Answer:
It would be D. Proterozoic because they appeared 542 million years ago.
Answer:
The wavelenght is λ= 6 * 10⁻⁴m.
Explanation:
v= 1500 m/s
f= 2.5 MHz = 2.5 *10⁶ Hz
λ=v/f
λ= 6 * 10⁻⁴ meters
The correct answer is the Black Market.
The Black Market refers to the informal (and sometimes formal) system of trading of illegal goods by merchants and dealers of products such a weapons, drugs, and good that have been banned by countries. This can also apply to informal marketplaces in countries with sanctions placed upon them get goods that formal treaties are blocking the people from accessing.
Answer: 0.5m/s²
Explanation:
Given that,
acceleration of bike (a) = ?
Mass of bike (m) = 20kg bike
(Note that the displacement of the bike is in the northerly direction)
constant unbalanced force (f) = 10 N
According to Newton's second law of motion, the acceleration of the bike will be directly proportional to force acting on it but inversely proportional to the mass of the bike.
Hence, Force α mass x acceleration
f = ma
Make a the subject formula
a = f / m
Now find the acceleration of the bike
a = 10N / 20kg
a = 0.5m/s²
Thus, the acceleration of the bike pedaled in the northerly direction is 0.5m/s²
Answer:
Explanation:
Given data:
Rotating cylinder length = 9 mi
diameter of cylinder is 5.9 mi
we know that linear acceleration is given as
a = r ω^2
where ω is angular velocity
so
