The kinetic energy registers at 100,000 Joules when a roller coaster weighing 2000 kg rolls down a track at an instantaneous speed of 10 
.
Explanation:
The details provided are as follows:
Mass - 2000 kg
Instantaneous speed - 10 meters per second
Step 1
The formula for calculating kinetic energy is given by
....................(1)
Here, K.E refers to kinetic energy in joules
m denotes mass in kg
and v represents velocity or speed in meters per second
Step 2
According to the provided information:
m = 2000 kg
v = 10
Thus, equation (1) transforms to
= (0.5)(2000)(100)
= 100000
K.E equals 100,000 Joules
Result:
The kinetic energy registers at 100,000 Joules when a roller coaster weighing 2000 kg rolls down a track at an instantaneous speed of 10 .
Individuals inherit one factor per trait from each parent, and a dominant factor can conceal the expression of a recessive one when both are present.
Answer:
44.4m/s^2
Explanation:
Utilize the equation...S = ut + 1/2at^2
where...S = 32m...u = 0m/s....t = 1.20s
32 = (0)(1.20) + 0.5(1.20^2)a
; The acceleration due to gravity is 44.4m/s^2
Referencing the diagram below, we can deduce from the geometry that x = 2.5 - 0.55 = 1.95 m, leading to cos θ = 1.95/2.5 = 0.78. Therefore, θ = cos⁻¹ 0.78 = 38.74°. According to the free body diagram, the tension in the chain measures 450 N. Here, F denotes the centripetal force and W signifies Dee's weight. The tension's components are as follows: Horizontal component = 450 sin(38.74°) = 281.6 N, directed to the left, and Vertical component = 450 cos(38.74°) = 351.0 N, directed upward. Answers: Horizontal: 281.6, directed left. Vertical: 351.0 N, directed upward.
According to Snell’s Law:
Where: is the index of refraction of the first medium (glass), and is the index of refraction of the second medium (ice). The angle of incidence and the angle of refraction are represented by and. The refractive index quantifies the speed of light in a medium. The critical angle is identified as the angle at which total internal reflection occurs, meaning no light passes through into another medium. This phenomenon happens only when the light is transitioning from a medium with a higher index of refraction to one with a lower index of refraction.
