Answer:

the plant died because of lack of sunlight

Explanation:

A plant gets its food from the photosynthesis process, which combines CO₂ and H₂0 into carbohydrates, the two substances are in the box, but for this they need energy from sunlight.

           CO₂ + H₂O + Sunlight /chlorophyll → (CH₂0)ₙ + O₂

the extra oxygen is released into the atmosphere.

Therefore the plant died because of lack of sunlight

Answer:

a)  a right triangle,  b)   x = 0.167 m

Explanation:

a) It is asked to find which geometry figure describes the movement of the ant.

Let's use trigonometry with the angles measured in radians

             tan θ = y / x

             tan θ = 6/10  

             θ = tan⁻¹ 0.6

             θ = 0.54 rad

this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle

b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea

            x = 0.1 / tan 0.54

            x = 0.1668 m

            x = 0.167 m

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.  

How much work did I do lifting up the ball?  As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

Answer:

C and True :)

Explanation:

Hope you got it right!

Answer:

I wanna say C

Explanation:

because A would be getting it nowhere and B would just take more time but when you use C it would be the greatest force.

Answer:

La masa del objeto es 270.027 kilogramos.

Explanation:

Asumamos que el cuerpo decelera a tasa constante, entonces podemos calcularlo por medio de la siguiente ecuación cinemática:

[tex]a = \frac{v-v_{o}}{t}[/tex] (1)

Donde:

[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.

[tex]v[/tex] - Velocidad final, en metros por segundo.

[tex]t[/tex] - Tiempo, en segundos.

[tex]a[/tex] - Deceleración, en metros per segundo al cuadrado.

Si sabemos que [tex]v_{o} = 33.889\,\frac{m}{s}[/tex], [tex]v = 13.889\,\frac{m}{s}[/tex] y [tex]t = 4.5\,s[/tex], entonces la deceleración experimentada por el cuerpo es:

[tex]a = \frac{v-v_{o}}{t}[/tex]

[tex]a = -4.444\,\frac{m}{s^{2}}[/tex]

Por las Leyes de Newton, tenemos que la masa del cuerpo se calcula a partir de la siguiente expresión:

[tex]m = \frac{F}{a}[/tex] (2)

Donde:

[tex]m[/tex] - Masa, en kilogramos.

[tex]F[/tex] - Fuerza de frenado, en newtons.

Si sabemos que [tex]F = -1200\,N[/tex] y [tex]a = -4.444\,\frac{m}{s^{2}}[/tex], entonces la masa del cuerpo es:

[tex]m = \frac{F}{a}[/tex]

[tex]m = 270.027\,kg[/tex]

La masa del objeto es 270.027 kilogramos.

An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.

Explanation:

Answer:

Law of inertia is Newton's first law of motion..

Explanation:

It means that a body will tend to be in it's motion or tend to move in a straight line unless any external force is acted upon it..

Eg: while you are travelling in bus.. If breaks are suddenly applied your body falls forward because you were in motion with bus but it tries to be in motion when breaks are applied...

Answer:

1). Average speed = 1.5 m per second

2). Average velocity = 1.5 m per second

Explanation:

1). Since, speed is a scalar quantity

   Therefore, average speed of the trip = [tex]\frac{\text{Total distance covered}}{\text{Total time taken}}[/tex]

    From the graph attached,

   Total distance covered = 10 + 10 + 20 + 0 + 20 + 30

                                           = 90 meters

   Total time taken = 60 seconds

    Average speed = [tex]\frac{90}{60}[/tex]

                               = 1.5 meter per second

2). Velocity is a vector quantity.

    Therefore, average velocity = [tex]\frac{\triangle d}{\triangle t}[/tex]

                                                   = [tex]\frac{d_{60}-d_0}{60-0}[/tex]

                                                   = [tex]\frac{90-0}{60-0}[/tex]

                                                   = 1.5 meter per second

so a A lunar phase is an angle of the moon to the earth so it appears differently every day. The moon goes through 8 major phases. A new moon is when the moon cannot be seen because we are looking at the unlit half of the Moon. The new moon phase occurs when the Moon is directly between the Earth and Sun. A solar eclipse can only happen at new moon.

Answer: The employee must do 11.2308 Joules of work

Explanation:

Work done = force × distance

But  

Force = ma(mass x acceleration due to gravity)

F = 30×9.8

F = 294N

Also distance moved can be found using  the equation  

v² = u² +2gS

1.00 ² = 0.50²+2(9.8)S

1 =0.25+19.6S

1-0.25 =19.6S

0.75=19.6S

S=0.75/19.6

S = 0.0382m

Work done = force × distance = FS

Work done = 294 N X 0.0382m

Workdone =11.2308Nm = 11.2308 Joules

Work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.

Work done is the force applied on a body to move it over a distance. Work done by a body can be given as,

[tex]W=Fd[/tex]

Here (F) is the magnitude of force and (d) is the distance traveled.

From the second law of motion, the force is product of mass time acceleration. Thus the above formula can be given as,

[tex]W=(ma)d[/tex]

For the gravitational acceleration, it can be written as,

[tex]W=(mg)d\\W=mgd[/tex]

The constant speed by which, the warehouse employee is pushing the desk across a floor is 0.50 m/s and the the final speed of the desk is 1 m/s.

Thus, the distance traveled by it can be find out using the third law of motion as,

[tex]v^2-u^2=2gd\\1^2-0.25^2=2\times9.8\times d\\d=0.0382\rm m[/tex]

As the mass of the desk is 30 kg and the distance moved is 0.382 meters. Thus, put the values in the above formula as,

[tex]W=30\times9.81\times0.0382\\W\cong11.3\rm J[/tex]

Thus the work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.

Answer:

Work is defined as force thru a distance:   W = F * S

Power is defined as Work per unit time  P = W / t

So we an write:  P = F * S / t  = 2000 N * 50 m / 5 s = 20,000 N-m/s

Since a Joule/sec is equivalent to a Watt

The power required is 20,000 Watts or 20  Kw

Also, you can convert to Hp since 1 Hp = 746 Watts

Answer:

For any v-t graph the acceleration is the slope of the graph. For average acceleration in a time period ‘t’ consider the change in velocity in time t and divide it by the time t. For instantaneous acceleration you need to go into the realm of differential calculus.

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82
