Answer:
E. The gas absorbs 50 of energy as heat and does 50」ot work
Explanation:
This is following the law of thermodynamics that energy is neither created nor destroyed
The prefix your looking for is centi as in centimeter. I got this answer on google.
So please mark me as Brainiest.
Answer:
.04 kg m/s
Explanation:
Momentum is simply mass multiplied by velocity given by p = mv. You can consider momentum as mass in motion.
Before the collision, the data given for the toy train:
v = 0.5m/s
m = 75g
We need to convert grams into the SI unit of mass, kg.
75g / 1000g * 1kg = 0.075kg
Using p = mv, we can determine:
p = 0.075kg * 0.5m/s = 0.0375 kg m/s
Rounding to the value of 1 sig-fig, it comes out to be 0.04 kg m/s.
The <em>approximate</em> difference in pressure between the two balls is 1961.4 pascals.
<h2>Procedure - Pressure difference between two balls at distinct heights and submerged in the same fluid</h2>
<h3>Mathematical model for difference in pressure</h3>
The difference in pressure between the two balls is expressed by a formula derived from the concept of manometric pressure (), in pascals:
(1)
Where:
- - Height difference between balls 2 and 3, in meters.
- - Water density, in kilograms per cubic meter.
- - Gravitational acceleration, in meters per square second.
<h3>Calculation of the difference in pressure</h3>
If we know that , and , then the difference in pressure is:
The <em>approximate</em> difference in pressure between the two balls is 1961.4 pascals.
