Explanation:
Motion is defined as a change in an object's position when compared to other objects around it. Mary Ann was watching a slug crawl across the driveway. She saw that a small rock was beside the slug when she first started watching it.
Since a slug moves so slowly, how does Mary Ann know that the slug is actually in motion?
A) She can tell the slug is moving because time has passed.
B) She can tell the slug is moving because she set her watch.
C) She can tell the slug is moving by never taking her eyes off of the slug.
D) She can tell the slug is moving by comparing the change in distance between the rock and the slug.
Answer:
Explanation:
Do it yourself bum
Mary Ann can tell the slug is moving by comparing the change in distance between the rock and the slug. Hence, the correct option is D.
Interpreting the motion of an object
Motion is defined as a change in position relative to a reference point. In this scenario, the rock acts as a reference point for Mary Ann.
If Mary Ann observes the distance between the slug and the rock changing over time (the slug getting further away from the rock), she can determine that the slug is moving even though it's slow.
Hence, the correct option is (D.)

Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm. How might using a model help Marty develop his design? A. A model could be used for automobile windshields. B. Airplane manufacturers could be sold models to use in their new planes. C. Marty could use a model to discover a new type of plastic for windshields. D. A model could be used to test his design in a lab.
D: A model could be used to test his design in a lab
Explanation:
Engineers use models to help them develop new or improved technologies. Models allow engineers to test a design to see how it will perform in the real world. So Marty can use a model to test his design in a lab, before it is used in real airplanes. This process will ensure that Marty's deign is both effective and safe.

The greater the force applied to an object, the _____ the change in speed or direction of the object.
A) equal
B) greater
C) lesser
D) slower
Option.B-Greater is the correct answer.
The more force exerted to an object, the more the object's speed or direction will change.
What is Newton second law of motion?An object accelerates whenever it increases its speed, decreases its speed, or changes direction.When an unbalanced force acts on an item, acceleration happens. The mass of the object and the net force acting on it both have an impact on an object's acceleration.The influence of force and mass on acceleration is described by "Newton's second law of motion."According to the law, an object's acceleration is equal to its mass divided by the net force acting on it.The second law of Newton demonstrates that force and acceleration are directly related.An object of a given mass will accelerate more quickly the more force is applied to it. For instance, when the force acting on an item is doubled, so is the acceleration.Mass and acceleration have a different relationship. An inverse relationship exists.When one variable rises in an inverted connection, the other variable falls.The less an object accelerates when a certain force is applied, the more mass it has. For instance, when an object's mass is doubled, the acceleration is reduced by half for a given force.To know more about Newton's second law of motion click here-

material fastened to a metal
backing plate?
A)Steel
B) Wood
C)Friction
D)Oily
D)The brake pad has a block of friction material fastened to a metal backing plate.
Explanation:
A brake pad backing plate is designed in such a manner that it resists rust and maintain the adhesive bond between the friction material and plate over its entire life. Also, a brake pad backing plate must maintain dimensional stability.The brake pad has to be constructed quite well since It is a crucial as well as critical component in a brake system. A block of friction material meets all these characteristics and thus preferred as a material in brake pads.Electromagnetic waves can carry more data at higher frequencies. Why would a scientist opt to transmit data at a lower frequency instead?
Answer:Transmitting data over low frequency electromagnetic waves can reach great distances before attenuation because are not easily interfered with by obstacles like high frequency waves are. This is because they can diffract over obstacles and pass around them with less shadowing.
A disadvantage of using electromagnetic waves to transmit data is interference. One cause of interference is the transmission ton over same frequency hence the necessity to regulate these waves through policies. Other causes of interference are due to weather or obstacles.
Analogue signal is the decoding of electromagnetic waves into electric pulses (of varying amplitudes) by a decoder and pass the electric circuit in the electronics. However, in digital signal, electromagnetic waves are converted to binary format (0s and 1s). Therefore, analogue signal is a continous signal while digital is discretely broken down into bits.
Digital signal have the advantage of analogue signal over the fact that they can carry loads of information. Analogue signal draws more power than digital signal hence the later is eco-friendly. Digital signals are less likely to be affected by noise unlike analogue signals.
One major application for analogue signals is their use is speakers and microphones. Nonetheless, contemporarily, there are emerging digital microphones and speakers. A popular example of application of digital signal is in the mobile communication industry. The shift from analogue to digital has been greatly revolutionalized communication

