The answer is D because water has less kinetic energy so the particles stay closer together
Answer:
Option D.) 5.0 x 10^-4m
Explanation:
Data obtained from the question include:
f (frequency) = 6 x 10^11 Hz
v (velocity) = 3.00 x 10^8 m/s
λ (wavelength) =?
Using the equation v = λf, the wavelength can be obtained as illustrated below:
v = λf
λ = v/f
λ = 3.00 x 10^8/6 x 10^11
λ = 5 x 10^-4m
Therefore, the wavelength of the beam of the electromagnetic radiation is 5 x 10^-4m
Answer:
Explanation:
Consider the initial position of the frog (20 m above ground) as the reference position. All measurements are positive measured upward.
Therefore,
u = 10 m/s, initial upward velocity.
H = - 20 m, position of the ground.
g = 9.8 m/s², acceleration due to gravity.
Part (a)
When the frog reaches a maximum height of h from the reference position, its velocity is zero. Therefore
u² - 2gh = 0
h = u²/(2g) = 10²/(2*9.8) = 5.102 m
At maximum height, the frog will be 20 + 5.102 = 25.102 m above ground.
Answer: 25.1 m above ground
Part (b)
Let v = the velocity when the frog hits the ground. Then
v² = u² - 2gH
v² = 10² - 2*9.8*(-20) = 492
v = 22.18 m/s
Answer: The frog hits the ground with a velocity of 22.2 m/s
Answer: Inertia
Explanation: Objects to stay in motion or at rest unless there is an external unbalanced force aced upon the object.
