How do you think the speed a satellite fall towards Earth compares to the speed it is moving forward

These tides occur twice each lunar month throughout the entire year. When the earth, moon, and sun are all in alignment, neap tides are produced by the sun's gravitational pull amplifying that of the moon.

Instead, the phrase refers to the idea of the tide "springing forth." Regardless of the season, spring tides happen twice each lunar month. Neap tides happen when the sun and moon are at right angles to one another, which also happens twice a month.

The sun, the form of the ocean, and the moon all have an impact on how much or little the tide rises or falls on Earth. Moon tides are the results of the moon's influence on the Earth's tides. The major subject of this article is moon tides.

The kinetic energy of Flying pluff is 121 KJ.

The energy that an object has as a result of motion is known as kinetic energy.  It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The body holds onto the kinetic energy it acquired during its acceleration until its speed changes. The body exerts the same amount of effort when slowing down from its current pace to a condition of rest.

Formally, a kinetic energy is any term that includes a derivative with respect to time in the Lagrangian of a system. According to classical physics, an object with mass m moving at a speed of v has kinetic energy equal to mv2.

Given that,

Average speed from home to library S₁ = 12 km/h

Average speed from library to school S₂ = 76 km/h

Total distance = 120 km

The angle and the direction of the cannonball is calculated to be about 18.435° of west.

Expressed as the ratio between two sides of a right triangle or an angle measure along with a given side, trigonometry can find unknown angle measures and lengths.

Given that,

Velocity of cannonball upward = 10 m/s

Velocity of cannonball to the west = 30 m/s

One of the side lengths reflects the velocity going north (or upward from the horizontal) at 10 m/s. Another side length depicts the speed moving west.

Angle can be calculated by applying trigonometric relation.

tan θ = northward velocity of the cannonball/westward velocity of the cannonball = 10/30

tan⁻¹(tan θ) = tan⁻¹(10/30)

θ = 18.4349°

Answer:

-3.2m

Explanation:

To find the distance of the 25N weight from the pivot, we can use the concept of moments. The moment of a force is the product of the force and the perpendicular distance from the pivot to the line of action of the force.

The total moment about the pivot due to the weights on side A is:

Moment_A = (10N * 4m) + (30N * 2m) = 80Nm

The moment of the 25N weight on side B must be equal and opposite to the total moment of the weights on side A, so we can set up the following equation:

Moment_B = -80Nm

We can solve for the distance of the 25N weight from the pivot by rearranging the equation to solve for x:

x = Moment_B / 25N = -80Nm / 25N = -3.2m

So the distance of the 25N weight from the pivot is -3.2m. This means that the weight is 3.2m to the left of the pivot, since the pivot is taken as the origin for the purpose of calculating moments.

According to the given statement The pressure exerted by the tooth is 506,315.78 Pa.

Pressure is a measure of the force exerted on a surface per unit area. It is a scalar quantity and is measured in units of force per unit area, such as pascals (Pa), pounds per square inch (psi), or atmospheres (atm).

It can be calculated using the formula:

Pressure (Pa) = Force (N) / Area (m²)

Given that the force exerted is 480 N and the area of contact with the tooth is 0.95 mm^2, we can use the formula to find the pressure exerted:

Pressure (Pa) = 480 N / (0.95 x 10⁻³ m²)

To convert mm² to m², we divide by 10⁶

Pressure (Pa) = 480 N / (0.95 x 10⁻³ m²) = 506,315.78 Pa

Hence, the pressure exerted by the tooth is approximately 506,315.78 Pa.
