vovangra [49]

Answer:

900kJ

Explanation:

Work done hereis lifting that water mass on to the surface level

v = volume of the tank

d= density of water (1000kg/m3)

g = gravotational acceleration

workdone=Weight * distance

= (v*d*g)*distance

= $=((\frac{8+4}{2} )*5*10)*1000*10*3\\=900000J\\=900kJ$

Atoms in a solid are in continuous vibrational motion due to thermal energy. At room temperature, the amplitude of these atomic

Bingel [31]

Answer:

10 m/s

Explanation:

Given:

Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]

Frequency of the vibrations (f) = 10¹² Hz

In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.

Therefore, the formula for maximum speed is given as:

$v=f\lambda$

Now, plug in the values given and solve for speed 'v'. This gives,

$v=(10^{12}\ Hz)(10^{-11}\ m)\\\\v=10^{12-11}\ m/s\\v=10\ m/s$

Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
