Hurry I need answers quick I’m timed

Answers

Answer 1

Answer:

A). Increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object.

Explanation:

The two objects possessing opposite or unlike charges attract one another due to the electromagnetic force between the electrons, as well as, protons in order to develop ionic lattices.

As per the question, the objects having unlike charges would attract one another more when we 'escalate the positive charge of the object having a positive charge and enhance the negative charge of the object possessing negative charge.' This will lead the atoms that are losing electrons to be positively(+ve) charged and the atoms gaining electrons to be negatively

(-ve) charged. Thus, the electromagnetic force among them increases and a stronger ionic network develops leading them to attract each other more. Hence, option A is the correct answer.

After being struck by a bowling ball, a 1.8 kg bowling pin sliding to the right at 5.0 m/s collides head-on with another 1.8 kg bowling pin initially at rest. Find the final velocity of the second pin in the following situations: a) The first pin moves to the right after the collision at 0.8 m/s. Answer in units of m/s. 010 (part 2 of 2) 10.0 points b) The first pin stops moving when it hits the second pin. Answer in units of m/s

Answers

Answer:

a) v₂ = 4.2 m/s

b) v₂ = 5 m/s

Explanation:

a)

We will use the law of conservation of momentum here:

[tex]m_1u_1+m_2u_2=m_1v_1+m_2v_2[/tex]

where,

m₁ = m₂ = mass of bowling pin = 1.8 kg

u₁ = speed of first pin before collsion = 5 m/s

u₂ = speed of second pin before collsion = 0 m/s

v₁ = speed of first pin after collsion = 0.8 m/s

v₂ = speed of second after before collsion = ?

Therefore,

[tex](1.8\ kg)(5\ m/s)+(1.8\ kg)(0\ m/s)=(1.8\ kg)(0.8\ m/s)+(1.8\ kg)(v_2)\\v_2 = 5\ m/s - 0.8\ m/s[/tex]

v₂ = 4.2 m/s

b)

We will use the law of conservation of momentum here:

[tex]m_1u_1+m_2u_2=m_1v_1+m_2v_2[/tex]

where,

m₁ = m₂ = mass of bowling pin = 1.8 kg

u₁ = speed of first pin before collsion = 5 m/s

u₂ = speed of second pin before collsion = 0 m/s

v₁ = speed of first pin after collsion = 0 m/s

v₂ = speed of second after before collsion = ?

Therefore,

[tex](1.8\ kg)(5\ m/s)+(1.8\ kg)(0\ m/s)=(1.8\ kg)(0\ m/s)+(1.8\ kg)(v_2)[/tex]

v₂ = 5 m/s

The correct answer is: "vibrate".

To find the correct word to complete the sentence, we need to know more about the sound wave.

What is sound wave?

Sound wave is a longitudinal wave i.e. the particles vibrate along the direction of propagation of wave.It requires a material medium to travel i.e. it can not travel in vacuum.

How does sound wave produce?

Sound wave is produced due to variation of pressure in a medium. The high pressure region is compression region and low pressure region is rarefaction region.In case of an object, these pressure variations are produced by its vibration in a medium.

Thus, we can conclude that sounds are made when objects vibrate in air.

Una esfera de aluminio de 250 g a una temperatura de 230 °C se introduce en 450 g de alcohol a una temperatura de 18 °C. Determine la temperatura de equilibrio del sistema. El calor específico del aluminio es 911 J kg-1 °C-1 y para el alcohol 2100 J kg-1 °C-1.

Answers

Answer:

La temperatura de equilibrio del sistema es de aproximadamente 59,17 °C

Explanation:

La masa de la esfera de aluminio, m₁ = 250 g

La temperatura inicial de la esfera de aluminio, T₁ = 230 °C

La capacidad calorífica específica del aluminio, c₁ = 911 J / (kg·°C)

La masa del alcohol, m₂ = 450 g

La temperatura inicial del alcohol, T₂ = 18 ° C

La capacidad calorífica específica del alcohol, c₂ = 2,100 J/(kg·°C)

Observamos que el punto de ebullición del alcohol ≈ 78,37°C

Sea 'T' la temperatura de equilibrio del sistema, obtenemos;

ΔQ₁ = ΔQ₂

ΔQ₁ = Calor transferido desde el aluminio = m₁ · c₁ · (T₁ - T)

ΔQ₂ = Calor transferido al alcohol = m₂ · c₂ · (T - T₂)

∴ m₁ · c₁ · (T₁ - T) = m₂ · c₂ · (T - T₂)

Por lo tanto, por sustitución, obtenemos

250 × 911 × (230 - T) = 450 × 2100 × (T - 18)

Usando una calculadora gráfica, tenemos;

T = 277570/4691 °C ≈ 59,17 °C

La temperatura de equilibrio del sistema, T ≈ 59.17 °C

60.0 kg downhill skier is moving with a speed of 10.0 m/s as she starts her descent from a level plateau at 150.0 meters of height above the base of the slope below. The length of the slope is 650 meters. There is a frictional force of 70 N affecting the skier's motion while she coasts the entire descent without using her poles. Upon reaching the bottom she continues to coast to a stop. How much kinetic energy will she have at the bottom of the hill?

