What is meant by electric strength?An insulating substance can withstand a certain voltage at its electric strength before losing its ability to insulate. The thickness of the insulating material, as well as the test technique and conditions, will all affect the value for the electric strength.To avoid flash over before breakdown, samples with a thickness of 2mm or more are often examined in oil. Once the breakdown voltage and sample thickness have been determined, the dielectric strength may be estimated. Dielectric strengths for the majority of polymers range from 10 to 30 kV/mm, which is a respectable value.A material's capacity to withstand large voltage swings without experiencing current breakdown is measured by its dielectric strength.To learn more about electric strength refer to:

How long does it take a plane, traveling at a constant speed of 130 m/s, to fly once around a circle whose radius is 2650 m
51.6 seconds long does it take a plane, traveling at a constant speed of 130 m/s, to fly once around a circle whose radius is 2650 m.
The time it takes for an object to travel once around a circle of radius r at a constant speed v can be found using the equation:
T = 2 x π x r ÷ v
where T is the time in seconds, pi is approximately 3.14, r is the radius of the circle in meters, and v is the speed of the object in meters per second.
Given a constant speed of 130 m/s and a radius of 2650 m, the time it would take for a plane to fly once around the circle would be:
T = 2 x π x 2650 m / 130 m/s
T = 51.6 sec
So, it would take approximately 51.6 seconds for a plane traveling at a constant speed of 130 m/s to fly once around a circle whose radius is 2650 m.

Answer:
0.22 A
Explanation:
We must first find the impedence of the circuit using the formula;
√R^2 + (XL)^2
XL = 2πfL
XL = 2 * 3.14 *1000* 30 * 10^-3
XL = 188 Ω
√(200)^2 + (188)^2

An electric cord can be stretched to its elastic limit by a load of 3N. If a 350cm length of the cord is extended by a force of 0.5N, what will be the length of the cord when the stretching force is 2.5N?
Answer:
359cm
Explanation:
The change in length of the cord due to a stretching force of 0.5N is given by Hooke's law:
ΔL = k * ΔF
Where ΔL is the change in length, k is the spring constant and ΔF is the change in force.
Since the spring constant for the cord is 3N/cm, the change in length due to a stretching force of 0.5N is:
ΔL = (3N/cm) * (0.5N) = 1.5 cm
Since the cord is already 350cm long, the total length of the cord when the stretching force is 0.5N is 350cm + 1.5cm = 351.5cm.
To find the length of the cord when the stretching force is 2.5N, we can use the same formula:
ΔL = (3N/cm) * (2.5N) = 7.5 cm
The total length of the cord when the stretching force is 2.5N is therefore 351.5cm + 7.5cm = 359cm.

The electric field inside the wire is equal to 1.5 V/16 cm, or 0.09375 V/cm.
What is battery?
Battery is a device that stores energy and is capable of providing a current of electricity when connected to an electrical device. It typically consists of one or more electrochemical cells, which convert stored chemical energy into electrical energy.
The current density inside the wire is equal to 2.0 A/16 cm, or 0.125 A/cm.
The wire's diameter can be calculated using the formula I = πρd2/4,
where I is the current in the wire,
ρ is the resistivity of nichrome,
and d is the diameter of the wire.
Plugging in the values given,
we get 2.0 = π(1.1×10-6 Ω•m)d2/4, or d2 = 8.18×10-5 m.

Because Earth has a lot of nitrogen in its atmosphere and nitrogen has three atoms, this causes even more bluish coloring since three different paths are possible for any one photon (particle of light). Three paths means that more photons are scattered forward and backward than side-to-side, which will make the sky look bluer still.
A buildup of nitrogen in the atmosphere can result in pollutants like ozone and ammonia, which can reduce visibility, interfere with plant growth, and harm our capacity to breathe.
Does increase in nitrogen cause global warming?"Human nitrogen additions to the soil, in the form of fertilisers, strengthen the greenhouse effect: approximately 60% of nitrous oxide is emitted from fertilised fields, manures, and other agricultural sources," claims Mahesh Pradhan, a nutrient pollution specialist with the UN Environment Programme (UNEP).
AUSTRIA (Thomson Reuters Foundation) - Scientists said on Wednesday that rising nitrogen-based fertiliser use is raising emissions of a greenhouse gas 300 times more potent than carbon dioxide, endangering attempts to keep global warming within globally set limits.
With over 75% of all greenhouse gas emissions and almost 90% of all carbon dioxide emissions coming from fossil fuels like coal, oil, and gas, they are by far the biggest cause of climate change in the world.

A boy exerts a force of 225 N on a lever (Links to an external site.) to raise a 1250 N rock a distance (Links to an external site.) of 0.13 m. If the lever is frictionless, how far did the boy have to move his end of the lever
If the lever is frictionless, to raise the rock a distance of 0.13 m, then the boy has to move the lever to 0.72 m.
An external force that acts upon an object results in a motion of the object, then it is called a work done upon the object by that force.
Given that the external force on a lever is 225 N and on a rock is 1250 N. The distance of motion by the rock is 0.13 m.
Hence the work done by the lever will be equivalent to the work done by the rock to move a particular distance.
Work (Lever) = Work (Rock)
F(lever) x D (lever) = F (rock) x D (rock)
225x D(lever)= 1250 x0.13
D(lever) is 0.72 m
Hence we can conclude that the distance of the motion by the lever is 0.72 m.

Does a ball rolling on an inclined plane have the same acceleration on the way up as it does on the way down?
Answer:
The answer is below
Explanation:
The acceleration of a ball rolling down an inclined plane would be greater than that of the acceleration of a ball rolling up if acted upon by a force of equal magnitude. For a ball rolling down an inclined plane, the acceleration due to gravity (gsinθ) acts in the direction of motion of the ball thereby leading to an increase in the acceleration of the ball; while for a balling rolling upwards, the acceleration due to gravity acts in the direction opposite to the motion of the ball thereby leading to a decrease in the acceleration of the ball.

A car traveling through a tunnel has kinetic energy of 32,987 J and
potential energy of 45 J, what is the total energy of the car?
Answer:
Total energy = 33032 J
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Furthermore, the total mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.
Mathematically, it is given by the formula;
Total mechanical energy = G.P.E + K.E
Given the following data;
Kinetic energy = 32,987 J
Potential energy = 45 J
To find the total energy;
Total energy = P.E + K.E
Total energy = 45 + 32,987
Total energy = 33032 J
