You've definitely got the right idea and your procedure is correct.

But I see one mistake for sure, plus a few other things that
I'm not sure of.

The mistake for sure:  If the ending water is 12 ml,
then the beginning water is 9 ml, not 11 ml.

Things I'm not sure of:

-- I'm not sure that I'm remembering correctly at the moment,
but I have a sneaking hunch that you're supposed to read the
level at the BOTTOM of the meniscus, not the top.
It won't matter, because the DIFFERENCE will be the same
either way.  But if the teacher wants you to read from the bottom,
then your numbers may be marked wrong.

-- The question at the bottom asks for the "volume of cherry",
but I seem to see TWO cherries in the water.  Does than mean
they expect you to take only half of the displacement ?

-- They ask for "volume of cherry" twice.
Maybe that means they want you to end up with the volume in cm³
instead of ml.  (The number is the same.)

One student made the incomplete diagram shown below to represent the relationship between igneous rocks, sediments, sedimentary
Kryger [21]

Answer: Option (C)

Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.

  1. Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
  2. Sedimentary rocks are formed from the sedimentation and consolidation of sediments
  3. Igneous rocks are formed due to the crystallization of magma.

Hence the correct answer is option (C)

A) an electron has an initial speed of 226000 m/s. if it undergoes an acceleration of 4.0 x 1014 m/s2, how long will it take to
KIM [24]

initial speed of 226000 m/s

acceleration of 4.0 x 1014 m/s2,

speed of 781000 m/s

What is Acceleration?

  • Acceleration is a rate of change of velocity with respect to time with respect to direction and speed.
  • A point or an object moving in a straight line is accelerated if it speeds up or slows down.
  • Acceleration formula can be written as,

                    a = (v - u ) / t m/s²

As we have to find the time taken, the formula can be altered as,

t = \frac{v-u}{a}

where, t - time taken to reach a final speed

v - final velocity

u - initial velocity

a - acceleration.

Substituting all the given values,

t =\frac{781000 - 226000} {4* 1014}

= 1.3875 × 10⁻⁹ seconds.

So, taken to reach the final speed is found to be 1.3 × 10⁻⁹ 8iH..

A body is moving with a uniform acceleration of 2m/s² what does it mean?​
Nastasia [14]

Answer:

the body has energy due to its constant motion. it means it moves in a uniform acceleration which has zero velocity

Explanation:

Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.

an object is thrown off a cliff with intial pward velocity of 15m/s it strikes the ground with downward velocity of 25 m/s what
Genrish500 [490]

Answer:

20 m

Explanation:

Given:

v₀ = 15 m/s

v = -25 m/s

a = -10 m/s²

Find: Δy

v² = v₀² + 2aΔy

(-25 m/s)² = (15 m/s)² + 2 (-10 m/s²) Δy

Δy = 20 m
