1. a=Δv/Δt=(v-vo)/t=(0-25)/5=-25/5=-5 m/s²
The "-" sign shows us that the car has a slow motion
2.a=Δv/Δt=(v-vo)/t=(10-0)/4=10/4=2,5 m/s²
3.they do not have acceleration because they go at constant speed
Answer:
A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar aureole to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This narrow track is called the path of totality.
A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth.
Stay inside when theres lightning or try not to be the tallest object in a wide open space
Answer:
The wavelength of the given radiation is 0.327 m
Explanation:
The wavelength and the frequency of a wave are related by the formula, given below:
v = fλ
where.
v = speed of wave
f = frequency of wave = 915 MHz = 915000000 Hz
λ = wavelength of the wave = ?
For the electromagnetic radiations we know that:
v = c = speed of light = 3 x 10^8 m/s
Therefore,
c = fλ
λ = c/f
λ = (300000000 m/s)/(915000000 Hz)
<u>λ = 0.327 m</u>
Answer:
The neutron is a subatomic particle, symbol
n
or
n0
, with no electric charge and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons.[6] Their properties and interactions are described by nuclear physics.
