Sarah throws a ball directly upward at the edge of a cliff with a starting velocity of 3.0 m/s
It lands on the ground with a final speed of 6.0 m/s
How long is the ball in the air?
Round the answer to two significant digits

Answers

Answer:

The correct answer is t = 0.92s

Explanation:

Initial velocity v​0 = 3.0 m/s

Displacement Δy = ?

Acceleration a = -9.8m/s2

Final velocity v = -6.0m/s

Time t=? Target unknown

We can use the kinematic formula missing Δy to solve for the target unknown t:

V=v0+at

We can rearrange the equation to solve to t:

V-v0=at

t= v-v0/a

Substituting the known value into the kinematic formula gives:

t= (-6.0m/s)-(3.0m/s)

————————————

-9.8m/s2

= -9m/s

—————-

-9.8m/s2

=0.92s

What is the phase of water when its temperature is 150 °C?
A. Solid
B. Liquid
C. Gas
D. None of the above.

Answers

Answer:gas

Explanation:

The phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.

What are the phases of substance?

Phase is a term used in thermodynamics to describe an amount of matter that is chemically and physically uniform or homogeneous, can be mechanically separated from a nonhomogeneous mixture, and may consist of a single material or a combination of substances.

Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another.

As the boiling point of water is 100° C, the phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.

Determine the vector sum of the displacements Δd1 = 2.4 m [32° S of W]; Δd2 = 1.6 m [S]; and Δd3 = 4.9 m [27° S of E].

Answers

Answer:

3.44 metres

Explanation:

To determine the vector sum of the displacements Δd1 = 2.4 m [32° S of W]; Δd2 = 1.6 m [S]; and Δd3 = 4.9 m [27° S of E], resolve the given parameters into x - component and y - component.

Resolving into x - component

- 2.4cos32 + 4.9cos27 = 2.3306

Resolving into y - component

- 2.4sin32 - 4.9sin27 - 1.6 = - 2.553

The vector sum of the displacement will be

Sqrt( 2.3^2 + 2.6^2) =

Sqrt ( 11.81)

3.44 m

Therefore, the vector sum of the displacements is 3.44 metres

an ice cube is placed in the sun later there is a puddle of water later still the.puddle is gone what kind of change has occured​

Answers

Clear question is;

An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?

Answer:

Physical change.

Explanation:

There are two type of changes called physical change and chemical change.

In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.

Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.

A plane takes off at an angle of 30 degrees at a speed of 150 km/h. Determine the horizontal
and vertical components of this velocity vector.

Answers

Answer:

Horizontal Component = 129.9 km/h

Vertical Component = 75 km/h

Explanation:

When a vector is resolved on the x-axis and the y-axis, the components so formed are called its rectangular components. The component along y-axis is called the vertical component and the component along x-axis is called horizontal component. These components can be given by following formulae:

Horizontal Component = v Cos θ

Vertical Component = v Sin θ

where,

v = velocity = 150 km/h

θ =  angle = 30°

Therefore,

Horizontal Component = (150 km/h)(Cos 30°)

Horizontal Component = 129.9 km/h

Vertical Component = (150 km/h)(Sin 30°)

Vertical Component = 75 km/h

A 0,34-kg volleyball is flying west at 1,98 m/s when it strikes a stationary 0,60-kg basketball dead centre. The volleyball rebounds east at 0,79 m/s. What will be the velocity of the basketball immediately after impact? Choose the east direction as positive.

Answers

Explanation:

use the law of conservation of momentum

M1U1+M2U2=M1V1+M2V2

m-mass

u-initial velocity

v-final velocity

1-volleyball

2-basket ball dead center

so using the above formula

0.34×1.98+0.64×0=0.34×0.79+0.64×V2

to get

0.6732+0 = 0.2686+0.64V2

0.4046=0.64V2

divide both sides by 0.64 to get V2 which is the final velocity of basketball

0.6322m/s=V2

The final velocity of the basketball after the impact is 1.643 m/s west.

