Answer:

Following are the answer to this question:

Explanation:

The wave is propagating at the incident wave which focuses on the stretchy and rotational inertia features of the whole medium via a material system. For both the mechanical waves there are many two basic types of incident waves: quality management program and transverse waves.

The rumor is also known as the "Norman Rockwell", in which the environment of some of the greatest physics attempts of our time, it pays to remain suspicious when remarkable reports of historical findings are made on social media.

When a mass of 0.350 kg is attached to a vertical spring and lowered slowly, the spring stretches 0.120 m. The mass is now displ

AURORKA [14]

Answer:

Time period of the oscillation will be 0.695 sec

Explanation:

We have given mass attached to the string m = 0.350 kg

The spring is stretched by 0.120 m

So x = 0.120 m

We know that force is given by F = Kx

So mg = kx

$0.350\times 9.8=k\times 0.120$

k = 28.5833

Now time period is given by

$T=2\pi \sqrt{\frac{m}{k}}=2\times 3.14\sqrt{\frac{0.35}{28.5833}}=0.695sec$

So time period of the oscillation will be 0.695 sec

As a train accelerates away from a station, it reaches a speed of 4.6 m/s in 5.2 s. If the train's acceleration remains constant

Svet_ta [14]

Answer:

Vf = 10.76 m/s

Explanation:

Train kinematics

The train moves with uniformly accelerated movement

$V_f = V_o + a*t$ Formula (1)

Vf: Final speed (m/s)

V₀: Inital speed (m/s)

t: time in seconds (s)

a: acceleration (m/s²)

Movement from t = 0 to t = 5.2s

We replace in formula (1)

4.6 = 0 + a*5.2

a = 4.6/5.2 = 0.88 m/s²

Movement from t = 5.2s to t = 5.2s + 7s = 12.2s

We replace in formula (1)

$V_f = 4.6 + 0.88*7$

Vf = 10.76 m/s
