Convert 318 meters per second to kilometers per hour

The radius of the circular orbit should be approximately 11,582 km.

To place the spacecraft in a circular orbit about Mars with an orbital period of 8 hours and 40 minutes, the radius of the circular orbit should be approximately 11,582 km.

The radius of the circular orbit can be calculated using the formula for the orbital period of a satellite:

T = 2π√(r^3/GM)

where T is the orbital period, r is the radius of the orbit, G is the gravitational constant, and M is the mass of the central body (in this case, Mars).

Solving for r, we get:

r = (GMT^2/4π^2)^(1/3)

Substituting the given values, we get:

r = [(6.6743 × 10^-11 m^3/(kg s^2)) × (6.45 × 10^23 kg) × ((8 hours + 40 minutes) × 60 × 60 s/hour)^2 / (4π^2)]^(1/3)

Converting the time to seconds and performing the calculations, we get:

r = 11,582 km

The lateral magnification of the object is 2.

The focal length of a lens is the distance from the lens' center to the point where the light rays converge (or appear to converge).

The power of a lens is determined by its focal length. The refractive index, or the bending of light, is determined by the curvature of the lens surface.

In the given scenario, the object's distance from the convex lens (converging lens) is 10 cm and the focal length is 20 cm.

We can use the formula for lateral magnification, which is:

M = v/u

Where v is the image distance and u is the object distance.

Since the image is formed on the other side of the lens, v will be negative.

u = -10 cm, as the object is located 10 cm from the lens on the opposite side of the image.

Magnification formula:

M = v/u= (-20)/(-10)=2

The wavelength of the electron moving at 2.5 × 10^7 m/s is 2.90 × 10^-11 m.

The wavelength of an electron can be determined using the de Broglie equation: λ = h/p, where λ is the wavelength, h is Planck's constant (6.626 × 10^-34 J·s), and p is the momentum of the electron. The momentum of an object can be calculated by multiplying its mass by its velocity: p = mv, where m is the mass and v is the velocity.

So, to find the wavelength of the electron moving at 2.5 × 10^7 m/s, we need to first calculate its momentum. Using the formula p = mv, we get:

p = (9.11 × 10^-31 kg)(2.5 × 10^7 m/s) = 2.28 × 10^-23 kg·m/s

Now, we can use the de Broglie equation to find the wavelength:

λ = h/p = (6.626 × 10^-34 J·s)/(2.28 × 10^-23 kg·m/s) = 2.90 × 10^-11 m

So the wavelength of the electron moving at 2.5 × 10^7 m/s is 2.90 × 10^-11 m.

the answer is c

Explanation:

Answer: c. Weight lifting twice a week

Explanation:

Answer:

F = 987600 N

Explanation:

Force Equation

F=ma

Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.

Solve

F = m * a

F = 100 kg * 9876 m/s2

F = 987600 N

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

Kinetic energy is twice the potential energy.

A pole vaulter has kinetic energy when running forward. When a pole vaulter lowers the pole and jumps, it slows down and bends the pole. Their kinetic energy is transformed into polar elastic potential energy. When the pole is raised, the pole vaulter is lifted higher. After the start, the athlete and pole rotate around his starting box, converting some of the athlete's kinetic energy into gravitational potential energy. Also, during the jump, the momentum of the athlete causes the pole to flex, temporarily storing elastic stretch energy in the pole.

Mechanical energy depends on the position and motion of an object, and its force is the sum of kinetic energy (kinetic energy) and stored (potential) energy. That is, mechanical energy is produced when the potential energy of an object combines with its kinetic energy.

The kinetic energy of an alpha particle emitted by U-238 is 5.31315 MeV.

U²³⁸ ⇒ Th²³⁴ + He

Mass of Uranium =  238.0508 u

Mass of Thorium =  234.04359 u

Mass of alpha particle = 4.001 506  u

Δm = (Atomic mass of Thorium + Atomic mass of alpha particle - Atomic mass of Uranium)

Δm = (234.04359+4.001 506-  238.0508 )

Δm = - 0.005704

the negative sign signifies the energy is liberated.

The Kinetic energy is given by,

K.E = Δmc²

K.E = 0.005704×931.478 MeV

K.E = 5.31315 MeV

Hence, the kinetic energy of an alpha particle emitted by U-238 is 5.31315 MeV.

