I don’t understand the question I’m really sorry:/.
Answer:
A galaxy with a disk and central bulge like a spiral galaxy, but with no spiral arms
Explanation:
A Lenticular galaxy is a kind of galaxy intermediate between elliptical galaxy and a spiral galaxy in the Morphological classification system of galaxies. They have a central bulge or disc just like a Spiral galaxy but lacks the arms of spiral galaxy. If looked edge on they appear to be spiral and if looked face on they appear to be elliptical.
The absence of spiral arms can be attributed to the absence of star formation. They mainly consists of ageing stars.
<span>A spring balance will give a different mass reading on the Moon from that on Earth. A beam balance however, will give the same reading.Explain why.
</span>
<span>Beam Balance:
Beam balance measures mass.
Mass is the amount of matter the object has.
The S.I. unit of mass is kg
</span><span>
Spring Balance:
Spring balance measures weight not mass.
Disadvantage: It requires gravity to measure.
The S.I. unit of weight is newton (N).
That is why when we are in outer space, we become lighter-there is less gravity!</span>
Mass remains constant while weight is dependent on the gravitational pull of the planet. Mass only changes with a change in matter that results in a change of volume.
<span>Mass remains constant throughout. Only weight changes with gravitational acceleration. Mass will only change with a change in the volume of matter in the body.</span>
Answer:
Explanation:
Given
initial angular velocity is
when motor is turned of it started decelerating with angular acceleration
angle turned before coming to halt
here final angular velocity is zero
No of revolutions will be
Answer:
Explanation:
The bicycle wheel can be modeled as a hoop, which moment of inertia is:
(1) Where is the mass and is the radius.
However, since we are given the applied force and angular acceleration , we can use the following equation:
(2)
Where:
Isolating :
(3)
(4)
Finally:
This is the bicycle wheel moment of inertia
