<u>Answer:</u>
area of point has more pressure.
<u>Explanation:</u>
formula's : pressure = force ÷ area
1st pressure,
200 ÷ 0.2 = 1000 Pa
2nd pressure,
200 ÷ 0.004 = 50000 Pa
<h3>Therefore the pressure on the area of the point is more.</h3>
Answer:
c=326.5177 J/kg.K
Specific heat is c=326.5177 J/kg.K
Explanation:
In order ti find the specific heat, we will proceed as follow:
Formula we are going to use is:

Where:
Q is the heat energy added
m is the mass of sample
c is the specific heat
is the temperature Rise.
First we will find the mass:
Weight=m*g (g is gravitational acceleration=9.8 m/s^2)

Rearranging above formula:


c=326.5177 J/kg.K
Specific heat is c=326.5177 J/kg.K
Answer: I think maybe thru Convection?
Explanation:
cause convection causes the heat to stay to the top and the cold air stay's to the bottom so maybe i would say Convection.... Is there any answer choices?
<u><em>The question doesn't provide enough data to be solved, but I'm assuming some magnitudes to help you to solve your own problem</em></u>
Answer:
<em>The maximum height is 0.10 meters</em>
Explanation:
<u>Energy Transformation</u>
It's referred to as the change of one energy from one form to another or others. If we compress a spring and then release it with an object being launched on top of it, all the spring (elastic) potential energy is transformed into kinetic and gravitational energies. When the object stops in the air, all the initial energy is now gravitational potential energy.
If a spring of constant K is compressed a distance x, its potential energy is

When the launched object (mass m) reaches its max height h, all that energy is now gravitational, which is computed as

We have then,


Solving for h

We have little data to work on the problem, so we'll assume some values to answer the question and help to solve the problem at hand
Let's say: x=0.2 m (given), K=100 N/m, m=2 kg
Computing the maximum height


The maximum height is 0.10 meters