How do you keep the weight evenly distributed on a trailered boat?
A.Only store heavy items in the boat
B.Tie down any loose items or equipment in the boat
C.Avoid loading the boat with additional gear
D.Avoid tying down the boat to the trailer
The best way to keep the weight evenly distributed on a boat is to tie down any loose items or equipment in the boat.
By tying down loose items or equipment inside the boat, you ensure that the weight is evenly distributed and secured. This helps maintain balance and stability while the boat is being towed on a trailer.
It prevents the shifting of weight during transit, reducing the risk of imbalance and potential accidents.
It is important to secure all items to prevent them from moving around and potentially causing damage to the boat or affecting the trailer's stability.

When is liquid electrical tape a better choice than conventional electrical tape for covering exposed conductors?
Advantages of liquid electrical tape over conventional electrical tape for covering exposed conductors is given below.
Explanation:
Electrical tape and "regular" adhesive tape is that electrical tape is stretchy. This allows the tape to wrap around a wire junction and still grab the insulation to either side. This helps keep the tape in place.Where as Regular tape is likely to get stiff, lose adhesion, and slide away from the joint, leaving it exposed.The electrical tape is able to withstand much more heat and like the others said the adhesive is better and it can stretch 200 percent.Electrical tape is a suitable long-term or permanent solution in various applications.Heat-shrink sleeving, spiral wrap, flexible conduit, self-amalgamating tape, rubber sleeves, junction boxes, table ties/clips, grommets, cable markers, etc. are all better solutions for almost any given use of electrical tape other than to conventional electrical tape which has temporarily hold, bundle, insulate, or mark a cable.This kind of type is often used by electricians. It's typically made of slightly stretchy PVC vinyl, and is backed with a pressure sensitive rubber-type adhesive. It has good insulative properties, and is perfect for protecting wire splices and providing extra insulation on electrical cords. it's also available in a variety of other colors (like red, green, yellow, green, and white) that can be used for color-coding.Why is it important to cut all the way through an electrical wire on the first try?
Answer:
I always thought it was so that the older wire could not have a problem and have another electrician must come back and fix it.

What is the actual mechanical advantage (AMA) required by a machine to complete the work
You build a ramp to create the ideal mechanical advantage. What is the length of the ramp in feet?
Answer:
A) 180000 lbft
B) 6
C) 90 ft
Explanation:
work to be imputed is
Wi = F x d
= 12,000 lb x 15 ft
= 180000 lbft of work
Work you can produce is
Wa = F x d
= 2000 lb x 15 ft = 30000 lbft
Mechanical advantage that will be needed = Wi/Wa = 180000/30000
= 6
Lenght of ramp = 6 x 15 ft = 90 ft

You could be sued if you injure someone while rescuing them if...
1. your car's brakes failed
2. the accelerator in your car got stuck
3. they ran a red light and hit you
4. you collided with their car on purpose
You could be sued if you injure someone while rescuing them if 4. you collided with their car on purpose.
Let us discuss the various scenarios:
Your car’s brakes failed: If your car’s brakes failed and you injured someone while trying to rescue them, you could potentially be sued if it is proven that you knew about the brake failure and did not take appropriate action to fix it. This could be seen as negligence.
The accelerator in your car got stuck: Similar to the brake failure, if the accelerator in your car got stuck and caused an injury, you could potentially be sued if it is proven that you knew about the issue and did not take steps to fix it.
They ran a red light and hit you: If someone ran a red light and hit you while you were attempting to rescue them, it is less likely that you would be sued, as they were the one breaking the law. However, specific circumstances and local laws could affect this.
You collided with their car on purpose: If you intentionally collided with their car, causing injury, you could definitely be sued. Intentionally causing harm is generally not protected, even in rescue situations.
Thus, the correct option is 4.
