Answer:

High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Answer:

The speed of the wave as it travelled through the brass bell is;

B. 4,700 m/s

Explanation:

The given parameters are;

The wavelength of the sound wave produced from the brass bell, [tex]\lambda _{(air)}[/tex]  = 3.5 m

The wavelength of the wave in the brass bell, [tex]\lambda _{(brass \ bell)}[/tex]  = 47 m

The frequency of the wave in the brass bell, f = 100 Hz

The given equation for wave speed, v = f × λ

Therefore, the speed of the wave as it travelled through the brass bell, [tex]v _{(brass \ bell)}[/tex], is given as follows;

[tex]v _{(brass \ bell)}[/tex] = f × [tex]\lambda _{(brass \ bell)}[/tex] = 100 Hz × 47 m = 4,700 m/s  

The speed of the wave as it travelled through the brass bell =  [tex]v _{(brass \ bell)}[/tex] = 4,700 m/s

Answer:

Answer:

6.25m

Explanation:

Given parameters:

Masses of the car  = 1000kg

Gravitational force  = 1.067 x 10⁻⁵N

Unknown:

Distance between them  = ?

Solution:

To solve this problem, we use the expression below from the universal gravitational law;

     Fg  = [tex]\frac{G x mass 1 x mass 2}{distance^{2} }[/tex]  

G = 6.67 x 10⁻¹¹

     1.067 x 10⁻⁵  = [tex]\frac{6.67 x 10^{-11} x 1000 x 1000 }{d^{2} }[/tex]  

             d  = 6.25m

Explanation:

The centripetal force is the force that keeps a body moving in a circular path.

The centripetal force is given by; F = mv^2/r

1) We have;

F = 5,600 N

v = 20 m/s

r =?

m = 700 kg

Making r the subject of the formula;

r =mv^2/F

r = 700 × (20)^2/5,600

r = 50 m

2) F = mv^2/r

F = 900 × (5)^2/30

F = 750 N

3) Making r the subject of the formula;

r =mv^2/F

r = 800 × (40)^2/ 16,000

r = 80 m

Answer:

Explanation:

Answer:

0.35

Explanation:

According to Newton's second law;

\sum Fx = ma

Fm - Ff =ma

Fm is the moving force = Wsin theta

Fm = 4(9.8)sin55

Fm = 32.1N

Ff is the frictional force = nmgcos theta

Ff = n(4)(9.8)cos55

Ff = 22.48n

Acceleration a = 6.0m/s²

Substitute the given values into the formula and get the coefficient of friction

32.11-23.48n = 4(6)

32.11-24= 23.48n

8.11 = 23.48

n = 8.11/23.48

n = 0.35

Hence the coefficient of friction is 0.35

Answer:

[tex]75\:\mathrm{seconds}[/tex]

Explanation:

The impulse-momentum theorem states that the impulse of an object is equal to the change in momentum of that object:

[tex]\Delta p=m\Delta v[/tex].

Impulse is also given by [tex]F\Delta t[/tex] where [tex]F[/tex] is the average net force and [tex]\Delta t[/tex] is change in time.

Therefore, we can set both equations equal to each other and solve:

[tex]\Delta p= F\Delta t[/tex].

Assuming that the airplane was initially at rest, its change in momentum is:

[tex]\Delta p =m\Delta v,\\\Delta p=30,000\cdot 50=1,500,000[/tex]

Impulse is represented using [tex]Ns[/tex]. Therefore, convert [tex]20\:\mathrm{kN}[/tex] to Newtons:

[tex]20\:\mathrm{kN}=20,000\:\mathrm{N}[/tex]

Thus:

[tex]1,500,000=20,000\cdot t,\\t=\frac{1,500,000}{20,000}=\fbox{$75\mathrm{s}$}[/tex].

Answer:

Explanation:

The Earth pulls the bicycle downward through the force of gravity, and, in response, the bicycle pulls up on the Earth with a force of equal magnitude. Gravity "pushes" the Earth into the road, which pushes up with an opposite force, canceling gravity. Thus, action reaction forces do not cancel each other.

High pressure systems entail sinking air, while lows entail rising air. High pressure systems form where air converges in the higher levels of the atmosphere. The converging air has nowhere to go and is forced to sink toward the ground. This sinking effect inhibits cloud formation and therefore precipitation.

Answer:

The frictional force on the block is 118 N.

Explanation:

Given;

horizontal force applied on the block, f = 80 N

mass of the block, m = 20.0 kg

coefficient of friction, μ = 0.6

The frictional force on the block is calculated as;

F = μR

F = μ(mg)

F = 0.6(20 x 9.81)

F = 117.7 N

F = 118 N.

Therefore, the frictional force on the block is 118 N.

Answer:

Average Speed

If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:

[tex]\displaystyle V=\frac{d}{t}[/tex]

It's known a person runs d=15 kilometers in t=2 hours, thus his/her average speed is:

[tex]\displaystyle V=\frac{15\ km}{2\ h}[/tex]

Answer:

0.04658 m from the nut

Explanation:

Recall that torque is defined as the vector product of force (F) times distance (d). Then, given that the force is applied perpendicular to the wrench, gives the sine of the angle (90 degrees) equal to 1, simplifying the calculation which consists basically on solving for d in the equation:

2.25 N*m = 48.3 N * d

d = 2.25 /48.3  m ≈ 0.04658 m

Step 1: Define

m = 20 kg

v = 10 m/s

Step 2: Find KE

Answer:

1. Simply τ = m x g x r = 54kg x 9.8m/s² x 0.050m = 26 N·m

2. The bucket creates a torque

τ = 75kg x 9.8m/s² x 0.075m = 55 N·m,

so we must create the same torque with the handle.

55 N·m = F x 0.25m

F = 220 N
