The initial momentum of the 150 g baseball thrown with a speed of 30 m/s is 4.5 Kgm/s

Data obtained from the question Mass (m) = 150 g = 150 / 1000 = 0.15 KgInitial velocity (u) = 30 m/sFinal velocity (v) = 40 m/sInitial momentum =?

How to determine the initial momentum

Momentum is defined as the product of mass and velocity i.e

Momentum = mass × velocity

With the above formula, we can obtain the initial momentum of the system as follow:

Mass (m) = 0.15 KgInitial velocity (u) = 30 m/sInitial momentum =?

Initial momentum = mu

Initial momentum = 0.15 × 30

Initial momentum = 4.5 Kgm/s

The factors that can cause an induced current in a wire loop are number of turns of the wire, area of the wire and magnetic field strength.

Induced emf

According to Faraday's law of electromagnetic induction, the rate of change of flux in a magnetic field is proportional to the flux through the magnetic field.

emf = dФ/dt

where;

Ф is magnetic flux = BA (magnetic field and area of the coil)

emf = N(BA)/dt

where;

N is number of turns

Thus, the factors that can cause an induced current in a wire loop are number of turns of the wire, area of the wire and magnetic field strength.

A pendulum's time period is the amount of time it takes to complete one oscillation. The pendulum with a length of 3.98 m and a length of 99.4 cm will have a time period of 4 and 1.99 seconds, respectively.

What is the definition of a simple pendulum?

A simple pendulum is a device with a point mass hanging from fixed support and connected to a light inextensible thread.

The vertical line going through the fixed support represents the mean position of a basic pendulum.

h = vertical distance from the point of suspension

L = length of the simple pendulum

The time period of the simple penduum is given by

[tex]\rm T = 2\pi\sqrt{\frac{l}{g} }[/tex]

For l = 3.98 m

[tex]\rm T = 2\times 3.14 \sqrt{\frac{3.98}{9.81} }[/tex]

T = 4 second

For l = 99.4 cm = 0.994 m

[tex]\rm T = 2\times 3.14 \sqrt{\frac{0.994}{9.81} }[/tex]

T = 1.99 second

The time period of the pendulum having 3.98 m and 99.4 cm in length will be 4 and 1.99 seconds respectively.

mass of liquid = mass of flask and liquid - mass of flask = 50-34 = 16g

density = mass/volume
= 16/20 = 0.80 g/cm^3

If the mass of an empty flask is 34 g. The volume of liquid added to the flask is 20 cm3. The total mass of the flask and the liquid is 50 g.then the density of the liquid would be 0.8 gram / cm³

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

By using the above formula for density

ρ = mass / volume

As given in problem f the mass of an empty flask is 34 g. The volume of liquid added to the flask is 20 cm3. The total mass of the flask and the liquid is 50 g.

The mass of liquid = 50 -34

= 16 gram

volume of the liquid = 20 cm³

density of liquid = 16/20

= 0.8 gram / cm³

Thus, the density of the liquid would be 0.8 gram / cm³

Fibreglass - Insulatorpiece of paper - Insulatorcopper - ConductorStone - InsulatorAluminium - Conductorplastic spoon - InsulatorIron - ConductorWood - InsulatorRuler - Conductor/InsulatorPlastic straw - InsulatorGlass - InsulatorBrass - ConductorGold - ConductorCotton bud - InsulatorSilver - Conductor

Explanation:

Conductors are substances that can conduct electricity/heat. Usually, metals are good conductors as they have free electrons — electrons that are loosely held by the nucleus and are free to travel across the surface(they stay on the surface and are not free to escape into the surrounding space).

These free electrons help in the conduction of heat/electricity. Hence, substances containing these free particles are conductors.

Insulators do not allow heat/electricity to flow through them. Mostly, they are made up of molecules that are held together by strong intermolecular forces(eg: Plastic ).

[Note#9: Metal rulers are conductors whereas wooden rulers are insulators so, "ruler" comes under the category of both insulator as well as conductor].

People have a right to revolution when a government becomes destructive to their fundamental rights (such as life, liberty, and the pursuit of happiness) and fails to secure those rights. The right to revolution is grounded in the idea that governments derive their just powers from the consent of the governed and exist to protect the rights and well-being of the people.

When a government fails to fulfill this duty, the people have the right to alter or abolish it and establish a new government that better serves their interests and well-being.

The concept of a right to revolution is often associated with the idea that when a government becomes destructive to the fundamental rights of its citizens and fails to secure their well-being, the people have a right to overthrow or alter that government. This concept is articulated in the United States Declaration of Independence, which was adopted on July 4, 1776, and laid out the reasons for the American colonies' decision to separate from British rule.

The relevant passage from the Declaration of Independence states:

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."

To reach the camp from the last position, you must walk 10.95 km due East.

Distance you must walk to reach the camp

The distance you must walk to reach the camp is calculated by applying Pythagoras theorem as follows;

Due north distance, a = 7 km

North east distance, b = 13 km

[tex]b^2 = x^2 + a^2\\\\x^2 = b^2 - a^2\\\\x = \sqrt{b^2 - a^2} \\\\x = \sqrt{13^2 - 7^2} \\\\x = 10.95 \ km[/tex]

Thus, to reach the camp from the last position, you must walk 10.95 km due East.
