the water specific heat will remain at 4.184.
The equation that relates distance, velocities, acceleration, and time is,
d = V₀t + 0.5gt²
where d is distance,
V₀ is the initial velocity,
t is time, and
g is the acceleration due to gravity (equal to 9.8 m/s²)
(1) Dropped rock,
(3 x 10² m ) = 0(t) + 0.5(9.8 m/s²)(t²)
The value of t from this equation is 24.73 s
(2) Thrown rock with V₀ = 26 m/s
(3 x 10² m) = (26)(t) + 0.5(9.8 m/s²)(t²)
The value of t from the equation is 5.61 s
The difference between the tim,
difference = 24.73 s - 5.61 s
difference = 19.12 s
<em>ANSWER: 19.12 s</em>
The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:
Answer:
Explanation:
Let assume that ball's motion is frictionless and its geometric dimensions can be neglected. Besides, it is assumed that ball begins at a height of zero. The ball can be modelled by means of the Principle of Energy Conservation:
The initial speed of the ball is:
When something is plumb, it means it's straight up and down. If a post installed in flat ground is leaning in any direction, it's out of plumb. If it's at a 90-degree angle to the ground on all sides, it's plumb. To be plumb is to be parallel with the force of gravity.
