what substance might impact the formation of volcanic rock?

marking brainliest!

Answers

Answer 1

Answer:

Magma is less dense than the surrounding rock which causes it to rise. When magma reaches the surface it is then called lava and the eruptions of lava and ash produce volcanoes. The lava that reaches the Earth's surface will harden and become igneous rock.

Answers

Answer:

a.45N

b.52.2N

c.36.45N

Explanation:

note:these answers are based on the fact that the acceleration due to gravity is 10m/s²

*.first of all the tension (T)in the cable is equivalent to the mass(m) of object multiplied by the sum of the opposite and parallel accelerations of the gravity and the elevator respectively.ie. g and a

now that being said mathematically the formula for tension in the cable is given by

T=m(g+a).

a).now for this situation the elevator is stationary,thus has not accelerated,

so a=0

then T=mg; where m=4.5kg g=10ms-²

therefore, T=4.5*10=45N.

b).here the elevator accelerated up, so a is positive.ie.+a

hence T=4.5(10+1.6)=52.2N.

c).here also the elevator accelerated down, so a is negative. is.-a

hence T=4.5(10-1.9)=36.25N.

Explanation:

1. Coal is not a renewable source and take along time for it to form so it will soon run out

2. Burning coal releases fossil fums into the air affecting the ozone layer but using solar power dose not release anything into the air

Answer:

Renewable energy works as clean sources of energy, and don't make as much of a detrimental impact on the environment as non-renewable energy. Air pollutants are a product of some non-renewable sources, and it negatively affects the atmosphere, humans, animals, and oceans.

Also, renewable sources won't run out, unlike other sources, as they are finite and will not last forever.

The temperature inside a Carnot refrigerator placed in a kitchen at 22 degree Celcius is 2 degree Celcius. The heat extracted from the refrigerator is 89 MJ/h. What power is needed to operate this refrigerator?

Answers

Answer: 1.79 kW

Explanation:

Given

The temperature of the refrigerator is [tex]T_L=2^{\circ}C\approx 275\ K[/tex]

The temperature of the kitchen is [tex]T_H=22^{\circ}C[/tex]

COP of the refrigerator is

[tex]COP=\dfrac{T_L}{T_H-T_L}=\dfrac{\text{Desired effect}}{\text{Power}}\\\\\Rightarrow COP=\dfrac{275}{22-2}=\dfrac{89}{P}\\\\\Rightarrow P=\dfrac{20}{275}\times 89=6.47\ MJ/h\ \text{or}\ 1.79\ kW[/tex]

Answers

Answer:1.) 2 seconds

2.) 4.5 hertz

3.) it will become one third is original value

4.)5.9 seconds

5.)0.87 meters

Explanation:

1. The time period of wave is 0.125 second

2. The frequency of a wave in the second rope is 1.5 hertz.

3. The frequency will become one third of its original value.

4. the time taken by sound of a clap of thunder to travel 2 kilometers is 5.9 seconds.

5. The wavelength of note is 0.87 meter

1. Time period [tex]=\frac{1}{frequency} =\frac{1}{8} =0.125second[/tex]

2. Since both rope are identical. Therefore, both rope have same frequency.

Thus,  The frequency of a wave in the second rope is 1.5 hertz.

3. In relation between wavelength and frequency, wavelength is inversely proportional to frequency.

If the wavelength of a wave in a particular medium is tripled , then the frequency of the wave will become one third of its original value.

4. The time taken by sound of a clap of thunder,

                                    [tex]=\frac{2000}{340}=5.9seconds[/tex]

5. Wavelength is the ratio of speed to the frequency.

If the maximum moment of force on a door is 10 Nm by an applied force of 2.25 N, then the distance of handle

Answers

Answer:

d = 4.44 m

Explanation:

Given that,

The moment of force on a door = 10 N-m

The applied force, F = 2.25 N

We need to find the distance of the handle. The moment of force is given by :

[tex]\tau=F\times r[/tex]

Where

r is the distance of the handle.

[tex]r=\dfrac{\tau}{F}\\\\r=\dfrac{10}{2.25}\\\\r=4.44\ m[/tex]

So, the required distance is equal to 4.44 m.

what is required to cause a body of mass 500g to accelerate uniformly from rest across a smooth horizontal surface so that it will cover a distance of 20 tometre in 4 seconds .​

Answers

A constant force of 1.25N

Explanation:

This is a kinematics problem.

First find acceleration,

then use F = ma to find force.

Given:

mass = .5kg

delta x = 20m

t = 4s

a = ?

Friction = 0

From the kinematics equations:

delta x = Vi + (1/2)at^2

Plug in terms that are given:

20m = 0 + (1/2)a(4^2)

(2*20m)/(16s^2) = a

40m/(16s^2)= 2.5m/s^2

Now use F = ma to find force exerted on object.

F = (0.5kg)*(2.5m/s^2)

F = 1.25N

pressure difference

Answers

Answer:

101201.2 Pascal.

Explanation:

Given that the difference h between the two liquid levels is 2.0 cm. The density of the liquid is 800 kg /m3.

Calculate the difference between the pressure of the gas and atmospheric

pressure.

The pressure of the gas can be calculated by using the formula

Pressure = density × acceleration due to gravity × height

Substitute all the parameters into the formula

Pressure = 800 × 2/100 × 9.8

Note that the height is converted to metre.

Pressure = 156.8 Pascal

pressure difference = 101358 - 156.8

Pressure difference = 101201.2 Pascal
