Law 2:

Pushing a baby on a swing is easier than pushing an adult on the same swing. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

Law 2:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

Law 1:

A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.

Law 3:

A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.

Law 1:

A book rests on top of a shelf and does not move until a student accidentally knocks it off.

Explanation:

Newton's laws of motion:

Law 1: Law of inertia

Law 2: Law of force (F = mass x acceleration)

Law 3: Law of Action & Reaction

The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

Inertia is defined as the tendency of an object to continue its state of rest or motion.

Here,

Considering the situations given,

1. Pushing a baby on a swing is easier than pushing an adult on the same swing.

This is because, the mass of the baby is lesser than that of the adult. So, according to Newton's force equation,

Force, F = ma

Therefore to push a body with more mass, more force should be applied.

Another situation that follows this law from the given situations is:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

2. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

This is due to the inertia of the water in the glass. This can be explained by law of inertia.

Another situation that follows this law from the given situations is:

A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.

A book rests on top of a shelf and does not move until a student accidentally knocks it off.

3. A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.

This is according to Newton's third law of motion. The law of action and reaction.

Hence,

The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

A planetesimal is an object formed from dust, rock, and other materials. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

Answer:

Magnetic energy is used by an electromagnet  to pick up metallic objects

Explanation:

An electromagnet generates its own magnetic field in presence of electric current.

As an electric current is induced in an electromagnet , it  magnetic dipole arrange themselves in order to behave as a magnet and hence generate magnetic field with a proper north and south. This leads to attraction of metallic object.

Hence, it can be said that Magnetic energy is used by an electromagnet  to pick up metallic objects

Answer:

985 kg/m3

Explanation:

The average density of the human body is 985 kg/m3 k g / m 3 , and the typical density of seawater is about 1020 kg/m3 k g / m 3 .

Explanation:

the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi.). If only the Earth's land area of 150,000,000 km2 (58,000,000 sq. mi.) is taken into account, then human population density is 50 per km2 (129 per sq.

[tex]x=37.975 \textdegree[/tex]

Explanation:

From the question we are told that

1st distance [tex]d_1=752 m[/tex]

2nd distance [tex]d_2=587 m[/tex]

Generally the total distance [tex]d_t[/tex]covered by the man is mathematically given as

[tex]d_t =1st\ distance +2nd\ distance[/tex]

[tex]d_t=752+587\\d_t=1339m[/tex]

Generally the resultant distance traveled is mathematically given as

[tex]d_r^2=d_1^2+d_2^2[/tex]

[tex]d_r=\sqrt{752^2+587^2}[/tex]

[tex]d_r=953.98[/tex]

Generally the angle  using sine rule traveled is mathematically given as

let angle =x

[tex]\frac{sin90}{d_r} =\frac{sinx}{587}[/tex]

[tex]sinx=\frac{sin90*587}{953.98}[/tex]

The focal length of the lens is approximately 115.3 cm. The explaination is  explained below.

To find the focal length of the lens, we can use the lens formula:

1/f = 1/v - 1/u

Where:

f is the focal length of the lens

v is the distance of the image from the lens

u is the distance of the object from the lens

Given:

v = 38.5 cm

u = 57.8 cm

Let's substitute these values into the formula:

1/f = 1/38.5 - 1/57.8

Now, let's calculate the right side of the equation:

1/f = (57.8 - 38.5) / (38.5 * 57.8)

= 19.3 / (2223.3)

≈ 0.008677

Now, we can find the focal length (f) by taking the reciprocal of both sides:

f = 1 / (0.008677)

≈ 115.3 cm

Therefore, the focal length of the lens is approximately 115.3 cm.

Answer:

Energy = 51840 J = 51.84 KJ

Explanation:

The electrical energy delivered to the toy can be found out by the following formula:

[tex]Energy = (Power)(time)\\Energy = (VI)(t)\\Enegry = VIt\\[/tex]

where,

V = Voltage = 3 V

R = Resistance = 2.5 Ω

I = Current = V/R (Ohm's Law) = 3 V/2.5 Ω = 1.2 A

t = time = (4 h)(3600 s/1 h) =  14400 s

Therefore,

[tex]Energy = (3\ V)(1.2\ A)(14400\ s)\\[/tex]

Energy = 51840 J = 51.84 KJ

It's a unit for quadruple centimeters. All of the others are used to charge the amount of water in a specific bowl etc.

Answer:

Suppose that the wave equation is:

f(x) = A*cos(k*x)

The wave is in phase for two points x₁ and x₂ if:

f(x₁) = f(x₂)

And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:

wavelength = x₂ - x₁

In this case, we know that the wave is in phase for two points that are 2 m apart.

Then we can use the points:

x₁ and x₂ such that:

x₂ = x₁ + 2m

We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.

Then the wavelength will be:

wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m

Then the wavelength is 2m.

The correct option is C.

Explanation:

Answer:

1)    v = 2.5 m / s, 2)  v = -0.5 m / s

Explanation:

For this exercise we will use the kinematics relations

1) velocity is defined by

         v = [tex]\frac{dx}{dt}[/tex]dx / dt

this definition serves for the instantaneous and the average velocity if the displacements are linear in time

         v = 20/8

         v = 2.5 m / s

b) for this part we use

          v = [tex]\frac{\Delta x}{\Delta t}[/tex]

         Δx = x_f -x₀

we must place a reference system, where the direction to the right is positive

         x_f = -2 m

         x₀ = +3 m

         Δx = -2 -3

         Δx = -5 m

we calculate

         v = -5 / 10

         v = -0.5 m / s

this value is a scalar
