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''

$sin(\alpha) = \frac{Vyi}{Vi}$

$Vyi = Vi.sin(\alpha ) = 9.2 \frac{m}{s} .sin(46) = 6.62 \frac{m}{s}$

Vy in this problem will follow this equation =

$Vy(t) = Vyi -g.t$

where g is the gravity acceleration

$Vy(t) = Vyi - g.t= 6.62 \frac{m}{s} - (9.8\frac{m}{s^{2} }) .t$

This is equation (1)

For Y(t) :

$Y(t)=Yi+Vyi.t-\frac{g.t^{2} }{2}$

We suppose yi = 0

$Y(t) = Yi +Vyi.t-\frac{g.t^{2} }{2} = 6.62 \frac{m}{s} .t- 4.9\frac{m}{s^{2} } .t^{2}$

This is equation (2)

We need the time in which Vy = 0 m/s so we use (1)

$Vy (t) = 0\\0=6.62 \frac{m}{s} - 9.8 \frac{m}{s^{2} } .t\\t= 0.675 s$

So in t = 0.675 s → Vy = 0. Now we calculate the y in which this happen using (2)

$Y(0.675s) = 6.62\frac{m}{s}.(0.675s)-4.9 \frac{m}{s^{2} } .(0.675s)^{2} \\Y(0.675s) =2.236 m$

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

$Y(0.555s)= 6.62 \frac{m}{s} .(0.555s)-4.9\frac{m}{s^{2} } .(0.555s)^{2} \\Y(0.555s) = 2.165m$

The height asked is

∆h = 2.236 m - 2.165 m = 0.071 m

A blackbody curve relates the wavelength of emitted light to _____. intensity color frequency speed

Kitty [74]

The best answer would be intensity. A black body curve relates to the wavelength of the emitted light to its intensity. To expands the thought, the curve is referring to the power that is being transferred per unit area.

I'm thinking it's a parabola since you can cover a vast amount of apace within the parabola too.

What is satellite ?

An object that has been placed into orbit in space on purpose is known as a satellite or artificial satellite. Except for passive spacecraft, most satellites feature a power generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs) (RTGs). Most satellites also include a mechanism of communicating to ground stations, called transponders. The most common satellites, small CubeSats, use a standardized bus to reduce costs and labor. Satellites of a similar type can cooperate with one another to form constellations. Satellites are made to be as light and durable as possible due to the high cost of space launch. Satellites are launched into orbit from the surface by vehicles that are high enough to prevent orbital decay caused by the atmosphere.
