Explanation:
It is given that,
Initial temperature,
Pressure,
Compression ratio,
Let T₂ is the final temperature of air. Using the relation for reversible adiabatic process as :
............(1)
Where,
For air, and
So, equation (1) becomes :
So, the final temperature of air is 719.49 K. Hence, this is the required solution.
Answer: either 3.20s or 1.18s
Explanation:
Answer:
Explained
Explanation:
The minimum energy required by a photon to create a electron-positron pair must be equal to the sum of rest mass energies of both electron and positron.
therefore E= 2m_ec^2
=2×0.511 MeV
=1.02 MeV
Below this , the process would not occur. So, in the energy range of > 1.02 MeV
The most dominant process will be in pair production.
At the range of 200 KeV to 3 MeV, The most dominant Process is compton Scattering.
below 200 KeV , Photo electric effect is more dominant.
Answer:
The answer is 8.44*10^9 Newton
Explanation:
The equation for universal gravitation is:
Where:
G= 6.674×10^−11 N · (m/kg)^2
M(earth)=5.972 × 10^24 kg
M(asteroid)=5.0×10^13 kg
r=1.537*10^9 m (Calculated from average distance between moon and earth)
The force will be:
8.44*10^9 Newton
The time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.
<h3>What is force?</h3>
The force is the action of push or pull to move or stop an object.
Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.
Force is related to power by the relation
Force = Power / Velocity
Put the values, we get
8 = 3/V
V = 0.375 m/s
Velocity is defined as the ratio of distance and the time taken.
The box is moved by the distance of 9.72 meters. So, time taken is
V = d/t
0.375 = 9.72/t
t =25.9 seconds.
Thus, time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds.
