Answer:
The velocity must be reduced to one third to stay on the road
Explanation:
The sideways force that friction must resist comes from the centrifugal acceleration due to the turn.
fc=mv2Rfc=mv2R
the frictional force is given by
ff=μmgff=μmg where μμ is the static friction coefficient
if the car is not to skid
fc≤fffc≤ff so
mv2R≤μmgmv2R≤μmg
v≤μgR−−−−√v≤μgR
thus vv varies as the square root of μμ
so if μμ is reduced by 9, vv must be reduced by 9–√=39=3
and thus the speed must be reduced to<u> 26</u> m/s

Thermal energy is converted to chemical energy.
Plants have cell walls, but animals do not because otherwise we wouldn't be able to move.
Answer:
Force on the proton will be 
Explanation:
We have given speed of proton is 20.3% of speed of light
Speed of light 
So speed of proton 
Magnetic field B = 0.00629 T
Charge on proton 
Angle between velocity and magnetic field 
Force on the proton is equal to 
He treated then with care he would get more help or what he needed
