<span>1078 kgm / s would be the answer I hope this helps!!!</span>
So the acceleration of gravity is 9.8 m/s so that’s how quickly it will accelerate downwards. You can use a kinematic equation to determine your answer. We know that initial velocity was 19 m/s, final velocity must be 0 m/s because it’s at the very top, and the acceleration is -9.8 m/s. You can then use this equation:
Vf^2=Vo^2+2ax
Plugging in values:
361=19.6x
X=18 m
Answer/solution:
Given :
Mass =5kg
T 1 =20 C,T 2 =100 ∘C
ΔT=100−20=80 ∘C
Q=m×C×ΔT
where C= specific heat capacity of water
=4200J/(kgK)
Q=5×4200×80
=1680000 Joule.
=1680KJ
Answer: Kinetic theory or kinetic theory of gases attempts to explain overall properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion. The theory basically states that pressure is not caused by molecules pushing each other away, like earlier scientists thought.
Explanation:
Answer:
I = 2 MR²
Explanation:
Given that
Radius of the hollow ring ( hoop ) = R
The mass of the hoop = M
We know that mass moment of inertia of a hoop about its center is given as
Io= M R²
By using theorem ,mass moment of inertia at distance d from center is given as
I= Io + m d²
Here ,M= m ,d =R
Now by putting the values in the above equation we get
I = M R² + M R²
I = 2 MR²
Therefore the mass moment of inertia will be 2 M R².
