__________ helps us adapt to our environment. It also generally __________ with age. A. Plasticity . . . decreases B. Developmen
Nana76 [90]
Not sure this is a physics question (probably biology).
Anyway, the correct answer is A):
"Plasticity helps us to adapt to our environment. It also generally decreases with age".
Plasticity is the ability to adapt to the environment. Since this ability is linked with brain functions, and brain functions worsen with age, then plasticity decreases with age.

1. A child sitting 1.2 m from the center of a merry-go-round moves with a speed of 1.1 m/s.
Ne4ueva [31]

Answers:

A) 1m/s^{2}

B) 22. 5 N

Explanation:

A) Since this situation is related to uniform circular motion, the centripetal acceleration a_{C} of the child is calculated by:

a_{C}=\frac{V^{2}}{r}

Where:

V=1.1 m/s is the speed

r=1.2 m is the child's distane to the center (the radius)

Hence:

a_{C}=\frac{(1.1 m/s)^{2}}{1.2 m}

a_{C}=1.008 m/s^{2} \approx 1 m/s^{2}

B) Knowing th centripetal acceleration and the mass m=22. 5 kg of the child, we can calculate the net horizontal force F by:

F=m a_{C}

F=(22. 5 kg)(1 m/s^{2})

F=22. 5 N

I need help find how much tension is in the string????
Nikitich [7]

Answer:

When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.

Image result for I need help find how much tension is in the string???? And can you explain how you got it after you get the answer plz????

Hence, in such a case the tension will be equal to the centrifugal force.

Formula for tension = centrifugal force = mv2/r.

So the formula of tension will be = centripetal force – force of gravity = mv2/r – mg = m(v2/r-g)

The formula of tension will be = centripetal force + force of gravity = mv2/r + mg = m(v2/r+g)

In one cycle, a freezer uses 585 J of electrical energy in order to remove 1750 J of heat from its freezer compartment at 10.0 F
gtnhenbr [62]

Answer:

(a) 0.525

(b) 1750J

Explanation:

Coefficient of Performance (COP) = Q2/(Q1 - Q2)

Q1 = heat rejected to the surrounding = 1750J

Q2 = heat absorbed in the environment = 585K

COP = 585/(1700 - 585) = 585/1115 = 0.525

(b). Heat expelled to the surrounding (room) = 1750J
