1) The relationship in between the electrical energy carriesd by the transmission wires and the amount of the heat loss in it is due to the reason that when the electricity is flown through the wires there are some resistance found in these wires which creates a disturbance in the efficient flow of electricty.Also we know that current have an heating effect when it is in motion as due to if a large amount or magnitude of electricity is flown through the transmission wires it will carry a larger heat effected and also due to the resistance is provided by the wires and so the process of heat loss takes place.

2)It is important to minimize current in transmission wires due to minimize the heat loss and resistance on flowing electric current to make the system more efficient

3)Given Resistance = 250 ohms

Electric potential = 150 volts

so we know Power =

volt^2/Resistance =

=(150^2/250)(ohms/volts)

=(22500/250)watt = 90 watt

4)Heat energy (H) = Power(P)×Time(t)

4)Heat energy (H) = Power(P)×Time(t)= (90×2)joules = 180 joules

Hope it helps

Answer:

the speed of the wave is 0.65 m/s

Explanation:

Given;

distance between two successive crests, λ = 1.4 m

number of crests, n = 8

number of waves formed = 7

The total distance covered by the wave, d= 7λ = 7 x 1.4 = 9.8 m

time of motion of the wave, t = 15 s

The speed of the wave is calculated as;

V = d/t

V = 9.8 / 15

V = 0.65 m/s

Therefore, the speed of the wave is 0.65 m/s

Answer:

Gaseous; liquid.

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Some examples of the planet are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.

Basically, the planets are divided into two (2) main categories and these includes;

I. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

II. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.

In conclusion, Planets in the solar system can vary from rocky and terrestrial objects to gaseous and liquid object.

However, the set of characteristics which is unique to the outer planets are gaseous and liquid.

Answer:

24000N

Explanation:

The mass of the object stays the same, regardless of its gravitational field strength. But, weight=mass*gravitational field strength.

So, the gravitational field strength on Earth is 10N. 2400*10=24000.

Explanation:

I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.

First row, KE = 0

Second row, KE = 220500 J

Third row, KE = 183750 J

Fourth row, KE = 205800 J

That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.

Answer:

P = V * Q      potential energy = potential * charge

V = =3.09 J / 6.93 * 10E-4 C = 4460 Joules / Coulomb

The electric potential, V at the point given the data from the question is –4458.87 V

The electric potential or electromotive force (EMF) is defined as the energy supplied by a battery per unit charge. Mathematically, it can be expressed as:

Electromotive force (EMF) = Work (W) / charge (Q)

V = EMF = W / Q

V = W / Q

V = –3.09 / 6.93×10⁻⁴

V = –4458.87 V

Answer:

The lens to be used for the objective is lens A

Explanation:

The objective of a compound microscope

The focal length of the lens used for the objective = 1/(magnification obtained)

The focal length of most modern is equal to the tube length

The range of sizes for the focal length of a microscope is between 2 mm and 40 mm

Therefore, the appropriate lens to be used for the objective of the compound is lens A that has a focal length of 0.50 cm = 5 mm

Answer: Mineral and non- mineral components circulate in the environment in different forms whether it is in the form of solid, liquid, or gas.

Explanation:

Plants take up the minerals like calcium, potassium, nitrogen, sulphur, and others from the soil and utilize them for their survival and growth. These minerals are stored in the flowers, leaves, roots, and other plant parts and these plant parts are consumed by humans and animals. So, inorganic minerals from the soil are converted into organic forms by the plants again the minerals are decomposed into inorganic forms after the death of organisms and again mineral is converted into inorganic form in the soil and these minerals can become the component of the rocks after the sedimentation of the soil.

Answer:

30 N

Explanation:

The normal force is the component of a contact force that is perpendicular to the surface that an object contacts. This normal force prevents the surfaces from penetrating each other.

Let us assume that the acceleration due to gravity (g) is 10 m/s². Hence the weight of the book (W) is:

W = mass of book * acceleration due to gravity = 3 kg * 10 m/s² = 30 N

The normal force ([tex]F_n[/tex]) is gotten using:

Summation of vertical force = m[tex]a_y[/tex]

[tex]F_y=ma_y\\\\F_n-mg=0\\\\f_n=mg=3kg(10m/s^2)=30\ N[/tex]

"42 m/s" is the appropriate answer.

Explanation:

Given:

Initial speed of Ball 1,

= 14 m/s

Now,

If the initial speed of ball 1 is doubled, then the speed of ball 2 will be:

⇒ [tex](V_{fx})_2=\frac{2m_1}{m_1+m_2}(v_1x_1)[/tex]

hence,

Doubling ([tex]v_1x_1[/tex]) will double [tex](V_{fx})_2[/tex],

⇒ [tex](V_{fx})_2=2\times 21[/tex]

The distance of the object from the mirror Is = –8 cm

The image distance from the mirror = –1.60cm

The magnification of the image = 0.20

The distance of the object from the mirror can be calculated using the formula below:

magnification= – image distance/ object distance

Substitute the available values into the equation above,

0.20 = – 1.60/ X

Make X the subject of formula,

X = – 1.60/0.20

X = – 8cm

The negative sign indicates that the image is virtual which is formed behind the mirror.

Therefore, the distance of the object from the mirror Is = –8 cm.

Explanation:

Answer:

Because Jupiter is a much larger planet than Earth, its gravitational pull is 240% stronger than that of earth. This is why sawdust, which is lighter than its equivalent measure of sugar would weigh more on Jupiter.

Explanation:

Let's assume that a type of bag can contain 50 kilograms of sugar. If that same bag was filled up with sawdust instead, it would weigh far less than 50Kg.

If that bag of sawdust, on earth weighed 35Kg for instance, on Jupiter, the new weight would be:

35Kg x 2.4 = 84Kg

Put differently, Jupiter simply has a stronger gravitational pull than earth. This extra pull is attributed to its size.
