Answer:
Explanation:
firstly we have to find the frequency and then the angular frequency.
The frequency will be:
The angular frequency is:
ω
ω
ω
Now we can apply simple pendulum relationship
ω
make g the subject of the formula
Kinetic energy = 1/2 x mass x velocity²
10.0km x 100 = 10000m
Kinetic energy = 1/2 x 100 x 10000²
Kinetic energy = 5000000000J
Answer:
Explanation:
There is a chemistry category, but:
find the ratio by dividing by smallest value:
find and balance chemical formula:
2 molO and 1 mol C is needed for a complete reaction, therefore the limiting reactant is the O
solve for CO2 using the mol of O
convert mol to g again
Answer: Fur stuffed with feathers.
Explanation:
Ball games were popular throughout ancient history but also in the Middle Ages. Many of these games are the forerunners of today's American football and soccer. There are data on almost all continents on how peoples practiced some ball sports in antiquity. The game balls' look was not like today, it was mostly egg-shaped, and the materials for making it were different. The most common material for making the ball was leather, which was filled with feathers.
The answer is D since to calculate acceleration is used the formula a = delta v over delta t where delta v is the final velocity 11m/s less initial velocity 0m/s so delta v is 11m/s and delta t is final velocity 10s less initial velocity that always will be 0 then 10 - 0 = 10 so a = 11 over 10 that is 1.1m/s^2 (remember that is squared)
