How do tests with crash dummies, seat belts, and air bags illustrate newton’s First law of motion
Answer:
Newton law of inertia.
Explanation:
Newton first law states that if any object is in the motion or is in the state of rest then it will remain in that state till the external force is applied on that object. Inertia is the main reason of having seat belts and air bags in the car.
In this case, when seat belt trapped into the passenger than passenger experience same state of motion as car has.
When the car experience any kind of the collision then the car will stop abruptly. In this case seat belt and air bag will help in stopping the motion of passenger in the forward direction.
Therefore Newton's law of inertia is illustrated in test with seat belts, crash dummies, and air bags.

A ball is dropped and falls with an acceleration of 9.8 m/s2 downward. It hits the ground with a velocity of 49 m/s downward. How long did it take the ball to fall to the ground?
It would take the ball 5 seconds to fall to the ground.
Given the following data:
Acceleration = 9.8 [tex]m/s^2[/tex]Final velocity = 49 m/s.Initial velocity = 0 m/s (since the ball is starting from rest).To find how long (time) it took the ball to fall to the ground, we would use the first equation of motion;
Mathematically, the first equation of motion is calculated by using the formula;
[tex]V = U + at[/tex]
Where:
A is the acceleration. V is the final velocity. U is the initial velocity. t is the time measured in seconds.Substituting the given parameters into the formula, we have;
[tex]49 = 0 + 9.8t\\\\49 = 9.8t\\\\t = \frac{49}{9.8}[/tex]
Time, t = 5 seconds.

How does nitrogen from the air get into the bodies of plants and animals?
Nitrogen is fixed from the atmosphere into a usable form for plants by nitrogen-fixing bacteria, which convert N₂ into nitrates. Plants absorb these nitrates, which are then passed on to animals when they consume the plants. Soil bacteria play a key role in recycling nitrogen back into the atmosphere.
Explanation:Nitrogen Fixation and the Nitrogen CycleNitrogen from the air gets into the bodies of plants and animals primarily through a process called nitrogen fixation. This is carried out by special bacteria known as nitrogen-fixing bacteria. These bacteria convert nitrogen gas (N₂), which plants cannot use, into a form that plants can absorb and utilize. The most common form is nitrate (NO₃⁻), which plants take in through their roots. Animals then obtain nitrogen by consuming plants or other animals that have eaten plants. After the nitrogen has been utilized by living organisms, bacteria in the soil convert waste products and dead organisms back into nitrogen gas through a process called denitrification, completing the nitrogen cycle.
There are different types of nitrogen-fixing bacteria, some live freely in the soil, while others form symbiotic relationships with the roots of certain plants, such as legumes. Cyanobacteria and Rhizobium are notable members of the nitrogen-fixing bacteria group. Additionally, lightning can also transform atmospheric nitrogen into nitrate, providing another source for the nitrogen cycle.

What is the Coriolis effect?The Coriolis Effect can be described as an apparent effect formed by a rotating frame of reference. The effect takes place when an object moves along a straight path. The Earth which rotates at a fixed speed is the moving frame of reference.
Coriolis force is defined as the perpendicular to the object’s axis. The Coriolis force acts north-south as the Earth spins on its axis from west to east and the Coriolis force is zero at the Equator.
Coriolis force appears to deflect the objects and kind of invisible force. The Coriolis force is calculated by the rate of rotation and mass of the object.
The Coriolis effect generates wind patterns that travel to the east toward the equator and to the west toward the poles near the earth’s surface. These prevailing wind patterns are accountable for moving clouds around the globe and creating weather in different regions.

What is the purpose of the three R’s of resource management?
The three R's of resource management stand for reduce, reuse, and recycle. Together, they form a cornerstone philosophy for managing our resources sustainably.
The first R, reduce, emphasizes the importance of cutting back on the amount of waste we produce and reducing our consumption patterns. Reuse encourages us to repurpose items instead of discarding them, thus extending their life cycle and diminishing the need to consume new resources. Lastly, recycle involves processing used materials to create new products, which conserves raw materials and reduces the need for energy-intensive manufacturing processes.
The purpose of the three R's is to: 1. Distribute resources fairly among people, ensuring that resources do not become excessively depleted by overconsumption. 2. Conserve resources so that they are available for future generations without running the risk of depletion. 3. Use resources in ways that do not harm ecosystems, maintaining the delicate balance of our environment.
Effectively applying these principles contributes to the sustainability of rural and regional communities, and ensures that resources are used wisely. This approach helps to transition society from consumerism to conservation, a concept proposed by environmental advocates like the Pollution Probe and governmental advisory boards such as Canada's Science Council in the early 1970s.

a small 24 kilogram canoe is floating downriver at a speed of 3 m/s.what is the canoe's kinetic energy .
{~please help fast ~}
That all depends who's measuring it.
... If one Physics student is standing on the riverbank, watching the canoe float by, he will measure the canoe's kinetic energy and say it's 108 Joules.
... If another Physics student is sitting on another boat, floating on the same river and watching the same canoe, she will say that the canoe has zero kinetic energy.
Both of them are correct.
Explanation :
Mass of the canoe, m = 24 kg
Speed of the canoe, v = 3 m/s
Kinetic energy is said to be possessed due to the motion of the object and it is given as :
[tex]E_k=\dfrac{1}{2}mv^2[/tex]
v is the velocity of the canoe.
[tex]E_k=\dfrac{1}{2}\times 24\ kg\times (3\ m/s)^2[/tex]
[tex]E_k=108\ J[/tex]
So, the kinetic energy of the canoe is 108 J
Hence, this is the required solution.
Which of the following is likely to contribute to geological events that take place on Earth?
Crust undergoing convective currents
Crust being of uniform thickness throughout
Crust being a single layer that surrounds Earth
Crust sitting on top of molten rock of the mantle
Answer:
Crust sitting on top of molten rock of the mantle
Explanation:
Earth's crust is the geological name for what we usually call the surface of the planet, and it is immediately above the molten rock of the mantle, the next layer of the planet.
The crust happens to be fragmented in large pieces or tectonic plates, that can be seen as "drifting" on the mantle's molten rock, also known as magma.
In some areas tectonic plates are drifting away, allowing magma to reach the surface (volcanoes for example), or the seabed (forming mid-oceans crests).
In other areas tectonic plates are crashing each other, causing earthquakes, tidal waves, mountain formation and other relevant geological events.

A machine shovel moves dirt at the rate of 1,100 pounds of dirt 1 foot in 1 second. How many horsepower is this?
The machine shovel that moves 1,100 pounds of dirt 1 foot in 1 second exhibits 2 horsepower, based on the calculation that compares the work done in foot-pounds per second to the standard definition of one horsepower as 550 foot-pounds per second.
To calculate the amount of horsepower exhibited by a shovel machine moving 1,100 pounds of dirt 1 foot in 1 second, we can use the definition of horsepower. By definition, one horsepower is equal to 550 foot-pounds per second. The machine does 1,100 foot-pounds of work per second (since it moves 1,100 pounds over 1 foot in 1 second).
Now, we calculate the horsepower
Power (hp) = Work (foot-pounds per second) / 550
Power (hp) = 1,100 foot-pounds per second / 550
Power (hp) = 2 hp
Thus, the machine shovel operates at 2 horsepower.
