Nick carries out an experiment in which he swings a rubber bung around his head on a string. Name the force that causes the centripetal force in this experiment

The given statement is false. Because the induced emf is dependent on the number of coil.  

According to  Faraday's law of electromagnetic induction the rate of change of magnetic flux link with coil is responsible for generating emf in the coil result in the flow of amount of current .

So in order to increase the current we need to increase the EMF;

so we can increase it by;

1) Increasing the number of turns

2) Increase the area of the loop

3) By moving the magnet faster

Hence, the given statement is false.

The energy released per kilogram of fuel used is mathematically given as  

energy release per kg= 6.702*10^{-13}. This is further explained below.

Generally, is simply defined as

Energy used per person per year in US = 3-5 X 10^11

Population (No. of person)= 3.1x 10^8

Mass of feut required = 3.5x10^11 x3-1x10 8 x 10 )/6.703 X10^{13} kg

Mass of feut required = 1.62x10^{33}kg

Solution: Mev in Joule 6 = 10 1.60* I0^{-19} J

1 Mev= 1.602 X 10 T

energy release per kg= 1.602*10^{13}/2.39x10^{-3}

Fluorine different from chlorine, bromine, and iodine,because it is the most electronegative and reactive element in the periodic table.

The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.

They are organized in a tabular format, with a row representing an era and a column representing a group.

Elements are ordered in increasing atomic number order from left to right and top to bottom.

Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.

Elements in the same period, on the other hand, will have an increasing order of valence electrons. Fluorine,chlorine, bromine, and iodine are halogens.

Hence,fluorine different from chlorine, bromine, and iodine because it is the most electronegative and reactive element in the periodic table.

Explanation:

Density can be found using the equation: density = mass / volume.

In this case, mass is given in grams (g) and volume is given in milliliters (mL).

You can find the density of the diamonds by plugging the given values into the formula and simplifying.

Density = mass (g) / volume (mL)

Density = 6.21 g / 1.77 mL

Density = 3.51 g/mL

Answer:

0.5 kg

Explanation:

» Concepts

Newton's second law, the Law of Acceleration, states that F = ma, where F = Force in Newtons, m = mass in kg, and a = acceleration in m/s^2.

» Application

We are asked to find the mass of the ball using the equation F = ma. We're also given the force and acceleration, so the equation looks like 5 = 10(m).

» Solution

Step 1: Divide both sides by 10.

Thus, the mass of the ball is 0.5 kg.

The value of the peak power will be 50 W. The peak power is found as two times of the average power. Option C is correct.

Average power is a ratio of total work done by the body to the total time. Its unit is the watt. It is also defined as the rate of total work done by the body.

The given data in the problem is;

Average power = 25 W

Peak power = ?

The peak power is found as;

Peak power = 2 × average power

Peak power=2×25

Peak power = 50 W

Hence, the value of the peak power will be 50 W.

The gravitational attraction between two planets is  4905.95 N

When two objects with masses are placed at a distance, there will an attractive force acting between them.

According to the Newton's law of gravitation, gravitational force is

F = Gm₁m₂ /r²

where r is the distance between the masses m₁ and m₂ and  G is the gravitational constant G = 6.67 x 10⁻¹¹ N-m²/kg²

Substitute the values into the expression, we get

F =  6.67 x 10⁻¹¹ x  2.25 x 10²⁰ x 6.20 x 10¹⁸ / (435,500 x 1000)²

F= 4905.95 N
