Explanation:

The correct answer is A. He created a way of naming organisms based on genus and species

Explanation:

Carl Linnaeus created a simple but precise system for naming organisms of any species and kind. This system was known as binomial nomenclature and the names of organisms depend on two main elements: the genus and the species. The first element is a broad category that covers species with a common origin, and the second one is the species, which describes organisms that can reproduce and share many common features including DNA sequence. According to this, the correct answer is A.

Answer:

Explanation:

Using the formula : E = mc²

Where m = mass = 6.8 × 10^-6 kg

c = speed of light = 3 ×10^8 m/s

The amount of joules of energy that would be produced equals :

Plugging in our values :

E = mc²

E = (6.8 × 10^-6) kg × (3 ×10^8)²m/s

E = (6.8 × 10^-6) kg × 9 × 10^16 m/s

E = 61.2 × 10^(-6 + 16)

E = 61.2 × 10^10 J

Answer:

E = 6.12 × 1011 kg × m2/s2

Answer:

From what I see, it's saying that every minute, the ant can move 30 meters.  So how many meter would it move in 45 minutes?

30 meters = 1 min

x meters = 45 min

1 min x 45 = 45 min

30 meters x 45 = 1,350 meters

So, I believe the answer would be 1,350 meters.

Answer:

11.025m

Explanation:

Using kinematics,

u = Initial velocity = 0.

t = Time taken = 1.5sec.

a = Acceleration from gravity = 9.8m/s^2

Distance = s

= ut + 1/2 * a * t^2

= 0 + 1/2 * 9.8 * (1.5)^2

= 11.025m

The egg fall from the nest of a tree is 11.025 m.

To find height from where the egg fall, the given values are:

Time taken t = 1.5 seconds.

By knowing the concept of Kinematics,

  For a particle moving with a constant acceleration, its displacement after a time period is given by

           s = ut +1/2 at²

where, u - initial velocity,

t - Time,

a - acceleration.

As u is the Initial velocity = 0.

t = 1.5s

Acceleration from gravity = 9.8m/s²

Here, Distance = s

Substituting all the values in the formula,

s = ut + 1/2 ( a × t²)

  = 0 + 1/2 × 9.8 × (1.5)²

Distance s = 11.025m

So, the distance the egg fall from a nest of a tree is s = 11.025 m.

Explanation:

This problem is on the capillary action of water and tube

we are going use the formula below for the rise in liquid level

where h= height of liquid level in the capillary tube

          T= surface tension = 0.073 Nm

          ∅= angle of contact = 60 degrees

          r= radius of bore of capillary tube = 5/2= 2.5 mm to m= 2.5/1000=  

          2.5*10^-3

          g= acceleration due to gravity = 9.81 m/s^2

         ρ= density of the liquid (assume water 1000 kg/m³)

we can now substitute to solve for h

[tex]h=\frac{2*0.073cos60}{ 2.5*10^-^3*9.81*10^3} \\\\h=\frac{2*0.073*0.5}{ 2.5*9.81}\\\\h=\frac{0.073}{ 2.5*9.81}\\\\h=\frac{0.073}{ 24.525}\\\\h=\frac{0.073}{ 24.525}\\\\h= 0.0029\\h= 2.9*10^-^3mm[/tex]

HAVE A GOOD DAY!

Answer:

Period = 0.0167 seconds

Frequency = 60 Hz

Explanation:

Period: This can be defined as the time take by a wave to complete on cycle. The S.I unit is (s)

Frequency: This is the number of cycle completed by a wave. The S.I unit is (Hz)

From the question,

T = t/n................................... Equation 1

Where T = period, t = time take to complete n oscillation, n = number of oscillation.

Given: t = 1 seconds, n = 60.

Substitute these values into equation 1

T = 1/60

T = 0.0167 seconds.

Also,

F = 1/T........................... Equation 2

Where F = frequency

Given: T = 0.0167 seconds,

Substitute these value into equation 2

F = 1/0.0167

F = 60 Hz

Hope this helps

Thermos considered a closed system as matter and energy cannot enter or leave the system when the thermos lid is on tightly. The correct option is C.

Any artifact or part of an object that can be evaluated using physics laws is referred to as a physical system.

Physical systems include atoms and bodies of water. The environment is everything outside the system, and it is overlooked in the assessment except for its impacts on the system.

A physical system is a combination of parts or elements that exhibit behavior that the constituents do not. Physical systems are made up of matter and energy.

In physics, chemistry, or engineering, a closed system is a purely natural system that does not permit the transmission of matter into or out of the system, but does allow the transfer of energy.

Thus, C is the correct answer.

Answer:

The speed of the bag just before it reaches the ground is 21.71 m/s.

Explanation:

The speed of the bag can be found using the following equation:

[tex] v_{f}^{2} = v_{0}^{2} - 2gy [/tex]

Where:

[tex]v_{f}[/tex] is the final speed =?

[tex]v_{0}[/tex] is the initial speed = 7.7 m/s

g: is the gravity = 9.81 m/s²

y: is the height = 21 m

[tex]v_{f}^{2} = v_{0}^{2} - 2gy = (7.7 m/s)^{2} - 2*9.81 m/s^{2}*(-21 m) = 471.31 m^{2}/s^{2}[/tex]

[tex]v_{f} = 21.71 m/s[/tex]

Therefore, the speed of the bag just before it reaches the ground is 21.71 m/s.

Answer:

the direction of acceleration of the vehicle is the same direction of its velocity of car

s acceleration has the opposite direction to the car speed.

Explanation:

The initial acceleration of the car can be calculated with

          v = v₀ + a t

          a = (v-v₀) t

indicate that the initial velocity is zero (v₀ = 0 m / s)

         a = v / t

         a = 300 / t

the direction of acceleration of the vehicle is the same direction of its acceleration movement.

When the car collides with the wall, it exerts a force in the opposite direction that stops the vehicle, therefore this acceleration has the opposite direction to the car speed. But your module must be much larger since the distance traveled to stop is small

Answer:

  a = -7.29 m / s²

Explanation:

For this exercise we must use Newton's second law,

          F -W = m a

Force is electrical force

         F = k q₁ q₂ / r²

         k q₁ q₂ / r² -mg = m a

indicate that the charge of the two spheres is equal

         q₁ = q₂ = q

         a = (k q² / r² - m g) / m

         a = k q² / m r² - g

Let's reduce the magnitudes to the SI system

        m = 0.19 g (1kg / 1000 g) = 1.9 10⁻⁴ kg

        q1 = q2 = q = -23.0 nC (1C / 10⁹ nC) = -23.0 10⁻⁹ C

        r = 10.0 cm (1m / 100cm) = 0.1000 m

let's calculate

        a = 9 10⁹ (23.0 10⁻⁹)² / (0.1000² 1.9 10⁻⁴) - 9.8

        a = -7.29 m / s²

The negative sign indicates that the direction of this acceleration is downward
