Tides are strongest when the earth, moon and sun are in line.

<h3>What are tidal waves?</h3>

A tidal wave is a periodically occurring shallow water wave brought on by the ocean's gravitational interactions with the Sun, Moon, and Earth. Despite the fact that tides have nothing to do with tsunamis, the phrase "tidal wave" is frequently used to describe them. A storm surge, storm flood, tidal surge, or storm tide is a tsunami-like occurrence of rising water that frequently occurs along coastlines during low-pressure weather systems like cyclones. It is calculated as the increase in water level over the average tidal level and excludes waves.

A flywheel of J = 50 kg-m2 initially standing still is subjected to a constant torque. If the angular velocity reaches 20 Hz in

Karolina [17]

Answer:

$\tau = 1256.5\ N.m$

Explanation:

given,

J = 50 kg-m²

frequency, f = 20 Hz

time ,t = 5 s

we know,

angular velocity = 2 π f

ω = 2 π x 20

ω = 125.66 rad/s

now, angular acceleration calculation

$\alpha = \dfrac{\omega_f-\omega_i}{t}$

$\alpha = \dfrac{125.66-0}{5}$

α = 25.13 rad/s²

Torque given to the flywheel.

$\tau = I \alpha$

$\tau = 50\times 25.13$

$\tau = 1256.5\ N.m$

Torque of the given flywheel is equal to $\tau = 1256.5\ N.m$

A small block is released from rest from the edge of a large hemispherical frictionless bowl with radius 3 m. As the mass passes

andreyandreev [35.5K]

Explanation:

It is given that,

Radius of bowl, r = 3 m

A small block is released from rest from the edge of a large hemispherical friction less bowl. Let v is the speed of the mass when it passes through the bottom of the bowl and u is the initial speed of the mass, u = 0. Using conservation of energy as :

$mgh=\dfrac{1}{2}mv^2$

h = r = 3 m

$v=\sqrt{2gh}$

$v=\sqrt{2\times 9.8\ m/s^2\times 3\ m}$

v = 7.66 m/s

v = 7.7 m/s

So, the speed of the mass at the bottom of the bowl is 7.7 m/s. Hence, this is the required solution.
