The ability of the ground water to pass through the pore spaces in the rock is described as the rock's permeability. Permeable layers of rock that store and transport water are called aquifers.

One example is that when their food catches fire in a cooking pot or pan, it is advisable to smother the fire by covering the fire with a blanket rather than douse the fire with water. DOeing the later will only aggravate the fire. Knowledge of basic science dictates that oil and water are immiscible liquids the oil will continue to burn even as the water is poured into the oil. More so, as the water violently evaporates due to the heat, it spreads the burning oil and hence spreads the fire.

- Gas central heating is used for 5 days, using 102 kWh of energy. If 1 kWh of gas costs 7p, calculate the cost of using the cen

melamori03 [73]

Answer:

Explanation:

Given that,

Gas central heating was used for 5days

At a rate of 102kWh of energy

Then, 1 kWh = 7p

So,

The total time is 5days

t = 5days

1 day = 24hours

Then, t = 5days = 5 × 24 = 120hours

Given 102kWh, then, they consumers 102 kW in one hour, then, for the 120hours,

The total energy used is 102 × 24

Then, total energy = 2448 kWh

So, 1 kWh = 7p,

Then, 2448 kWh = 7 × 2448

2448 kWh = 17,136 p.

So, the cost of the using central heat is 17,136 p

What is the wavelength of a radio photon from an "am" radio station that broadcasts at 1080 kilohertz?

asambeis [7]

<span>208.3 meters The product of the wavelength multiplied by the frequency will equal the speed of light which is 299792458 m/s. Simple algebra will tell you that you can divide the speed of light by the frequency to get the wavelength. So 224997958 m/s / 1080000 1/s = 208.3314426 m Rounding to 4 significant digits gives you 208.3 meters.</span>
