Answer:
v = 98.4 m/s
Explanation:
As we know that the total angular momentum of the system is conserved
so here we will have
now plug in all data
Answer:
Quantity of charge = 36 Coulombs.
Explanation:
Given the following data;
Current = 20 mA = 20/1000 = 0.02 Amperes
Time, t = 30 minutes to seconds = 30 * 60 = 1800 seconds
To find the quantity of charge;
Quantity of charge = current * time
Quantity of charge = 0.02 * 1800
Quantity of charge = 36 Coulombs.
Use kinematic equation:
vf² = vo² + 2g(xf - xo)
vf = final velocity = 10 m/s
vo = initial velocity = 0 m/s (i.e. at rest)
g = 9.81 m/s²
xf - xo = distance traveled = d
*rearrange equation to solve for d
(vf² - vo²)/(2g) = d
d = ((10 m/s)² - (0 m/s)²)/(2*9.81 m/s²)
d = (100 m²/s²)/(2*9.81 m/s²)
d = 5.097 m
False
Balanced forces mean that there is no net force acting on the object. therefore, the object will not accelerate.
