Answer:
The height of the building is 8,302.5 m
Explanation:
Given;
velocity of the projectile, u = 36 m/s
time of motion, t = 45 s
Let the upward direction of the bullet be negative,
The height of the building is calculated as;
![h = ut - \frac{1}{2} gt^2\\\\h = (36\times 45) - (\frac{1}{2} \times 9.8 \times 45^2)\\\\h = 1620 - 9922.5\\\\h = -8,302.5 \ m\\\\The \ height \ of \ the \ building \ is \ 8,302.5 \ m](https://tex.z-dn.net/?f=h%20%3D%20ut%20-%20%5Cfrac%7B1%7D%7B2%7D%20gt%5E2%5C%5C%5C%5Ch%20%3D%20%2836%5Ctimes%2045%29%20-%20%28%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%209.8%20%5Ctimes%2045%5E2%29%5C%5C%5C%5Ch%20%3D%201620%20-%209922.5%5C%5C%5C%5Ch%20%3D%20-8%2C302.5%20%5C%20m%5C%5C%5C%5CThe%20%5C%20height%20%5C%20of%20%5C%20the%20%5C%20building%20%5C%20is%20%5C%208%2C302.5%20%20%5C%20m)
When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption. ... In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray, for example).
Answer:
271cm^2
Explanation:
volume 1= 15^3 =3375
temp. 1. = 20+273 = 293
temp. 2. = 50+273 = 353
volume 2 =?
According to Charles law
volume is proportional to temperature
v2 = v1 * t2 / t1
v2 = 3375 * 353 / 293
v2 = 4066cm^3
v = area * length
4066 = area * 15
area = 4066/15 = 271cm^2
Answer:
Main Asteroid Belt: The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 mile) in diameter, and millions of smaller ones.
Explanation:
Well minerals are in the water we drink every Day, even the food we eat. Minerals are contained in rocks so there for both are important to life
