Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring consta

nt of spring 1 is 245 N/m. The motion of the object on spring 1 has twice the amplitude as the motion of the object on spring 2. The magnitude of the maximum velocity is the same in each case. Find the spring constant of spring 2.

Answer:1080 N/m

Explanation:

Given

Spring constant of first Spring K_1=245 N/m

mass of both the system is same

Both system have same maximum velocity

if x=A\sin \omega t is general equation of SHM

then maximum velocity is given by

v_{max}=A\omega

\omega =\sqrt{\frac{k}{m}}

v_1_{max}=A_1\omega _1

\omega _1=\sqrt{\frac{k_1}{m}}

similarly \omega _2=\sqrt{\frac{k_2}{m}}

also A_1=2A_2

so A_1\times \sqrt{\frac{k_1}{m}}=A_2\times \sqrt{\frac{k_2}{m}}

2\times \sqrt{k_1}=\sqrt{k_2}

k_2=4k_1

k_2=4\times 245=1080 N/m

How does the heat enhance <br>the rate of chemical reaction ? Explain in short.​
densk [106]
When the reactants are heated, the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy. If more molecules hit each other with enough energy to react, then the rate of the reaction increases.

Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuri
ch4aika [34]
The larger the mass the mass and the speed, the larger the force it would produce if it crashes something. Some car crashes produce minor injuries because maybe this car is small and runs at very slow speed which would mean less force when in impact with another. However, if a big truck crashes, it is expected to produce a larger force causing catastrophic injuries.

An independent-measures design is also known as a _______________ design.
lesya692 [45]

An Independent Group/ between-subjects design differs from a within-subjects design in that a between-subjects design. The correct option is B.

<h3>What is independent measure design?</h3>

Studying between subjects (or between groups): As various subjects are used to test each condition, each subject is only exposed to a single user interface. internal topic (or iterative measurement) The same topic evaluates every circumstance (that is, all user interfaces).

Each participant in a topic or intergroup design only encounters one condition, and the group differences between individuals under various conditions are compared. The in-subject design, in which every participant is exposed to every condition, is the antithesis of this.
