Answer:
kinematic viscosity in SUS is = 671.64 SUS
Explanation:
given data
kinetic viscosity = 145 mm^2/s
we know
1 mm = 0.1 cm
so kinetic viscosity in cm is 
other unit of kinetic viscosity is centistokes

so 1.45 cm^2/s will be 145 cst
if the temperature is 260°f , then cst value should be multiplied by 4.632. therefore kinematic viscosity in SUS is = 4.362 *145 = 671.64 SUS
Answer:
The right answer is "1.369 m/s²".
Explanation:
The given values are:
Distance (s)
= 260 m
Initial speed (u)
= 26 m/s
Reaction time (t')
= 0.51 s
During reaction time, the distance travelled by locomotive will be:
⇒ 


Remained distance between locomotive and car:
⇒ 


Now,
The final velocity to avoid collection is, V = 0 m/s
From third equation of motion:
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Explanation:
upthrust is the same as Force
And the dimension of Force is MLT-2
The -2 is going to be in raise to power form....
Hope it helps....
This should be the answer
