The charge in fig A is positive, in fig B is positive and in fig C is negative. this is given by the Fleming's left hand rule.

In magnetism and electromagnetic, the Fleming Left-Hand Rule and Fleming Right-Hand Rule are fundamental principles. They were created by John Ambrose Fleming in the late 19th century as an easy method of determining the direction of motion in an electric motor or the direction of electric current or electric positive charge in an electric generator. It is crucial to remember that these criteria only indicate the direction of the three parameters (magnetic field, current, and force) when the direction of the other two parameters is known and do not define their magnitude.

Answer: 11%

Explanation:

Given that

X = ab^2/C. Calculate percentage error in X, when percentage error in a,b,c are 4,2 and 3 respectively.

Percentage error of b = 2%

Percentage error of b^2 = 2 × 2 = 4

When you are calculating for percentage error that involves multiplication and division, you will always add up the percentage error values.

Percentage error of X will be;

Percentage error of a + percentage error of b^2 + percentage error of c

Substitute for all these values

4 + 4 + 3 = 11%

Therefore, percentage error of X is 11%

Explanation:

We can create a 30-60-90 triangle. The distance she walked is then the hypotenuse of the triangle, and using 30-60-90 triangle rules, we have the following:

The North leg is opposite to the \(30^{\circ}\) angle. Therefore, if we call this distance \(y_N\), we have the following:

\(\sin 30^{\circ}=\frac{y_N}{100},\\\frac{1}{2}=\frac{y_N}{100},\\y_N=\fbox{$50\:\mathrm{m}$}\).

The East leg is opposite to the \(60^{\circ}\\\) angle. If we call this distance \(x_E\), we have:

\(\sin 60^{\circ}=\frac{x_E}{100},\\\frac{\sqrt{3}}{2}=\frac{x_E}{100},\\x_E=\fbox{$50\sqrt{3}\:\mathrm{m}$}\).

A planet whose mass is half of the mass of Earth and radius equal to the radius of the Earth, the acceleration due to gravity on the surface of the planet would be  19.6m/s².

Large, circular celestial objects that are neither stars nor their remnants are known as planets. The nebular hypothesis, which states that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disc, is currently the best theory for planet formation. The formula for the acceleration caused by gravity on earth's surface is,

g = GM/R

Now, Mp = M/2

Rp = R/2

The planet's gravitational acceleration is,

gp =  GMp/Rp

gp = (GM/2)/(R²/4) = 2g

gp = 2 × 9.8 = 19.6m/s²

Therefore, the acceleration due to gravity on the surface of the planet will be 19.6m/s².

Answer:

The time the pilots have to take evasive action is approximately 36.699 seconds

Explanation:

The direction of the planes = Towards each other

The speed of each plane, v₁, v₂ = 721 km/h

The initial distance between the two planes, d = 14.7 km

The relative velocity of the two planes, v = v₁ + v₂

v = 721 km/h + 721 km/h = 1,442 km/h

The time it will take the planes to meet, t = d/v

∴ t = 14.7 km/(1,442 km/h) = (21/2,060) h × 60 min/hr × 60 s/min ≈ 36.699 s

The time it will take the planes to meet = The time the pilots have to take evasive action, t ≈ 36.699 seconds.

An example of a way to conserve energy in a home is "Replacing old windows with new ones." The correct option is D.

Conserving energy in a home involves reducing energy consumption and improving energy efficiency. Replacing old windows with new ones is an example of improving energy efficiency.

Old windows can be a significant source of energy loss due to poor insulation and air leaks. By replacing them with new, energy-efficient windows that provide better insulation and minimize air leakage, energy consumption can be reduced, making it an effective way to conserve energy in a home.

A. Removing weather-stripping around doorways: Weather-stripping around doorways helps prevent air leaks, which improves energy efficiency by reducing heating or cooling loss. Removing weather-stripping would result in increased energy consumption, making it an incorrect choice.

B. Using old light bulbs: Old light bulbs, such as incandescent bulbs, are less energy-efficient compared to newer, energy-saving options like LED bulbs. Using old light bulbs would result in higher energy consumption, making it an incorrect choice.

