Answer:5000000000hertz
Explanation:
Wavelength=6cm=6/100 m=0.06m
Frequency=velocity/wavelength
Frequency=(3×10^8)÷0.06
Frequency=5000000000 hertz
Answer:
Explanation:
<u>Free Fall Motion
</u>
If an object is dropped from a certain height h in free air (no friction), it falls to the ground with an acceleration of gravity (). The speed of the object is given by
And the distance traveled downwards is
We can find the time the object is in the air before reaching ground level, solving the above equation for t as follow
Now we compute the speed
We have:
Total Energy: KE + GPE
KE (Kinetic Energy) =
GPE (Gravitational Potential Energy) =
Data:
m (mass) = 2.0 Kg
v (speed) = 10 m/s
h (height) = 50 m
Use: g (gravity) = 10 m/s²
Formula:
Total Energy: KE + GPE
Solving:
If an object is given an initial velocity in any direction and then allowed to travel freely under gravity only, it is called a projectile motion.
It is basically 3 types
- horizontally projectile motion
- oblique projectile motion
- included plane projectile motion
The path followed by a projectile is called its trajectory.
Answer:
the changes in waves
Explanation:
the moon has its own gravitational pull thus making waves and the rising tides
