Answer:

Effusive eruptions occur when hot, (1200oC) runny basalt magmas reach the surface. Dissolved gases escape easily as the magma erupts, forming lava that flows downhill quite easily. Effusive eruptions build up gently-sloping Shield Volcanoes like Hawaii.

Answer:

the cost of running the bulbs is 11.25p

Explanation:

Given;

cost of running 1 kwh = 10 p

power of filament bulb, P = 60 W

power of the CFL bulb, P = 15 W

time of power consumption, t = 15 hours

Total Energy consumed;

E = (60W + 15W) x 15 hours

E = (75)(15)

E = 1125 Wh

E = 1.125 kWh

Cost of 1.125 kWh  =   1.125 x 10p

                               = 11.25p

Therefore, the cost of running the bulbs is 11.25p

Zero, neutral means no extra electrons.

Answer:

[tex]s_2=-806m[/tex]

Explanation:

From the question we are told that

Velocity 1 [tex]v=1.34m/s \angle west[/tex]

Distance  [tex]d=6.44km=>6440m[/tex]

Velocity 2  [tex]v_3=2.68m/s[/tex]

Velocity 3  [tex]v_3=0.447m/s \angle east[/tex]

Generally the equation for VT is mathematically given by

[tex]VT=v_1t_1 +V_2t_2[/tex]

[tex]VT=2.68(2400)-0.447t_2[/tex]

[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]

[tex]t_2=1804s[/tex]

Therefore

[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]

[tex]s_2=-806m[/tex]

Answer:

1,500 km

Explanation:

300 km/h

300 kilometers PER HOUR

So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.

300 * 5 = 1,500

The train moves at 1,500 km in 5 hours.

Explanation:

1. Determination of the mass of gasoline

Density of gasoline = 0.7 Kg/L

Volume of gasoline = 15 L

Mass of gasoline =?

The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance can be expressed as:

Density = mass / volume

With the above formula, we can obtain the mass of the gasoline as follow:

Density of gasoline = 0.7 Kg/L

Volume of gasoline = 15 L

Mass of gasoline =?

Density = mass / volume

0.7 = Mass of gasoline / 15

Cross multiply

Mass of gasoline = 0.7 × 15

Mass of gasoline = 10.5 Kg

2. Density has various units some are listed below:

I. Kilogram per litre (Kg/L)

II. Kilogram per cubic metre (Kg/m³)

III. Milligram per millilitre (mg/mL)

IV. Gram per millilitre (g/mL)

V. Gram per cubic centimetre (g/cm³)

Considering the options given in the question above, it is evident that second per gram (s/g) is not a unit of density because density is mass per unit volume.

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.

Explanation:

Answer:

a) [tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex], b) [tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex], c) [tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]

Explanation:

a) Translational kinetic energy ([tex]E_{k}[/tex]), measured in joules, is represented by the following expression:

[tex]E_{k} = \frac{1}{2}\cdot m \cdot v^{2}[/tex] (1)

Where:

[tex]m[/tex] - Mass, measured in kilograms.

[tex]v[/tex] - Velocity, measured in meters per second.

Now we clear the mass within the formula:

[tex]E_{k} = \frac{1}{2}\cdot m\cdot v^{2}[/tex]

[tex]2\cdot E_{k} = m\cdot v^{2}[/tex]

[tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex]

b) Now we clear the velocity squared:

[tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex]

c) Now we clear the velocity:

[tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]

Explanation:

Given parameters:

Number of moles of H₂O = 2moles

Unknown:

Mass of  H₂O = ?

Solution:

To solve this problem, use the expression below:

   Mass of  H₂O = number of moles x molar mass

Molar mass of  H₂O = 2(1) + 16  = 18g/mol

  Mass of  H₂O = 2 x 18  = 36g

Explanation:

Answer:

1600 years half life

3200/1600 is 2 half lifes

first half life takes the sample to 1/2 it's original amount and the second takes it to 1/4 of it's original amount

so 1/4*7gm is 1.75gm

Explanation:

Secretary of Homeland Security was not a department in Washington's first cabinet. So, the correct option is B.

George Washington created the nation's first cabinet, made up of the president's most trusted advisers, where advisers advise the president on laws, taxes, foreign affairs, defense, and other important issues on how to govern the United States.

George Washington's first cabinet was consists of attorney and postmaster generals and secretaries of state, treasury, and war.

Explanation:

Entropy is the measurement of disorder in a system. The greater the entropy the more disorder/mess there is. Options A B and C all have organized systems so D is the only one with the least orderly scenario

Scattered over the ground represents the highest entropy of a deck of playing cards.

Entropy is a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
