If vx = 3 meters/second and vy = 4 meters/second, what is the magnitude of the resultant velocity?
Answer
5m/s
Explanation:
Resultant is defined as the single velocity/forces that balances all other velocities/forces acting on a body. It is also defined as the vector sum of the vectors acting on a body.
Given two vectors in the x and y direction i.e Vx = 3m/s Vy = 4m/s
The formula of the resultant of both vectors will be;
R²= Vx² + Vy²
Where R is the resultant vector
R²= 3²+4²
R²=9+16
R²=25
R=√25
R=5m/s
Therefore, the magnitude of the resultant velocity is 5m/s

a stone is thrown down off a bridge with a veloctiy of 5.6m/s. What is the velocity afer 3 seconds have passed?
Answer:
Final speed of the stone, v = 35 m/s
Explanation:
It is given that,
Initial speed of the stone, u = 5.6 m/s
Let v is the velocity of the stone after 3 seconds have passed. It is moving down under the action of gravity. So, using the first equation of motion as :
[tex]v=u+at[/tex]
[tex]v=u+gt[/tex]
[tex]v=5.6+9.8\times 3[/tex]
v = 35 m/s
So, the final speed of the stone is 35 m/s. Hence, this is the required solution.
if m represents mass in kg, v represents speed in m/s, and r represents radius in m, show that the force F in the equation F=mv^2 /r can be expressed in the unit kg×m/s^2

in which of these reaction is energy released
all reactions
no reactions
endothermic
exothermic
The correct answer is D. Exothermic
Explanation:
One of the features used to classify reactions is whether energy is released or absorbed during them. In this way, when the reaction causes energy to be absorbed this is classified as endothermic; an example of this is when an ice cube melts because it absorbs heat from the environment. On the other hand, if energy is released, the reaction is exothermic; for example, fire releases heat, and therefore this reaction is exothermic. According to this, it can be concluded not all reactions release energy but only exothermic reactions.

The amount of water in reservoirs is often measured in acre-ft. one acre-ft is a volume that covers an area of one acre to a depth of one foot. an acre is an area of 43 560 ft2. find the volume in si units of a reservoir containing 22.0 acre-ft of water.
Final answer:
The volume of the reservoir containing 22.0 acre-ft of water is approximately 89031.92 cubic meters (m³).
Explanation:
To find the volume in SI units of a reservoir containing 22.0 acre-ft of water, we need to convert the given volume from acre-ft to cubic meters (m³).
First, let's convert 1 acre to square meters (m²). We know that 1 acre is equal to 43,560 square feet (ft²). Therefore, 1 acre is equal to 43,560 ft² * (1 m² / 10.764 ft²) = 4046.86 m² (rounded to two decimal places).
Next, we convert 1 acre-ft to cubic meters. Since 1 acre-ft is defined as the volume that covers an area of one acre to a depth of one foot, we multiply the area in square meters (4046.86 m²) by the depth in feet. Therefore, 1 acre-ft is equal to 4046.86 m² * 1 ft = 4046.86 m³ (rounded to two decimal places).
Finally, to find the volume of the reservoir containing 22.0 acre-ft of water, we multiply the conversion factor (4046.86 m³/acre-ft) by 22.0 acre-ft.
22.0 acre-ft * 4046.86 m³/acre-ft = 89031.92 m³ (rounded to two decimal places).
Therefore, the volume of the reservoir containing 22.0 acre-ft of water is approximately 89031.92 cubic meters (m³).
What is the velocity of a jet plane that travels 528 meters east in 4 seconds?
The velocity of a jet plane that travels 528 meters east in 4 seconds is calculated using the formula v=d/t. Substituting the given values we get the velocity as 132 meters per second east.
Explanation:To calculate the velocity of the jet plane, we will use the straightforward formula for velocity. According to physics, velocity (v) is equal to the displacement divided by the time taken, v = d/t. In this case, the jet plane travels 528 meters east in 4 seconds. So we will substitute these values into the formula to find the velocity. Velocity = 528 meters / 4 seconds = 132 meters per second. Thus, the velocity of the jet plane is 132 meters per second towards the east.

Explain how scientific knowledge develops through making observations about the natural world
Scientific knowledge develops through making observations about the natural world. An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested through experimentation. The results of experimentation lead to changes in scientific knowledge.
edgen answer
Scientific knowledge develops through making observations about the natural world by doing experiments and scientific investigation.
What is scientific investigation?Scientific investigation is the process of looking for answers by doing extensive research and finding the answers through experimental results.
The scientific investigation very much relies on true experimental results that can be supported by evidence.
As theories and propositions are developed, tested against observations of the natural world throughout time, and refined in response to new information and findings, scientific knowledge is accumulated.
Conducting observations about the natural world is how science learns. A discovery could spark a hypothesis-generating scientific inquiry. Experiments can be used to verify the theory. The outcomes of experiments alter our understanding of science.

Another name for prison or jail terms is which of the following? misdemeanors felonies laws sentences
Answer:D
Explanation:
Final answer:
The terms 'sentences' refer to the legal consequences imposed for committing a crime, including prison or jail time. Misdemeanors typically lead to shorter jail sentences, whereas felonies can result in longer incarceration in prison. Alternative sentencing options are also available, such as probation or rehabilitation.
Explanation:
Another name for prison or jail terms is sentences. A sentence is the formal legal consequence imposed by a court upon a person who is convicted of a crime. Misdemeanors are less serious crimes compared to felonies, and they often result in incarceration for one year or less, which typically occurs in a local jail rather than a state or federal prison. Felonies are more serious crimes and can lead to longer periods of incarceration in state or federal prisons. Alternative sentencing options, such as probation, rehabilitation, or home confinement, might also be used instead of jail time, particularly in the case of misdemeanors.
Prisons and jails serve different purposes; jails typically house individuals awaiting trial or serving short sentences, while prisons are for those serving longer sentences. The choice between sentencing someone to jail or prison often depends on the severity of their crime and the length of the sentence imposed.
