dens = mass/volume. after crushing, vol less so density more. the actual density of the metal is the same, density of can changes
On comparing values , we see that student which has the largest percent error is <u>A. Student 4: 9.61 m/s2
.</u>
<u>Explanation:</u>
Here, we have Four students measured the acceleration of gravity. The accepted value for their location is 9.78m/s2. Let's calculate which student’s measurement has the largest percent error :
<u>A. Student 4: 9.61 m/s2
</u>
Percentage of error = %.
<u>B. Student 3: 9.88 m/s2
</u>
Percentage of error = %.
<u>C. Student 2: 9.79 m/s2
</u>
Percentage of error = % .
<u>D. Student 1: 9.78 m/s2</u>
Percentage of error = % .
On comparing values , we see that student which has the largest percent error is <u>A. Student 4: 9.61 m/s2
.</u>
Answer:
The circumference will be "43,200 km".
Explanation:
As you should be directly south of Tyene, this same angular distance among both yourself as well as the town of Tyene seems to be the distinction to be made throughout the height including its sun at two positions on a specified day.
The sun is therefore immediately overhead in Tyene, does have an altitude with respect to the horizon will be:
⇒
At the very same day on yourself location, the altitude of the sun will be:
⇒
Therefore, a complete circle is 360 degrees. So the angular distinction will be somewhere between you as well as Tyene:
⇒
Therefore,
⇒
⇒
If,
Now,
The circumference =
=
Answer:
22m/s
Explanation:
Mass, m=60 kg
Force constant, k=1300N/m
Restoring force, Fx=6500 N
Average friction force, f=50 N
Length of barrel, l=5m
y=2.5 m
Initial velocity, u=0
Substitute the values
m
Work done due to friction force
We have
Substitute the values
Initial kinetic energy, Ki=0
Initial gravitational energy, \
Initial elastic potential energy
Final elastic energy,
Final kinetic energy,
Final gravitational energy,
Final gravitational energy,
Using work-energy theorem
Substitute the values
