Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
Simple theory.
Metallic and non-metallic
Hope this helps!
Answer:
The linear velocity is
Explanation:
According to the law of conservation of energy
The potential energy possessed by the hoop at the top of the inclined plane is converted to the kinetic energy at the foot of the inclined plane
The kinetic energy can be mathematically represented as
Where is the moment of inertia possessed by the hoop which is mathematically represented as
Here R is the radius of the hoop
is the angular velocity which the hoop has at the bottom of the lower part of the inclined plane which is mathematically represented as
Where v linear speed of the hoop's center of mass just as the hoop leaves the incline and rolls onto a horizontal surface
Now expressing the above statement mathematically
=>
=>
=>
=>
Substituting values
Answer:
It will take the system 0.63sec to complete one full oscillation
Explanation:
The expression for period of a body in simple harmonic motion is
T=2*pi√m/k
Where T Is the period
m is the mass of the body
K is the spring constant
Given data
m = 7.5kg
e=15cm
k=750j/m2
Substituting our data into the expression
T=2*3.142 √ 7.5/750
T=6.284*0.1
T=0.63sec
Answer:
yes
Explanation:
By definition, the speed of an object is the rate of change of its position.Velocity, on the other hand, is the measurement of the rate and direction of change in the position of an object. Since it is a vector physical quantity, both magnitude and direction are required to define it