The given parameters;

mass of the volleyball, m = 0.34 kginitial velocity of the volleyball, u₁ = 1.98 m/smass of the stationary basketball, m₂ = 0.6 kgfinal velocity of the volleyball, v₁ = 0.79 m/s

The final velocity of the basketball after the impact is calculated by applying the principle of conservation of linear momentum;

m₁u₁  +  m₂u₂  =  m₁v₁   +  m₂v₂

0.34(-1.98) + 0.6(0) = 0.79(0.34) + 0.6(v₂)

-0.673 = 0.316 + 0.6v₂

-0.989 = 0.6v₂

[tex]v_2 = \frac{- 0.989}{0.6} \\\\v_2 = -1.643 \ m/s\\\\v_2 = 1.643 \ m/s \ west[/tex]

Thus, the final velocity of the basketball after the impact is 1.643 m/s west.

Answer:

Its lack of mass production

Explanation:

The limitation of using cellulose is its lack of mass production.

Cellulose is a polymer of glucose. It is obtained from glucose by condensation polymerization to yield a long chain.

Cellulose materials have a high potential of being quite useful as important materials for diverse applications.

However, the problem with cellulose materials is that they can not really be mass produced. This limitation has long encumbered the possibility of using cellulose materials for various applications in material science.

WHY DONT TWO OBJECTS MOVE TOWARDS EACH OTHER DUE TO GRAVITATIONAL PULL BETWEEN THEM

Answers

Answer:

Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

What is Justin's average velocity over the 75 s period?

Answers

Answer:

v = 1/3 m / s = 0.333 m / s

in the direction of the truck

Explanation:

The average speed is defined by the variation of the position between the time spent

           v = Δx / Δt

since the position is a vector we must add using vectors, we will assume that the displacement to the right is positive, the total displacement is

           Δx = 20 - 15 +20

           Δx = 25 m

therefore we calculate

         v = 25/75

         v = 1/3 m / s = 0.333 m / s

In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan
speeds.
What was the acceleration of the cart with Low fan speed?
cm/s2
What was the acceleration of the cart with Medium fan speed? cm/s2
What was the acceleration of the cart with High fan speed?
cm/s2

Answers

Answer:

(I).  The acceleration of the cart with low fan speed is 18 cm/s²

(II). The acceleration of the cart with medium fan speed is 23.3 cm/s²

(III).  The acceleration of the cart with high fan speed is 32 cm/s²

Explanation:

Given that,

You looked at speed-time graphs to determine the acceleration of the cart for each of the three fan  speeds in the lab.

According to graph,

A , B and shows the high, medium and low fan speeds respectively.

We know that,

The speed-time graph shows the acceleration.

Acceleration is equal to the rate of change of velocity.

(I). We need to calculate the acceleration of the cart with low fan speed

Using formula of acceleration

[tex]a_{l}=\dfrac{v_{f}-v_{i}}{t_{f}-t_{i}}[/tex]

Put the value from graph

[tex]a_{l}=\dfrac{125-0}{7}[/tex]

[tex]a_{l}=18\ cm/s^2[/tex]

(II). We need to calculate the acceleration of the cart with medium fan speed

Using formula of acceleration

[tex]a_{m}=\dfrac{v_{f}-v_{i}}{t_{f}-t_{i}}[/tex]

Put the value from graph

[tex]a_{m}=\dfrac{140-0}{6}[/tex]

[tex]a_{m}=23.3\ cm/s^2[/tex]

(III). We need to calculate the acceleration of the cart with high fan speed

Using formula of acceleration

[tex]a_{h}=\dfrac{v_{f}-v_{i}}{t_{f}-t_{i}}[/tex]

Put the value from graph

[tex]a_{h}=\dfrac{160-0}{5}[/tex]

[tex]a_{h}=32\ cm/s^2[/tex]

Hence, (I).  The acceleration of the cart with low fan speed is 18 cm/s²

(II). The acceleration of the cart with medium fan speed is 23.3 cm/s²

(III).  The acceleration of the cart with high fan speed is 32 cm/s²
