Answer: Height of building = 17.69m, velocity of brick = 18.6m/s
Explanation: From the question, the body has a zero initial speed, thus initial velocity (u) all through the motion is zero.
By ignoring air resistance makes it a free fall motion thus making it to accelerate constantly with a value of 
.
Time taken to fall = 1.90s
a)
thus the height of the building is calculated using the formulae below
but u = 0 , hence
b)
to get the value of velocity (v) as the brick hits the ground, we use the formulae below
but u= 0, hence
find the attachment in this answer for the accleration- time graph, velocity- time graph and distance time graph
Answer:
It is called an electronic signal.
The description refers to the styloid process or tuberosity. This styloid process is seen in the 5th metatarsal and this area shows the fifth metatarsal's growth plate. This bone is being attached by strong tendon known as the <span>Peroneus brevis tendon.</span>
Electromagnetic radiation are represented in waves. Each type of wave has a certain shape and length. The distance between two peaks in a wave is called the wavelength. This value is equal to the speed of light divided by the frequency.
Wavelength = c/f
Wavelength = 3x10^8 / <span>5.42x10^15
</span><span>Wavelength = 5.54 x 10^-8 m = 55.35 nm</span>
Answer:
small marble
Explanation:
A nonpareil are confectionery tiny ball items that are made up of starch and sugar. It is very small of the size of sugar crystal or sand grains. They were the miniature version of the comfits. They are generally opaque white but bow available in all colors.
In the context, if the nucleus is compared to the size of a nonpareil then its atom would be of the size of small size marble. An atom is bigger in size than that of nucleus as the nucleus is located inside the atoms.
