The ratio of the orbital period of planet B to that of planet A is T_B/T_A = Squareroot 8.

A planet is an astronomical object that orbits a star and does not produce its own light. The vast majority of the thousands of objects we call planets orbit a star in our Solar System. This specific system includes the sun and the eight planets that orbit around it.

Two planets A and B, where B has twice the mass of A, orbit the Sun in circular orbits. The radius of the circular orbit of planet B is two times the radius of the circular orbit of planet A. The formula for calculating the time period of a circular orbit is:

T = (2πr) / v

where, r = radius, v = velocity

For circular orbits, T ∝ (r³/²)

Therefore, T_B/T_A = (r_B³/²) / (r_A³/²)T_B/T_A = (2³/²) / 1³/2T_B/T_A = (square root 8)/1T_B/T_A = Squareroot 8.

Therefore, the ratio of the orbital period of planet B to that of planet A is T_B/T_A = Squareroot 8.

If a powerful motorcycle can reach 13.57m/s² (58 mi/h) from rest in under 1.90 seconds, its average acceleration is 4.20 m/s2, and it will travel 24.51 m.

The rate at which velocity varies is termed acceleration. Acceleration usually signifies a shift in speed, but not usually. An item that follows a circular course while maintaining a constant speed is still moving forward as the direction of its motion is fluctuating.

given,

initial speed,u = 0 m/s

final speed,v = 25.8 m/s

time, t= 1.90 s

a) acceleration,

a =  v-u/t

a = 25.8-0/1.90

a = 13.57 m/s²

(b) distance to travel in that time

using equation of motion

v² = u² + 2 as

  25.8² = 0² + 2 x 13.57 x s

      13.57 s = 332.7

         s = 24.51 m

the motorcycle will travel 24.51 m

Explanation:

The interstellar medium (ISM) is the material between stars in a galaxy, composed of approximately 99 percent gas and 1 percent dust. However, it is the dust that can block our view of the galactic center in certain kinds of light. Regarding the effect of dust blocking our view of the galactic center, statement C is not true.

This is because dust grains are better at absorbing and scattering light than gas molecules. Dust can absorb and reflect light differently depending on its composition and the wavelength of the light. For example, shorter wavelengths are more easily scattered by dust, making it appear more visible in blue light. Additionally, dust can absorb certain wavelengths, such as infrared light, which can make it difficult to observe certain objects behind the dust.Therefore, statement C is not entirely accurate as dust can absorb and reflect light in different ways depending on various factors. It is important to study the properties of the ISM and understand how different components can impact our observations of the galaxy.

Answer: 510 in Newton’s and 115 lbs

Explanation:

Considering the definition of weigh, Lisa weighs 0.5096 N or 0.1146 pounds.

Mass is the amount of matter that a body contains, while weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

Weight can be calculated as the product of mass and acceleration due to gravity:

W=m×g

In this case, you  know:

Replacing in the definition of weigh:

W=0.052 kg×9.8 m/s²

Solving:

W= 0.5096 N

1 newton equals 0.2248 pound. Then W=0.5096 N= 0.1146 Pounds

Finally, Lisa weighs 0.5096 N or 0.1146 pounds.

The tangent of the angle at which the items slide equals the coefficient of static friction. The measurement of k can be done in a similar way. To accomplish it, push the upper object while angling it upward. The tangent of that angle equals k when the upper object slides along at a constant speed.

Why is the coefficient of static friction determined using an incline?

By calculating the angle at which the force of gravity overcomes the static friction, you can utilize an item that is inclined to calculate the static coefficient of friction.

How can you tell which way static friction is prevailing?

Static friction pushes in the direction you're trying to travel when you walk (see Figure 2 below). In the absence of friction, the foot would slip backwards as it presses on the ground (like walking on ice).

Given

d: diameter

d = 41 cm

We need radius information so we will calculate it:

r: radius

r = d/2

r = 41/2

r = 20.5 cm

Rotating speed

w = 242 rpm

Procedure

At a distance r from the center of the rotation, a point on the object has a linear speed equal to the angular speed multiplied by the distance r. The units of linear speed are meters per second, m/s.

