Potential energy (PE ) = m g h
Where:
m = mass = 3800 kg
g = acceleration due gravity = 10 m/s^2
h = heigth = 110 meters
Replacing:
PE = 3800 * 10 * 110 = 4,180,000 J
Answer:
3.16 ×
W/
Explanation:
β(dB)=10 × 
=
W/
β=55 dB
Therefore plugging into the equation the values,
55=10

Answer:
Vy = V0 sin 38 where Vy is the initial vertical velocity
The ball will accelerate downwards (until it lands)
Note the signs involved if Vy is positive then g must be negative
The acceleration is constant until the ball lands
t (upwards) = (0 - Vy) / -g = Vy / g final velocity = 0
t(downwards = (-Vy - 0) / -g = Vy / g final velocity = -Vy
time upwards = time downwards (conservation laws)
Answer:
gas, metal
Explanation:
The three states of by which hydrogen is found in Jupiter is made up of:
- Gaseous hydrogen
- liquid hydrogen
- liquid metal hydrogen
This is also the same states found in Saturn too.
The pressure inside the largest planet in our solar system is very great.
- Hydrogen and helium makes up the entirety of the planet Jupiter.
- It has been discovered that inside this planet, hydrogen often occurs as gas, liquid and metal
- This is often attributed to the huge amount of pressure in the planet.
Answer:
For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is.
