A. Knowledge of local geology helps in the design of a dam for a
reservoir.
B. A new type of telescope helps people learn new facts about
comets.
C. A new type of computer makes weather forecasts more accurate.
D. Satellite imaging allows people to map the extent of forest fires.
An event that is an example of science helping to engineer is Knowledge of local geology helps in the design of a dam for a reservoir. Thus the correct option is A.
What is Science?Science is the systematic, evidence-based scientific investigation and implementation of knowledge and perception of the natural and social world which provides information about various things to an individual.
Combining math and science to tackle issues usually defines the functions of engineering. Engineers are the ones who translate advances in science into practical applications.
The individual who studies Science is referred to as a Scientist whereas those studies about engineering are referred to as Engineers.
When the design of a dam for a reservoir is created Science helps engineering by providing information and knowledge about Local Geology to help them.
Therefore, option A is appropriate.

Personal water filters solve the problem of having access to safe drinking water anywhere. They are available and affordable. The materials used to make them are durable. They protect, rather than harm, users. Overall, the benefits outweigh the risks.
Explanation:
i just know its right because its the sample response :D
The personal water filter meets the following requirements: It cleans tap water for domestic use, is reasonably priced, and is easy to transport.
What is water filter?A water filter reduces water contamination through the use of a thin physical barrier, a chemical reaction, or a biological reaction to remove contaminants.
Conditions were satisfied in the example scenario:
Functionality: The personal water filter is capable of effectively removing germs and other pollutants from water.The filter is portable and convenient to use while traveling or camping because it is small and light.Affordability: The filter is a reasonable solution for those on a tight budget, costing around $20 or so.Durability: The filter can resist the wear and tear of continuous use thanks to its durable plastic design.Unmet requirements:
Heavy Metal Removal: In locations where water sources are tainted with such substances, the filter's inability to remove heavy metals from water raises some questions.In locations where water supplies are contaminated with these bacteria, the filter's ineffectiveness at removing viruses may be a problem.In regions where only saltwater is accessible, the filter's inability to remove salt from the water could be a problem.Longevity: The filter is sturdy, however depending on usage, it might not last as long as other filtering systems and might need to be changed rather frequently.Thus, these are the criteria it does or does not meet.

A series RLC circuit consists of a 100 W resistor, a 0.15 H inductor, and a 30 µF capacitor. It is attached to a 120 V/60 Hz power line (the voltage 120V is the root mean square value). What are
a. The emf εrms
b. The phase angle ϕ
c. The average power loss
(a) The root mean square value of current in the circuit is 1.14 A.
(b) The phase angle ϕ of the circuit is 17.7⁰.
(c) The average power loss in the circuit is 136.4 W.
Capacitive and inductive reactance of the RLC circuitThe capacitive and inductive reactance of the series RLC circuit is calculated as follows;
Xc = 1/ωC
[tex]X_c = \frac{1}{2\pi f C} = \frac{1}{2\pi (60)(30 \times 10^{-6})} = 88.42 \ ohms[/tex]
Xl = ωL
Xl = 2πfL
Xl = 2π(60)(0.15)
Xl = 56.55 ohms
Impedance of the circuitThe impedance of the circuit is calculated as follows;
[tex]Z = \sqrt{R^2 + (X_c - X_l)^2} \\\\Z = \sqrt{100^2 + (88.42 -56.55)^2} \\\\Z = 104.96 \ ohms[/tex]
Rms current of the circuit[tex]I_{rms} Z = V_{rms}\\\\I_{rms} = \frac{V_{rms}}{Z} \\\\I_{rms}= \frac{120}{104.96} \\\\I_{rms}= 1.14 \ A[/tex]
Phase angleThe phase angle of the circuit is calcuated as follows;
[tex]tan \phi = \frac{X_c - X_l}{R} \\\\tan\phi = \frac{88.42 - 56.55}{100} \\\\tan\phi = 0.3187\\\\\phi = tan^{-1}(0.3187) \\\\\phi = 17.7 \ ^0[/tex]
Average power loss in the circuitThe average power loss in the circuit is calculated as follows;
[tex]P = I_{rms}^2 Z\\\\P = (1.14)^2 (104.96)\\\\P = 136.4 \ W[/tex]

Shops can mix refrigerants
Answer:
False
Explanation:
The statement "Shops can mix refrigerants" is false.
What are refrigerants?Refrigerants are the chemicals that are used in the refrigerator's cycle of the air conditioner. They are fluid. Examples of refrigerants are CFC, HCFC, FC, ammonia, etc.
They are changed to form a phase of liquid to gas and gas to liquid. They are their transition stages. There are four types of refrigerants. They are Evaporative Cooling, Mechanical-Compression Refrigeration Systems, absorption, and thermoelectric.
Inadequate system pressures and temperatures can be brought on by mixed refrigerants. This may lead to inadequate cooling of the compressor, potential compressor damage, inadequate cooling, and metering device malfunction.
Thus, the statement is false regarding shops can mix refrigerants.