But before using the formula we need to have all the units in the same system. So we need to go from rpm to rad/s and from cm to m

Now we can calculate the linear velocity of the belt.

While spinning down from 500.0 rpm to rest, a solid uniform flywheel does 6.2 kJ of work. If the radius of the disk is 1.2 m, its mass is 3.14 kg.

Given,

radius of the disk (r) = 1.2 m

Total work done in spinning down to rest (W) = 6.2 kJ =6200 J

Initial angular speed (ω) = 500 rmp = \(500*\frac{2\pi}{60} rad/s\) = 52.36 rad/s

Let the mass of the disk = m

∴ Initial linear velocity (v) = ωr = 52.36×1.2 =62.83 m/s

As the disk comes to rest in end, hence final linear velocity = 0

∴ Change in kinetic energy = Total work done

⇒\(\frac{1}{2}mv^{2} - 0= W\)

⇒\(m=\frac{2W}{v^{2}}\)

⇒\(m=\frac{2*6200}{(62.83)^{2}} =3.14 kg\)

Therefore the mass of the disk is 3.14 kg.

Answer:

Explanation:

The gravitational force between two objects can be calculated using the formula:

F = G * (m1 * m2) / r^2

Where F is the gravitational force, G is the gravitational constant (6.67 x 10^-11 Nm^2/kg^2), m1 is the mass of one object (60 kg), m2 is the mass of the other object (5.67 x 10^26 kg), and r is the distance between the two objects (the radius of Saturn, 6.3 x 10^7 m).

F = 6.67 x 10^-11 * (60 * 5.67 x 10^26) / (6.3 x 10^7)^2

F = 6.67 x 10^-11 * 3.402 x 10^33 / 3.969 x 10^14

F = 2.30 x 10^19 N

So the gravitational force on a 60 kg man on Saturn would be approximately 2.30 x 10^19 N.

The ship is located 200.51 km east from the harbor.

The given angle of travel of the ship is 27.5° to the south of due east. To solve this question, we can use trigonometry, and more specifically, we can use the sin function because we know the opposite and hypotenuse side of the angle of travel of the ship. To get started, we need to break down the angle of travel as well as the displacement of the ship along the eastern axis. We know that the ship sailed at 27.5° to the south of due east and traveled a distance of 365 km. From this information, we can find the opposite and hypotenuse side of the triangle formed by the ship's angle of travel and displacement eastward. Let x be the displacement of the ship along the eastern axis.

Then, east displacement of ship = x

We know that the angle of travel of the ship = 27.5° south of due east. This implies that angle of travel of the ship from the eastern axis is 90° - 27.5° = 62.5°.

We know that opposite side of the ship's angle of travel is the southward displacement of the ship = 365 km.

This implies that the hypotenuse of the ship's angle of travel is given as: hypotenuse = 365 / sin(62.5°) = 398.89 km

Therefore, the displacement of the ship along the eastern axis = east displacement of the ship = hypotenuse × cos(62.5°)

Substituting hypotenuse = 398.89 km and angle of travel of ship from eastern axis = 62.5°, we get:

east displacement of ship = 398.89 × cos(62.5°) = 200.51 km

Therefore, the ship is located 200.51 km east from the harbor.

The average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate. This occurs when the concentration of reactants is constant, and there is no change in the reaction mechanism or conditions.

The average rate of a reaction is calculated by dividing the change in the concentration of the reactants by the time taken for that change to occur. On the other hand, the instantaneous rate of a reaction is the rate at which the reaction is occurring at a particular point in time.

When the reaction is happening at a constant rate, the average rate and the instantaneous rate are the same at any given second. This means that the rate of the reaction does not change over time, and the concentration of the reactants is constant. However, in most cases, the reaction rate changes over time, and the instantaneous rate at any given second is not equal to the average rate.

In conclusion, the average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate.
