An object will remain at rest of maintain constant straight-line motion unless acted on by a force that is c. unbalanced
Answer:
Explanation:
Ball rises and falls in equal periods. Because it goes by same speeds and same route. Therefore t_{rise} = t_{fall} =2.5 s
In free fall and vertical throw movement: x= (1/2).a.t^{2}
Here, we can find the height of the ball
x= (1/2).5.(2.5^{2}) = 15.625 m
From the attaches V-t graphics, x=V.t/2
15.624=V.(2.5)/2
V=12.5 m/s
An electron that is far away from the nucleus have higher energy than an electron near the nucleus. Nucleus are positively charged and those electrons near it get attracted; those electrons gain kinetic energy hence reducing their internal energy. The electrons far from nucleus have low kinetic energy hence more internal energy.
Answer: 200 joules I think.

Answer:
Polymers
Explanation:
- Polymer substrates are the main components in this tissue engineering. Polymer substrates provide the essential factors for physiological regeneration process. Polymer scaffolds are combination of polymers with, drugs, cells, can be used for therapeutic treatment of diseases and also for regeneration of several vital organs of human body such as ear, blood vessels, coronary artery etc.
- Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
