Answer:
90 km/h
Explanation:
we just divide the distance by the time to get the speed.
Ek = 6KJ.
In physics, the kinetic energy of a body or object is the one that owns due to its movement and is given by the equation , where m is the mass of the object in kilograms and v is the velocity in m/s.
An object that it has a mass of 30 kilograms and moves with a velocity of 20m/s, its kinetic energy is given by:
Stop with that link need to stop
Answer:
Explanation:
Condensing is the word used to indicate the change of state of a substance from vapor to liquid, as in this case. During condensation, the substance releases thermal energy to the environment, therefore the kinetic energy of the molecules in the vapor decreases until they become closer to each other and they start to be affected by the intermolecular forces and so the substance becomes a liquid.
Explanation:
The wave equation which is propagating down a string of unknown material is given by :
................(1)
The general equation of wave is given by :
..............(2)
Comparing equation (1) and (2) we get:
(a)
f = 0.954 Hz
(b) Radian frequency,
(c) k = 7
(d) Wave number,
(e) Speed of sound,
v = 0.849 m/s
Hence, this is the required solution.
