Answer:
solution:
when the engine are fired the rocket has a linear constant acceleration motion:
is the final velocity of the rocket
when the engines are fired it become equal to the initial velocity of the rocket,
<em>when the engines are shut off</em>
<em></em><em></em>
solve eq(1) and eq(2) we find
solving for =364.65 m
Where is the distance travelled by the rockets for shutting off the engine
<em>when the engines are fired:</em>
<em></em><em></em>

The total circuit current at the resonant frequency is 0.61 amps
What is a LC Circuit?
- A capacitor and an inductor, denoted by the letters "C" and "L," respectively, make up an LC circuit, also referred to as a tank circuit, a tuned circuit, or a resonant circuit.
- These circuits are used to create signals at particular frequencies or to receive signals from more complicated signals at particular frequencies.
Q =15 = (wL)/R
wL = 30 ohms = Xl
R = 2 ohms
Zs = R + jXl = 2 +j30 ohms where Zs is the series LR impedance
| Zs | = 30.07 <86.2° ohms
Xc = 1/(wC) = 30 ohms
The impedance of the LC circuit is found from:
Zp = (Zs)(-jXc)/( Zs -jXc)
Zp = (2+j30)(-j30)/(2 + j30-j30) = (900 -j60)2 = 450 -j30 = 451 < -3.81°
I capacitor = 277/-j30 = j9.23 amps
I Zs = 277/(2 +j30) = (554 - j8,310)/904 = 0.61 - j9.19 amps
I net = I cap + I Zs = 0.61 + j0.04 amps = 0.61 < 3.75° amps
Hence, the total circuit current at the resonant frequency is 0.61 amps

Answer:
104.3 cm or 179.7
Explanation:
First find time that it takes for the object to hit the ground
*
Then find xf of projectile
not 100% sure if the projectile is going away from the object or towards it but you either do 142- 37.7 or 142+37.7
hope that helps

Answer: c) it determines the timing of seasons and the length of the year </h2><h2 />
Explanation:
The revolutions of the Earth (also called translation movement), consist of <u>the elliptical orbit that describes the Earth around the Sun. </u>
In this sense, a complete revolution around the Sun occurs every 365 days, 5 hours, 48 minutes and about 46 seconds. It is thanks to this movement and that the Earth's axis is tilted with respect to the plane of its orbit about , that the four seasons of the year exist.
For this reason, some regions receive different amounts of sunlight according to the seasons of the year. These variations are more evident near the poles and softer or imperceptible in the tropics (near the equator). Because near the equator the temperature tends to be more stable, with only two seasons: rain and drought.
Explanation:
The given data is as follows.
Speed of the bullet (v) = 500 m/s
Distance during one RC time constant (d) = 1 mm =
Capacitance (C) = 600 =
Hence, formula for speed of the bullet is as follows.
v =
or, t =
Time constant for RC circuit is as follows.
t = RC
R =

=
=
Thus, we can conclude that resistance in the flash tube is .
