Larry Finkelstein, Norman Fischer, and Cassius Schwartz have been overlooked, in my opinion.
Answer: The yellow light with a frequency equal to 5.21 x 1014 Hz will have a wavelength of E) 576 nm
A calorimeter measures the amount of heat in a chemical reaction. So the answer would be C, specific heat.
Answer:
∆h = 0.071 m
Explanation:
I rename angle (θ) = angle(α)
First we are going to write two important equations to solve this problem :
Vy(t) and y(t)
We start by decomposing the speed in the direction ''y''
Vy in this problem will follow this equation =
where g is the gravity acceleration
This is equation (1)
For Y(t) :
We suppose yi = 0
This is equation (2)
We need the time in which Vy = 0 m/s so we use (1)
So in t = 0.675 s → Vy = 0. Now we calculate the y in which this happen using (2)
2.236 m is the maximum height from the shell (in which Vy=0 m/s)
Let's calculate now the height for t = 0.555 s
The height asked is
∆h = 2.236 m - 2.165 m = 0.071 m
<span>What role did gravity play in the formation of the planets?
A.
Gravitational forces brought together several moon-sized bodies, called
planetesimals, to form larger bodies that became planets.</span>
