- Kinetic Energy of an object is the measure of the work an object can do by virtue of its motions..
- Where KE is the kinetic energy, m is the body’s mass, and v is the body’s velocity.
- Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts..
Where,
. m is the mass in kilograms
. g is the acceleration due to gravity
. h is the height in meters
Hope it helpz~ uh..
PCBs were found in greater concentrations in lakes where more salmon spawned.
It would go slower there needs to be more gravity to go faster
Answer:
0.13
Explanation:
Draw a free body diagram. There are three forces:
Weight force mg pulling down.
Normal force N pushing perpendicular to the incline.
Friction force Nμ pushing parallel up the incline.
Sum of the forces perpendicular to the incline:
∑F = ma
N − mg cos θ = 0
N = mg cos θ
Sum of the forces parallel down the incline:
∑F = ma
mg sin θ − Nμ = ma
mg sin θ − mgμ cos θ = ma
g sin θ − gμ cos θ = a
gμ cos θ = g sin θ − a
μ = (g sin θ − a) / (g cos θ)
Given a = 3.3 m/s² and θ = 27°:
μ = (9.8 m/s² sin 27° − 3.3 m/s²) / (9.8 m/s² cos 27°)
μ = 0.13
Answer:
we have τ = I * α as the rotational equation of motion
and we also have τ = F * r
so the torque τ = 5* 0.16 Nm = 0.8 Nm
from your plot of θ vs T^2 , calculate the slope of the line
this slope will be angular acceleration α.
Then you get I = τ/α
