What happens after condensation to cause precipitation

Answer:

the acceleration of gravity on Planet X is 19.89 m/s^2

Explanation:

The computation of the acceleration of gravity on Planet X is shown below:

T = 2π√l ÷ √g

g = l ÷ (T÷ 2π)^2

= 4π^2l ÷ T^2

= 4π^2× 0.2 ÷ 0.63^2

= 19.89 m/s^2

Hence, the acceleration of gravity on Planet X is 19.89 m/s^2

In this way it should be calculated

Answer:

El neumático soportará una presión de 1.7 atm.

Explanation:

Podemos encontrar la presión final del neumático usando la ecuación del gas ideal:

[tex] PV = nRT [/tex]

En donde:

P: es la presión

V: es el volumen

n: es el número de moles del gas

R: es la constante de gases ideales

T: es la temperatura

Cuando el neumático soporta la presión inicial tenemos:

P₁ = 1.5 atm

T₁ = 300 K

[tex] V_{1} = \frac{nRT_{1}}{P_{1}} [/tex]  (1)  

La presión cuando T = 67 °C es:

[tex] P_{2} = \frac{nRT_{2}}{V_{2}} [/tex]   (2)

Dado que V₁ = V₂  (el volumen del neumático no cambia), al introducir la ecuación (1) en la ecuación (2) podemos encontrar la presión final:

[tex] P_{2} = \frac{nRT_{2}}{V_{2}} = \frac{nRT_{2}}{\frac{nRT_{1}}{P_{1}}} = \frac{P_{1}T_{2}}{T_{1}} = \frac{1.5 atm*(67 + 273)K}{300 K} = 1.7 atm [/tex]  

Por lo tanto, si en el transcurso de un viaje las ruedas alcanzan una temperatura de 67 ºC, el neumático soportará una presión de 1.7 atm.

Explanation:

There are 2 ways to help with this. Explain the details, which are fairly simple in this topic, or give the formula. My hope is that an explanation will last longer than memorizing the formula. I give you both.

If a wave has frequency, f, of 3 Hz, its period, T, is

. The wavelength,

λ

, is 5 meters. That means that in the time of one period, the wave travels 5 m.

In general,

In applying this general definition of speed

to a wave, we have

speed of the wave

=

wavelength

period

Note: we generally use v for speed of a wave. Using the variable names, then that last formula is written

v

=

λ

T

Since

T

=

f

, we can also say that

v

=

λ

⋅

f

So, using that last formula

v

m

s

Note: the unit Hz is equivalent to what it was called 100 years ago,

cycles

(

also cps

)

. Cycles is not a true unit, so the Hz contributed only the "per second" to the result

15

m

s

.

Answer: the speed is =30ms^-1 The speed of a wave is given by "speed" (ms^-1)= "frequency(Hz)" xx "wavelength (m)" The frequency is f=100Hz The wavelength is lambda=0.3m The speed is v=lambdaf=0.3*100=30ms^-1

Answer:

Humans survive through gaining nutrients by eating

Answer:

We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive.  Oxygen is one of the most essential human needs. Our bodies need a consistent supply of it to function properly. Without access to oxygen, you can experience a condition known as cerebral hypoxia, which affects the brain. As little as five minutes without air can result in brain damage. We get food from plants and animals, we get water from rivers and streams, and we get shelter from building anything that is around.

Answer:

Procedures 4 and 5.

Explanation:

Both would cause the box to move up.

4, it becomes lighter

5, the other becomes heavier, pulling it down, causing box one to go up

Since we seek the action of force to push up box 1, the students observes an unbalanced upward force on Box 1 in procedures 4 and procedure 5.

Generally, In procedure 4 we added another mass to the box two, therefore, causing box one to experience an upward force.

Therefore, students observe an unbalanced upward force on Box 1 in procedure 4.

Procedure 5 we remove masses from box 1 resulting in box 2 becoming heavier, pulling it down.

Therefore, students observe an unbalanced upward force on Box 1 in procedure 5.

Remember that moment before collision is equal to the moment after collision.

[tex](m1 \times u1) + (m2 \times u2) = (m1 \times v1) + (m2 \times u2)[/tex]

Plugging in our values,

[tex](6 \times 4) - (3 \times 2) = (6 \times 1) + (3 \times v2) \\ 24 - 6 = 6 \times 3v2 \\ 18 = 18v2 \\ v2 = 1 {ms}^{ - 1} [/tex]

The velocity of the second car after the collision is 8 m/s.

The law of conservation of momentum states that, within the domain, the total momentum before collision is equal to the momentum after collision.

Here,

Mass of the car to the right, m₁ = 6 kg

Mass of the car to the left, m₂ = 3 kg

Velocity of the first car before collision, u₁ = 4 m/s

Velocity of the second car before collision, u₂ = 2 m/s

Velocity of the first car after collision, v₁ = 1 m/s

According to the conservation of momentum,

(m₁u₁) + (m₂u₂) = (m₁v₁) + (m₂v₂)

(6x4) + (3x2) = (6x1) + (3v₂)

3v₂ = 24

Therefore, v₂ = 24/3

v₂ = 8 m/s

Hence,

The velocity of the second car after the collision is 8 m/s.

Answer: The crest of one wave overlaps with the trough of another

Explanation:

I took the test and got 100%. This is the correct answer

The best description of the destructive interference of light is the crest of one wave overlaps with the trough of another.

Destructive interference takes place when waves come together in such a manner that they completely cancel each other out or amplitude of the resulting wave decreased.

The highest surface part of a wave is called the crest, and the lowest part is the trough.

Explanation:

Kinetic energy=1/2mass*speed squared

KE=1/2mv^2

Data,

M=0.65kg

V=?

85J=1/2(0.65kg)V^2

Cross multiply

2 *85=0.65V^2

Divide both sides by 0.65

Answer:

η = 0.882 = 88.2 %

Explanation:

The efficiency of the pulley system can be given as follows:

[tex]\eta = \frac{W_{out}}{W_{In}}\\\\[/tex]

where,

η = efficiency of pulley system = ?

W_out = Output Work = (600 N)(0.6 m) = 360 J

W_in = Input Work = (35.7 N)(11.43 m) = 408.051 J

Therefore,

[tex]\eta = \frac{360\ J}{408.051\ J}[/tex]

η = 0.882 = 88.2 %
