Part B
1. The symbol (from a similar question) suggest the steps used to conserve resources
2. i) Reduce
ii) Reuse
iii) Recycle
Explanation:
1. The symbol suggests that in order to maintain sustainable use of our natural resources we can conserve them reducing waste, making use of reusable products, and recycling items to produce new items
2. i) The conservation step to be done first in the 3R's is Reduce
The natural resources can be conserved by reducing the amount of waste produced and also reducing the usage of non renewable natural resourced
ii) The next conservation step is to follow after it is no longer possible to reduce wastage is Reuse
There are several items that can be made use of for other purpose after they have been used including, water, bags for shopping, reusable nose masks
iii) The item which should be done last is Recycle
To recycle is to process used materials to create other items which can then be used as new items
Examples include;
Iron, Plastics, glass, paper, tires, and electronics
Answer:
Todo ser humano, al nacer, es un organismo inacabado en términos tanto físicos como psicoemocionales. Es decir, el humano, al nacer, lo hace sin la posibilidad de autosustentarse en el futuro inmediato: no puede caminar, expresarse, tener pensamiento analítico ni la capacidad de resolver las problemáticas que les afectan.
Ello hace que el humano requiera para su desarrollo de un acompañamiento absoluto por parte de su madre en el período inicial de su vida, tanto para alimentarlo como para transmitirle las nociones básicas de supervivencia; y posteriormente requiera de un entorno social idóneo que le permita desarrollarse emocionalmente para poder vivir normalmente en sociedad.
Además, respecto de sus características físicas, necesita también aprender a caminar, movilizarse y demás atributos físicos que le garanticen un normal desarrollo motor, con lo cual es fundamental que dicha enseñanza provenga también del entorno que lo rodea.
As per the kinematics equation
when glove comes back to his hand the displacement will become zero
Part b)
Now as per symmetric nature the time to reach the top will be same as the time to come back again
so here we can say
so it took 0.61 s to reach the top
Answer:
P=1.53 i +1.92 j kg.m/s
P=2.45 kg.m/s
α = 51.34
Explanation:
Given that
m=123 g = 0.123 Kg
U= 25 m/s
θ=30°
t= 0.6 s
This is the case of projectile motion
So the horizontal component of velocity U = u cosθ
u = 25 cosθ
u = 25 cos 30°
u=21.65 m/s
The vertical component of velocity U = U sinθ
Vo= U sinθ
Vo= 25 sin 30°
Vo = 12.5 m/s
We know that horizontal component of velocity of ball will remain same.So the horizontal component of momentum
Px= m u
Px= 0.143 x 12.5 kg.m/s
Px=1.53 kg.m/s
The vertical component of ball after 0.6 s
V= Vo- g t
V= 21.65 - 10 x 0.6 m/s
V= 15.65 m/s
Py= m V
Py= 0.123 x 15.65 kg.m/s
Py=1.92 kg.m/s
P=1.53 i +1.92 j kg.m/s
Magnitude P
P=2.45 kg.m/s
Direction
α = 51.34° (measured from x direction)
Answer: 1) c. The energy on the macroscopic scale decreased, and the energy on the molecular scale increased.
2) d. Friction converts some energy on the macroscopic scale to energy on the molecular scale.
3) d. The mechanical energy of the system decreased because of friction.
4) d. The mechanical energy of the system at the beginning of the experiment is equal to the mechanical energy of the system at the end of the experiment.
5) d. The mechanical energy of the system decreased due to the transfer of energy on a macroscopic scale to energy on a molecular scale.
