in addition to power output light bulbs should also be labelled with the rate at which they emit visible light ​

Physics
1 answer:
NNADVOKAT [17]3 years ago
8 0

Answer:

While the energy label tells you about the energy performance of the light bulb you have bought, it does not say anything about its impact on the environment.  You will find out a little more by checking whether the bulb carries an ecolabel (a blue and green flower with star-shaped petals).

This European label guarantees products that have less of an impact on the environment and which are safe and reliable to use.  N.B.: This labelling is voluntary, which means that the product fulfils the ecological criteria set but is not necessarily the most environmentally friendly on the market (other products that do not carry the label may be equally or even more environmentally friendly).

Delicious77 [7]

Answer:

The answer is "Speed".

Explanation:

In the question, the Speed is the correct answer because it can be viewed as its rate from, which a length is covered via an object. It is also divided by time into other components of distance. Its SI unit of speed seems to be the meter/second, but still, the kilometer/hour or, in the Us UK, miles per hour is the most basic fundamental of speed in everyday use.

a current of 5 ampere is passed for 2 hours in an electric iron having a resistance of 100 ohms calculate the heat produced
Alina [70]

Answer:

\boxed{\sf Heat \ produced \ (H) = 5 \ kWh}

Given:

Resistance (R) = 100 Ω

Current (I) = 5 A

Time (t) = 2 hours

To Find:

Heat developed (H) in the electric iron

Explanation:

Formula:

\boxed{ \bold{ \sf H = I^2Rt}}

Substituting values of I, R & t in the equation:

\sf \implies H =  {5}^{2}  \times 100 \times 2 \\  \\ \sf \implies H = 25 \times 100 \times 2 \\  \\  \sf \implies H = 5000  \\  \\ \sf \implies H = 5 \: kWh

\therefore

Heat developed (H) in the electric iron = 15 kWh

An atom with an imbalance of electrons to protons is
alexdok [17]
<h2>Answer: Ion </h2>

An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons. </u>

To understand it better:

An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.

In this sense, there are two types of ions:

-Anions: ions negatively charged, by the gain of electrons in the atom.

-Cations: ions positively charged, by the loss of electrons in the atom.
