Answer:

50 m/s

Explanation:

The motion of the roller coaster car parameters are;

The initial speed of the roller coaster, v = 2 m/s

The distance to reach the bottom, Δd = 200 meter

The time it takes to reach the bottom, Δt = 4 seconds

The speed at the bottom of the tracks = 22 m/s

The average speed, v_{ave} = Δd/Δt

∴ v_{ave} = (200 m)/(4 s) = 50 m/s

The average speed of the roller coaster ride over the 200 m drop, v_{ave} = 50 m/s

Effect of impurities and temperature to surface tension​
oksano4ka [1.4K]
In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action of liquid molecules that they have at the interface.

An apparatus similar to the one used in lab uses an oscillating motor at one end to vibrate a long rope with frequency f = 40 Hz
Mice21 [21]

Answer:

The displacement in t = 0,  

y (0) = - 0.18 m

Explanation:

Given f = 40 Hz , A = 0.25m , μ = 0.02 kg / m, T = 20.48 N

v = √ T / μ

v = √20.48 N / 0.02 kg /m = 32 m/s

λ = v / f

λ = 32 m/s / 40 Hz = 0.8

K = 2 π / λ

K = 2π / 0.8 = 7.854

φ = X * 360 / λ

φ = 0.5 * 360 / 0.8 = 225 °

Using the model of y' displacement

y (t) = A* sin ( w * t - φ )

When t = 0

y (0) = 0.25 m *sin ( w*(0) - 225 )

y (0) = 0.25 * -0.707

y (0) = - 0.18 m

I which types of galaxy are globular clusters most likely to be found?
NemiM [27]
Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin globulus—a small sphere.
