The correct answer is option C.

Maxwell right hand thumb rule: if we hold a current carrying conductor in our right hand such that the thumb indicates the direction of current then the curling of fingers shows the direction of magnetic field around the conductor.

Here the current is counterclockwise so by use of Maxwell right hand thumb rule the direction of magnetic field is straight up.

Using Fleming right hand rule that States that if the fore-finger, middle finger and the thumb of left hand are stretched mutually perpendicular to each other, such that fore-finger points in the direction of magnetic field, the middle finger points in the direction of the motion of positive charge, then the thumb points to the direction of the force.

So, the current, when viewed from above, seems to move around loop in counterclockwise direction points straight up is because of Maxwell's Thumb Rule.

If a star has a parallax of 0.050 arc second, what is its distance in pc? In ly? In AU? Seeds, Michael A.. Universe: Solar Syste
vaieri [72.5K]

Answer:

Distance in pc= 20parsecs

Distance in zLY= 65.2LY

Distance in AU= 4.1×10^6AU

Explanation:

Using the formular:

d = 1/p

Where d = distance

P= parallax angle in arc of second

d= 1/0.050

d= 20 parsed

Converting to Lighy years,LY :

1 PC = 3.26LY

d= 20pc × (3.26Ly/1pc)

d= 65.2Ly

To convert to AU, 206,265 AU = 1pc

d= 20pc × (2.06×10^5AU/1pc)

d= 4.1×10^6AU

Two boxers are fighting. Boxer 1 throws his 5 kg fist at boxer 2 with a speed of 9 m/s.
Sladkaya [172]

Answer:

0.001 s

Explanation:

The force applied on an object is equal to the rate of change of momentum of the object:

F=\frac{\Delta p}{\Delta t}

where

F is the force applied

\Delta p is the change in momentum

\Delta t is the time interval

The change in momentum can be written as

\Delta p=m(v-u)

where

m is the mass

v is the final velocity

u is the initial velocity

So the original equation can be written as

F=\frac{m(v-u)}{\Delta t}

In this problem:

m = 5 kg is the mass of the fist

u = 9 m/s is the initial velocity

v = 0 is the final velocity

F = -45,000 N is the force applied (negative because its direction is opposite to the motion)

Therefore, we can re-arrange the equation to solve for the time:

\Delta t=\frac{m(v-u)}{F}=\frac{(5)(0-9)}{-45,000}=0.001 s

1. The center of gravity of both cats and humans is roughly in the thoracic region. However, they each bear their weight very di
Mama L [17]

Answer:

Major, weight-bearing structures are the bones of the body that are strong and dense to be able to bear the weight of the body. The major, weight-bearing structures of cat and human skeletons are :

Human skeleton: The body weight of an individual is on his pelvic girdles that are attached to the bones of lower limbs. Thigh bones, leg bones, and bones of feet comprise lower limbs The lower limbs consist of the thigh, the leg, and the foot.

Cat skeleton:  cats are quadrupedal so it bears all the body weight on shoulders and legs that includes the Scapula and pelvis.
