Answer:
The total charge on the rod is 41.18 nC
Explanation:
Given;
length of glass rod, L = 10 cm = 0.1 m
radius of the rod, r = 4 cm = 0.04 m
Force of repulsion = 940 μN = 940 × 10⁻⁶ N
Charge on the bead = 6.5 nC = 6.5 × 10⁻⁹ C
Charge on the rod, Q = ?
From coulomb's law;
Where;
F is the force of repulsion in N
q₁ and q₂ are the charges on the bead and rod
R is the resultant distance between the two charges;
K is coulomb's constant = 8.99 x 10⁹ Nm²/C²
Therefore, the total charge on the rod is 41.18 nC
Answer:1.8 hr
Explanation:
Given
mass of cargo=500,000 kg
initial speed
Frictional force=85 v
at t=0 engine is shut off so acquired speed is slowly decreasing
Integrating both sides
t=6462.425 s
t=1.8 hr
Answer:
Explanation:
Given data:
Weight W = 16 lb
length l = 6/12 = 0.5 ft
hence, spring constant k = W/l = 16/0.5 = 32 lb/ft
The equation of motion of spring is
the auxiliary equation can be written as
The discriminate of equation is
To get the value of the damping constant,
The answer for your diving board would be 7.2