A 2 kg cue ball is moving at a velocity of 2 m/s when it collides with another 3 kg billiard ball at rest. The total momentum is 4 kg m/ s.

Elaborating the problem:

Before the collision, the momentum of the 2 kg cue ball is:

p₁ = m₁ × v₁

p₁ = 4 kg m/s

The 3 kg billiard ball is at rest, so its momentum is: p₂ = 0 kg m/s

The total momentum of the system before the collision is:

p_total = p₁ + p₂

p_total = 4 kg m/s

The total momentum of the system after the collision is:

p_total = M × \(V_{f}\)

p_total = p₁ + p₂

M × \(V_{f}\) = p₁ + p₂

5 kg × \(V_{f}\) = 4 kg m/s + 0 kg m/s

5 kg * \(V_{f}\) = 4 kg m/s

Therefore, \(V_{f}\) = 0.8 m/s

So, the total momentum of the system is:

p_total = M × \(V_{f}\)

p_total = 5 kg  × 0.8 m/s

p_total = 4 kg m/s

A system's total momentum is the sum of the momentum of all its components. To put it another way, it is the total amount of motion experienced by the system's objects. The total momentum of an isolated system remains constant when there are no external forces acting on it, as stated by the law of conservation of momentum.

Answer:

B. its speed increases

Explanation:

A brass rod is encased in aluminium. The speed of a sound wave in this decreases when it moves from the aluminium into the brass medium. Thus, the correct option is A.

Sound travels in different mediums in the form of waves. The speed of sound is the speed with which the sound wave travels in a medium. The speed of the wave depends on the density and the elasticity of the medium through which the sound waves travel. In general, the sound wave travels faster in the liquid mediums in comparison to the gas medium and these are quicker in solid mediums than in liquid mediums. Thus, the greater the elasticity and the lower the density of the waves, the faster the sound waves travel in that medium.

The speed of sound in aluminium is 5100m/s and in the brass medium, it is 6,923. So, if the sound wave is moving from aluminum metal to the brass medium, we can clearly observe that there is decrease in the speed of sound. So, we can say here that is the speed is decreases.

A flat slab of material with a refractive index (nm) of 2.2 and a thickness (d) of 0.35 m is exposed to a beam of light in air, which has a refractive index (na) of 1. The angle of incidence (θa) is 35 degrees with respect to the surface's normal.

Using Snell's Law, we can determine the angle of refraction (θm) within the material. Snell's Law states:
na * sin(θa) = nm * sin(θm)
1 * sin(35°) = 2.2 * sin(θm)

Solving for θm, we get θm ≈ 15.3°. This angle represents the beam of light's path within the material, deviating from the normal due to the difference in refractive indices. The slab's thickness and refractive index will affect the speed and path of the light beam as it passes through and eventually exits the material.

(a) To find the components of the vector with initial point P1 = (4, 1, -2) and terminal point P2 = (6, 1, -6), we subtract the coordinates of P1 from the coordinates of P2:

\(P2 - P1 = (6 - 4, 1 - 1, -6 - (-2)) = (2, 0, -4)\)

So, the components of the vector are (2, 0, -4).

(b) To find a unit vector with the same direction as the vector u = (7, 4, -3), we divide each component of u by the magnitude of u:

Magnitude of \(u = \sqrt(7^2 + 4^2 + (-3)^2) = \sqrt(74)\)

\(Distance =\sqrt{((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)\),

\(Distance = \sqrt{((-3 - 9)^2 + (2 - (-3))^2 + (5 - 4)^2)} = \sqrt(221)\),

(d) To find the norm (magnitude) of the vector u = (4, -3, 6), we use the formula:

\(Norm(u) = \sqrt{(x^2 + y^2 + z^2)\),

\(Norm(u) = \sqrt{(4^2 + (-3)^2 + 6^2)} = \sqrt(61)\),

The kangaroo's horizontal speed will be 9.7 m/s and its departure speed will indeed be 10.65 m/s.

By observing the pace at which this compressed region moves through the medium, we may determine the sound speed. The sound wave travels at a speed of around 343 meters per second in low humidity at 20 degrees Celsius.

The following equation relates the distance to the direction and initial velocity:

d = [v₀²sin2θ]/g, where θ – the angle of the jump.

Thus, v₀² = gd / (sin2θ) = (9.8×8)/0.69 = 113.62

v₀ = 10.65 m/s ( the take off speed).
