Answer:

A vacuum was created in a glass tube by means of a pump. A feather and a gold coin (a guinea) placed inside the tube were dropped at the same time. The two bodies, despite their very different weights, reached the base of the tube together.

The water in this pot is in the process of changing from a liquid to a gas. Thermal energy is still being added to the water as
olga nikolaevna [1]

The extra energy allows the molecules to convert states of molecules.

<h3>What is heating?</h3>

When the temperature is increased , the body or particle is said to be heating.

The water in this pot is in the process of changing from a liquid to a gas. Thermal energy is still being added to the water as it vaporizes, but its temperature and the motion of its particles are not increasing.

When the liquid is converted to gas, the temperature reaches the boiling point of water. After boiling, the heat added up will only make the particles to convert its phase and go away in then atmosphere.

Thus, extra energy added helps molecules of water to change its state from liquid to solid.

1. A 2m-long and 3m-wide horizontal rectangular plate is submerged in water. The distance of the top surface from the free surfa
ExtremeBDS [4]

Answer:

864 KN

Explanation:

(Absolute pressure) = (Atmospheric pressure) + (Gauge Pressure)

Atmospheric pressure = 95 KPa = 95000 Pa

Gauge Pressure = ρgh

ρ = density of the fluid = 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = depth below the fluid level that the object is at = 5 m

Gauge Pressure = 1000 × 9.8 × 5 = 49000 Pa

Absolute pressure = 95000 + 49000 = 144000 Pa.

Pressure = (Hydrostatic force)/(Area perpendicular to the force)

Hydrostatic force = (Pressure) × (Area perpendicular to the force)

Area perpendicular to the force = 2 × 3 = 6 m²

Hydrostatic force on the top of the plate = 144000 × 6 = 864000 N = 864 KN

Hope this Helps!!!

A stone is dropped into water from a bridge 52 m above the water's
dusya [7]

Answer:

Its final velocity and how much time it takes to reach the water

Explanation:

The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:

v^2-u^2=2as

where

v is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2 is the acceleration of gravity

s = 52 m is the distance covered during the fall

Solving for v,

v=\sqrt{u^2+2as}=\sqrt{0^2+2(9.8)(52)}=31.9 m/s

We can also find how much time it takes to reach the water, using the equation

v=u+at

where

v = 31.9 m/s is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2

t is the time

And solving for t,

t=\frac{v-u}{a}=\frac{31.9-0}{9.8}=3.26 s

Bailey walks to the pizza place for lunch. To get there, she walks 3 km East, then 8 km south, and then 3 Km East again
sveticcg [70]

Answer:

Total distance she cover = 14km

Magnitude of displacement = 10 km

Direction of her displacement is East-south

Explanation:

Given:

Distance travel (East) = 3 km

Distance travel to south = 8 km

Distance travel (East) = 3 km

Computation:

Total distance she cover = 3km+8km+3km

Total distance she cover = 14km

Magnitude of displacement = \sqrt{(3+3)^2+(8)^2}\\

Magnitude of displacement = 10 km

Direction of her displacement is East-south
