A projectile is fired straight upward at 173 m/s. how fast is it moving at the instant it reaches the top of its trajectory?

Fittoniya [83]

The top of the trajectory is the point where it changes from rising to falling. At that exact instant, its vertical speed is zero.

an oscilloscope has a time/div setting of 50ms and there are 10 divisions on the time scale. a sine wave on the oscilloscope dis

Answer:

The frequency is f = 6Hz

Explanation:

Given

The time division setting is $d_t =50ms = 50*10^{-3}s$

The number of division is $n= 10$

The total time for 10 division can be mathematically obtained as

$T_{total} = 10 *50*10^{-3}$

$=500 *10^{-3}s$

From the question the time for 3 cycle is

$T_{total} = 500*10^{-3}s$

Then the for one cycle which equivalent to the Period $(T)$ $= \frac{T_{total}}{3}$

$= \frac{500 *10^{-3}}{3}$

The frequency is generally given as $f = \frac{1}{period} = \frac{1}{T}$

Now substituting values we have

$f = \frac{3}{500 *10^{-3}}$

$= 6Hz$

The different types of energy transfers are convection, conduction, and radiation.
I'm not too sure on the second one but thermodynamics relates thermal energy, kinetic energy, and potential energy. I'm basing this on the formulas of the laws of thermodynamics, but it could also be temperature, heat, or work.
