jeremie ran around the track at the ymca for 2 hours. when he was done he figured that he had traveled 20 kilometers. what was his speed? what was his velocity
Jeremie's speed was 10 km/h . His velocity was 0 km/h since he returned to his starting point, resulting in zero displacement.
To find Jeremie's speed and velocity:
Time spent running: 2 hoursDistance traveled: 20 kilometersSpeed is calculated as the total distance travelled divided by the total time taken. Here, we can use the formula:Speed = Distance / Time
Speed = 20 km / 2 hours = 10 km/h
Next, we need to determine the velocity. Velocity is a vector quantity, which means it includes both magnitude and direction. Since Jeremie ran around a track and consequently returned to his starting point, the displacement is zero and therefore:Velocity = Displacement / Time
Given that the displacement is zero, the velocity is:
Velocity = 0 km / 2 hours = 0 km/h
So, Jeremie's speed was 10 km/h but his velocity was 0 km/h since he ended up at his starting point.

What are the two most abundant gases in the atmosphere
Answer:
Nitrogen represents 78% of the atmosphere, oxygen 21%.
Explanation:
The atmosphere is composed of a mixture of many different gases, which are found in different amounts. The permanent gases whose percentages do not change are nitrogen, oxygen, and argon.
Nitrogen represents 78% of the atmosphere, oxygen 21% and argon 0.9%. Other gases such as carbon dioxide, nitrous oxides, methane, and ozone represent a low percentage of the composition in the atmosphere.
Ultimately nitrogen and oxygen account for approximately 99% of the gases in the atmosphere.

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.

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.
what type of motion does the galaxy go through
Well, it depends. Your latitude on Earth--that is, how close you are to the equator--and the time of year make a difference. I'll explain why. Your motion is made up of four pieces: the rotation of the Earth on its axis, the motion of the Earth around the Sun, the Sun's orbit about the center of the galaxy, and the motion of the whole galaxy.

An astronaut weighs 104 newtons on the moon, where the strength of gravity is 1.6 newtons per kilogram.
a. What is her mass?
b. What is her weight on Earth?
c. What would she weigh on Mars?
Answer:
a) 65 kilogram
b) 637 newton
c) 242 newton
Explanation:
a) 1.6 newton is equivalent to 1 kilogram mass so
104 newton will be equivalent to 104 / 1.6 = 65 kilogram
b) her weight on the earth = mass x gravitational acceleration
= 65 x 9.8 = 637 newton
c) gravitational acceleration on the mars is 3,72 m per second squire so
weight on mars = 65 x 3.72 = 242 approx.
a. Her mass is 65 kg
b. Her weight on Earth is 637 N
c. She would weigh 241 N on Mars

Further explanationNewton's gravitational law states that the force of attraction between two objects can be formulated as follows:
[tex]\large {\boxed {F = G \frac{m_1 ~ m_2}{R^2}} }[/tex]
F = Gravitational Force ( Newton )
G = Gravitational Constant ( 6.67 × 10⁻¹¹ Nm² / kg² )
m = Object's Mass ( kg )
R = Distance Between Objects ( m )
Let us now tackle the problem !
[tex]\texttt{ }[/tex]
Given:
weight of astronaut on the moon = w_m = 104 N
strength of gravity on the moon = g_m = 1.6 N/kg
strength of gravity on earth = g_e = 9.8 N/kg
strength of gravity on mars = g = 3.7 N/kg
Asked:
a. mass of astronaut = m = ?
b. weight of astronaut on Earth = w_e = ?
c. weight of astronaut on Mars = w = ?
Solution:
Part (a):[tex]w_m = m g_m[/tex]
[tex]104 = m \times 1.6[/tex]
[tex]m = 104 \div 1.6[/tex]
[tex]\boxed{m = 65 \texttt{ kg}}[/tex]
[tex]\texttt{ }[/tex]
Part (b):[tex]w_e = m g_e[/tex]
[tex]w_e = 65 \times 9.8[/tex]
[tex]\boxed{w_e = 637 \texttt{ N}}[/tex]
[tex]\texttt{ }[/tex]
Part (c):[tex]w = m g[/tex]
[tex]w = 65 \times 3.7[/tex]

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

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.
