Explanation

pH is directly proportional to the oxygen-carrying capacity

Meaning that as pH increases, the ability of blood to carry oxygen also increases. 

Explanation

Mass is converted into energy (or vice versa), following Einstein’s equation: E=mc^2

Explanation

Never connect ohm meter on live circuits to avoid electric shock or damage.

Explanation

A NOT gate, also known as an inverter.

It is a digital logic gate that negates the input signal.

If the input is "1", the output will be "0".

If the input is "0", the output will be "1".

The truth table for a NOT gate is:

Input | Output

-----|------

0 | 1

1 | 0

Explanation

A spring balance is a device used to measure the weight of an object.

It consists of a spring that is stretched or compressed by the weight of the object, and a pointer or dial that indicates the weight.

Explanation

The vertical component of the force is:

Vertical component = Force × sin(angle)

= 15 N × sin(60°)

= 15 N × 0.866

= 13 N

So, the vertical component of the 15 N force at an angle of 60° is approximately 13 N.

Explanation

• Nuclear energy is a method of harnessing the energy released from the splitting of atomic nuclei (a process called nuclear fission) to generate electricity.
• The main purpose of nuclear energy is to provide a clean and reliable alternative source of energy, reducing dependence on fossil fuels and mitigating climate change.

Explanation

The law of conservation of energy is based on the principle of Bernoulli's theorem.

Bernoulli's theorem states that in a steady flow of an incompressible, frictionless fluid, the total mechanical energy (sum of potential energy, kinetic energy, and pressure energy) per unit mass of the fluid remains constant along a streamline.

This means that the total energy of the fluid is conserved as long as no external forces are acting on it, such as friction or heat transfer.

Explanation

To find the energy stored in a capacitor, we use the formula:

E=1/2​CV^2

Where:

• $\mathrm{<br>}$

• $V=100\text{V}$

Calculation:

$$E = frac{1}{2} times 4 times 10^{-6} times (100)^2$$E=1/2​×4×10^−6×10000
E=2×10^−6×10000

$$=0.02\text{J}$$

Explanation

• In a parallel circuit, if one bulb blows, the other bulb will remain the same.
• This is because each bulb in a parallel circuit has its own independent path to the power source.
• The failure of one bulb does not affect the current flowing through the other bulb's path.
