Explanation:

Answer:

45.11 kmph and 12.530 m/s

Explanation:

Average speed = Total distance travelled / Total time taken

406/9 gives the answer in kilometers

And we convert it to m/s by multiplying it with 1000/3600

Answer:

it can be calculated by measuring the final distance away from a point, and then subtracting the initial distance

c- temperature

The speed of sound increases with increasing temperature .

We are given:

Mass of load = 140 kg

Acceleration = 0.4 m/s² downward (from Q24)

24. Finding the tension in the cable:

Ma = Mg - T

where 'a' is the acceleration of the load and T is the tension in the cable

replacing the variables, we get:

(140)(0.4)  = (140)(9.8) - T

T = (140)(9.8) - (140)(0.4)

T = 1372 - 56

T = 1316N

25. Finding the distance covered when the load accelerates for 20 s:

in this case, the load will start from rest

so, initial velocity = 0 m/s

acceleration = 0.4 m/s²

from the second equation of motion:

s = ut + (1/2)at²

where s is the distance covered, u is the initial velocity and t is the time taken

s = (0)(20) + (1/2)(0.4)(20)²

s = 0 + 0.2*(400)

s = 80 m

here we didn't take the acceleration due to gravity of the mass into consideration because it is connected to the crane, which would act against any forces and since we are given that the total acceleration is 0.4 m/s², we will just assume that it's the final acceleration of the mass

Answer:

[tex]k.e = \frac{1}{2} m {v}^{2} \\ {v}^{2} = {u}^{2} + 2gs \\ {v}^{2} = 0 + (2 \times 9.8 \times 15) \\ v = 17.1 \: m {s}^{ - 1} \\ k.e = \frac{1}{2} \times m \times {17.1}^{2} \\ = 147m \: joules \\ m \: is \: mass[/tex]

Kinetic energy of the rock just before hitting the water is 147m joules where m is the mass of the object.

The kinetic energy of an object is defined as the energy it possesses due to its motion. It is the work required to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains the kinetic energy as long as its momentum does not change.

It is directly proportional to the mass of the object and the square of its velocity:[tex]K.E. = 1/2 mv^2[/tex].

Where, m= mass of the object

v= velocity

So if the units of mass are in kilograms and the units of velocity are meters per second, then kinetic energy has units of kilogram-meter squared per second squared.

For above given information,

[tex]K.E= 1/2 mv^2\\v^2= u^2 + 2gs\\ \\v^2= 0+ (2* 9.8*15)\\v^2= 294 m/s\\So, K.E. = 1/2 m* 294 m/s\\K.E.= 147m joules[/tex]

Thus, Kinetic energy of the rock just before hitting the water is 147m joules where m is the mass of the object.

Answer:

A Couple in a bicycle is usually generated by the gravitational force and the corresponding reaction forces of the floor. A couple is a force which encourages or prevents a body turning in motion.

The wheels help in the movement and motion of the bicycle from point A to B. The chain which connects different parts help in the rotation of the bicycle wheels through the movement of the pedals by the legs

Answer:

2.4 secs.

Explanation:

Current (A) = Charge (coulomb)/Time(sec)

We are looking for time. So:

Time (sec) = Charge (coulomb)/Current (A)

↓

12coulombs/5.0A = 2.4 secs

The turning moment the balloon produces about the pivot on the ruler is 0.0096 N-m.

The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque. As a result, torque can be thought of as the rotational counterpart to force. The axis of rotation is a straight line about which an item rotates.

Weight of the balloon and carbon di oxide: w = 0.06 N.

Distance from pivot: d = 16 cm = 0.16 m.

The length of the ruler pivoted at the center = 100 cm = 1 m.

Hence,  the turning moment the balloon produces about the pivot on the ruler = wd = 0.06 × 0.16 N-m = 0.0096 N-m.

So, the turning moment the balloon  is 0.0096 N-m.

Answer: Artificial Selection

Explanation: Artificial Selection is described as the identification of desirable traits in both plants and animals, then enhance them, so that those traits can be manifested in future generations.

This is the scope behind cross breeding of plants and animals and this have largely been used in agricultural sector to improve input (such as disease-resistant seeds) and other biotechnological settings.

Darwin's described artificial selection as the human form of natural selection.

The voltage from one side of the battery all the way around to the other side of the battery is 12v .

If 4 of those volts show up across the circle-thing, then the rest of the 12v ... 8v ... Must show up across the set of parallel rectangles.

To get that answer, I subtracted the 4 from the 12.

do cross multiplication

(x + 2) * 3x = (x + 1) * 5x

6x - 5x = 5x^2 - 3x^2

x = 2x^2

x/x^2 = 2

Answer:

7)  λ = 0.5 m,  8)  f = 4.8 10¹⁴ Hz

Explanation:

The speed of an electromagnetic wave is

          c = λ f

where c is the speed of light in vacuum c = 3 10⁸ m / s

7) indicate the frequency f = 6.0 10⁸ Hz

we do not know the wavelength

         λ = c / f

we calculate

        λ = 3 10⁸ / 6.0 10⁸

        λ = 0.5 m

8) indicate the wavelength  λ = 6.25 10-7 m

we do not know the frequency

         f = c / λ

we calculate

        f = 3 10⁸ / 6.25 10⁻⁷

        f = 0.48 10¹⁵ Hz

        f = 4.8 10¹⁴ Hz

Answer:

592000 J

Explanation:

We'll begin by converting 3.7×10⁵ Pa to Kg/ms². This can be obtained as follow:

1 Pa = 1 Kg/ms²

Therefore,

3.7×10⁵ Pa = 3.7×10⁵ Kg/ms²

Next, we shall determine the workdone.

Workdone is given by the following equation:

Workdone (Wd) = pressure (P) × change in volume (ΔV)

Wd = PΔV

With the above formula, the work done can be obtained as follow:

Pressure (P) = 3.7×10⁵ Kg/ms²

Change in volume (ΔV) = 1.6 m³

Workdone (Wd) =?

Wd = PΔV

Wd = 3.7×10⁵ × 1.6

Wd = 592000 Kgm²/s²

Finally, we shall convert 592000 Kgm²/s² to Joule (J). This can be obtained as follow:

1 Kgm²/s² = 1 J

Therefore,

592000 Kgm²/s² = 592000 J

Therefore, the Workdone is 592000 J.

Answer:

Protista

Explanation:

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. Thus, the biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.

Basically, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

Furthermore, the eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

An organism that has only one cell, big and has a nucleus is most likely a member of Protista. Thus, a Protista such as euglena, paramecium, amoeba, etc., have a nucleus and are unicellular.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
