Answer:
Triples
Explanation:
Kinetic energy =1/2 mv^2 + 1/2 Iw^2
v= linear velocity
w= angular velocity
I= moment of inertia of object
I = k mr^2 where k is a constant for a particular shaped object
v = rw
w=v/r
Rotational Kinetic energy = 1/2 k m× (v/r)^2 × r^2
Total Kinetic energy = translational Kinetic energy + rotational Kinetic energy
KE = 1/2 (1+k) mv^2
Centripetal acceleration = mv^2/r
When KE is tripled, because 1/2(1+k) is a constant for a particular object, mv^2 part gets tripled. r doesn't appear in the equation of total Kinetic energy. So tripling Kinetic energy doesn't affect r. Therefore centripetal acceleration also gets tripled.
There would be a high amount of dead matter
1 litre = 1000 Milliliters is the answer
1 m^3 = 1000 litres
Answer:
The answers to your questions are given below
Explanation:
22. The energy of an electromagnetic wave and it's frequency are related by the following equation:
E = hf
Where:
E => is the energy
h => is the Planck's constant
f => is the frequency
From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.
23. Gamma ray and radio wave are both electromagnetic waves. All electromagnetic waves has a constant speed of 3×10⁸ m/s in space.
Thus, gamma ray and radio wave have the same speed in space.
