Answer:
Vector K = 8 m
Explanation:
The given figure shows a right angle triangle JKL. It is given that :
vector L = 10 m
vector J = 6 m
We have to find vector k. We can find it by using Pythagoras theorem. According to this theorem, the sum of squares of perpendicular and the base is equal to the square of the longest side.
K = 8 m
Hence, the magnitude of vector K is 8 m.
Answer:
18.73 m/s^2
Explanation:
f = 2662 rpm = 2662 / 60 rps
r = 6.725 cm = 0.06725 m
Acceleration, a = r w
a = r x 2 x pi x F
a = 0.06725 × 2 × 3.14 × 2662 / 60
a = 18.73 m/s^2
In liquids, molecules particles are close together but move in random directions.
In solids, they are closely packed together and they vibrate a little.
In gases, they love around really quickly and are farther apart (even more than liquids).
<span>When Kevin pulls his cotton shirt off his body, the electrons get transferred from the shirt (in form of static charges i.e. electrons to the body. So, the shirt becomes positively charged and Kevin’s body becomes negatively charged.
As a result of charge transfer from the shirt to the body, we can hear a crackling sound. or if observed in dark, a sparkle can be seen.</span>
