Answer:
Hydrogen nuclei fuse to form a larger nucleus, and a small amount of mass is converted into energy.
Answer:
rainbow is regarded as one of the most spectacular light shows observed on the earth. A rainbow is a multicoloured arc made due to the striking of light on water droplets. Rainbow is produced after the rain, by reflection, refraction and light dispersion process in droplets of water. All such events develop a light spectrum in the sky are called rainbow.
The necessary conditions for the formation of the rainbow:
Presence of raindrops.
Sun should be at your back to observe the rainbow
Because of the dispersion, white light separates into different colors when entering the raindrop, causing less refraction of red light than blue light.
Formation of the rainbow:
Light rays, reach the drop near its top level. At first, there is refraction, then the dispersion of white light into colours of a different wavelength.
The violet is the most deviated and red is the least deviated colour.
Reaching the opposite side of the drop, each colour is refracted back into the drop due to the complete internal reflection that hits the drop surface.
Every colour is refracted to the air again.
We experience the rainbow when we observe in between 42-40 degrees.
Im pretty sure its called a tendon. :/
Answer:
The wavelength of WFNX’s radio waves with the given speed and frequency is 2.95m.
Given data in the question;
Speed of wave;
Frequency of wave;
wavelength;
To determine the wavelength of the radio wave, we use the expression for the relations between wavelength, frequency and speed.
Where is wavelength, f is frequency and c is the speed.
We substitute our given values into the equation
Therefore, the wavelength of WFNX’s radio waves with the given speed and frequency is 2.95m.
Explanation:
The time of flight depends only on the initial velocity and the initial height
Explanation:
An object is said to be in free fall if the only force acting on it is the force of gravity. If this is the case, then the motion of the object in free fall is a uniformly accelerated object, with constant acceleration towards the ground. The time of flight can be found by using the suvat equation:
where
s is the displacement (which corresponds to the initial height of the object)
u is the initial vertical velocity
is the acceleration
t is the time of flight
Therefore, from the equation, we see that the time of flight depends only on two factors:
- s, the initial height of the object
- u, its initial velocity
In case the air resistance is not negligible, then the acceleration is no longer constant, and the time of the fall also depends on other factors such as the mass of the object and its shape, which affects the magnitude of the air resistance acting on the body.
