The area vector of a square loop of 5 turns of a conductor each with side length of 0.2 m carrying a current of 2 A is antiparal
lord [1]

Answer:

the magnitude and the direction of the total magnetic field is 0.4 Am²  antiparallel to the area vector

Explanation:

Given that:

The area vector of a square loop  has 5 numbers of turns i.e n = 5

each with side length = 0.2 m

Current I = 2 A

uniform magnetic field =  50.0 T

Now; the magnitude of the total magnetic field B is calculated as :

B = IA

where;

I = current

A = area ( n × l²)  

B = I ( n × l²)

B = 2 ×  5 ×  0.2²

B = 0.4 Am²

The direction of the magnetic moment is antiparallel to the area vector;

Hence ; the magnitude and the direction of the total magnetic field is 0.4 Am²  antiparallel to the area vector

an object has a constant acceleration of 3.2 m/s^2.at a certain instant its velocity is 10 m/s . what is its velocity after 5 se
aleksandrvk [35]

So here, you're looking for distance. The formula is D=vt+1/2at^2.

Lets plug in the informations.

10 m/s is our v (initial velocity)

5 second is out t(time)

3.2 m/s is our a(acceleration)

10m/s(5)+1/2(3.2m/s+5^2)

50m/s+1/2(28.2)

50m/s+14.1

Answer =64.1 m

Glad to help you out buddy. Let me know if you need help.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?
Paul [167]

It's easy to roll the the basket ball than bowling ball

It is because bowling ball is solid spherical ball which will have less moment of inertia

its moment of inertia is given as

I = \frac{2}{5}mR^2

While for the hollow ball like basketball we know that moment of inertia is given as

I' = \frac{2}{3}mR^2

so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.

So it is easy to roll basket ball then rolling ball

A ball on the end of a string is revolving at a uniform rate in a vertical circle of radius 97.7 cm. If its speed is 3.74 m/s, a
noname [10]

The tension in the string when the ball is at the bottom of the path is 2.61 Newtons.

<h3>Tension</h3>

A tension is simply referred to as a force along the length of a flexible medium such as strings, cable, ropes etc.

Tension in a string revolving can be determined using the expression;

T = mv² / r

Where m is mass of object, v is velocity and r is radius ( length of string )

Given the data in the question;

  • Mass of ball m = 0.182kg
  • Radius ( length of string ) r = 97.7cm = 0.977m
  • Velocity = 3.74m/s
  • Tension in the string; T = ?

To determine tension in the string, we substitute our given values into the expression above.

T = mv² / r

T = (0.182kg × (3.74m/s)²) / 0.977m

T = (0.182kg × 13.9876m²/s²) / 0.977m

T = (2.5457432kgm²/s²) / 0.977m

T = 2.61kgm/s²

T = 2.61N

Therefore, the tension in the string when the ball is at the bottom of the path is 2.61 Newtons.
