Answer:
α = 17.0 rad/s²
Explanation:
For this problem let's use the torque expression
τ = I α
Torque is the product of force by the distance that is half the length of the pencil
τ = F x
Let's use trigonometry
sin 10 = x / (l / 2)
x = l / 2 sin 10
τ = mg l /2 sin 10
The moment of inertia of pencil that we approximate as a rod with the axis of rotation at one end
I = 1/3 m L²
We replace
mg l / 2 sin 10 = 1/3 m l² α
α = 3/2 g/l sin 10
Let's reduce the magnitudes to the SI system
l = 15.0 cm = 0.150 m
m = 10.0 g = 0.0100 kg
Let's calculate
α = 3/2 9.8 / 0.150 sin 10
α = 17.0 rad/s²
Answer:
acidic colorless gas
Explanation:
Carbon dioxide is an acidic colorless gas with a density of about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
The higher the voltage, the lower the current. ... The lower current that accompanies high voltage transmission reduces resistance in the conductors as electricity flows along the cables. This means that thin, light-weight wires can be used in long-distance transmission.
One form of Ohm's law says:
Voltage = (current) x (resistance).
= ( 9 A ) x (43 ohms)
= 387 volts.
Choice-A says this.
