Answer:
7. 1ml = 20 drops
325ml = 6500
( 325 x 20 = 6500)
there are 6500 drops in a pepsi can
8. not sure sorry ; (
9. 1 mile per hour = 88 feet per minute
45 miles per hour = 3960 feet per minute
( 88 x 45 = 3960)
there are 3960 feet per minute in 45 miles per hour
Answer: 0.55 m/s
Explanation:
This situation is related to projectile motion (also called parabolic motion), where the main equations are as follows:
(1)
(2)
Where:
is the horizontal displacement of the pencil
is the pencil's initial velocity
since we are told the pencil rolls <u>horizontally</u> before falling
is the time since the pencil falls until it hits the ground
is the initial height of the pencil
is the final height of the pencil (when it finally hits the ground)
is the acceleration due gravity, always acting vertically downwards
Begining with (1):
(3)
(4)
Finding from (2):
(5)
(6)
Substituting (6) in (4):
(7)
Isolating :
(8)
(9)
Finally:
gas molecules having at least one oxygen atom
The animals which were delisted from the endangered species in July 2019 is Grey Wolf
Answer: Grey wolf
<u>Explanation:</u>
The ultimate goal of the Endangered Species Act was to preserve the species that are in the verge of extinction. The species are conserved and taken care of till they can be left free in the wild for it to survive of it's own.If the species has crossed all the recovery goals then they are delisted.
The grey wolf in July 2019 was delisted from the endangered species list. Now it is calculated that there are 6000 wolves that are found. But yet the grey wolf has not returned back to their livelihood and also to their sutable habitat.
Postitive ions have more protons than electrons, because protons are positively charged. Electrons have a negative charge, so if there were less protons than electrons the job would be negative. If there were the same amount of both, then the positive and negative charges balance each other out, making a neutral charge.