Answers

Answer:

She will have kinetic energy at the bottom of the hill=45700 J

Explanation:

We are given that

Mass, m=60 kg

Speed, v=10 m/s

Height, h=150 m

Length of slope, d=650 m

Frictional force, f=70 N

We have to find the kinetic energy she will have at the bottom of the hill.

Kinetic energy  at the bottom of the hill

=Initial kinetic energy+ mgh-fd

Substitute the values

Kinetic energy  at the bottom of the hill

=[tex]\frac{1}{2}(60)(10)^2+60\times 9.8\times 150-70\times 650[/tex]

=[tex]45700J[/tex]

Hence, she will have kinetic energy at the bottom of the hill=45700 J

Problem 31:
The parallel circuit depicts three resistors connected to a voltage source.
The voltage source (AVtot) is a 110.-V source and the resistor values are
15.4 QR1), 21.9 D (R2) and 11.7 Q (R3).
b. Determine the current in each branch resistor.
c. Determine the total current in the circuit.

Answers

Answer:

Bi. Current in 15.4 Ω (R₁) is 7.14 A.

Bii. Current in 21.9 Ω (R₂) is 5.02 A.

Biii. Current in 11.7 Ω (R₃) is 9.40 A.

C. Total current in the circuit is 21.56 A.

Explanation:

Bi. Determination of the current in 15.4 Ω (R₁)

Voltage (V) = 110 V

Resistance (R₁) = 15.4 Ω

Current (I₁) =?

V = I₁R₁

110 = I₁ × 15.4

Divide both side by 15.4

I₁ = 110 / 15.4

I₁ = 7.14 A

Therefore, the current in 15.4 Ω (R₁) is 7.14 A.

Bii. Determination of the current in 21.9 Ω (R₂)

Voltage (V) = 110 V

Resistance (R₂) = 21.9 Ω

Current (I₂) =?

V = I₂R₂

110 = I₂ × 21.9

Divide both side by 21.9

I₂ = 110 / 21.9

I₂ = 5.02 A

Therefore, the current in 21.9 Ω (R₂) is 5.02 A

Biii. Determination of the current in 11.7 Ω (R₃)

Voltage (V) = 110 V

Resistance (R₃) = 11.7 Ω

Current (I₃) =?

V = I₃R₃

110 = I₃ × 11.7

Divide both side by 11.7

I₃ = 110 / 11.7

I₃ = 9.40 A

Therefore, the current in 11.7 Ω (R₃) is 9.40 A.

C. Determination of the total current.

Current 1 (I₁) = 7.14 A

Current 2 (I₂) = 5.02 A

Current 3 (I₃) = 9.40 A

Total current (Iₜ) =?

Iₜ = I₁ + I₂ + I₃

Iₜ = 7.14 + 5.02 + 9.40

Iₜ = 21.56 A

Therefore, the total current in the circuit is 21.56 A

An obect is placed 20cm from a convex mirror of focal length 12cm. where does the image form?

Answers

Answer:

7.5 cm behind the mirror

Explanation:

Applying,

Using the real is positive convection: All real distance from the mirror are positive

1/f = 1/v+1/u................. Equation 1

Where f = focal length of the mirror, v = image distance, u = object distance

From the question,

f = -12 cm, u = 20 cm

substitute these value into equation 1

1/(-12) = (1/20)+1/v

(-1/12)-(1/20) = 1/v

1/v = (-5-3)/60

1/v = -8/60

v = -60/8

v = -7.5 cm

Hence the image is formed 7.5 cm behind the mirror.

HELP

Answers

Answer:

Evaporation

Explanation:

Erosion is a natural process, but human activity can make it happen more quickly. Human activity altering the vegetation of an area is perhaps the biggest human factor contributing to erosion. Trees and plants hold soil in place.

Factor that contributes the most to the process of water erosion is Evaporation. The correct option is A.

What is evaporation?

Evaporation is the phenomenon of converting the liquid into gas phase by the addition of heat energy.

Erosion is also a natural phenomenon. Trees and plants hold soil in place and prevents the soil erosion. Just like that, the water erosion happens when more than natural evaporation happens due to increased heat by various factors.

Thus, Evaporation contributes the most to the process of water erosion. The correct option is A.

The index of refraction

What is the index of refraction?

The index of refraction tells us how much slower or faster light travels from one medium to another.

What is a medium? ⇒ the substance that light passes through

The formula to find the refractive index of a substance is the following:

[tex]n=\dfrac{c}{v}[/tex]

[tex]c[/tex] = the speed of light in a vacuum ([tex]3.00*10^8[/tex] m/s)[tex]v[/tex] = the speed of light in the medium

Explanation:

Given that,

The radius of the circular orbit, r = 42250 km

Time taken to revolve around the Earth, t = 24 hours

We need to find the speed of the satellite. We know that, speed of an object is equal to total distance traveled divided by the time taken. So,

[tex]v=\dfrac{2\pi r}{T}[/tex]

Put all the values,

[tex]v=\dfrac{2\pi \times 42250}{24}\\\\v=11061.02\ km/h[/tex]

So, the speed of the satellite is equal to 11061.02 km/h.
