Cords on appliances should be kept straight and free of knots, kinks, and tangles to prevent breaks.

Bending, twisting, or knotting electrical cords can cause the wires inside the cord to become damaged or broken, which can lead to a short circuit or electrical shock hazard. A damaged or broken cord can also cause the appliance to malfunction or stop working altogether. Therefore, it is important to keep cords straight and avoid creating any sharp bends or kinks that could stress the cord and cause it to break.

Volts and currents are electrical properties related to the flow of electricity, while loads refer to the amount of electrical power being used by an appliance. While knots, kinks, and tangles in cords can indirectly affect volts, currents, and loads, the primary concern is the physical integrity of the cord and preventing breaks.

A sustainable energy source is an energy source that can be used without depleting it, and is renewable over an extended period of time.

In addition, sustainable energy sources should also be environmentally friendly. Below are three features that would make an energy source sustainable:Renewability: For an energy source to be sustainable, it must be renewable. Renewable energy is an energy source that can be used over and over again without being depleted. Sunlight, wind, water, and biomass are all examples of renewable energy sources. On the other hand, fossil fuels such as coal, oil, and natural gas are non-renewable energy sources. They are finite resources that will eventually run out. Therefore, sustainable energy sources must be renewable.Durability: Sustainable energy sources must be durable. Durable sources of energy can produce energy for long periods without needing repair or replacement. In contrast, non-renewable sources of energy such as fossil fuels are finite resources that can be depleted, and once depleted, they cannot be replenished again. Hence, sustainable energy sources must be durable and provide energy over a long period of time.Environmentally friendly: Sustainable energy sources should be environmentally friendly. This means they should not produce any harmful emissions or pollutants that may harm the environment. Unlike non-renewable sources of energy, renewable energy sources have no adverse impact on the environment. The use of renewable energy sources reduces carbon emissions and decreases the dependence on fossil fuels, which are harmful to the environment.In summary, a sustainable energy source must be renewable, durable, and environmentally friendly. These three features ensure that the energy source can be used without depleting it, is renewable over an extended period of time, and does not harm the environment.

The big ben clock tower in London has clocks on all four sides. If each clock has a minute hand that is 11.5 feet in length, how far does the tip of each hand travel in 52 minutes?

The distance traveled by the tip of the minute hand of the clock would be 62.59 ft

Explanation:

Let us assume the shape of the clock is circular.

the minute hand is equal to the radius = 11.5 ft

Diameter = radius x 2

Diameter = 11.5 x 2 = 23 ft

The distance traveled by the tip of the minute hand can be calculated thus;

the fraction of the circumference traveled by the minute hand would be;

52/60 = 0.8667

Circumference of the clock would be;

C = pi x d

where C is the circumference

pi is a constant

d is the diameter

C = 3.14 x 23

C = 72.22 ft

Therefore the fraction of the circumference covered by the minute hand would be;

72.22 ft x 0.8667 = 62.59 ft

Therefore the distance traveled by the tip of the minute hand of the clock would be 62.59 ft
