True or False: Primary and secondary succession both end with the formation of a climax community.

jolli1 [7]

Answer: true

Explanation: Ecological succession, the process by which the structure of a biological community evolves over time. Two different types of succession primary and secondary have been distinguished The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

Answer: 95.7 N

Explanation: The tension on the chandelier is equal to the its weight.

Weight is the force directed downwards and tension is the force exerted of the opposite side.

T = W of the chain + W of the chandelier

= m1( g) + m2 (g)

= 0.37 kg ( 9.8 m/s2) + 9.4 kg (9.8 m/s2)

= - 95.7 N it means the force is directed downwards

since tension is equal weight

T = 95.7 N

A 5.50-kg object is hung from the bottom end of a vertical spring fastened to an overhead beam. The object is set into vertical

iris [78.8K]

Answer:

17.71N/m

Explanation:

The period of the spring is expressed according to the expression;

$T = 2 \pi \sqrt{\frac{m}{k} } \\$

m is the mass of the object

k is the force constant

Given

m = 5.50kg

T = 3.50s

Substitute into the formula;

$T = 2 \pi \sqrt{\frac{m}{k} } \\3.5 = 2 (3.14) \sqrt{\frac{5.5}{k} } \\3.5 = 6.28 \sqrt{\frac{5.5}{k} } \\\frac{3.5}{6.28} = \sqrt{\frac{5.5}{k} } \\0.557 = \sqrt{\frac{5.5}{k} } \\square \ both \ sides\\0.557^2 = (\sqrt{\frac{5.5}{k} })^2 \\0.3106 = \frac{5,5}{k}\\k = \frac{5.5}{0.3106}\\k = 17.71N/m$

Hence the force constant of the spring is 17.71N/m
