The answer is either harmonic motion or simple harmonic motion.
Physical changes do not change the identity of the substance. Heat causes chemical reactions. You cannot see chemical changes with the naked eye. The identity of a substance changes like when you burn paper, from paper it turns into ash and produces smoke, which are products from the chemical reactions.
The product of wavelength and frequency is always the
speed of the wave.
For this particular wave,
Speed = (2 meters) x (6 per second) = 12 meters per second .
Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile,
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :
Substituting all the values in above formula. So, we get :
d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
That's false. Displacement would be (r2 - r1) .
