To hop 30 meters at a rate of 5 meters per second, it would take 6 seconds, calculated using the formula t = d/v where t is time, d is distance, and v is velocity.
Explanation:If you hopped at a rate of 5 meters per second (m/s), to cover a distance of 30 meters, you would use the basic formula for distance, which is distance equals speed times time (d = vt). Here, you want to find the time (t), so you rearrange the formula to t = d/v.
Substituting in our known values gives us t = 30 m / 5 m/s, which simplifies to t = 6 seconds. Therefore, it would take you 6 seconds to hop 30 meters at a speed of 5 m/s.

What is the speed, in m/s, of a wave on a cord if it has a wavelength of 4m and a period of 0.5 s
SOMEBODY PLEASE HELP!!! Indicate the reasons why the centripetal acceleration (and centripetal force) always point to the center in uniform circular motion. Select all that apply.
A.) The v points toward the center of the circle.
B.) The t points toward the center of the circle.
C.) F=ma and since "a" points toward the center, so does F.
D.) F=ma and since "m" points toward the center, so does F.
(V=velocity)(T=time)(A=acceleration)(F=force)(M=mass)
Answer:
The correct answer is a=(triangle)v/(triangle)t, and the (triangle) v points toward the center of the circle. AND C. F=ma, and since “a” points toward the center, so does F.

In your own words, explain how Doppler radar works. Describe the properties of electromagnetic waves and interactions that make Doppler radar possible. (13 points)
If you stand up in a big room and echo, your voice will echo from the walls. As long as the room is empty. Since the speed of sound is constant, depending on air density, the more humid the air the faster and farther sound travels. The speed of sound is constant, you could measure the time it takes for your voice to echo off the walls. The same thing happens with Doppler radar, but it’s not voice, it has higher frequency signals.
Doppler Radar uses Doppler Effect as a principle to measure velocities, detect the presence of objects, identify meteorological phenomena and their intensity levels. This radar emits a continuous radio signal that allows the radar to differentiate between objects that are stationary and those in motion. This radar can be used, for example, to measure the speed of a particular object and to indicate its location, so that it is widely used in traffic surveillance.
Doppler radar is the most widely used type of weather radar that is currently of utmost importance for atmospheric monitoring. It is also employed for example in agriculture, air traffic and weather forecasting. Information gathered by radar assists meteorologists in early diagnosis of natural disasters.
Doppler effect, used by these radas, is a physical phenomenon observed in waves emitted or reflected by a source. It is perceived, for example, when listening to the sound of an ambulance passing by an observer. As the ambulance approaches, the tone becomes more and more acute, and as it moves away it becomes more serious. What happens is that we perceive a relative frequency, which is not the same frequency as the wave was emitted.

A platinum bar measures 5.0 cm long, 4.0 cm wide, and 1.5 cm thick. It has a mass of 750.0 grams. Don't forget to find the volume of the bar (L X W X H). Use the formula D=m/v Calculate the density of the platinum bar (you need the volume first). Enter your answer in the space provided.
The density of the platinum bar is found by first calculating the volume (5.0 cm*4.0 cm*1.5 cm = 30.0 cm^3). Then, using the formula D=m/v, we divide the mass (750.0 grams) by the volume to find the density, which is 25.0 g/cm^3.
Explanation:The density of a material is calculated by using the formula: D=m/v, where 'D' is the density, 'm' is the mass, and 'v' is the volume. In this case, we need to find the volume of the platinum bar first. The volume is determined by multiplying length, width, and height. Thus, you multiply 5.0 cm by 4.0 cm by 1.5 cm, which equals 30.0 cm^3.
Once you have the volume, you can determine the density of the platinum. The mass given is 750.0 grams. Therefore, density (D) is mass divided by volume. When you divide 750.0g by 30.0 cm^3, the calculated density becomes 25.0 g/cm^3.

The wolves and moose of Isle Royale are the focus of the longest-running study of a predator-prey system in the wild. Both are recent arrivals to Isle Royale: moose swam to the island in the early 1900’s. Wolves followed decades later, traveling over the ice from Canada in the 1940’s.About 40 years into the study, the wolf population crashed when humans introduced the canine-parvovirus. Additional factors over the years have impacted both populations. At one point during the study, the moose population collapsed during the most severe winter on record followed by an outbreak of moose ticks. What point on the graph represents the outbreak of moose ticks and a drastic decline in the moose population?
A) Point A
B) Point B
C) Point C
D) Point D
Point C is the answer
Answer:
We have been given two cases of Wolves and moose of Isle Royale
We need to tell the outbreak of moose ticks and a drastic decline in the moose population.
We can see from the graph that A and B are representing Wolves
So, Option A and B are discarded.
Now, we should know the meaning of Outbreak in a graph which means that the large number of people are represented by a single point.
Point C is representing large number of people at one point
So, Outbreak of Moose ticks is represented by Point C.
Now, the drastic decline is the point where the curve started to decrease
At point D the curve is decreasing
Hence, the drastic decline is at the point D.

Explanation:
All parts of the electromagnetic spectrum travel at a speed of 3 × 108 m/s when traveling through no medium. A "vacuum” means that there is no medium, such as a tube without any air in it. Therefore, 3 × 108 m/s is said to be the speed of light in a vacuum. If an electromagnetic wave’s frequency doubles in a vacuum, what are the other effects on the wave? Wavelength doubles and speed doubles. Wavelength doubles and speed stays the same. Wavelength divides in half and speed doubles. Wavelength divides in half and speed stays the same
Answer:
the answer is D.
Explanation:
Answer:D. wavelength divides in half, and speed stays the same

what happens when velocity and acceleration are not in the same direction?
Acceleration is the rate at which velocity changes, which means that acceleration tells you how fast the velocity is changing. A large acceleration tells you that the velocity is changing quickly - a small acceleration tells you that the velocity is changing slowly - an acceleration of zero tells you that the velocity is not changing at all.
Acceleration tells you how the velocity changes - it doesn't tell how how much the velocity is! An object can have a large velocity and a small (or zero) acceleration - and vice versa.
if the same amount of energy is added to 5 g of water and to 50 g of water, which sample will have the higher temperature
What two roles do forensic engineers play?
Accident reconstructions and failure evaluations of vehicles and structures are the two roles that performed by forensic engineers.
What is forensic engineering?When reconstructing crimes and accidents and figuring out their causes, forensic engineering makes use of ideas from mechanical, chemical, civil, and electrical engineering. Reconstruction of auto accidents is a significant part of that effort. Forensic engineers analyze information from skid marks, damage to cars and their locations after collisions, road and environmental conditions, injuries to drivers, passengers, and pedestrians, and witness testimony to assess what might have caused the accident.
Accident reconstructions and failure evaluations of vehicles and structures are performed by forensic engineers. In order to comprehend the physical dynamics of the 1995 Oklahoma City bombing and to provide an explanation for the fall of the World Trade Center's twin towers during the September 11 attacks in 2001, forensic engineering was crucial. Police investigations into auto accidents can benefit from forensic engineering.
