Answer:

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

Answer:

t = 1.659s

Explanation:

We can use the kinematics equations to solve this questions:

v = u + at

v^{2} = u^{2} +2as

where v = Final Velocity, u = initial velocity, a = acceleration, t = time, s = displacement

a) Given information from the question,

u = \frac{70km}{h} =\frac{(70*1000)m}{(1*3600)s} = 19.444m/s (Convert km/h to m/s first)

a = 2m/s^{2}

s = 35m

Now we can substitute these values into the 2nd kinematics equation to find v, final velocity.

v^{2} =(19.444)^{2} +2(2)(35)\\v=\sqrt{(19.444)^{2} +2(2)(35)} \\v= 22.761m/s (5.sf)\\

b) Now we have the final velocity, we can substitute the values into the first kinematics equation to find t , the time taken.

v = u + at

22.761 = 19.444 + 2t

2t = 22.761 - 19.444

t =\frac{22.761-19.444}{2}

t = 1.659s

The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms
aalyn [17]

The question to the above information is;

What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?

Answer;

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

Explanation;

-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.

J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:

  • atoms are spheres of positive charge
  • electrons are dotted around inside

Sherlock Holmes examines a clue by holding his magnifying glass (with
Alborosie

Answer:

Distance: -30.0 cm; image is virtual, upright, enlarged

Explanation:

We can find the distance of the image using the lens equation:

\frac{1}{f}=\frac{1}{p}+\frac{1}{q}

where:

f = 15.0 cm is the focal length of the lens (positive for a converging lens)

p = 10.0 cm is the distance of the object from the lens

q is the distance of the image from the lens

Solving for q,

\frac{1}{q}=\frac{1}{f}-\frac{1}{q}=\frac{1}{15.0}-\frac{1}{10.0}=-0.033\\q=\frac{1}{0.033}=-30.0 cm

The negative sign tells us that the image is virtual (on the same side of the object, and it cannot be projected on a screen).

The magnification can be found as

M=-\frac{q}{p}=-\frac{-30}{10}=3

The magnification gives us the ratio of the size of the image to that of the object: since here |M| = 3, this means that the image is 3 times larger than the object.

Also, the fact that the magnification is positive tells us that the image is upright.

At 7:00 pm the police discovered a body in a hotel room which maintained a constant temperature of 24 degree C. At the time of d
schepotkina [342]

Explanation:

According to Newton's law of cooling,

T(t)=T_s+(T_o-T_s){e^{{-t/\tau}}

T(t) is the temperature at time t

T_s is temperature of surrounding

k=\dfrac{1}{\tau}

At the time of discovery, the temperature of the dead body was, T_o=36^{\circ}C

Temperature of the surrounding, T_s=24^{\circ}C

Temperature after 4 hours, T=30^{\circ}C

So, 30=24+(36-24)e^{-4t}

On solving the above equation,

k = 0.1735

Now, put the value of k in equation (1) at T = 36 degrees C

We know that, the temperature of body before death is T(t) = 37 degrees C

37=24+(36-24)e^{0.17t}

On solving above equation,

t = -0.46 hour

As time can't be negative and we have taken 7:00 pm as reference time.

So, t = 27.67 minutes

So, the death of the person is at 6 : 32 pm. Hence, this is the required solution.

James is trying to prove Newton's 2nd law of motion. He tries to move four different objects with different masses from point A

Toy car will take the least amount of force.
this is because the toy car has a much lighter mad than the other objects meaning it will take less force to get it to move.
