What does the delta symbol represent in the equation?

Physics

Alex_Xolod [135]3 years ago
6 0

Answer:

Whenever you see the delta symbol infront of another, it always represents change. In other words:

Δu = u_f - u_i

  • u_i means "initial velocity"
  • u_f means "final velocity"

And in general, ΔX means Xfinal - Xinitial

An ideal gas is at a pressure 1.00 Ã 105 n/m2 and occupies a volume 2.00 m3. if the gas is compressed to a volume 1.00 m3 while
blsea [12.9K]
The behavior of an ideal gas at constant temperature obeys Boyle's Law of
p*V = constant
where
p = pressure
V = volume.

Given:
State 1:  
  p₁ = 10⁵ N/m² (Pa)
  V₁ = 2 m³
State 2:
  V₂ = 1 m³

Therefore the pressure at state 2 is given by
p₂V₂ = p₁V₁
or
p₂ = (V₁/V₂) p₁
    = 2 x 10⁵ Pa

Answer: 2 x 10⁵ N/m² or 2 atm.

A spacecraft and a staellite are at diametrically opposite position in the same circular orbit of altitude 500 km above the eart
Tanya [424]

Answer:

Hello the diagram related to your question is attached below

answer: a) 851 m/s

             b)  8506.1 secs

Explanation:

calculate the periodic time of the satellite using the equation below

t = \frac{2\pi }{R} \sqrt{\frac{(R+h)^{3} }{g} }  --  ( 1 )

where ; R = 6370 km

h = 500 km

g = 9.81 m/s^2

input given values into equation 1

t = 5670.75 secs

next calculate the periodic time taken by the space craft  

<u>a) determine the increase in speed </u>

V = v - \sqrt{\frac{gR^2}{R + h} }  

where ; v = 8463 m/s , R = 6370 km, h = 500 km

V = 851 m/s

b) Determine the periodic time for the elliptic orbit

τ = \frac{3t}{2}

 = \frac{3*5670.76}{2}  =  8506.1 secs

attached below is the remaining part of the detailed solution

True or False: As the mass of an object increases, the gravitational pull increases
Lunna [17]

Answer: The answer is obviously True!!!!

Explanation: The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects. ... However, the exponent on the mass terms is one.

A system gains 3220 J of heat at a constant pressure of 1.32 × 105 Pa, and its internal energy increases by 3990 J. What is the
alukav5142 [94]

Answer:

ΔV= -5.833×10⁻³

Negative sign indicates that volume decreases

Explanation:

Given data

System heat gains Q=3220 J

Pressure P=1.32×10⁵Pa

Internal energy increases ΔU=3990 J

To find

Change in volume ΔV

Solution

First we need to find the work done

So

W=Q-ΔU

W=3220J-3990J

W= -770J

Now for the change in volume at constant pressure

ΔV=(W/P)

=(\frac{-770J}{1.32*10^{5}Pa } )\\= -5.833*10^{-3}

ΔV= -5.833×10⁻³

Negative sign indicates that volume decreases
