Answer:
Although the vast majority of DNA in most eukaryotes is found in the nucleus, some DNA is present within the mitochondria of animals, plants, and fungi and within the chloroplasts of plants.
Explanation:
Answer:
k = 100 N/m
Explanation:
The elastic potential energy of a spring is equal to (1/2)kx^2, where k is the spring constant and x is the distance compressed. If the elastic PE is equal to 2J, we can solve for k. Make sure to convert units from cm to m:
(1/2)kx^2 = 2J
kx^2 = 1
k = 1/x^2
k = 1/(0.1)^2
k = 100 N/m
Answer:
1.75 s
11.4 m
Explanation:
In the y direction:
Given:
Δy = -15.0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-15.0 m = (0 m/s) t + ½ (-9.8 m/s²) t²
t = 1.75 s
In the x direction:
Given:
t = 1.75 s
v₀ = 6.50 m/s
a = 0 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (6.50 m/s) (1.75 s) + ½ (0 m/s²) (1.75 s)²
Δx = 11.4 m
