Answer:

for velocity we have to use displacement &distance is for speed

Answer:

frequency is equal to the wavelength multiply by the speed of light

Explanation:

wavelength multiply by the speed of light Will give you the frequency

Answer:

O Distance​

Explanation:

With the given information, it is possible to find the distance of the car has traveled on the home from school.

This is possible because distance is the length of path a body covers.

From the given values:

  Distance  = 5208  - 5200  = 8miles

It is not possible to find the displacement because no direction was given.

Also velocity is not possible since the time frame of travel was not state.

Answer:

40g/mol

Explanation:

The molar mass of a compound is the mass in grams of one mole of the substance.

To find the molar mass of NaOH;

a. Atomic mass of Na = 23g

                              O  = 16g

                               H = 1g

b. So, the NaOH will have a molar mass of:

            23g + 16g + 1g   = 40g/mol

The molar mass of NaOH is   40g/mol

Explanation:

Given parameters:

Number of moles of H₂O = 2moles

Unknown:

Mass of  H₂O = ?

Solution:

To solve this problem, use the expression below:

   Mass of  H₂O = number of moles x molar mass

Molar mass of  H₂O = 2(1) + 16  = 18g/mol

  Mass of  H₂O = 2 x 18  = 36g

Answer:

No

Explanation:

It is not possible to have acceleration at constant velocity

0,049 m / s

Wyjaśnienie:

Biorąc pod uwagę, że:

Dystans biegu = 900m

Czas trwania = 205 minut

Długość przejścia = 300 m

Zajęty czas = 205 minut

Średnia prędkość :

(Przebieg + pokonany dystans) / całkowity czas

Średnia prędkość :

(900 m +. 300 m) / 205 + 205

1200 m / 410 minut

Minuty do sekund

1200 / (410 * 60)

1200/24600

= 0,0487804

= 0,049 m / s

Answer: Static Friction

Explanation: As you tilt the book you know that it will stay fixed to start with, but eventually, once the angle is large enough, the book will start to slide. It is the static friction force that holds the book in place at small angles of tilt.

The book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction, so option C is correct.

An item is kept at rest by the force of static friction. The phrase "static friction" can be defined as "the friction people perceive when they attempt to move a stationary object on a surface, but without actually causing any relative motion between the body and the surface it is on."

You can predict that the book will initially remain fixed when you tilt it, but once the angle is sufficiently large, it will finally begin to slide. The book is held in place at slight tilt angles by static friction force.

The formula for the coefficient of static friction is μ = tan θ, here θ is the angle of inclination if the angle is bigger the friction force is more but at 90° when the book is vertical then the friction force will not work on the book

Therefore, the book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction.

Answer:

[tex]s_2=-806m[/tex]

Explanation:

From the question we are told that

Velocity 1 [tex]v=1.34m/s \angle west[/tex]

Distance  [tex]d=6.44km=>6440m[/tex]

Velocity 2  [tex]v_3=2.68m/s[/tex]

Velocity 3  [tex]v_3=0.447m/s \angle east[/tex]

Generally the equation for VT is mathematically given by

[tex]VT=v_1t_1 +V_2t_2[/tex]

[tex]VT=2.68(2400)-0.447t_2[/tex]

[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]

[tex]t_2=1804s[/tex]

Therefore

[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]

[tex]s_2=-806m[/tex]

Mass, m = 20000 kg

Explanation:

The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]

Acceleration of the shark, a = 1.25 m/s²

We need to find the mass of the Shark. The force acting on an object is given by :

F = ma

m is the shark's mass

So,

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]

So, the mass of the Shark is 20000 kg.

Rutherford's model of atoms describes the atom as a tiny, dense particle which contains a positively charged nucleus with electrons which are negative charged moving in orbitals.

Rutherford's model of atoms described the atom as a tiny, dense, positively charged core particle which is called a nucleus, in which nearly all the mass of the atom is concentrated, around within the nucleus which the light, negative constituents, called electrons, circulate at some specific distance, much like the planets which are revolving around the Sun.

During the Rutherford's experiment, the alpha particles are bombarded on the thin piece of gold foil. The alpha particles were expected to pass easily through this gold foil. The discovery of the nucleus of atom was a result of the Rutherford's observation in which a small percentage of the positively charged particles that is protons bombarding on the metal's surface.

Answer:

0.0000076 grams

Explanation:

We're given the half life of Tritium to be 12.3 years. In order to find out the amount of substabce remaining:

Let's first find how many 'half lives' are in 250 years.

[tex]n = \frac{250}{12.3} = 20.325[/tex]

Now what is half life? It means the time taken for a given quantity of an element to lose half it's mass.

So in 12.3 years we can find that The amount of 250 g of Tritium will be 250/2 = 125 g. In 24.6 years we'll have 125/2 = 62.5 g

So now we can devise a formula:

[tex]m = \frac{original \: amount}{ {2}^{n} } [/tex]

Where m is the remaining amount and n is th number of half lives in the time given.

Using this formula we can calculate:

[tex]m = \frac{10}{ {2}^{20.325} } [/tex]

Doing this calculation we get:

[tex]m = 0.0000076 \: g[/tex]

As we can see a very small value remains.
