Corrosive substances are rarely harmful to human skin.   This statement is <em>False.</em>  Corrosive substances are ALMOST ALWAYS harmful to the skin.

Most problems addressed by the technological design process have only one solution.  This statement is also <em>False.</em>  There is more than one way to skin a cat.

Answer:

False. Corrosive substances are harmful to human skin.

False. Most problems addressed by the technological design process have more than one solution.

Explanation:

Corrosive substances have a high tendency to damage other substances  which it comes in contact with. They could either by concentrated acid or a base which are very harmful to human skin. These have the capacity to destroy, disfigure or burn any part of human body that comes in contact with the substance.

Technological design is the process of developing appropriate knowledge into physical solutions to solve various problems. In technology, there are always more than a solution to a problem, as there are different ways to solve technological problems.

Thus, the answers to the two questions is false.

Photovoltaic cells: a) have become more economical to produce and use over the past 25 years. b) are the most efficient means of
Yanka [14]

Photovoltaic cells are the most efficient means of converting solar energy to electricity. Option b is correct.

<h3>What is a cell?</h3>

A cell is a voltage and current-producing device that consists of a single anode and cathode separated by an electrolyte.

One or more cells can make up a battery. One cell, for example, is one AA battery.

Light intensity on a solar cell is often measured in "suns," with one sun roughly equivalent to 1 kW/m².

Concentrated sunlight improves the ratio of current generated while the device is lighted vs when it is dark, hence enhancing output voltage and efficiency.

Photovoltaic cells are the most efficient means of converting solar energy to electricity.

Hence, option b is correct.

To learn more about the cell refer to:

Adding or removing thermal energy to or from a substance does not always cause its temperature
julia-pushkina [17]
Change in thermal energy not always cause it's temperature change. It is the situation when water reaches either at 0 C or 100 C then thermal energy doesn't cause change in temperature instead it changes the state of matter.

In short, Your Answer would be "True"

Hope this helps!

IP The x and y components of a vector r⃗ are rx = 16 m and ry = -8.5 m , respectively
fiasKO [112]

as it is given that

r_x = 16 m

r_y = -8.5 m

now we will have

\vec r = 16 \hat i - 8.5 \hat j

now the magnitude of this vector is given as

|r| = \sqrt{16^2 + 8.5^2}

|r| = 18 m

now to find the direction we can use

tan\theta = \frac{r_y}{r_x}

tan\theta = \frac{-8.5}{16}

\theta = tan^{-1}(-0.53)

\theta = - 28^0
