Answer:

A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question

Position update: Initially the bottom of the block is at y = 0.12 m. Approximating the average velocity in the first time interv

aleksklad [387]

Answer:

The new position is 0.1865 m

Explanation:

As the context of the data is not available, thus following data is utilized from the question as attached above

x_relax=0.32 m

x_stiff=0.13 m

spring stiffness k=9 N/m

mass of block =0.073 kg

t=0.07 s

Velocity of the block is to be estimated thus

Force due to compression in spring is given as

F_s=k Δx

F_s=9(0.32-0.13)

F_s=1.71 N

Force on the block is given as

F_m=mg

F_m=0.073 x 9.8

F_m=0.71 N

Net Force

F=F_s-F_m

F=1.71-0.71 N

F=1 N

As Ft=Δp

Δp=1x0.07=0.07 kgm/s

Δp=p_final-p_initial

0.07=p_final-0

p_final=0.07 kgm/s

p_final=m*v_f

v_f=(p_final)/(m)

v_f=0.07/0.073

v_f=0.95 m/s

So now the velocity of the block is 0.95 m/s

time is 0.07 s

y_new=y_initial+y_travel

y_new=0.12+(0.95 x 0.07)

y_new=0.12+0.065

y_new=0.1865 m

So the new position is 0.1865 m

(1 points) Find the wavelength of a proton moving at 1.00% of the speed of light. The mass of a proton is 1.67 \times 10^{-27} ~

Iteru [2.4K]

Answer:

The wavelength of the proton will be $1.33\times 10^{-15}\ m$

Explanation:

Given the speed of the proton is $1.00 \%$ of speed of light.

And the mass of the proton is $1.67 \times 10^{-27}\ kg$ ..

We need to find the wavelength of moving proton.

As we know the speed of the light $c=2.998\times 10^8\ m/s$

So, speed of the proton will be

$1.00 \%(c)=\frac{1}{100}\times (c)=0.01\times 2.98\times 10^8\ m/s$

Now, we will use De Broglie's Equation to find out wavelength..

$\lambda =\frac{h}{mv}$

Where

$\lambda$ is the wavelength

$h$ is the Planck's constant $6.626\times 10^{-34}\ m^2\ kg / s$

$m$ is the mass in kg

$v$ is the speed in m/s

$\lambda=\frac{6.626\times 10^{-34}}{1.67 \times 10^{-27}\times 0.01\times 2.98\times 10^8}\\ \\\lambda=\frac{6.626}{1.67\times 0.01\times 2.98}\times 10^{-15}\\ \\\lambda=133.14\times 10^{-15}\ m\\\lambda=1.33\times 10^{-15}\ m$
