The answer to your question is: Yes.
To solve each and every one, write the two given numbers in place of their letters in the given equation, and then solve the equation for the letter that's left.
For example, let's do #1 together. I'll do all the work, and you just watch.
#1 says that s=d/t. It also tells us that 'd' is 4 and 't' is 2. So here's a great idea: Why don't we write '4' where it says 'd', and write '2' where it says 't', and then see what we've got ?
s = 4/2
Wow ! We know that 4/2 is 2 . So s=2 and that's exactly the answer to the question !
Now it's YOUR turn. Do the next 25 problems the same way.
Potential Energy
Potential energy is the energy an object has because of its position to move. Gravitational potential energy can be calculated by multiplying the mass of an object, the gravitational pull, and the height of the object together. In our project the weights, cups, marbles and dominos all have a potential energy as well as other objects.
Kinetic Energy
Kinetic energy is energy due to motion. To calculate this, use the equation KE=0.5mv^2. The work, potential energy, and kinetic energy of an object will always be equal to eat other. Kinetic energy can be calculated by any objects in motion on the machine, such as the marbles, car, and the dominos.
SRY I HAVE ONLY THIS MUCH OF INFORMATION ABOUT THIS............I ONLY HOPE THAT THIS WILL HELP YOU MATE.......
Answer:
s₁ = 4.67 m from car A
Explanation:
Since, the cars are moving at a constant speed. Hence, we will apply the equation for uniform motion here:
s = vt
where,
s = distance covered
v = velocity
t = time taken
For Car A:
s₁ = (1.4 m/s)t
For Car B:
s₂ = (2.2 m/s)t
Because the time will be same at the collision. At collision the distance covered by Car A and Car B must be 12 m altogether. Hence:
s₁ + s₂ = 12 m
using values:
(1.4 m/s)t + (2.2 m/s)t = 12 m
t = 12 m/3.6 m/s
t = 3.333 s
Substitute this in the equation of s₁:
s₁ = (1.4 m/s)(3.33 s)
<u>s₁ = 4.67 m from car A</u>
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.
