Spring tides occur when the Earth, sun and moon are aligned. Despite its name spring tides have nothing to do with the Spring season. It was derived from the concept of "springing-forth" . They occur at twice each lunar month, bringing higher tides during high tide and lower tides during low tide.
fulcrum to get the correct mechanical advantage?
Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is,
Distance of load from fulcrum is,
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
Therefore, the distance of load from fulcrum is 5 m.
Speed of wave depends mainly on four factors. These factors are wavelength, frequency, medium and temperature.
We know from laws of refraction, when a wave travels from rarer to denser medium, the speed of wave slows down. And when it travels from denser to rarer, it speeds up.
The relation of speed of wave with its wavelength and frequency is given by the following:
The speed of a wave in a particular medium remains constant. A higher frequency wave has shorter wavelength.
The speed of a wave also varies with temperature in a given medium. temperature affects the density of the medium and vibrations of the medium particles. Higher the temperature, higher is the speed of wave.
The factors that affect the speed of a wave are wavelength and medium. The correct option is B.
Wavelength and the characteristics of the medium a wave travels through are the two key parameters that affect a wave's speed.
Wavelength is the separation between successive wavepoints, and medium is the substance or material through which the wave is travelling, such as air, water, or solids.
The speed of the wave typically decreases as the wavelength rises. Additionally, the densities, compositions, and properties of various media can vary, which has an impact on how quickly a wave can go through them.
For instance, sound waves move through the air more quickly than they do through water. In disciplines like physics, acoustics, and communications, having an understanding of these elements is essential.
Thus, the correct option is B.

How far was the spring stretched at the moment it was released?
To find the force on the block, use Newton #1: F = m A
Force = (2.3 kg) x (0.27 m/s²)
Force = (2.3 x 0.27) kg-m/s²
Force = 0.621 Newton
The spring stretches 1 meter when to pull with 18 N of force.
To pull with only 0.621 N of force, it only has to stretch (0.621/18) of a meter. That's 0.0345 meter, or 3.45 cm .
Answer:
True
Explanation:
An optical fiber is like a glass tube with very small radius. The light travels through these fiber following Total Internal Reflection principle. The movement of the light is not affected by the external factor or the shape of the fiber as long as it is intact. Even if it is twisted or curved, the light will travel as long as the fiber is not damaged physically.
Kinetic Energy. Wind turbines convert the kinetic energy in the wind into mechanical power.
Hi Kayila :)
The best lead to describe a bacteria cell are
1) It has a cell wall
2) it has a cytoplasm
3) It doesn't have no mostly
4) It has a cell membrane
I hope that's help and have a good evening :)
