Answers

Answer:

 v_A = 6 m/s , v_B = 0 m/s ,  v_C = - 4 m/s , v_D = -4 m/s ,     v_E = 2.66 m / s

Explanation:

For this exercise we use the definition of average velocity in each segment

         v_average = (x₂-x₁) / Δt

 

segment A of the graph you take the value of distance and time

x₁ = 0 m     t₁ = 0 s

x₂ = 60 m   t₂ = 10 s

using the average velocity equation and calculate

         v_A = (60-0) / (10-0)

         v_A = 6 m / s

Segment B

x₁ = 60m

x₂ = 60 m

since the displacement variation is zero (particle stopped) the velocity is zero

         v_B = 0 m / s

Segment C and D

x₁ = 60 m    t1 = 15 s

x₂ = -40 m  t2 = 40 s

        v_C = (-40 -60) / (40 -15)

        v_C = - 4 m / s

Segment D

how is the same line

         v_D = -4 m / s

Segment E

x₁ = -40 m  t₁ = 40 s

x₂ = 0 m    t₂ = 55 s

         v_E = (0- (-40)) / (55 -40)

         v_E = 2.66 m / s

Three remote control cars are identical size and weight. The motors installed in the three cars are 100 watts, 150 watts and 200 watts respectively. Describe what will be true about the maximum speed of each car? Explain.

Answers

Answer:

The true statement about the maximum speed of each car will be that the power of each car directly proportional to the speed of each car.

Explanation:

Given that,

Power of first car = 100 watt

Power of second car = 150 watt

Power of third car = 200 watt

We know that,

Power :

The power is directly proportional to the cube of speed.

In mathematically,

[tex]P\propto v^3[/tex]

Where, P = power

v = speed

If the power is increased then the speed will be increase.

We need to find the maximum speed of car

According to question,

The power of car is maximum so the speed of car will be maximum.

For first car,

The power of first car is 100 watt.

So, the speed of first car will be 1000000 m/s.

For second car,

The power of second car is 150 watt.

So, the speed of second car will be 3375000 m/s.

For third car,

The power of third car is 200 watt.

So, the speed of first car will be 8000000 m/s.

Hence, The true statement about the maximum speed of each car will be that the power of each car directly proportional to the cube of speed of each car.

Sobre un cuerpo de masa 45 kg, se aplica una fuerza (F), la cual produce una aceleración cuya magnitud es 5 m -s2

Answers

Answer:

225kgm/s² or 225N

Explanation:

La fórmula de Fuerza = Masa × Aceleración

Masa = 45 kg

Aceleración = 5 m / s²

Fuerza = 45 kg × 5 m / s²

= 225 kgm / s² o 225N

Por lo tanto, la Fuerza que actúa sobre = 225 kgm / s² o 225N

Pierre cycles at 4 miles per hour and travels a distance of 13 miles. How long
does his journey take?

Answers

Answer:

His journey took him 3 hours 15 minutes.

Explanation: 4 miles every hour. So 1 hr is equal to 4 miles, 2 hrs is equal to 8 miles, 3 hrs is equal to 12 miles. Now he just has 1 miles left, and since it takes him a hour to cycle 4 miles, 60 divided by 4 is 15. Therefore, 1 mile is equal to 15 minutes.

Time = (distance) / (speed)

Time = (13 mi) / (4 mi/hr)

Time = 3.25 hr  or  3hr 15min .

Explanation:

the vacuole stores water, if it is damaged then it can store anything.

A plant cell's central vacuole has been harmed. The function largely impacted by the deterioration is water storage. Option D is correct.

What is a plant cell?

The smallest unit of all plants in the cell. Like animal cells, plant cells are eukaryotic, which means they have an organelle- and membrane-bound nucleus.

This turgor pressure maintains the cell's rigidity and gives plant structures like leaves their distinctive shapes.

When a plant goes for an extended period of time without water, the central vacuoles lose water, the cells deform, and the entire leaf wilts.

The central vacuole of a plant cell is damaged. Storage of water is the function that is most affected by the damage.

Hence, option D is correct.

To minimize damage during a broadside collision decrease the speed to put the point of impact behind the passenger section.

What is broadside collision?

A broadside collision happens when the front of one vehicle bangs into the side of another, usually at a high rate of speed. Although catastrophic injuries can occur in any automobile accident on the road, broadside crashes are especially dangerous.

This is due to the fact that there is not much room or protection between the person inside the hit automobile and the moment of contact. The injury happens to the vehicles depends on their speed.

As the speed is reduced, many such collisions can stopped in time and we can prevent broadside collision as well and giving enough time to pass other vehicles through the intersection.

why do the kites and eagles fly without flapping their wings?

Answers

Answer:

because they both have large area to capture air

Answer:

Because they have a large surface area to capture moving air when going at a certain speed.

