Answer:

true..........................

Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.

As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.

Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.

The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.

The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.

Given that,

The average velocity of Ranjana, v = 3.2 m/s

We need to find how long does she take to cover a displacement  of 256 m. Let she takes t time.

We know that,

Average speed = distance/time

So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]

So, she will take 80 seconds to cover a displacement of 256 m.

But the other guy DOES NOT know how to write.

α=30°

F=20 N

Fh=F*cos(α)

Fv=F*cos(90-α)=F*sin(α) (vertical component of the force F)

Fv=20*0,5=10.00 N

Answer (C)

Answer:

impulse = 8820 kg·[tex]\frac{m}{s}[/tex] or 8820 N·s

Explanation:

Impulse J is equal to the average force [tex]F_{av}[/tex] multiplied by the elapsed time Δt or in equation form, J = [tex]F_{av}[/tex]Δt

As long as your force of 450 N is constant then that value is your average force [tex]F_{av}[/tex] and your elapsed time is 19.4 seconds.

Multiply these values.

You will get an impulse of 8820 kg·[tex]\frac{m}{s}[/tex] or 8820 N·s.

Answer:

La cantidad de globos llenos es de aproximadamente 1.974 globos

Explanation:

Los parámetros dados son;

El gas utilizado para inflar el globo = Él

El volumen del gas He, V₁ = 15 L

La presión del gas He, P₁ = 200 atm = 20,265,000 Pa

El volumen de cada globo = 1,5 L

La presión del He dentro del globo, P₂ = 770 mmHg = 102,641 Pa

Sea 'V₂', que represente el volumen total que el gas ocupa en todos los globos, y 'x', que represente el número de globos;

Por lo tanto, tenemos;

1,5 · x = V₂

Según la ley de Boyle, tenemos;

P₁ · V₁ = P₂ · V₂

∴ V₂ = P₁ · V₁ / (P₂)

Al introducir los valores conocidos, obtenemos;

V₂ = 20,265,000 Pa × 15 L / (102,641 Pa) = 2,961.53548 L

1,5 L × x = V₂

∴ 1,5 L × x = 2,961,53548 L

x = 2,961.53548 L / (1.5 L) = 1,974.35699 redondeamos hacia abajo para obtener un número entero de globos de la siguiente manera;

El número de globos, x ≈ 1,974 globos.

Answer:

[tex]\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}[/tex]

Explanation:

Velocity is found by dividing the displacement by the time.

[tex]v=\frac{s}{t}[/tex]

where s is the displacement and t is the time.

The displacement is 1.6 kilometers, but it needs a direction as well. The question notes you walked North. The time is 20 minutes.

[tex]s= 1.6 \ km \ North \\t= 20 \ min[/tex]

[tex]v=\frac{1.6 \ km \ North} { 20 \ min}[/tex]

Divide.

[tex]v= 0.08 \ km/min \ North[/tex]

Velocity is a vector quantity, so that is why it has the measurement and the direction.

The average velocity is 0.08 kilometers per minute North.

Answer:

300km

Explanation:

To find the total distance traveled within the given time frame, we need to known that distance is the product speed and time;

  Distance  = Speed x time

For the first lap:

   Distance  = 100km/hr x 3hr = 300km

For the second lap;

     Distance  = 150km/hr x 2  = 300km

Distance  = 300km + 300km

So;

Distance = 300km

D. DNA

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

Deoxyribonucleic acid (DNA) is a strand of evidence which helped to provide a link in the evolution of whales from land mammals on 4 legs to a sea mammal with fins.

Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

The object is not moving, so the net force acting on it is zero.

The two given forces act in the same direction with a total magnitude of 2 N + 10 N = 12 N.

The third force acts counter to these with some magnitude F to give a net force of 0, so that by Newton's second law

F = 12 N

Answer:

I'm fairly certain it's 1,800

Explanation:

The efficiency of the wedge with force F=900 N displaces the wedge 0.10 m is 55.55%  or 56%.

The efficiency of the machine equals the ratio of output energy and input energy. It is also defined as the ratio of work done on a load by the machine to the work done on the effort by the machine.

A load is defined as the weight lifted by the machine. The effort is defined as the force applied to bring the desired change in the load. Work done is defined as the product of force and displacement.

The efficiency, η = Output power / Input power, and the highest efficiency of the machine is equal to one. The efficiency of the machine has no unit. The efficiency η = (Actual work done / Ideal work done) × 100.

From the given,

Force = 900 N

Displacement = 0.1 m

Work done = F × s = 900×0.1 = 90 J

Actual work done = 50 J

Efficiency,η = (50/90) × 100

           η  = 55.55 %

Thus, the efficiency of the wedge is 55.56%.
