Answer:
25N
Explanation:
formula=> Frictional force= coefficient of friction x normal reaction
normal reaction is mass x gravity(10N/kg)
so Frictional force= 0.5x5x10
=25N
but that is the Frictional force not the constant force
to get the constant force, subtract the Frictional force from the weight of the block
weight= mass x gravity
= 5x10
= 50N
50N-25N
=25N
Answer:
161000 J
Explanation:
Please do mark as brainliest. Hope this helps! :)
It allows people to see around the corner and anticipate what speed changes they will need to make
v = 
and
a = 
We have acceleration and velocity so:
3 = 
88.3 = 
In the acceleration equation we can isolate for v and then plug it back into the other equation to solve...
So...


Divide by three and
t = 29.4 s
Hi
we know that
density=mass/volume
mass of liquid =6g= 6x10^-3kg.
volume of liquid=12ml=12x10^-3litre
density=6x10^-3/12x10^-3
=.5kg/liter
thanks for asking
