. In a physics lab, you attach a 0.200-kg air-track glider to the end of an ideal spring of negligible mass and start it oscilla
cluponka [151]

Answer:

Spring constant, k = 1.16 N/m

Explanation:

It is given that,

Mass of the air track, m = 0.2 kg

Time, t = 2.6 s

Let T is the time period of the spring. The expression for the time and spring constant is given by :

T=2\pi \sqrt{\dfrac{m}{k}}

k=\dfrac{4\pi^2m}{T^2}

k=\dfrac{4\pi^2\times 0.2}{(2.6)^2}

k = 1.16 N/m

So, the spring’s force constant is 1.16 N/m. Hence, this is the required solution.

I need help on this physics problem.

Answer:

the speed of the nerve impulse in miles per hour is 201.59 mi/hr

Explanation:

Given;

the speed of the nerve impulse, v = 90.1 m/s

To convert this speed in meters per second to miles per hour, we use the following method;

1,609 meter = 1 mile

3,600 s = 1 hour

v(mi/h) = 90.1 \ \frac{m}{s} \times \frac{1 \ mile}{1,609 \ m} \times \frac{3,600 \ s}{1 \ hour} = (\frac{90.1 \times 3,600}{1,609} )\frac{mi}{hr} = 201.59 \ mi/hr

Therefore, the speed of the nerve impulse in miles per hour is 201.59 mi/hr
