Answer:

see below

Explanation:

first of all, you find the speed of sound in air

which is

speed = frequency x wavelength

so

speed = 200 x 1.5

speed = 300 m/s

speed remains the same in the same medium

so you can use speed and frequency to find wavelength

speed = frequency x wavelength

300 = 600 x wavelength

wavelength = 0.5 m

Answer:

Difference = 1.83 hours

Explanation:

Let the two trips be A and B respectively.

Given the following data;

Distance A = 2000 miles

Speed A = 400 miles

Distance B = 2000 miles

Speed B = 480 miles per hour

To find the time spent;

a. For trip A.

Time A = distance A/speed A

Time A = 2000/400

Time A = 5 hours

b. For trip B.

Time B = distance B/speed B

Time B = 2000/480

Time B = 4.17 hours

Next, we would find the difference between the two trips.

Difference = Time A - Time B

Difference = 5 - 4.17

Difference = 1.83 hours

Therefore, the return trip was much quicker by 1.83 hours.

The return trip of the airplane will be quicker by 1.84 hours

It is given that

Distance covered by the plane D= 2000 miles

The average speed of the plane

 [tex]V_1=400\ \frac{Miles }{hour }[/tex]

The Return Average speed of the plane

[tex]V_2= 480\ \frac{Miles}{hour}[/tex]

Now we will first find the time taken by the airplane during the first visit.

[tex]V_1=\dfrac{Distance }{Time }[/tex]

[tex]Time = \dfrac{Distance }{V_1}[/tex]

Now by putting the values in the formula

[tex]T_1=\dfrac{2000}{400} =5\ hours[/tex]

Now for the return trip time taken by the plane

[tex]T_2=\dfrac{Distance }{V_2}[/tex]

[tex]T_2= \dfrac{2000}{480}[/tex]

[tex]T_2= 4.16\ hours[/tex]

Now the difference between the time will be

[tex]=T_1-T_2=5-4.16=0.86=1.84 \ Hours[/tex]

Thus the return trip of the airplane will be quicker by 1.84 hours

Answer:

a)  F = 2.25 10³ N, b) REPULSIVE.

Explanation:

a) The electric force is given by coulomb's law

           F = [tex]k \frac{q_1q_2}{r^2}[/tex]k q1q2 / r2

in this case nso indicate that the two charges have the same value

           q₁ = q₂ = 2.5 10⁻⁶ C

Let's reduce the magnitudes to the SI system

           r = 0.5 cm (1m / 100cm) = 5 10⁻³ m

let's calculate

           F = [tex]9 \ 10^9 \frac{(2.5 \ 10^{-6})^2 }{(5 \ 10^{-3})^2}[/tex]

           F = 2.25 10³ N

b) In electricity, electric charges of the same sign repel and those of the opposite sign attract

In this exercise, the balls are equal and are rubbed with the same material, for which it acquires charges of the same type, consequently, as the charges are of the same type, they indicate that the negative force is REPULSIVE.

Answer:

C

Explanation:

Warm water and precipitation are transported from the equator to the poles by ocean currents, whereas cold water is returned to the tropics from the poles. Ocean currents control climate globally by balancing out the uneven distribution of solar radiation that reaches Earth's surface.

Short-distance currents can travel across entire ocean basins, while longer ones can even circle the earth. Ocean currents are vital in regulating the climate because they transport heat from the equator to the poles.

The distribution of air temperature is significantly influenced by ocean circulation. The warm Gulf Stream in the North Atlantic and the chilly Peru (Humboldt) Current in South America are two examples of ocean currents with a northward or southbound component that efficiently exchange heat between low and high latitudes.

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

[tex]F=P\times A\\\\F=5\times 25\\F=125\ N[/tex]

So, the weight of the man is 125 N.

Answer:

f=1/t is the equation of frqency

Answer: 2934.75 Joules

Explanation:

Potential energy can be defined as energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

P.E = mgh

Where P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per second square.

h represents the height measured in meters.

Given the following data;

Weight =645

Height = 4.55

P.E = mgh

But we know that weight = mg = 645N

Substituting into the equation, we have;

P.E = 645 • 4.55

P.E = 2934.75J

Potential energy, P.E = 2934.75 Joules.

Answer:

The magnitude of magnetic force between the two parallel wires is 1.13 N.

Explanation:

Given;

length of each wire, l = 31 m

distance between the two parallel wires, r = 0.155 m

current on each wire, I = 168 A

The magnitude of magnetic force between the two parallel wires is calculated as;

[tex]F = \frac{\mu _oI_1I_2 L}{2\pi r} \\\\F = \frac{(4\pi \times 10^{-7}) \times (168)^2 \times (31)}{2\pi \times 0.155} \\\\F = 1.13 \ N[/tex]

Therefore, the magnitude of magnetic force between the two parallel wires is 1.13 N.

Answer:

A-500 N

Explanation:

The computation of the tension in the chain is shown below

As we know that

F = ma

where

F denotes force

m denotes mass = 7

And, a denotes acceleration

Now for the acceleration we have to do the following calculations

The speed (v) of the hammer is

v = Angular speed × radius

where,

Angular seed = 2 × π ÷ Time Period

So, v = 2 × π × r ÷ P

v = 2 × 3.14 × 1.8 ÷ 1

= 11.304 m/s

Now

a = v^2 ÷ r

= 70.98912 m/s^2

Now the tension is  

T = F = m × a

= 7 × 70.98912

= 496.92384 N

= 500 N

Answer: I = 9.0 A

Explanation: Ohm's Law is defined as the relationship between voltage and current: in a circuit, the voltage accross a conductor is directly proportional to the current.

The constant of proportionality is Resistance, whose unit is ohm (Ω).

so, Ohm's Law is

V = R.I

It is asked for the current, so, rearraging:

[tex]I=\frac{V}{R}[/tex]

When added two more batteries, the voltage of the circuit triples:

[tex]V_{final}=3V_{initial}[/tex]

Since they are directly proportional, if voltage triples, so does current:

[tex]I_{final}=3I_{initial}[/tex]

[tex]I_{final}=3(3.0)[/tex]

[tex]I_{final}=[/tex] 9.0

The new current, when driven by 3 batteries is 9.0 A.

Answer:

Option ( B ) is correct .

Explanation:

To lift a heavy weight , inclined plane is used . Use of inclined plane , makes the task easier because instead of force mg , force mg sinθ is to be used which is less than mg . Here θ is inclination of inclined plane.

If h be the height by which weight is to be lifted

potential energy acquired by weight = mgh

work done by force mg sinθ = mgsinθ x d where d is displacement required .

mg sinθ x d = mgh  ( work done by force = potential energy stored in luggage )

d = h / sinθ

d will be more than h

Hence inclined plane increases the distance to be covered by force applied though it decreases the force itself.

Hence option ( B ) is correct .

Answer: A
