<span>In assumption that there were two scientists who used
different measurement systems in their research. The problems that might arise
if they shared their data is obviously and primarily error. Errors are
recognized and one element in every measure, system and quantity. Error was
already even present in the measurement system alone a scientist used and it
will furthermore aggregate, when these two different scales are combined the
more error escalates in the process. There are two types: random and systematic
error. </span>
Answer: The block of 0.4 Kg travel the same distance that the block of
0.2 Kg
Explanation: Considering the second newton law, we have the following
F= m*a
F= P*sin (θ) where θ is the angle for the incline
so mg sin (θ)= m*a
a=g sin(θ)
both block have the same acceleration in the inclined plane so travel the same distance independent of its mass.
Answer: ![36.86\°](https://tex.z-dn.net/?f=36.86%5C%C2%B0)
Explanation:
According to the described situation we have the following data:
Horizontal distance between lily pads: ![d=2.4 m](https://tex.z-dn.net/?f=d%3D2.4%20m)
Ferdinand's initial velocity: ![V_{o}=5 m/s](https://tex.z-dn.net/?f=V_%7Bo%7D%3D5%20m%2Fs)
Time it takes a jump: ![t=0.6 s](https://tex.z-dn.net/?f=t%3D0.6%20s)
We need to find the angle
at which Ferdinand jumps.
In order to do this, we first have to find the <u>horizontal component (or x-component)</u> of this initial velocity. Since we are dealing with parabolic movement, where velocity has x-component and y-component, and in this case we will choose the x-component to find the angle:
(1)
(2)
(3)
On the other hand, the x-component of the velocity is expressed as:
(4)
Substituting (3) in (4):
(5)
Clearing
:
![\theta=cos^{-1} (\frac{4 m/s}{5 m/s})](https://tex.z-dn.net/?f=%5Ctheta%3Dcos%5E%7B-1%7D%20%28%5Cfrac%7B4%20m%2Fs%7D%7B5%20m%2Fs%7D%29)
This is the angle at which Ferdinand the frog jumps between lily pads
Answer:
4 hoop, disk, sphere
Explanation:
Because
We are given data that
Hoop, disk, sphere have Same mass and radius
So let
And Initial angular velocity, = 0
The Force on each be F
And Time = t
Also let
Radius of each = r
So let's find the inertia shall we!!
I1 = m r² /2
= 0.5 mr² the his is for dis
I2 = m r² for hoop
And
Moment of inertia of sphere wiil be
I3 = (2/5) mr²
= 0.4 mr²
So
ωf = ωi + α t
= 0 + ( τ / I ) t
= ( F r / I ) t
So we can see that
ωf is inversely proportional to moment of inertia.
And so we take the
Order of I ( least to greatest ) :
I3 (sphere) , I1 (disk) , I2 (hoop) , ,
Order of ωf: ( least to greatest)
That of omega xf is the reverse of inertial so
hoop, disk, sphere
Option - 4
The piece of evidence that suggests that the inner planets were formed from the same rotating cloud of gas and dust is that the planets orbit the sun in the same direction and in the same plane
Smaller planets like Mercury, Venus, Earth, and Mars are considered inner planets. Mercury is thought to be the smallest inner planet, with Earth being the largest. The vastly larger outer planets, such as Jupiter, Saturn, Uranus, and Neptune, are the opposite.
A route that an object or planet in space follows around another body is referred to as an orbit. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.