Explanation:

When your trying to fly a kite and the wind isn't that much, you have to run so that the kite can come in contact with the fast moving air which pushes the kite to go up. Just like a eagle because when a eagle is trying to fly, it has to first flap its wings to push air downwards so that it can create lift and at a certain altitude, the eagle doesn't have to flap it's wings though it tilts its body downwards a little so that gravity can do the work, so the eagle is basically gliding downward.

A car drives 30 meters north, then turns around and drives 50 meters south. What was its distance?

Answers

Answer:

The total distance moved by the car is 80 metres

Explanation:

Given

North = 30 meters

South = 50 meters

Required

Determine the distance

Distance is a scalar quantity and hence, the total distance is the summation of distance moved in both directions

i.e.

[tex]Total\ Distance = North + South[/tex]

[tex]Total\ Distance = 30\ metres + 50\ metres[/tex]

[tex]Total\ Distance = 80\ metres[/tex]

Hence;

The total distance moved by the car is 80 metres

A man weighs 90 N on the surface of earth of radius R at what height above the surface of earth is weight will be 40 N.

Answers

Answer:

3/2 R

Explanation:

Let the Mass of man be m, Mass of earth be M.

By Newtons, law of gravitation,

F = GMm/R^2, Where G is gravitational constant

90 = GMm/R^2

When man weighs 40N,

GMm/(New R)^2 = 40

= 4/9 (90)

GMm/(New R)^2 = 4/9 (GMm/R^2)

(New R)^2 = 9/4 R^2

New R = 3/2 R

Therefore, height is 3/2 R

Answers

Answer:

8 seconds = 72cm

3 seconds = 36cm

6 seconds = 96cm

Explanation:

lab assignment i just took.

Speed is the rate of distance over time. The speed of the cart is as follows:

[tex]72cms^{-1}[/tex] at 8 seconds.[tex]36cms^{-1}[/tex] at 3 seconds.[tex]96cms^{-1}[/tex] at 6 seconds.

Let:

[tex]s \to[/tex] speed

[tex]d \to[/tex] distance

[tex]t \to[/tex] time

After 8 seconds

For low fan speed; the distance (d) at 8 seconds is:

[tex]d =576cm[/tex]

Speed (s) is calculated using:

[tex]s = \frac dt[/tex]

[tex]s = \frac{576cm}{8s}[/tex]

[tex]s = 72cms^{-1}[/tex]

Hence, the speed after 8 seconds is [tex]72cms^{-1}[/tex]

After 3 seconds

For medium fan speed; the distance (d) at 3 seconds is:

[tex]d = 108cm[/tex]

The speed (s) is :

[tex]s = \frac dt[/tex]

[tex]s = \frac{108cm}{3s}[/tex]

[tex]s = 36cms^{-1}[/tex]

Hence, the speed after 3 seconds is [tex]36cms^{-1}[/tex]

After 6 seconds

For high fan speed; the distance (d) at 6 seconds is:

[tex]d = 108cm[/tex]

The speed (s) is :

[tex]s = \frac dt[/tex]

[tex]s = \frac{576cm}{6s}[/tex]

[tex]s = 96cms^{-1}[/tex]

Hence, the speed at 6 seconds is [tex]96cms^{-1}[/tex]

A car travels north along a straight highway at an average speed of 85 km/h. After driving 2.0 km, the car passes a gas station and continues along the highway. What is the car’s position relative to the start of its trip 0.25 h after it passes the gas station?

Answers

Answer:

   x_total = 23250 m

Explanation:

This is a uniform motion exercise, the equation that describes the motion is

         v = x / t

the position is

        x = v t

let's reduce the magnitude to the SI system

        v = 85 km / h (1000 m / 1km) (1h / 3600 s) = 23.61 m / s

         t = 0.25 h (3600 s / 1h) = 900 s

let's calculate

         x₁ = v t₁

         x₁ = 23.61   900

         x₁ = 21250 m

The distance from the origin is

         x_total = x_station + x₁

         x_total = 2000 + 21250

         x_total = 23250 m

Q5: Car 1 brakes to a stop on a dry road. Car 2 does the same thing, at the same speed, on a road where it has been raining.

Answers

Answer:

1.) 4m

2.) 37 m

3.) 62m

4.) 2.5 s

Explanation:

1.) Given that the

Thinking distance = 1m

Breaking distance = 3m

Stopping distance = breaking distance + thinking distance

Stopping distance = 1 + 3 = 4m

2.) Given that the

Stopping distance = 52 m

Thinking distance = 15m

Breaking distance = 52 - 15 = 37m

3.) The stopping distance = 76m

Thinking distance = 14m

Breaking distance = 76 - 14 = 62m

It take the brakes 62m to slow the car down to a stop.

4.) Given that a lorry travels 28m when stopping from a speed of 4m/s. If its braking distance was 18m, what was the driver’s reaction time?

Thinking = stopping distance - braking distance

Thinking distance = 28 - 18 = 10m

Speed = distance/time

4 = 10/reaction time

Reaction time = 10/4

Reaction time = 2.5 s
