Answer:
Options A and D
Explanation:
In this question the student needs to collect these measurements in order to approximate the work done
A. The mass of the student
D. The final vertical height above the initial vertical position.
Workdone = mgh
m = mass
g = gravity = 9.8m/s²
h = vertical height between the initial and the final positions.
The vertical height has to be known as gravity only acts straight down.
Answer:
distance= 10 km
displacement= 7.21 km
Explanation:
distance= scalar (only magnitude)
displacement= vector (magnitude & direction)
distance= 6 km+ 4 km
= 10 km
displacement= shortest difference btwn 2 pts=
sqrt( 6^2+4^2)
sqrt(52)
7.21 km
Answer:
It is displaced.
Explanation:
As the coaster travels. The kinetic and potential energy shifts up and down. But when it shifts, some of the energy is displaced and lost.
The particles are either being absorbed or evaporating
EEG
Explanation:
EEG represents Electroencephalography. Neutrons in the brain carries electrical discharges and impulses all around from the spinal cord.
- In EEG, electrodes are placed on the scalp to record the electrical activities in the brain.
- This generates a trace called an electroencephalogram.
- This is an uninvasive method in which the electrodes did not come in direct contact with the neurons.
- Brain activities can be deduced from this process.
