Calcule la magnitud y dirección del campo magnético que se presenta bajo una línea de transmisión de 600A, que pasa sobre el suelo a una altura h=6m, justo sobre el eje x, tal como se muestra en la figura.

Answer:

30.63 m

Explanation:

From the question given above, the following data were obtained:

Total time (T) spent by the ball in air = 5 s

Maximum height (h) =.?

Next, we shall determine the time taken to reach the maximum height. This can be obtained as follow:

Total time (T) spent by the ball in air = 5 s

Time (t) taken to reach the maximum height =.?

T = 2t

5 = 2t

Divide both side by 2

t = 5/2

t = 2.5 s

Thus, the time (t) taken to reach the maximum height is 2.5 s

Finally, we shall determine the maximum height reached by the ball as follow:

Time (t) taken to reach the maximum height = 2.5 s

Acceleration due to gravity (g) = 9.8 m/s²

Maximum height (h) =.?

h = ½gt²

h = ½ × 9.8 × 2.5²

h = 4.9 × 6.25

h = 30.625 ≈ 30.63 m

Therefore, the maximum height reached by the cannon ball is 30.63 m

Answer:

v_g,i = 1.208 m/s

Explanation:

We are given;

Mass of girl; m_g = 47.2 kg

Mass of plank; m_p = 177 kg

Let the velocity of girl to ice be v_g,i

Let the velocity of plank to ice be v_p,i

Since the velocity of the girl is 1.53 m/s relative to the plank, then;

v_g,i + v_p,i = 1.53

From conservation of momentum;

m_g × v_g,i = m_p × v_p,i

Thus;

47.2(v_g,i) = 177(v_p,i)

Dividing both sides by 47.2 gives;

v_g,i = 3.75(v_p,i)

v_pi = (v_g,i)/3.75

Thus, from v_g,i + v_p,i = 1.53, we have;

v_g,i + ((v_g,i)/3.75) = 1.53

v_g,i(1 + 1/3.75) = 1.53

1.267v_g,i = 1.53

v_g,i = 1.53/1.267

v_g,i = 1.208 m/s

Ibn Sina, also known as Avicenna, was a Persian polymath who made significant contributions to a wide range of fields, including philosophy, medicine, and science. However, his work in the field of the science of forces is not as well known as his contributions to other areas.

Ibn Sina's most significant contributions to the science of forces were in the field of mechanics, the study of motion and the forces that cause it. In his work, he described the concept of momentum, which is the product of an object's mass and velocity, and he also made important contributions to the study of the motion of projectiles.

However, it is important to note that while Ibn Sina made some important contributions to the science of forces, his work in this field was not as influential as the work of other scientists and philosophers, such as Sir Isaac Newton, who made more significant contributions to the development of the laws of motion and the theory of universal gravitation.

To change a large amount of force with a small force, you will have to apply the force over a longer period of time. So, option (a) is correct.

In physics, the term "impulse" is used to characterize or measure the impact of force operating gradually to alter an object's motion. It is often stated in Newton-seconds or kilograms per second and is denoted by the symbol J.

Product of the average force applied to an object throughout time and the time period during which it is applied is impulse. The change in momentum is the same as impulse.

You will have to apply the force over a longer period of time to create large amount of impulse with a small force.

The distance travelled by the muon is 316.8 meter, before it decays.

In radioactivity, mean life refers to the cumulative lifetime of all the nuclei of a specific unstable atomic species. This period of time can be conceptualised as the product of the lifespan of each individual unstable nucleus in a sample divided by the overall number of unstable nuclei present. A specific species of unstable nucleus's half-life is always 1.443 times shorter than its mean life.

The proper mean lifetime of a muon is 2.2 × 10⁻⁶ s.

Speed of the muon is 0.6c.

Hence, the distance travelled by the muon is = 0.6c × 2.2 × 10⁻⁶ s.

= 0.6 × 3 × 10⁸×2.2 × 10⁻⁶  meter

= 396 meter.

In relativistic observation, the distance travelled by the muon is = 396 ×√(1 - (0.6c/c)²) meter

The speed of light in MPH is 6.71×10⁸ MPH.

The speed of light is v=3×10⁸ m/s

To convert a physical quantity from meter per second to miles per hour, we need to multiply the quantity by a value of 2.237.

The coefficient of static friction places a limit of approximately 3.42 seconds on the minimum time required for the car to accelerate from rest to 60.0 mph (26.8 m/s).

To find the limit that the coefficient of static friction places on the minimum time required for a car to accelerate from rest to 60.0 mph (26.8 m/s), we need to consider the maximum acceleration the car can achieve due to the friction between the rear tires and the pavement.

