Answer:

d = 4.44 m

Explanation:

Given that,

The moment of force on a door = 10 N-m

The applied force, F = 2.25 N

We need to find the distance of the handle. The moment of force is given by :

[tex]\tau=F\times r[/tex]

Where

r is the distance of the handle.

[tex]r=\dfrac{\tau}{F}\\\\r=\dfrac{10}{2.25}\\\\r=4.44\ m[/tex]

So, the required distance is equal to 4.44 m.

Answer:

117.43 m

Explanation:

Eg=mgh=13x9.81xh=127.53h(N)

Ek=0.5mv^2=0.5(13)(48)^2=14,976 N

by conservation of potenial energy:

Ei=Ef

127.53h=14976

h=117.43m

The surface of Mercury looks much like Earth's moon. ... On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm. The temperature can drop down to minus 300 degrees Fahrenheit. Sunlight never reaches into the bottoms of some craters near Mercury's poles.

Answer: B

Because Mercury is the closest planet to the sun

Answer:

101201.2 Pascal.

Explanation:

Given that the difference h between the two liquid levels is 2.0 cm. The density of the liquid is 800 kg /m3.

Calculate the difference between the pressure of the gas and atmospheric

pressure.

The pressure of the gas can be calculated by using the formula

Pressure = density × acceleration due to gravity × height

Substitute all the parameters into the formula

Pressure = 800 × 2/100 × 9.8

Note that the height is converted to metre.

Pressure = 156.8 Pascal

pressure difference = 101358 - 156.8

Pressure difference = 101201.2 Pascal

Explanation:

Bauxite is the primary mineral from which aluminum is produced. The ore must first be cleaned before the metal can be electrolytically reduced out of it. Thus, option A is correct.

Bauxite normally has a Mohs hardness of 1 to 3 and is a soft substance. Its color ranges from white to gray to reddish-brown and has a pisolitic structure. It also has an earthy gloss and a specific gravity of 2.0 to 2.5. These characteristics help distinguish bauxite, although they have no bearing on its worth or potential uses.

Typically, aluminum is manufactured in regions with relatively low electricity costs. An abrasive substance is bauxite.

Therefore,  Bauxite is crushed to a fine powder and then fused at a very high temperature to form spherical beads, creating sintered bauxite, which is frequently used as a sand-blasting abrasive.

Explanation:

point c is minimum Amplitude in transversal wave

Answer:

Time, t = 7 seconds.

Explanation:

Given the following data;

Initial velocity = 0m/s (since it is starting from rest).

Acceleration, a = 4 m/s²

Final velocity, v = 28 m/s

To find the time, we would use the first equation of motion given by the formula;

V = u + at

Substituting into the formula, we have;

28 = 0 + 4*t

28 = 4t

Time, t = 28/4

Time, t = 7 seconds.

Answer:

25 m

Explanation:

The submarine dives at angle of 30 degree with the horizontal . It has travelled 50 m at this angle . So , it will have both 25 horizontal as well as vertical displacement below the surface .

vertical displacement below the surface = vertical component of displacement of 50 m

= 50 sin30

= 25 m .

Depth of submarine below the surface = 25 m.

Answer: 1.79 kW

Explanation:

Given

The temperature of the refrigerator is [tex]T_L=2^{\circ}C\approx 275\ K[/tex]

The temperature of the kitchen is [tex]T_H=22^{\circ}C[/tex]

COP of the refrigerator is

[tex]COP=\dfrac{T_L}{T_H-T_L}=\dfrac{\text{Desired effect}}{\text{Power}}\\\\\Rightarrow COP=\dfrac{275}{22-2}=\dfrac{89}{P}\\\\\Rightarrow P=\dfrac{20}{275}\times 89=6.47\ MJ/h\ \text{or}\ 1.79\ kW[/tex]

A constant force of 1.25N

Explanation:

This is a kinematics problem.

First find acceleration,

then use F = ma to find force.

Given:

mass = .5kg

delta x = 20m

t = 4s

a = ?

Friction = 0

From the kinematics equations:

delta x = Vi + (1/2)at^2

Plug in terms that are given:

20m = 0 + (1/2)a(4^2)

(2*20m)/(16s^2) = a

40m/(16s^2)= 2.5m/s^2

Now use F = ma to find force exerted on object.

F = (0.5kg)*(2.5m/s^2)

F = 1.25N

Answer: It is trusted that the sum of all forces acting on the student, adds up to zero the student is not moving.

Explanation: the plane they give you that the plane is moving at a constant velocity of 250 m/s this means that the acceleration is zero, we substituted in the formula F=ma which will give us the Force. And knowing that its constant speed, forward force is then equal to the Air resistance. Hence we find the Air resistance force
