Two identical containers at the same pressure contain the same gas. if container a contains half as much gas as container b, which container has the lower temperature?

The air you feel next to Earth's surface in the shade is heated by two main factors: indirect solar radiation and redirected solar radiation.

Indirect solar radiation refers to the process by which sunlight is absorbed by the Earth's surface and then re-emitted as heat. When the sun's rays reach the Earth, some of the energy is absorbed by buildings, pavement, and other objects. As these objects heat up, they release the absorbed energy as heat, which warms the surrounding air. This is why the air feels warm when you walk around the ASU Campus in the shade.

Redirected solar radiation also plays a role in heating the air near the Earth's surface. This occurs when sunlight is scattered or reflected by the atmosphere, clouds, or nearby objects, and then reaches the shaded areas. The redirected solar radiation contributes to the overall heating of the air, making it feel warm.

In conclusion, the air you feel next to Earth's surface in the shade is heated by indirect solar radiation, as the absorbed energy from the sun is released as heat, and redirected solar radiation, as sunlight is scattered or reflected and contributes to the warming of the air.

Answer:

Explanation:

Magnetic field due to current carrying wire at a distance r from the  wire is

\(B=\frac{\mu_0I}{2r}---(1)\)

In our case

\(I=\frac{I_0}{2}\)

where,

I₀ = max current or peak current

and r = h (where h is the height of power line)

\(\therefore B=\frac{\mu (I_0/2)}{2h} \\\\=\frac{\mu_0 I_0}{4h} ----(2)\)

put

h ≈ 370m

I₀ ≈ 3KA

\(B= \frac{(1.26*10^-^6)(3*10^3)}{4*(370)} \\\\=2.5*10^-^6 T\)

The required amount of power dissipated across the winding is calculated to be 60 W.

The resistance of the dc motor is given as (R) 240 ohms.

The voltage across the winding (V) is 120 v.

From ohm's law, we know that, mathematically, V = i R

Substituting the above values into the equation, we have,

V = i R

i = V/R = 120/240 = 1/2 A

The expression for power dissipated is known to be,

P = i² R

Putting the values into the above equation, we have,

P = i² R = (1/2)² 240 = 60 W

Thus, the amount of power dissipated across the winding is 60 W.

Answer:

No, because pressure is determined by force and the area over which that force acts.

Explanation:

Answer:

Pemain A

Explanation:

Mengingat data berikut;

Kecepatan pemain A = 12 m/s

Kecepatan pemain B = 36 km/h

Untuk menentukan siapa pelari tercepat di antara dua pemain;

Pertama-tama, kita harus mengubah kecepatan menjadi satuan standar pengukuran yang sama.

Jadi, mari kita gunakan pengukuran umum meter per detik.

Konversi:

36 km/h = (36 * 1000)/(60 * 60)

36 km/h = 36000/3600

36 km/h = 10 m/s

Kecepatan pemain B = 10 m/s

Oleh karena itu, dibandingkan dengan kecepatan pemain A; pemain A lebih cepat.

When a ladder with 20 ft. long is pulled along the floor away with a constant rate 1.2 ft/s, then the top of the ladder is moving toward the floor with velocity - 0.9 ft/s and there is no acceleration.

Let:

x = the distance between the bottom of the ladder from the wall

y =  the distance between the top of the ladder from the floor

When x = 12 ft, then using the Pythagorean Theorem:

x² + y² = 20²    (Equation 1)

12² + y² = 20²

y² = 20² - 12² = 16²

y = 16 ft.

Take the derivative of equation 1 with respect to t

2x . dx/dt + 2y. dy/dt = 0

Substitute x = 12, y = 16, dx/dt = 1.2 ft/s

2 . 12 . (1.2) + 2 . 16 . dy/dt = 0

dy/dt = - 0.9 ft/s

Hence, the velocity is - 0.9 ft/s

Since the floor is moving with a constant rate, the acceleration is zero.

The weight of a 75 kg person on Earth is 735 N, The correct option is D.

Acceleration due to gravity is the acceleration that an object experiences due to the gravitational force exerted by a massive body, such as Earth. The acceleration due to gravity on Earth is approximately 9.8 meters per second squared (m/s^2) and is denoted by the symbol "g".

