The term used is " WORK".
I'm really sorry it's not one of the choices.
Answer: Addition polymerization & Condensation polymerization
0.0605J is your answer. Use the formula KE=1/2mv^2
Answer:
.409 N
Explanation:
For this to balance, the moments around the fulcrum must sum to zero.
On the left you have .21 ( is that down? I will assume it is)
Counterclockwise moments :
.21 * 40 + 1.0 * 20
Clockwise moments :
.5 * 20 + F * 45
these moments must equal each other
.21*40 + 1 *20 = .5 * 20 + F * 45
F = .409 N
Answer:
ans:
tenson(T) = 20 N
acceleration (a) = 2.86 m/s
Explanation:
T + mg = Mg
T = Mg - mg
T = g( M - m )
T = 10× ( 7-5 )
T = 20 N
again;
T = 20
Ma = 20
a = 20 / 7
= 2.86 m/s
