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

I need help on number 5. We need to use one of the four kinematics equations.

Gnom [1K]

ANSWER

$35.02m$

EXPLANATION

Parameters given:

Initial velocity, u = 26.2 m/s

When the vase reaches its maximum height, its velocity becomes 0 m/s. That is the final velocity.

We can now apply one of Newton's equations of motion to find the height:

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

where a = g = acceleration due to gravity = 9.8 m/s²

Therefore, we have that:

$\begin{gathered} 0=26.2^2-2(9.8)s \\ \Rightarrow19.6s=686.44 \\ s=\frac{686.44}{19.6} \\ s=35.02m \end{gathered}$

That is the height that the vase will reach.

Is visible light a form of<br> radiation? Explain.

natali 33 [55]

Answer:

Yes,in fact visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets', called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).

The spin-drier of a washing machine revolving at 900.RPM slows down uniformly to 300.RPM while making 60. revolutions. Find the

jeyben [28]

<h2>Answer:</h2>

<u>Acceleration is </u><u>-10.57 rad/s² </u>

<u>Time is </u><u>6 seconds</u>

<h2>Explanation:</h2><h3>a) </h3>

u=900rpm= 94.248 rad/s

v =300rpm= 31.416 rad/s

s=60 revolutions= 377 rad

v²= u²+ 2as

31.416² = 94.248²+ 2 * a * 377

a = v²-u² / 2s

a= -10.57 rad/s²

Using 1st equation of motion

v-u/a = t

Putting the values

t = (31.4 - 94.2)/-10.57

t = 6 seconds
