This is a problem based on the logic and interpretation of the variables. From the measured data taken
what is collected by the two individuals is expressed as,
- NED reference system: (x, t)
- PAM reference system: (x ', t')
From the reference system we know that ν is the speed of PAM (the other reference system) as a measurement by NED.
Then ν' is the speed of NED (from the other system of the reference) as a measurement by PAM.
Answer:
no additional information required.
Explanation:
given,
vertical height, h = 35 m
acceleration due to gravity, g = 9.8 m/s²
time taken by the bullet to fall in the water = ?
initial vertical velocity of the bullet = 0 m/s
using equation of motion for the time calculation
t = 2.67 s
The time taken by the bullet to fall in the ocean is equal to 2.67 s.
Hence, there is no additional information required.
Answer:
P1 = 2680 pa P2 = 4870pa
T1 = 273k T2 = T
From the ideal gas equation,
P1 / T1 = P2 / T2
2680 / 273 = 4870 / T
T = 4870 * 273 / 2860
T = 496.38 k

The average speed in m/s of a person that jogs eight complete laps around a 400m track in a total time of 15.1 min is 0.44m/s.
<h3>How to calculate average speed?</h3>
Average speed of a moving body can be calculated by dividing the distance moved by the time taken.
Average speed = Distance ÷ time
According to this question, a person jogs eight complete laps around a 400m track in a total time of 15.1 min. The average speed is calculated as follows:
15.1 minutes in seconds is as follows = 906 seconds
Average speed = 400m ÷ 906s
Average speed = 0.44m/s
Therefore, the average speed in m/s of a person that jogs eight complete laps around a 400m track in a total time of 15.1 min is 0.44m/s.

Answer:
c. streak
Explanation:
Pyrite is a mineral that looks like gold but actually is iron disulfide.
Pyrite and gold have comparable luster.
Pyrite and gold have different tones of yellow. This can be determined by their streak. Streak is the powdered form of a mineral. A streak of mineral can be found just by rubbing the mineral on a rough surface and comparing the colors.
Pyrite is diamagnetic which is not a strong form of magnetism. Gold is also diamagnetic
