Answer:
14 m/s²
Explanation:
Start with Newton's 2nd law: Fnet=ma, with F being force, m being mass, and a being acceleration. The applied forces on the left and right side of the block are equivalent, so they cancel out and are negligible. That way, you only have to worry about the y direction. Don't forget the force that gravity has the object. It appears to me that the object is falling, so there would be an additional force from going down from weight of the object. Weight is gravity (can be rounded to 10) x mass. Substitute 4N+weight in for Fnet and 1kg in for m.
(4N + 10 x 1kg)=(1kg)a
14/1=14, so the acceleration is 14 m/s²
Answer:
The correct option is A = adiant negy.
Plant material in the soil called organic carbon can't decompose, or rot away.

Basically you are using d = r * t
Frequency is 1 / t
d is more commonly represented by lambda (
). Lambda is the wavelength.
so the formula = c / f
More commonly it is written as *f = c.
Givens
c = 3*10^8 m/s
= 0.1 nm = 0.1 nm *[1 m /1 * 10^9 nm] = 0.1 * 10^ - 9 meters.
f = ??
f = 
f = 3 * 10^8 * 10^9 / 0.1 = 3 * 10^18
Answer: C
Ten
= c/f
= 3*10^8 / 1 * 10^16
= 3*10^-8 meters
= 30 * 10^-9 meters = 30 nm
Answer: D
