Thanks Bruv

Explanation:

There's a baked potato on a chair

My mother was just sitting there

I thought I heard her in this room

Theres only one thing to assume

My mom has turned into a baked potato

I'm pretty sure potato transformations are fatal

The potato expert will be here soon

But he's just some scrawny Irish dude

My mom has turned into a baked potato

This saucer is wearing a wizard hat

Oh my God she's been cursed by a saucer-er

Hold on a minute is that my dad

My dad has been turned into a mashed potato and I think this one is medically worse

He was my favorite patriarch but now he's just a patri-staaaaaaarch

When a ball is launched from the ground at a 45° angle to the horizontal, it falls back to the ground 50 m from the launch point

Inessa [10]

Answer:

Explanation:

Given

angle through which ball is launched $=45^{\circ}$

Range of ball=50 m

Range of projectile is $=\frac{u^2sin2\theta }{g}$

$50=\frac{u^2sin90}{9.8}$

u=22.136 m/s

If ball is thrown straight upward

$v^2-u^2=2as$

$0-(22.136)^2=2(-9.8)s$

$s=\frac{22.136^2}{2\times 9.8}$

s=25 m

(b)For Projectile time of flight is

$t=\frac{2usin\theta }{g}$

$t=\frac{2\times 22.136\times sin45}{9.8}$

t=3.19 s

If the relative humidity is 25 nd the saturation mixing ratio is 24g/kg, what is the mixing ratio?

levacccp [35]

The mixing ratio is 6.

To find the answer, we have to know about the mixing ratio.

<h3>What is mixing ratio?</h3>

The mixing ratio must be calculated in a complex manner.
A saturated vapor pressure (es) for values of air temperature and an actual vapor pressure (e) for values of dewpoint temperature must be determined in order to determine the mixing ratio.
The air temperature and/or dewpoint temperature must first be converted to degrees Celsius (°C) before the vapor pressures can be calculated.
The equation below can be used to determine the relative humidity (rh), as well as the actual mixing ratio and saturated mixing ratio,

$Rh=\frac{w}{w_s} *100$