C. Reducing the use of insulation: Insulation is an essential component for energy efficiency in homes. It helps to reduce heat transfer and maintain a stable indoor temperature. Reducing the use of insulation would result in increased energy loss and higher energy consumption, making it an incorrect choice.

The skater moves at a 10 m/s speed. The right answer is A.

We must examine the forces operating on the skater in order to calculate their speed. The horizontal force applied to the ground creates the centripetal force, which is pointed in the direction of the circular path's center.

The centripetal force is calculated using the formula F = (mv2) / r, where m is the skater's mass, v is the speed, and r is the circle's radius.

We may convert the skater's horizontal force of 1125 N to the centripetal force as follows:

1125 N = (45 kg * v^2) / 4 m.

We rearrange the equation to find v:

1125 N * 4 m = 45 kg * v^2.

4500 N*m = 45 kg * v^2.

If you multiply both sides of the equation by 45 kg, you get:

100 N*m = v^2.

Taking the square root of both sides gives:

v = 10 m/s.

Therefore, the skater's speed is 10 m/s. The correct option is A.

From highest to lowest condensation temperature, the four general types of materials that made up the solar nebula are refractory metals and silicates, volatile metals and ices, water, and hydrogen and helium.

Refractory metals and silicates, such as iron, nickel, and silicon, have the highest condensation temperature and would solidify first in the cooling solar nebula. Volatile metals and ices, like zinc and carbon dioxide, have a lower condensation temperature and would condense next. Water has a lower condensation temperature and would come after volatile metals and ices, while hydrogen and helium have the lowest condensation temperature and would not condense until very low temperatures were reached. These materials formed the building blocks for the planets in the solar system.

The acceleration of the block is 6.4 m/s².

To calculate the acceleration of the block, we need to consider the forces acting on it.

The applied force is 40 N, and since it is the only horizontal force in the direction of motion, it is the net force acting on the block.

The frictional force opposing the motion is 8 N.

The acceleration, we can use Newton's second law, which states that the net force acting on an object is equal to its mass multiplied by its acceleration (F = ma).

The net force is the difference between the applied force and the frictional force:

40 N - 8 N = 32 N.

Now, we can plug the values into Newton's second law:

32 N = 5 kg × a.

Solving for the acceleration (a), we get

a = 32 N / 5 kg

a = 6.4 m/s².

Therefore, the acceleration of the block is 6.4 m/s².

A left-linear grammar is a kind of grammar in which all the production rules are of type A → aB or A → a, where A and B are non-terminals and a is a terminal symbol.

An NFA (Nondeterministic Finite Automaton) can be transformed into a left-linear grammar using the following steps:

If q0 is the initial state of NFA, S → q0B is the starting rule, where B is the first state reached from q0 using an ε-transition.

If qf is the final state of NFA, then we create a rule of form B → a, where a is the input symbol, and also a rule of form B → aC, where a is the input symbol and C is the state reached from qf after consuming a.

The rest of the rules are generated based on the following principle:

If (p,a,q) is a transition of NFA, then we create a rule of form C → bD, where b is an input symbol, and D is the state reached from q after consuming a.

Consequently, we obtain a left-linear grammar from an NFA directly.

We can directly get left-linear grammar from an NFA by utilizing the above-described method. This is helpful because NFA is more versatile than a grammar, as it can recognize regular languages without needing to explicitly list all of their strings.

In contrast, grammar recognizes the language by explicitly listing all of its strings. A language may have an infinite number of strings, which makes grammar impractical to use in such cases.

Automata, on the other hand, are more practical in this situation because they define languages more naturally, by defining a set of strings that can be accepted by an automaton.

A left-linear grammar can be directly obtained from an NFA using the method described above. This technique is useful because automata are more versatile than grammars, making them more practical for languages with an infinite number of strings.

When a charged body is placed near the conductor, the opposite charge is appeared on the one side of the uncharged conductor body near the charged body under the effect of induction.

The opposite charge on the another body is also known as the induced charge.

The perpex rod in the given question is charged.

let the charge on the perpex is positive as shown in the figure.

Then, the polystrene sphers (insulator uncharged sphere) will not have any charge induced as the charges are not free to move inside the insulator.

Thus, when a charged perspex rod is placed close to a suspended polystyrene sphere then the induced charge on the sphere is not observed under the phenomenon of induction process and sphere remain uncharged.
