}  [x^{2} ]_{0}^{L} =  \frac{aL^{2}}{2}

Answer:  \frac{aL^{2}}{2}

A microscope has an objective lens with a focal length of 14.0mm . A small object is placed 0.80mm beyond the focal point of the
Nikolay [14]

Answer:

A. 260 mm

B. - 18

C. 175

Explanation:

A

The expression for the lens equation is

\frac{1}{f} = \frac{1}{u} + \frac{1}{v}

\frac{1}{14.0mm} = \frac{1}{14.80 mm} + \frac{1}{v}

\frac{1}{v} = \frac{1}{14.0} - \frac{1}{14.80}

v = 259 mm

   = 260 mm or 26 cm (to 2 s.f)
