The Available options are:

A. Award an indirect free kick to Team B for incidental contact.

B.  Award a direct free kick to Team B.

C.  Allow play to continue as the handling was incidental but issue a caution to the player at the next stoppage of play.  

D.  Allow play to continue.

Answer:

Allow play to continue.

Explanation:

IFAB (International Football Association Board) has approved various means to clarify the issue of handball in foodtball.

Hence, some of the cases include:

1. Should the the ball touches a player's hand/arm immediately from their own head/body/foot or the head/body/foot of another player.

2. the ball touches a player's hand/arm close to their body and has not made their silhouette unnaturally bigger.

3. a player is falling and the ball touches their hand/arm when it is between their body and the ground (but not extended to make the body bigger).

4. Additionally, should the goalkeeper attempt to clear a ball from a teammate but fails, the goalkeeper is allowed to handle the ball.

Hemce, Since a14 who did not see the ball coming and the ball strikes her in the back of the hand as her hand is at her side. the proper call would be to: ALLOW PLAY CONTINUE

Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass 5.00 ✕ 10-5 kg hangs motionless on it.
Mandarinka [93]

Answer:

4.9 x 10⁻⁴N

Explanation:

Given parameters:

Mass of the vertical strand of spiderweb  = 5 x 10⁻⁵kg

Unknown:

Tension in the vertical strand  = ?

Solution:

The tension is the vertical strand will be the weight of the strand.

  Weight of strand  = mg

m is the mass

g is the acceleration due to gravity = 9.8m/s²

Tension in the vertical strand  = 5 x 10⁻⁵kg  x 9.8m/s²

Tension in the vertical strand  = 4.9 x 10⁻⁴N

What is the total current in the circuit? (must include unit - A) REWARD = BRAINLEST
Aleksandr-060686 [28]

Answer:6amperes

Explanation:

1/R=1/40 + 1/40

1/R=2/40

Cross multiplying we get

2R=40

Divide both sides by 2

2R/2 =40/2

R=20ohms

Current=voltage ➗ resistance

Current=120 ➗ 20

Current =6amperes

A decorative plastic film on a copper sphere of 10 mm diameter in an oven at 750C. Upon removal from the oven, the sphere is sub
AlladinOne [14]

Answer:

3.26 secs

Explanation:

Diameter of sphere ( D )= 10 mm

T1 = 75°C

P = 1 atm

T∞ = 23°C

T2 = 35°c

Velocity = 10 m/s

<u>Determine how long it will take to cool the sphere to 35°C</u>

<em>Using the properties of copper and air given in the question</em>

Nu = 2 + (Re)^0.8 (Pr)^0.33

hd / k = 2 + ( vd/v )^0.8 (Pr)^0.33

∴ h ≈  2594.7 W/m^2k

Given that :

(T2 - T∞) / ( T1 - T∞ )  = exp [ ( -hA / pv CP ) t ]  

( 35 - 23 ) / ( 75 - 23 ) = exp [  - 2594.7 * 6 * t / 8933 * 387 * 10 * 10^-3 ]

=  ln ( 12/52 ) = -1.466337069  =     - 0.45032919 *  t

∴ t ≈ 3.26 secs        ( -1.466337069 / -0.45032919 )

Como anticipan la caída del proyectil, con movimiento parabólico para que el misil no haga daño
Elena L [17]

Answer:

Conociendo la velocidad inicial del proyectil y el angulo de lanzamiento con respecto ala horizontal.

Explanation:

Para poder anticipar la caída del proyectil es importante conocer la velocidad inicial del proyectil y el angulo de disparo del proyectil con respecto a la horizontal.

A continuación se presenta un diagrama o esquema donde se pueden ver estas variables y se explicaran a la brevedad:

Para poder encontrar el rango que es la máxima distancia horizontal recorrida por el proyectil debemos utilizar la siguiente ecuación:

x=(v_{o})_{x} *t\\where:\\(v_{o})_{x} = velocidad inicial  x-component [m/s]\\t= time [s]

Para poder encontrar el tiempo debemos utilizar la siguiente ecuación:

y=(v_{y} )_{o}*t-0.5*g*t^{2}  \\donde:\\(v_{y} )_{o}= velocidad inicial componente y [m/s]\\g = gravity = 9.81 [m/s^2]\\t = time [s]

En la anterior ecuación, igualamos y = 0, ya que cuando el proyectil cae al suelo la distancia vertical es cero. De esta manera podemos encontrar el tiempo t, ya que conocemos la velocidad inicial del proyectil en la componente y.

Seguidamente reemplazamos t en la primera ecuacion y encontramos la distancia x o el rango.