The maximum acceleration can be determined using the formula:

a_max = μs * g

where μs is the coefficient of static friction and g is the acceleration due to gravity (approximately 9.8 m/s²).

In this case, since the car's engine only turns the two rear wheels, the maximum acceleration is limited by the friction force between the rear tires and the pavement.

Now, to calculate the minimum time required to accelerate to 60.0 mph (26.8 m/s), we can use the following kinematic equation:

v = u + a * t

where v is the final velocity (26.8 m/s), u is the initial velocity (0 m/s), a is the acceleration, and t is the time.

Rearranging the equation, we have:

t = (v - u) / a

Plugging in the values, we get:

t = (26.8 m/s - 0 m/s) / a_max

t = 26.8 m/s / (μs * g)

Substituting the given value for the coefficient of static friction (μs ≈ 0.800) and the acceleration due to gravity (g ≈ 9.8 m/s²), we can solve for the minimum time required:

t = 26.8 m/s / (0.800 * 9.8 m/s²)

t ≈ 3.42 seconds

Therefore, the coefficient of static friction places a limit of approximately 3.42 seconds on the minimum time required for the car to accelerate from rest to 60.0 mph (26.8 m/s).

The radius of a hemisphere with a volume of 61326 ft^3 , to the nearest tenth of a foot is 30.827 f.

The volume of a sphere with radius R is known to be:

V = (4/3)*pi*R^3

in where pi = 3.14

A hemisphere is half a sphere, its volume is half that of a sphere, and its volume is as follows for a hemisphere of radius R:

V' = (1/2)*(4/3)*pi*R^3

Now that we are aware of the volume of our hemisphere:

V' = 61326 ft^3

The equation is then easy to solve:

61326 ft^3 = (1/2)*(4/3)*pi*R^3

For R.

(We need the diameter, but knowing the radius is a good place to start because the diameter is equal to two times the radius.)

61326 ft^3 = (1/2)*(4/3)*pi*R^3

61326 ft^3 = (4/6)

*3.14*R^3

61326 ft^3*(6/4*3.14) = R^3

Answer: DADDY

Explanation:

In the case of rain, the static friction is halved, meaning the new static friction coefficient is 0.5μs, while the kinetic friction is reduced to one-third, resulting in a new kinetic friction coefficient of (1/3)μk.

To determine the maximum velocity at which you can make a turn without slipping in the rain at the intersection, we need to consider the changes in friction.

Let's assume the normal static friction and normal kinetic friction are represented by μs and μk, respectively.

In the case of rain, the static friction is halved, meaning the new static friction coefficient is 0.5μs, while the kinetic friction is reduced to one-third, resulting in a new kinetic friction coefficient of (1/3)μk.

To avoid slipping during the turn, we need to ensure that the centripetal force required for the turn is less than or equal to the maximum frictional force available.

The centripetal force is given by the equation mv²/r, where m is the mass, v is the velocity, and r is the radius of the turn.

The maximum frictional force in the rain can be calculated as (0.5μs)mg, where g is the acceleration due to gravity.

Thus, to avoid slipping, we set the centripetal force equal to the maximum frictional force:

mv²/r = (0.5μs)mg

Simplifying the equation, we find:

v = √(0.5μsgr)

By plugging in the values for μs, g, and the radius of the turn, we can calculate the maximum velocity.

Answer:

The person standing in front of the wood stove feels warmer a lot quicker than the person standing the same distance from the fire pit because of the way heat is being transferred from the fire to the person.

In the wood stove, thermal energy from the burning wood is transferred to the surrounding air, which is then forced out of the stove by convection. This convection creates a steady flow of hot air that heats up the surrounding space, including the person standing in front of the stove. This is a very efficient method of heating because the hot air is forced to circulate and distribute the heat throughout the space.

In contrast, in the fire pit, the thermal energy from the burning wood is transferred primarily by radiation. This means that the heat from the fire travels through the air in straight lines until it comes into contact with an object, like the person standing in front of the fire pit. While radiation is an effective way of transferring heat, it is not as efficient as convection because it doesn't circulate the hot air throughout the space as efficiently.

Furthermore, the wood stove is enclosed and designed to contain the heat within the stove. This means that less heat is lost to the surrounding environment and more heat is directed towards the person in front of the stove. In contrast, the fire pit is open and exposed, which means that much of the heat is lost to the surrounding environment and less heat is directed towards the person standing in front of the fire pit.

Therefore, the wood stove is a more efficient and effective method of heating because it uses convection to circulate the hot air and contains the heat within the stove, resulting in a faster and more intense warming effect on the person standing in front of it.

The efficiency of the leaf blow is 48%.
