Water pressure in a lake is greater __________. a. at the bottom b. at the surface c. at any point, for pressure is the same d.

sweet-ann [11.9K]

Answer:

The correct answer a

Explanation:

In the fluid pressure is a measure of force per unit area, in this case force is the weight of the fluid that increases as we descend. Therefore, the pressure increases with the depth of the fluid.

In an arcade game a 0.099 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releas

Sonja [21]

Answer:

The speed of disk is 1.98 $\frac{m}{s}$

Explanation:

Given:

Mass of $m = 0.099$ kg

Spring constant $k = 244 \frac{N}{m}$

Compression of spring $x = 4 \times 10^{-2}$ m

From energy conservation theorem,

Spring potential energy converted into kinetic energy,

$\frac{1}{2} m v^{2} = \frac{1}{2} k x^{2}$

$v = \sqrt{\frac{k x^{2} }{m} }$

$v = \sqrt{\frac{244 \times 16 \times 10^{-4} }{0.099} }$

$v = 1.98 \frac{m}{s}$

Therefore, the speed of disk is 1.98 $\frac{m}{s}$

Which action can humans take to reduce wave erosion?

mezya [45]

The action that humans can take to reduce wave erosion is to build breakwaters in the ocean.

<h3>What is erosion?</h3>

The term erosion has to do with the washing away of top soil either by water or by wind. The control of erosion is a very important soil conservation effort.

Hence, the action that humans can take to reduce wave erosion is to build breakwaters in the ocean.

Assume that the pictured magnet is being moved into the solenoid. If the polarity of the magnet is reversed and then moved into

KonstantinChe [14]

Answer:

The direction of induced emf is revered and hence the direction of the induced current.

Explanation:

If the polarity of the magnet is reversed, the direction if the field lines through the solenoid is also reversed, which according to Faraday's law means

$\varepsilon =N\dfrac{d\Phi}{dt} \rightarrow -N\dfrac{d\Phi}{dt}$

in other words, the direction of the magnetic flux is revered, and therefore, the direction of the induced emf is also revered.

Furthermore, according to Ohm's law

$I = \dfrac{\varepsilon}{R}$

which tells us that if the induced emf changes sign <em>(is reversed)</em>

$I = -\dfrac{\varepsilon}{R}$

the direction of the induced current is also reversed.
