Technician A says that leather shoes offer more protection than canvas shoes. Technician B says that steel toed boots are essential to protecting your feet from injury. Which technician is correct?

A) Technician A only B) Technician B only

C) Both technicians A and B D) Neither technician A nor B

Answers

Answer: Both technicians A and B

Explanation:

Based on the scenario in the question, it should be noted that leather shoes offer more protection than canvas shoes and that steel toed boots are essential to protecting your feet from injury.

Leather shoes are more durable and offer better protection than canvas. The strength of the material that they're made from can help in offering extra protection which is necessary in an environment where there's possibility of accidents involving falling objects.

Also, for the people who work in a work environment with many heavy machines and equipments, it is vital to it on protective steel toed boots in order to prevent the workers from feet related injuries.

Can you pls answer the 2 questions

Answers

Answer:

1) False, since constant speed means constant velocity, but with constant direction as well. Velocity is speed with direction. When you move in a circle, there are boundaries which means that a constant moving speed will cause the object to veer(move in different directions) to maintain movement, If it doesn't veer, the object will deflect(rebound) off the surface due to friction, and impact force or depending on its physical bond of malleability or density.

2a) Create position vectors by drawing a ray from the center(origin) of the circle to each of your desired points, it's magnitude will be the radius(how convenient). Both of these vectors go from the center of the circle to the position on the circle. In general, the distance from the origin to a point is called the radius vector.

Which refers to the distance between two crests or two troughs on a transverse wave? wavelength amplitude frequency hertz

Answers

Answer:

Wavelength

Explanation:

The distance between two crests or two troughs on a transverse wave is known as the wavelength.

What is a wavelength?

The wavelength of a periodic wave is its spatial period or the distance over which the wave's structure repeats. It's the distance between two adjacent corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero-crossings, and it's a feature of both travelling and standing waves, as well as other spatial wave patterns.

As discussed above the wavelength, therefore, the distance between two crests or two troughs on a transverse wave is known as the wavelength.

Runner A is initially 5.8 km west of a flagpole and is running with a constant velocity of 8.6 km/h due east. Runner B is initially 4.9 km east of the flagpole and is running with a constant velocity of 7.1 km/h due west. How far are the runners from the flagpole when their paths cross? Answer in units of km.

Answers

Answer:

Runner A will be 0.05 km from the flagpole, and runner B will be 0.07 km from the flagpole

Explanation:

We can find when their paths will cross as follows:

[tex] X_{f} = X_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]

Where:

[tex]X_{f}[/tex] is the final position

[tex]X_{0}[/tex] is the initial position

v₀ is the initial speed

t is the time

a is the acceleration = 0 (since they are running with a constant velocity)

When their paths cross we have:

[tex]X_{fA}+X_{fB}=5.8+4.9=10.7 km[/tex]

[tex]V_{A}t+V_{B}t=10.7[/tex]

[tex]8.6t+7.1t=10.7[/tex]

[tex]t = 0.68 h[/tex]

Now we can find the final distance of each runner.

[tex]X_{fA}=V_{A}*0.68[/tex]

[tex]X_{fA}=8.6*0.68 km[/tex]

[tex]X_{fA}=5.85 km[/tex]

[tex]X_{fB}=V_{B}*0.68[/tex]

[tex]X_{fB}=7.1*0.68[/tex]

[tex]X_{fB}=4.83 km[/tex]

Therefore, runner A will be 0.05 km from the flagpole, and runner B will be 0.07 km from the flagpole.

what is measurement ?​

Answers

Answer: Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of measurement are dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales.

Explanation:

Measurement is a noun that shows the size and length of something established by measuring. Measurement is a unit system of measuring

A toy car, initially travelling in a straight line at 30.0 cm/s, slows down with a constant linear acceleration of 3.0 cm/s2. How much time passes before the toy car comes to a halt?

Answers

Answer:

10s

Explanation:

Given parameters:

Initial velocity  = 30cm/s

Acceleration  = 3cm/s²

Unknown:

Time it takes for the car to come to rest  = ?

Solution:

To solve this problem, we apply the right motion equation;

   Our final velocity - 0

So;

       V = U + at

Since the car is slowing down, it will have a negative acceleration

Insert the parameters and solve;

       0 = 30 + (-3) x t

          -30 = -t

              t = 10s

What affect does doubling the net force have on the acceleration of the object (when
the mass of the object stays the same)? Identify a set of two trials that support your answer to question 1

Answers

Answer: The acceleration doubles

===========================================================

Explanation:

Consider a mass of 10 kg, so m = 10

Let's say we apply a net force of 20 newtons, so F = 20

The acceleration 'a' is...

F = ma

20 = 10a

20/10 = a

2 = a

a = 2

The acceleration is 2 m/s^2. Every second, the velocity increases by 10 m/s.

