Answer:
total volume is 0.9125 m³
Explanation:
given data
oil = 28 litres
pressure p = 40 MPa
final pressure p2 = 35 MPa
initial pressure p1 = 30 MPa
y = 1,4
to find out
volume of accumulator
solution
so we here say that volume of oil
v3 - v2 = 28 litres
so v3 = 0.028 + v2 ......................a
and volume formula is
v1 = v2 ...................1
so v2 = v3 ..............2
put here value in equation 2
v2 = (0.028 + v2)
v2 = 0.274 m³
and here v1 will be
v1 = 0.274
v1 = 0.3365 m³
and v3 will be
v3 = 0.028 + v2
v3 = 0.028 + 0.274
v3 = 0.302 m³
so
total volume is v1 + v2 + v3
total volume = 0.274 + 0.3365 + 0.302
total volume is 0.9125 m³
Answer: 760 N
Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.
When Lucy stands on the weighing scale, net force due to gravity is
Hence, weight of Lucy is 760 N
In short: Electromagnetic radiation is energy that is propagated in the form of electromagnetic waves
Best example of electromagnetic radiation is sunlight. Vsible light of sunlight is only a small portion of the EM spectrum. EM radiation is a form of energy that takes many forms, f.e.: microwaves, radiowaves, etc.
The question is incomplete! The complete question along with answer and explanation is provided below.
Question:
A student bikes to school by traveling first 1.00 miles north, then 0.500 miles west and finally 0.200 miles south.
If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover
Given Information:
distance towards north = dn = 1.00 mi
distance towards west = dw = 0.500 mi
distance towards south = ds = 0.200 mi
Required Information:
distance covered by bird = db = ?
Answer:
distance covered by bird = 0.94 miles
Explanation:
As you can see in the attached image, by applying the Pythagoras theorem,
db = √(dn - ds)² + dw²
db = √ (1.0 - 0.20)² + 0.50²
db = √ 0.80² + 0.50²
db = 0.94 miles
Therefore, the bird would cover a distance of 0.94 miles
D, it depends. For water, the solubility increases as it get hotter, up to 100 degrees, but in some cases, liquids behave the opposite way.
