a body of a mass 1kg suspended from a spring is found to stretch the spring by 10cm. (A) what is the spring constant? what is pe

Nikitich [7]

Answer:

(A) The spring constant is 98 N/m.

(B) The period of oscillation is 0.635 s.

Explanation:

Given:

Mass of the body is, $m=1\ kg$

Extension length of the spring is, $x=10\ cm=0.1\ m$

Now, let 'k' be the spring constant.

The force acting on the body is due to gravity only and is equal to its weight.

So, weight of the body is given as:

$F_g=mg\\F_g=1\times 9.8\\F_g=9.8\ N$

Now, we know that for a spring-mass system, the net force acting on the body is equal to the product of the spring constant and extension length. Therefore,

$F_g=kx\\9.8=k(0.1)\\k=\frac{9.8}{0.1}=98\ N/m$

Hence, the spring constant is 98 N/m.

(B)

Period of oscillation of a body of spring-mass system in SHM is given as:

$T=2\pi\sqrt{\frac{m}{k}}$

Plug in the given values and solve for period 'T'. This gives,

$T=2\pi\sqrt{\frac{1}{98}}\\T=2\pi\times 0.101\\T=0.635\ s$

Therefore, the period of oscillation is 0.635 s.

PilotLPTM [1.2K]

Let the unknown distance be xmiles
x/39-x/72=11hr
72x-39x/2808=11hr
33x/2808=11
33x= 30888
x=936miles
U can substitue back to check
at speed of 72mph, he would need 936/72=13hrs
at speed of 39mph, he would need 936/39=24hr
the difference is 24-13=11

9. Seismic waves are

Brilliant_brown [7]

d. both a and b

Explanation:

Seismic waves are both transverse and compressional or longitudinal waves.

A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.

Seismic waves are both longitudinal and transverse waves.
There are two main types of seismic waves which are the surface and body waves.
The surface waves runs on the earth surface. These are the rayleigh and love waves.
The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
Body waves moves within the earth surface. They are p-waves and s-waves.
P-waves are longitudinal or compressional waves that propagates within the earth surface.
S-waves are transverse waves that moves perpendicularly to their direction of propagation.
