Answer:

An object in motion will remain in motion until it experiences an unbalanced force.

Explanation:

This is part of Newton's first law. An unbalanced force is there to offset the object in motion, such as a ball versus a wall. A wall will stop the ball from moving.

Answer:

3.375 m/s²

Explanation:

Using equation of motion:

v = u + at

Here, v = 27m/s & u = 0m/s & t = 8 sec

Let the acceleration be a.

=> 27 = 0 + 8(a)

=> 27/8 = a

=> 3.375 m/s²

Answer:

the pressure exerted at the base of the container is 490 N/m²

Explanation:

Given;

density of water, ρ = 1,000 kg/m³

base of the rectangular container, = 50 cm by 30 cm

height of water in the tank, h = 5 cm = 0.05 m

The pressure exerted at the base of the container is calculated as;

P = ρgh

where;

g is acceleration due to gravity = 9.8 m/s²

P = 1000 x 9.8 x 0.05

P = 490 N/m²

Therefore, the pressure exerted at the base of the container is 490 N/m²

Answer:

Laterite is your correct answer

Explanation:

Well i took the quiz and made a %100 meaning i am correct.

The laterite soil is found in warm, humid climates

A variety of rocks weathered under highly oxidising and leaching circumstances to form laterite soil, which is present in the soil layer and is rich in iron oxide.

Given data ,

Let the soil be represented as A

Now , the soil is found in warm, humid climates

The laterite soil is is rich in iron and aluminium, are assumed to have developed in hot, humid tropical climes. Because to the substantial concentration of iron oxide, nearly all laterites have a rusty-red colour.

They develop as a result of prolonged, intensive erosion of the underlying rock material, which most frequently takes place during periods of high temperatures and heavy precipitation that alternate with periods of dry weather.

Hence , Laterite is the type of soil is found in warm, humid climates.

Answer: C

Explanation: I did the test

We need to use 6 red circles and 8 blue circles to represent the 6 protons and 8 neutrons in the nucleus. Then, we need to place 6 yellow circles around the nucleus to represent the 6 electrons in the atom. Option C is correct.

To create a correct model of a Carbon-14 atom, we need to follow the steps that represent the correct number of protons, neutrons, and electrons in a carbon-14 atom.

Carbon-14 has 6 protons and 8 neutrons, so we need to use a total of 6 red and 8 blue circles in the nucleus. It also has 6 electrons, so we need to place 6 yellow circles around the nucleus.

The correct steps to follow to create a model of a Carbon-14 atom are:

B. steps 1, 4, 6

Step 1:  Use 6 red circles for the nucleus of the atom

Step 4: Add 8 blue circles to the nucleus of the atom

Step 6:  Place 6 yellow circles around the nucleus of the atom

Therefore, we need to use 6 red circles and 8 blue circles to represent the 6 protons and 8 neutrons in the nucleus. Then, we need to place 6 yellow circles around the nucleus to represent the 6 electrons in the atom.

Answer:

A) 35 ft

B) 5 ft

C) Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick

Explanation:

A) Total distance covered by the dog = 20 + 15

                                  = 35 ft

B) Since the other distance covered by the dog before chewing the stick, after the retrieval, was in an opposite direction to the initial direction, then;

total displacement of the dog = 20 - 15

                                  = 5 ft

C) Net displacement = distance covered by the dog to retrieve the stick + distance covered before the dog starts chewing the stick

But, displacement involves a specified direction. The distance covered before the dog starts chewing the stick was in an opposite direction to the initial direction.

Thus,

Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick

Answer:

B

Explanation:

Density=mass/volume

Density=8.5g/17mL

Density=0.5 g/mL

An object has a mass of 8.5 g and a volume of 17 mL, then the density will be 0.5 g/mL. The correct option is b.

The density of matter is a physical quantity that indicates how much mass is contained within a particular volume.

It is defined as a substance's mass per unit volume. In other words, density quantifies how tightly packed a substance's particles are.

We know that:

Density = Mass / Volume

Density = 8.5 g / 17 mL

Simplifying the calculation:

Density = 0.5 g/mL

Therefore, the density of the object is 0.5 g/mL. So, the correct answer is option b. 0.5 g/mL.

Answer:

a)    F = 2000 N , B)   x = 25 m

Explanation:

a) To solve this exercise we can use the relationship between work and kinetic energy

          W = ΔK

The job is

           W = -F x

the negative sign is because the force of the brakes is contrary to the movement

as the car stops its final kinetic energy is zero

           K = ½ m v²

let's substitute

         - F x = 0 - ½ m v²

            F = ½ m v² / x

Let's reduce the magnitudes to the SI system

           v = 72 km / h (1000m / 1km) (1 h / 3600 s) = 20 m / s

let's calculate

          F = ½ 1000 20²/100

          F = 2000 N

b) x = ½ mv2 / F

let's slow down to the SI system

         v = 36 km / h = 10 m / s

let's calculate

             x = ½ 1000 10²/2000

             x = 25 m

If one of the masses is tripled, then their product is tripled, and the force between them is tripled.  The new force is 750N .

Answer:

A: The mass would be 250kg

Explanation:

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.

p= mv

m= p/ v

The explanation to that is:

momentum = mass× velocity

mass= momentum / velocity

Explanation:

Answer:

[tex]40^{\circ}[/tex]

Explanation:

The incident angle is [tex]20^{\circ}[/tex] so the reflected ray will also be [tex]20^{\circ}[/tex].

The normal divides the angle between the incident and reflected ray. So, the angle between them would be

[tex]\text{Incident angle}+\text{Reflected angle}=20+20=40^{\circ}[/tex]

So, the angle between the incident and reflected rays is [tex]40^{\circ}[/tex].

Answer:

η = 1.31

Explanation:

The formula for the refractive index of from air to some other medium is given by the following formula:

[tex]\eta = \frac{c}{v}\\[/tex]

where,

η = refractive index = ?

c = speed of light in air = 3 x 10⁸ m/s

v = speed of light in ice = 2.29 x 10⁸ m/s

Therefore, using these values in the equation we get:

[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.29\ x\ 10^8\ m/s} \\[/tex]

η = 1.31
