Describe how the structure of the kangaroo paw flower fits with a bird pollinator.

The final velocity of the Maserati after accelerating at the rate of 85 m/s² for 5 seconds is 431m/s.

From the first equation of equation of motion, final velocity is the sum of the initial velocity and the product of acceleration and time.

It is expressed as;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

Given the data in the question;

Plug the given values into the first equation of motion and solve for v.

v = u + at

v = 6m/s + ( 85m/s² × 5s )

v = 6m/s + 425ms/s²

v = 6m/s + 425m/s

v = 431m/s

The final velocity of the Maserati after accelerating at the rate of 85 m/s² for 5 seconds is 431m/s.

A drone starts from rest and travels 50m with an acceleration of 5 m/s2. it takes 4.5s.

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.

u= 0m/s

s = 50m

a = 5m/s²

t = ?

s = ut + 1/2 at²

50 = 0 + 1/2 * 5 * t²

t² = 50 *2/5

t² = 20s

v=u+at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

From the question

u = 10 m/s

a = 6 m/s²

t = 20 s

Substitute the values into the above formula and solve

That's

v = 10 + 6(20)

= 10 + 120

We have the final answer as

130 m/s

Velocity is the rate of change of displacement with time while acceleration refers to the rate of change of velocity with time.

Deceleration means the amount a speed or velocity decreases.

Velocity = displacement / time

Velocity is measured in m/s ( meters per second)

Acceleration = velocity / time and is measured in m/s2 ( meters per second square )

This also means that velocity differ from acceleration in that they have different unit as velocity is measured in m/s and acceleration is measured in m/s2

Velocity can simply be defined defined as the rate of change of velocity with time. It is a derived quantity. That is, a quantity which is obtained from the combination of one or more fundamental quantities. The units of derived quantities are called derived units.

So therefore, velocity is the rate of change of displacement with time while acceleration refers to the rate of change of velocity with time. Deceleration means the amount a speed or velocity decreases.

The Force of Gravitational Attraction is 34.85 ×10²¹N

Gravitational Force is the force acting between two masses separated by a distance. It is dependent on the magnitude of the masses and the distance between the two masses.

The mathematical relation is as follows:

F = Gm₁m₂/r²

where G is Gravitational Constant

m₁ is mass of first body

m₂ is mass of second body

r is the distance between the two masses

Given,

m₁ = 1.989×10³⁰

m₂ = 5.974×10²⁴

r = 1.5×10¹¹

G = 6.6×10⁻¹¹Nm²/kg²

On Substituting the above values,

F = 6.6×10⁻¹¹ × 5.974×10²⁴×1.989×10³⁰/(1.5×10¹¹)²

F = 34.85 ×10²¹N

When 68.5 g of sucrose is dissolved in 500.0 g of water, the freezing point of the water decreases by -0.744°C.

The correct option is C.

The temperature at which a liquid freezes is known as the freezing point. The freezing point normally rises with increased pressure, much like the melting point does. Combinations and some organic materials, such lipids, have freezing points that are lower than melting points.

The following formula is used to determine the freezing point depression:

ΔT = i m

where ,

ΔT is the change in freezing point,

i is the van't Hoff factor,

is the freezing point depression constant, and

m is the molality of the solution.

It is given in the question that the

of water = -1.86°C/mol

molar mass sucrose = 342.30 g/mol

i value of sugar = 1

500.0 g of water and 68.5 g of sucrose are dissolved in it.

ΔT  = 1 * -1.86° *m

molality = (68.5/342.3)/(500/1000)= 0.200116857/.5

m = 0.400

ΔT  = 1 * -1.86° * 0.400

a. The the smallest radius of curvature for the track that the train can tolerate is 4.44 km

b. The speed must the train mantain to keep the acceleration at the limit is 25 m/s

Using the equation for centripetal acceleration, we find the radius of the circle the train can tolerate.

So, centripetal acceleration a = v²/r where

Making r subject of the formula, we have

r = v²/a

Given that the train has a speed of 181 km/hr and its acceleration must not exceed 0.058g, we have that

So, substituting the values of the variables into the equation for r,we have

r ≥ v²/a

r ≥ (50.28 m/s)²/0.569 m/s²

r ≥ 2528.0784 m²/s²/0.569 m/s²

r ≥ 4443.02 m

r ≥ 4.44 km

So, the the smallest radius of curvature for the track that the train can tolerate is 4.44 km

Using the equation for centripetal acceleration, we find the radius of the circle the train can tolerate.

So, centripetal acceleration a = v²/r where

Making v subject of the formula, we have

v = √ar

Given that there is a curve of radius 1.100 km and its acceleration must not exceed 0.058g, we have that

So, substituting the values of the variables into the equation for r,we have

v = √ar

v = √(0.569 m/s² × 1100 m)

v = √(625.9 m²/s²)

v = 25.02 m/s

Area = M x M

Now, for Speed,

Speed = distance/time

unit of distance is Meter(M) and unit of time is Second(S), both of these are fundamental quantities.

Speed = Meter/second

Speed = M/S

Only when the average speed of the heavy particles is lower than that of the light particles will the average kinetic energy of the light particles equal the average kinetic energy of the heavy particles.

As the temperature rises, the particles accumulate kinetic energy and quicken. The actual average speed of the particles is influenced by both their mass and temperature; at a given temperature, larger particles travel more slowly than lighter ones.

Given that the formula for calculating a particle's kinetic energy is

Ek = 1/2 mu²,

The formula for particle speed is [tex]$$c = [3RT/M]^{1/2[/tex].
