A 0.110-kg cube of ice (frozen water) is floating in glycerine. The glycerine is in a tall cylinder that has an inside radius of

creativ13 [48]

Answer

Δ h = 0.06 m

Explanation:

Given,

mass of ice cube = 0.11 Kg

inside radius of cylinder = 3.70 cm

density of water = 1000 Kg/m³

density of glycerin = 1260 Kg/m³

ice cube is floating on glycerin surface,

net force on the cube is equal to zero.

Buoyant force by glycerin is equal to the weight of cube

B = W

$\rho_g V g = m g$

$\rho_g (\pi r^2 h_1)= m$

$h_1= \dfrac{m}{\rho_g\pi r^2}$

$h_1= \dfrac{0.11}{1260\pi\times 0.037^2}$

h₁ = 0.0203 m

when ice melts it is completely turned into water

Volume of mass m of water

$V = \dfrac{m}{\rho_w}$

$\pi r^2 h_2 = \dfrac{m}{\rho_w}$

$h_2 = \dfrac{m}{\rho_w\pi r^2}$

$h_2 = \dfrac{0.11}{1000\pi\times 0.037^2}$

h₂ = 0.0803 m

distance by which height of liquid change

Δ h = h₂ - h₁

Δ h = 0.0803 - 0.0203

Δ h = 0.06 m

When you drop an object from a certain height, it takes time T to reach the ground with no air resistance. If you dropped it fro

alexandr402 [8]

Answer:

Explanation:

Given

When we drop an object from height , suppose h

it takes time T

using equation of motion

$h=ut+\frac{1}{2}at^2$

where

$h=displacement$

$u=initial\ velocity$

$a=acceleration$

$t=time$

here $u=0$ because it dropped from a certain height

$h=\frac{1}{2}gT^2$

$T=\sqrt{\frac{2h}{g}}$

When height is increases to three times of original height

i.e. $h'=3 h$

then time period becomes

$T'=\sqrt{\frac{2\times 3h}{g}}$

$T'=\sqrt{3}T$

A vertical spring with a spring constant of 310 N/m is mounted on the floor. From directly above the spring, which is unstrained

EleoNora [17]

Answer:

7.3cm above the compressed spring.

Explanation:

We can use the conservation energy theorem to solve this problem:

$U_{1}+K_1=U_e+U_2+K_2\\m*g*h+0=\frac{1}{2}k*x^2+0+0\\\\h=\frac{k*x^2}{2*m*g}\\\\h=\frac{310N/m*(3.6*10^{-2})^2}{2*0.28kg*9.8m/s^2}\\\\h=0.073m$

The block was dropped 7.3cm above the compressed spring.
