Answer:
0.6944 m/sec^2
Explanation:
The computation of the average acceleration is given below:
a = v - u ÷ t
where
a denotes average acceleration
v denotes final velocity
u denotes initial velocity
t denotes time
So, the average acceleration is
= (25 - 0) ÷ 10
= 0.6944 m/sec^2
Answer:
F1= 196 N
F2= 392 N
Explanation:
Given:
length of the plank = 2 m
mass of the plank = 20 kg
Weight of the plank = 20 x 9.8 =196 N
Torque due to the weight of the plank with respect to the pivoted end (i.e the end held by the hand) Counter clockwise torque = 196 x cog of wood
= 196 x 1 = 196 Nm
Clockwise torque = F2 x 0.5
for the balanced case
F2 x 0.5 = 196
F2 = 196/ 0.5
F2= 392 N
now,
the net force
Net downward force =Net upward force
F1 + weight of plank = F2
F1 + 196 = 392N
F1 = 392 – 196
F1= 196 N
Answer:
<h3>Because one Coulomb of charge is an abnormally large quantity of charge, the units of microCoulombs (µC) or nanoCoulombs (nC) are more commonly used as the unit of measurement of charge. To illustrate the magnitude of 1 Coulomb, an object would need an excess of 6.25 x 1018 electrons to have a total charge of -1 C.</h3>
