ANSWER: vaporization
EXPLANATION: Matter changes between the liquid and gas states through vaporization and condensation. Vaporization As liquid water is heated, its temperature rises. until it reaches 100°C. At this point, liquid water changes into water vapor. The change from a liquid to a gas is known as vaporization

A certain frictionless simple pendulum having a length L and mass M swings with period T. If both L and M are doubled, what is t
vampirchik [111]

The new period is D) √2 T

\texttt{ }

<h3>Further explanation</h3>

Let's recall Elastic Potential Energy and Period of Simple Pendulum formula as follows:

\boxed{E_p = \frac{1}{2}k x^2}

where:

<em>Ep = elastic potential energy ( J )</em>

<em>k = spring constant ( N/m )</em>

<em>x = spring extension ( compression ) ( m )</em>

\texttt{ }

\boxed{T = 2\pi \sqrt{ \frac{L}{g} }}

where:

<em>T = period of simple pendulum ( s )</em>

<em>L = length of pendulum ( m )</em>

<em>g = gravitational acceleration ( m/s² )</em>

Let us now tackle the problem!

\texttt{ }

<u>Given:</u>

initial length of pendulum = L₁ = L

initial mass = M₁ = M

final length of pendulum = L₂ = 2L

final mass = M₂ = 2M

initial period = T₁ = T

<u>Asked:</u>

final period = T₂ = ?

<u>Solution:</u>

T_1 : T_2 = 2\pi \sqrt{ \frac{L_1}{g} }} : 2\pi \sqrt{ \frac{L_2}{g} }}

T_1 : T_2 = \sqrt{L_1} : \sqrt{L_2}

T : T_2 = \sqrt{L} : \sqrt{2L}

T : T_2 = 1 : \sqrt{2}

\boxed {T_2 = \sqrt{2}\ T}

What is an equilibrant
professor190 [17]
The question seems to be what is an equilibrant force.

The answer is "an added force that produces equilibrium.

Here you have more insight:

<span>an object that has no net force acting on it? This object indeed is in equilibrium but the object is not the equilibran force.

the reaction force in an action-reaction pair of forces?

the reaction force is not an equilibrant force. The reaction force exists always but equilibrium is only possible if the net force is cero.

an added force that produces equilibrium? this is the right  answer.</span>

some antarctic explorers heading due south toward the pole travel 50. km during the first day. A sudden snow storm slows their p
user100 [1]

Answer:

<h2> 145km</h2>

Explanation:

The displacement is a vector quantity, it tells how far away from a point a distance or a destination is

given that the distance covered are

50. km, 30. km, and 65 km

the displacement is expressed as

= 50+30+65

=145km

We actually performed straight addition because in all the movement the antarctic explorers did not record any deviation from the initial direction, hence they maintained a linear movement from the beginning to the end

Please answer<br>my quastions​
Neko [114]

Answer:

a) 120 N

b) 5 N

c) 0.2 N

d) Mass remains the same, and weight decreases.

Explanation:

<em>Use the formula W = mg, where mass is in kg, and gravitational field strength in N/kg.</em>

a)

W = mg

= 12 × 10

= <u>120 N</u>

b)

500 g = 0.5 kg

W = mg

= 0.5 × 10

= <u>5 N</u>

c)

20 g = 0.02 kg

W = mg

= 0.02 × 10

= <u>0.2 N</u>

d)

<u>Mass remains the same, and weight decreases.</u>
