Answer:
speed = distance/time
Explanation:
speed = 150/30
speed =5m/s
you were running fast .....5m/s is a good speed
In order to create a charged object you need to transfer electrons either away or to the object by induction, conduction, or friction
Induction is without contact(like bringing a charged object to a electroscope charges the leaves at the bottom)
Conduction is with contact(like the previous answer, wore touching transfers the charge from a source to the object)
Friction(rubbing a balloon on wool)
Answer:
friction, conduction and induction
Explanation:
Had it in class I had it correct hope this helps.
Answer:0.43
Explanation:
Given
mass of car ![m=2400 kg](https://tex.z-dn.net/?f=m%3D2400%20kg)
Speed of car ![u=14 m/s](https://tex.z-dn.net/?f=u%3D14%20m%2Fs)
Distance traveled before coming to halt ![s=23.2 m](https://tex.z-dn.net/?f=s%3D23.2%20m)
Let
the coefficient of friction
Maximum deceleration road can provide during motion is
![a=\mu g](https://tex.z-dn.net/?f=a%3D%5Cmu%20g)
using ![v^2-u^2=2 as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2%20as%20)
![0-14^2=2\cdot (-\mu g)\cdot 23.2](https://tex.z-dn.net/?f=0-14%5E2%3D2%5Ccdot%20%28-%5Cmu%20g%29%5Ccdot%2023.2)
![\mu =\frac{196}{454.72}](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7B196%7D%7B454.72%7D)
![\mu =0.431](https://tex.z-dn.net/?f=%5Cmu%20%3D0.431)
The animal that is hunted and consumed is considered the prey
