Without the metric system, we'd have a different International System of Units, the metric system is important because 1mm is 0.1cm, 1 cm is 0.01m, with the imperial system the conversion is tedious. The most important feature of the metric system is its base in scientific fact and repeatable standards of measurement

Answer:

0.8 m/s

Explanation:

From the question,

MV = mv............................. Equation 1

Where M = mass of the cannon, m = mass of the cannonball, V = velocity of the cannon, v = velocity of the cannon ball.

make V the subject of the equation

V = mv/M........................ Equation 2

Given: m = 2 kg, M = 500 kg, v = 200 m/s

Substitute these value into equation 2

V = (2×200)/500

V = 400/500

V = 0.8 m/s

Or between hydrogen and carbon (two atoms with very similar electronegativities) the bond energy is about 98 kcal. The larger the bond energy, the higher the amount of external energy it will take to pull the atoms apart, and thus the stronger the force holding the atoms together.

People are fascinated with high-speed travel. A Boeing 747 flies at about 550 miles per hour. The Concorde Supersonic Transport flew over twice as fast at about 1350 miles per hour. That is impressively fast, but consider the speeds that we passengers on planet Earth always travel. The circumference of the Earth at the equator is 24900 miles and the residents of the tropic areas travel that distance every 24 hours. They are traveling over a thousand miles an hour. At 38° latitude we are traveling about 820 miles per hour. That is quite impressive but it pales in comparison with the orbital speed of the Earth, The average distance of the Earth from sun is 93.5 million miles. This means that in 365.25 days the Earth travels 587.5 million miles. This works out to about 67 thousand miles per hour. This is the speed we travel 24 hours a day, 365.25 days a year.

The orbital velocity is 2πR/T where R is the average radius of the orbit and T is the length of the year. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year.

A. The fossils cam from the same organism

Hope this helps!

The fossils came from the same organism. This conclusion is most reasonable.

A fossil is an item that has survived in the Earth's crust as a remnant, impression, or trace of an extinct animal or plant. The main repository for knowledge regarding the evolution of life on Earth is the complex of information preserved in fossils found all across the world.

Fossils of dinosaurs discovered in Alberta, Canada. Only a small percentage of extinct species have been preserved as fossils, and often only those with a sturdy skeleton are capable of doing so. A calcareous skeleton or shell is present in the majority of major groups of invertebrate creatures (e.g., corals, mollusks, brachiopods, bryozoans). Other types have silicon dioxide or calcium phosphate shells (both of which are found in the bones of vertebrates).

Answer is:

A:The movement of large land areas across earth's surface

Answer:

F = 120 N

Explanation:

Given that,

The mass of a runner, m = 60 kg

Acceleration of the runner, a = 2 m/s²

We need to find the force provided from her legs. The formula for force is given by :

F = ma

Substitute all the values,

F = 60 kg × 2 m/s²

= 120 N

So, the required force is equal to 120 N.

Given:

Mass,

Acceleration,

As we know that,

→ [tex]Force = Mass\times Acceleration[/tex]

or,

→ [tex]F = ma[/tex]

then,

      [tex]= 60\times 2.0[/tex]

      [tex]= 120\ N[/tex]

Given that,

Time taken to reach the ground, t = 7 s

We need to find the height of the cliff. We can find it using second equation of kinematics as follows :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

Here,

u = 0 (at rest initially)

a = g

So,

[tex]h=\dfrac{1}{2}gt^2\\\\h=\dfrac{1}{2}\times 9.8\times 7^2\\\\h=204.1\ m[/tex]

So, the cliff's height is 204.1 m.

if your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts

Newton’s 1st Law of Motion is the motion of an object remains the same unless it is acted upon by a force.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

If your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts.

Easy the answer to your question is Obviously "A"

Answer:

d.

Explanation:

Since the dart's initial speed v at angle has both vertical and horizontal components v₀sinθ and v₀cosθ respectively, the vertical component of the speed continues to decrease until it hits the target. It's displacement ,s is gotten from

s = y - y₀ = (v₀sinθ)t - 1/2gt² where y₀ = 0 m

y - 0 = (v₀sinθ)t - 1/2gt²

y = (v₀sinθ)t - 1/2gt²

which is the parabolic equation for the displacement of the dart.

Note that the horizontal component of the dart's velocity does not change during its motion.

Since the target falls vertically, with initial velocity u = 0 (since it was stationary before the string cut), it's displacement ,s' is gotten from

s' = y - y₀' = ut - 1/2gt² where y₀' = initial height of target above the ground

= (0 m/s)t - 1/2gt²

= 0 - 1/2gt²

y - y₀' = - 1/2gt²

y = y₀' - 1/2gt²

which is the parabolic equation for the displacement of the target.

The equation for both the displacement of the dart and the target can only be gotten if we considered vertical motion. So, the displacement component of both the dart and target are both vertical.

So, the answer is d.

Answer:

The rotation period and revolution period of moon is same.

Explanation:

Because,The moon keeps the same face pointing towards the Earth bcoz it's rate of spin is tidally locked so that it is synchronised with it's rate of revolution.

Therefore it's rotation and revolution period is once about every 27 days.

Fick's law of diffusion states that the rate of diffusion is directly proportional to the concentration gradient, and the surface area and inversely proportional to the membrane's thickness

The differences expected are;

The reasons why the above expected differences are correct are as follows:

Diffusion that is time dependent is given by the following equation based on the fluctuation-dissipation theorem;

D(t) = μ·[tex]k_B[/tex]·T·(1 - [tex]e^{-t/(m\cdot \mu )}[/tex])

Where;

μ = The particle mobility

[tex]k_B[/tex] = Boltzmann's constant

T = The temperature in Kelvin

m = The mass of the particle

t = The time

Therefore, the rate of diffusion is directly proportional to the  temperature, given that the substances have the same molecular masses

The differences to expect if, at the same time you place a yellow and blue food coloring in both hot and cold water is that;

The rate of diffusion of the food coloring will be faster when placed in the hot water, due to the higher kinetic energy (moving faster) of the liquid particles to which the coloring is added, such that the differences are as follows;

Diffusion of the coloring is more evenly spread and at a faster rate when either the yellow or blue food coloring is placed in HOT water than when placed in COLD water

Answer:

light in the UV range.

Explanation:

Noble gases and halogens can combine to form lasers called Excimer, for this to happen the noble gas must be ionized with a high voltage discharge, thus forming a molecule of the type

      noble gas (X) + halogen (H) → XH

This molecule is highly unstable and decomposes within a few nanoseconds, emitting light in the UV range.

The light from one gas is different from light of other gases such that they are

highly unstable.

Noble gases are also referred to as inert gases which form lasers under

some conditions.The lasers are formed when the noble gas undergo

ionization with a high voltage discharge.

The high instability and high decomposition rate which occurs within a few

nanoseconds emits light in the UV range thereby giving rise to them being

Answer:

Explanation:

When the object falling attains terminal velocity , net force on it becomes zero. That means drag force becomes equal and opposite to its weight.

So drag force = mg

where m is mass of falling body and g is acceleration due to gravity .

The drag force is constant . It is doing work against the weight of falling body . Object is falling v m /s . That means drag force is doing work per second as follows

Work done per second = force x displacement per second

= mg x v

So

Power of drag force = mgv.

Pd = mgv.
