Explanation:
Gravitational force keeps it attracted to the Earth, and centripetal force keeps it moving in a circle. ... Explain how Newton's third law and his law of universal gravitation are connected. His third law states that every force has an equal opposite force attracted to it, and that force is caused by gravity.
The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.
<h3>What is meant by electromagnetic waves?</h3>
Electromagnetic waves are forms of energy that are invisible and travel throughout the universe. However, some of the effects of this energy are visible. The light that we see is a component of the electromagnetic spectrum.
Electromagnetic waves, or EM waves, are produced by vibrations between an electric field and a magnetic field. In other words, electromagnetic waves are made up of oscillating magnetic and electric fields.
<h3>How do you calculate the speed of an electromagnetic wave?</h3>
The wavelength and frequency of any periodic wave are used to calculate its speed. v = λf.
In free space, the speed of any electromagnetic wave is equal to the speed of light, c = 3 
108 m/s.
The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.

Answer:
v= 1495.04 m/s
Explanation:
The formula for velocity of sound is given by ;
v= fλ --------where
v= velocity of sound
f= frequency of turning fork
λ = wavelength
However,
Δ L = 1/2 λ ------where Δ L is spacing between resonances.
1.46 = 1/2 λ
1.46 * 2 = λ
2.92 m = λ
v= fλ
v= 512 * 2.92
v= 1495.04 m/s
Answer:
Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. ... Physical and chemical properties can be used to classify a substance as ionic or molecular.

Answer:
Aim directly at the monkey
Explanation:
Despite the mass differences, both the monkey and the food will experience the same acceleration hence while the food follows a projectile path, it will then fall and hit the monkey hence achieving the aim of feeding it. You don't need to aim below or above, aim it directly.
