Answer:
W, because that's the highest point
Explanation:
The forces on the y axis are:
N-mgcos(60)=0 , wich becomes
N=mgcos(60)
Rember that the friction force is always contrary to the motion of an object and its formula is f=μ * N
The forces in the x axis are:
-f + mgsin(60)= m * a
-μ*mgcos(60) + mgsin(60)=m*a ,
μ = ( m*a - mgf=μ[sin(60) )/ ( mgcos(90) )
Two ways that strong nuclear and weak nuclear forces are alike: Strong nuclear and weak nuclear their alike because they deal with atoms and subatomic particles. ... Two ways that electromagnetic force and gravity are alike: Electromagnetic force and gravity are alike because both of them has an infinity force.
<span>Answer:
I'm pretty sure the SA / V ratio would get smaller. Assume that the cell is more or less spherical. SA = 4(pi)r^2, while V = (3/4)(pi)r^3. The ratio = (4(pi)r^2)/((3/4)(pi)r^3), which can be simplified to 3/r. Thus, the larger r gets, the smaller the ratio becomes.</span>
