If the height of the cannon and the ground are the same and in the absence of air resistance, the fact that it is moving horizontally changes nothing from a static problem in which a 45 degree angle gives maximum x-axis displacement.
Answer:
Five kingdoms & Seven levels
Explanation:
Robert H. Whittaker proposed five kingdom classical system for living organisms in 1969. These were: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Animalia, and Kingdom Plantae. His work was the improvement of earlier work conducted by Carl Linnaeus who proposed three kingdom classification system (Animalia, Plantae, and Protista).
Whittaker's system further categorized each kingdom to seven levels. These were: Kingdom → Phylum → Class → Order → Family → Genus → Species. This categorization was based on similarities in organisms at different levels.
PS: The scientific name of each organism is the combination of genus and family name.
358 rocks, critical thinking
Answer:
0,93 atm
Explanation:
For this we will use PV = nRT
P is what we want to find
V = 1 L
n = 
= 0,038 moles
R = 0,082 
T = 25°C = 298,15 K
P * 1 = 0,038 *0,082 * 298,15
P = 0,93 atm