---------------

Now let's double the net force on the object

F = 20 goes to F = 40

m = 10 stays the same

F = ma

40 = 10a

10a = 40

a = 40/10

a = 4

The acceleration has also doubled since earlier it was a = 2, but now it's a = 4.

---------------

In summary, if you double the net force applied to the object, then the acceleration doubles as well.

Acceleration is directly proportional to the net force on an object, and inversely proportional to its mass.

So if an object's mass stays the same while the net force on it doubles, then its acceleration will also double.

We don't know anything about the "trials".  This sounds like it might be a follow-up to a lab experiment that was performed when we weren't there.

We also don't know anything about "question 1".

A student uses two identical balls to perform an investigation. The students throws ball a with a horizontal velocity from a height of 10 meters. At the same time another students drops ball b from the same height without horizontal velocity. Neglecting air resistance what can you expect to when the balls will land?

Answers

Answer:

Both objects will land at the same time

Explanation:

The ball projected with a horizontal velocity has a vertical component of velocity which is independent of the horizontal velocity. The horizontal component of the velocity enables the ball to travel a horizontal distance, s The initial component of the vertical download velocity is zero.

Similarly, the object dropped from the height above the ground has an initial vertical velocity zero.

Neglecting air resistance, objects falling near the surface of the earth experience the same acceleration due to gravitational force of the earth, g = 9.8 meters per second squared (9.8 m/s²). So the acceleration is the same for the objects, and consequently their velocity is also increasing at a constant rate. After some time, t, both objects would have been accelerated downwards to the same extent, and would thus land at same time, t.

Complete Question  

The complete question is shown on the first and second uploaded image  

Answer:

When water is used the reading is  [tex]    R =  2281.6 \  cm  [/tex]

When mercury is used the reading is [tex]   R =  23.83 \ cm [/tex]  

The best fluid to use is mercury because for water a slight change in toluene level will cause a  large change in height .

Explanation:

From the question we are told that  

    The length of the leg of the manometer to the top of the tank is  d =  500cm

   The toluene level where in the tank where the height of the manometer fluid level in the open arm is equal to the height where the manometer is connected to the tank is  h =150 cm  

   The manometer reading is  R  

Generally at the point where the height of the open arm is equal to the height of the of the point connected to the tank ,  

   The pressure at the height of the both arms of the manometer corresponding to the base of the tank are equal  

     i.e   [tex]P_1 = P_2[/tex]

Here [tex]P_1[/tex] is the pressure of the manometer at the point corresponding to the base of the tank and this is mathematically represented as  

       [tex] P_{atm} + P_1 =  P_{atm} + P_t[/tex]

Here [tex]P_t[/tex] is the pressure due to the toluene level in the tank and in the arm of the manometer connected to the tank and this is mathematically represented as  

         [tex]P_t  =  \rho_t  * g  * h_i[/tex]

Here  

      [tex]\rho_t [/tex] is the density of toluene with value  [tex]\rho_t =  867 kg/m^3 [/tex]

       

 [tex]h_i[/tex] is the height of the connected arm above the point equivalent to the base of the tank , this mathematically represented as

          [tex]h_i =  d - h + R[/tex]

  and  [tex] P_2 [/tex] is the the pressure at the open arm of the manometer at the point equivalent to the base of the base of the tank and this is mathematically represented as

         [tex] P_2 =  \rho_f * g *  h_f [/tex]

Here  

       [tex]\rho_f[/tex] is the density of the fluid in use , if it is water the density is  

       [tex]\rho_w =  1000 \  kg /m^3 [/tex]

and  if it is  mercury the density is  

        [tex]\rho_m =  13600 \  kg /m^3 [/tex]

[tex]h_f[/tex] is the height of the  fluid in the open arm of the manometer from the point equivalent to the base of the tank which is equivalent the manometer reading R

So when the fluid is water we have

      [tex] P_{atm} +  \rho_t* g *(d - h + R) =  P_{atm} + \rho_f * g *  h_f[/tex]

=>   [tex]   \rho_t* (d - h + R) =   \rho_w *  h_f[/tex]        

=>   [tex]    867  (500 - 150 + R) =    1000 *  R [/tex]

=>    [tex]    R =  2281.6 \  cm  [/tex]

So when the fluid is mercury we have      

  [tex]   \rho_t* (d - h + R) =   \rho_m *  h_f[/tex]          

=>   [tex]    867  (500 - 150 + R) =   13600  *  R [/tex]  

=>   [tex]   R =  23.83 \ cm [/tex]  

The difference in the mercury reading for mercury due to the fact that they have different densities as we have seen in this calculation

So the best fluid to use is mercury because for water a slight change in toluene level will cause a  large change in height .

Answers

Answer:

Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
