A
Explanation:
because thats what I put and got it right
Answer:
ω = 3.1 rad/s
θ = 36° from vertical
Explanation:
I will ASSUME that the bob and string is acting as a pendulum.
Please understand that the string will break when the bob is at the lowest point of the swing where the vectors of gravity and centripetal acceleration align. It will NOT break at the angle of maximum inclination measured from vertical. This angle is only a component of the maximum potential energy that gets converted to maximum kinetic energy at the lowest point of the swing.
At the bottom of the swing, the string must support the weight of the bob plus supply the required centripetal acceleration.
F = mg + mω²R
F/m = g + ω²R
F/m - g = ω²R
ω = √((F/m - g)/R)
ω = √((3/0.220 - 9.8)/0.40)
ω = 3.09691...
ω = 3.1 rad/s
Potential energy will convert to kinetic energy
mgh = ½mv²
h = v²/2g
R - Rcosθ = v²/2g
R(1 - cosθ) = v²/2g
1 - cosθ = v²/2gR
cosθ = 1 - v²/2gR
cosθ = 1 - (Rω)²/2gR
cosθ = 1 - Rω²/2g
cosθ = 1 - 0.40(3.1²)/(2(9.8))
cosθ = 0.804267
θ = 36.46045...
θ = 36°
Answer:
La danza, el movimiento del cuerpo de manera rítmica, generalmente con música y dentro de un espacio determinado, con el propósito de expresar una idea o emoción, liberar energía o simplemente deleitarse con el movimiento en sí. La danza es una forma de arte escénico que consiste en de secuencias de movimiento humano seleccionadas a propósito. Este movimiento tiene un valor estético y simbólico, y es reconocido como danza por artistas y observadores dentro de una cultura particular.
Option D is the correct answer. Option C is incorrect cuz temperature is not constant in outer space which makes difficult for classification. So composition of objects matters. Hence D. Hope it helps.
Braking-induced traction loss occurs in the rear wheels of a vehicle.
<u>Explanation:</u>
The extent to which the tires or wheels of a vehicle can have grip on the surface of the road is refereed to as traction. When a vehicle moves at a faster rate or at high speed, loss of traction can happen. During the times of rainy season going at high speed on road or road corners makes vehicles to lose grips.
Traction loss can happen when any of the things like over acceleration, applying over break, riding too fast or making the vehicles to turn too sharply. While riding a vehicle, when brakes are applied at a very harder rate, the tires of front and backside of the vehicle can get arrested. Thus the traction loss called Braking-induced traction loss occurs.