The acceleration due to gravity is a vector quantity, which means that it has both magnitude and direction. The direction of the acceleration due to gravity is always downwards, towards the center of the massive body.

The acceleration due to gravity is a constant value near the surface of the Earth, but it can vary slightly depending on altitude, latitude, and the composition of the Earth's interior. For example, at higher altitudes, the acceleration due to gravity decreases slightly, while at the equator, it is slightly greater than at the poles due to Earth's rotation.

The acceleration due to gravity plays an important role in many physical phenomena, including free fall, projectile motion, and the behavior of fluids in containers.

Here in the Question,

The weight of a 75 kg person on Earth can be calculated using the formula:

weight = mass x acceleration due to gravity

Substituting the given values, we get:

weight = 75 kg x 9.8 m/s^2

weight = 735 N

Therefore, the weight of a 75 kg person on Earth is 735 N, which is option D.

A preserved quantity is momentum. Snowball and skater's initial system momentum is 0 because everything is motionless. A snowball must have zero motion overall after being thrown. To make the skater's momentum equal zero, she skates backward (in the opposite direction of the snowball).

The conservation of momentum is a general law of physics which states that the total momentum of a system remains constant and that the quantity called momentum which characterizes motion never changes in an isolated collection of objects. Momentum is the force necessary to bring an item to a complete stop in a unit of time, and is determined by multiplying an object's mass by its velocity.

The total momentum is equal to the sum of the individual momenta for any array of multiple objects. The momenta of objects moving in opposite directions might cancel out to produce an overall sum of zero, due to the oddity that momentum is a vector that includes both the direction and the amplitude of motion.

It is observed that the time for the ball to strike the ground at B is 2.5 s. the speed (magnitude of initial velocity) of the ball is approximately 7.873 m/s, and the angle (measured below the horizontal) at which the ball was thrown is approximately -39.31 degrees.

To determine the speed and angle at which the ball was thrown, we can use the equations of motion for projectile motion.

Let's start by calculating the initial horizontal velocity (v₀x) of the ball. We know that the horizontal distance traveled (range) is 50 ft, which is equivalent to 15.24 meters.

Range = v₀x × time

15.24 = v₀x × 2.5

v₀x = 15.24 / 2.5

v₀x = 6.096 m/s

Next, let's calculate the initial vertical velocity (v₀y) of the ball. We can use the equation for vertical displacement:

Vertical displacement = v₀y × time + (1/2) × acceleration due to gravity × time²

Since the ball starts and lands at the same vertical position (1.2 meters), the vertical displacement is zero. We can rearrange the equation to solve for v₀y:

0 = v₀y × 2.5 + (1/2) × 9.8 × (2.5)²

0 = 2.5v₀y + 12.25

v₀y = -12.25 / 2.5

v₀y = -4.9 m/s

Note that the negative sign indicates that the initial vertical velocity is directed downwards.

Now, we can calculate the magnitude of the initial velocity (v₀) using the horizontal and vertical components:

v₀ = sqrt(v₀x² + v₀y²)

v₀ = sqrt((6.096)² + (-4.9)²)

v₀ = sqrt(37.179056 + 24.01)

v₀ ≈ 7.873 m/s

Finally, we can calculate the angle (θ) at which the ball was thrown using the inverse tangent function:

θ = arctan(v₀y / v₀x)

θ = arctan(-4.9 / 6.096)

θ ≈ -39.31 degrees (measured below the horizontal)

Therefore, the speed (magnitude of initial velocity) of the ball is approximately 7.873 m/s, and the angle (measured below the horizontal) at which the ball was thrown is approximately -39.31 degrees.

Answer:

x = 100.64 [m]

Explanation:

To solve this problem we must use the following kinematics equation.

\(v_{f} = v_{i} + (a*t)\\\)

\(v_{f} ^{2} = v_{i} ^{2} + (2*a*x)\\\)

where:

Vi = initial velocity [m/s]

Vf = final velocity = 60.16 [m/s]

a = acceleration = 17.98 [m/s^2]

t = time = 7 [s]

Now replacing the values, we have:

(60.16)^2 = 0 + (2*17.98*x)
