Answers

Answer 1

Answer:

Matter in the universe is made up of atoms, particles if electrons were to be stationary, they would have fallen into the nucleus because of electrostatic force acting on them destroying very existence of an atom we know.

A boat at anchor is rocked by waves whose crests are 28 m apart and whose speed is 7 m/s. How often do these waves reach the boat? State your answer in terms of frequency (Hz) and period T (seconds).

Answers

Answer:

0.25 Hz

4 s

Explanation:

Speed = wavelength × frequency

7 m/s = 28 m × f

f = 0.25 Hz

Frequency = 1 / period

A charged particle of 5.1 nC and another with 2.6 nC are separated by a distance of 5.5 m. What is the electric potential energy between the particles?

Answers

Answer:

The electric potential energy between the particles is 2.167 x 10⁻J

Explanation:

Given;

a charged particle, q₁ = 5.1 nC

another charged particle, q₂ = 2.6 nC

distance between the charged particle, r = 5.5 m

The electric potential energy between the charged particles is calculated as;

[tex]U_E = \frac{kq_1q_2}{r}[/tex]

where;

[tex]U_E[/tex] is the electric potential energy between the particles

k is coulomb's constant = 8.99 x 10⁹ Nm²/c²

Substitute the given values and solve for electric potential energy;

[tex]U_E = \frac{kq_1q_2}{r} = \frac{8.99*10^{9}*5.1*10^{-9}*2.6*10^{-9}}{5.5} \\\\U_E = 2.167 *10^{-8} \ J[/tex]

Therefore, the electric potential energy between the particles is 2.167 x 10⁻J

Ski lift carry people along 150 m cable up the side of a mountain. Riders are lifted a total of 75 m in elevation. What is the ideal mechanical advantage of the ski lift?

Answers

Ideal Mechanical Advantage (IMA) can be found by using the formula:

IMA = ID/OD

ID = Input Distance

OD = Output Distance

In the question, we are given:

ID = 150

OD = 75

Now, solve the expression with what we have.

IMA = 150/75

IMA = 2

Therefore, the IMA is 2.

Oliver builds a circuit connecting a light bulb to a battery with wires, leaving a gap in one of the wires. He places several objects across the gap to close the loop. He wants to see which objects allow electricity to flow and turn on the light bulb. Why do some materials allow electricity to flow through while others do not?



A. Electricity will flow if the atoms in the material are bound tightly to each other.

B. Electricity will flow if the atoms in the material are bound loosely to each other.

C. Electricity will flow if the electrons are bound tightly to their atoms in the material.

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Answers

Answer:

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Explanation:

The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.

Thus, the correction for this question is "D"

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

A force of 1000 Newtons is used to push a box on a flat floor. It accelerated at a rate of 5 m/s2. What is the mass of the wagon?

Answers

Answer:

67.56kg

Explanation:

Fapp+mg = ma

Fapp= applied force

mg = reactional force

g = acceleration due to gravity

Where g = 9.8m/s^2 a= 5 m/s2, Fapp= 1000N.

1000N = ma + mg

1000N = m( a+g )

1000N = m ( 5+9.8)

1000N = m×14.8

m = 1000÷14.8

m = 67.56kg.

Hence the mass of the wagon will be 67.56kg

if the 50 kg objects slows down to a velocity of 1 m/s how much kinetic energy does it have?

Answers

Answer: 25

Explanation:

The kinetic energy of the object moving at the given mass and velocity is 25 J.

The given parameters;

mass of the object, m = 50 kgvelocity of the object, v = 1 m/s

The kinetic energy of the object moving at the given mass and velocity is calculated as follows;

K.E = ¹/₂mv²

K.E = ¹/₂ x 50 x 1²

K.E = 25 J

Thus, the kinetic energy of the object moving at the given mass and velocity is 25 J.

A sphere of radius 10.0cm is moulded into a uniform cylindrical wire of same radius r calculate length in millimeters​

Answers

Answer:

133.33 mm

Explanation:

First we need to find the volume of the sphere. The volume of a sphere is given by:

V = (4/3) * pi * r^3

With a radius of 10 cm, we have:

V = (4/3) * pi * r^3 = 4188.79 cm3

The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:

V = pi * r^2 * h

Where h is the height of the cylinder, and for this case, it will be the length.

The radius is the same old radius, so we have:

4188.79 = pi * 10^2 * h

h = 4188.79 / 100pi = 13.3333 cm

In millimeters, we have h = 133.33 mm

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe

Answers

Answer:

20 gram of H as the greastest volume

Explanation:

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe

Given that,

40.0 g of Ar

20.0 g of Ne

20.0 g of h

24.0 g of he

The ideal gas equation ; Pv = nRT

where P is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of mole

which is equal to

n = m / M

where m is the given mass

M is the molar mass

The given gas sample are at the same temperature and pressure,

So, the temperature, pressure and gas constant are fixed.

Therefore the volume is proportional to the given mass and molar mass

V ∝ m/M

Substitute the given mass and molar mass of given masses for comparison

No of mole of Ar = mass / molar mass

= 40 / 40 = 1 mole

No of mole of Ne = mass / molar mass

= 20 / 20 = 1 mole

No of mole of h = mass / molar mass

= 20 / 1 = 20 mole

No of mole of he = mass / molar mass

= 24 / 4 = 6 mole

Hence, 20 gram of H as the greastest volume

Um joalheiro recebe uma encomenda onde ele deve fazer alguns anéis de prata. Ele dispõe de um pedaço de 100 g de prata mas precisa derrete-lo para colocar a prata em moldes específicos e construir esses anéis. O principal problema desse procedimento é que a temperatura de fusão da prata é muito alta e requer condições especiais. A prata possui temperatura de fusão de 961 ºC, calor latente de fusão de 21 cal/g e calor específico no estado sólido igual a 0,056 cal/gºC. Determine a quantidade de calor aproximada para fundir as 100 g de prata sabendo que sua temperatura inicial é de 20°C. A 2,1 kcal B 0,5 kcal C 7,4 kcal D 5,3 kcal E 6,3 kcal

Answers

Answer:

Correct option: C -> 7.4 kcal

Explanation:

First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:

941 * 0.056 * 100 = 5269.6 cal

Then, for the melting process, we will need:

21 * 100 = 2100 cal

So the total energy needed is:

5269.6 + 2100 = 7369.6 cal = 7.4 kcal

Correct option: C

Answer:

Explanation:

( Using the mirror formula)

1/ u + 1/v = 1/f

( introducing magnification; m into the formula )

u( 1/u  + 1/v ) =u×1/f

1 + u/v =u/f

( But u/v =1 ÷v/u= 1/m)

1 +1/m =u/f

(Supposing m is actually equal to 2, and f =30 cm, then;)

1 + 1/2 =u/30

3=u/15

3×15=u

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?

Answers

Answer:

white

Explanation:

This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.

Now, in diffraction fo a single slit we always have a central maximum (for all the colors)

This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white
