Answer:22.22m/s
Explanation:
Answer: 22.22 m/s
Explanation:
Using the law of conservation of momentum:
Initial momentum of the system = final momentum of the system.
mu+m'u' = mv+m'v'
where u and u' are the initial velocities.
v and v' are the final velocities.
mass of bullet, m = 0.04 kg
mass of the block of wood, m' = 0.5 kg
initial velocity of bullet, u = 300 m/s
initial velocity of block, u' = 0
after collision, block and bullet would move together with velocity v
⇒0.04 kg × 300 m/s + 0 = 0.54 kg × v
⇒ v = 22.22 m/s
Thus, the bullet and the wood block move together as one object with the speed 22.2 m/s.
The answer is:
A) sandards of the profession
The explanation:
-peer review is an important part of this process. Peer review is an important part of the quality control mechanism that is used to determine what is published, and what is not.
- In the medical community, most scholarly work or research will not be seriously considered until it has been validated by peer review.
- the peer review process acts as a filter for interest and relevance to the field being targeted by a journal.
Answer:
63.5 °C
Explanation:
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
Also,
Considering the ideal gas equation as:-
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 8.314 J/ K mol
So,
Also, for change in volume at constant pressure, the above equation can be written as;-
So, putting in the expression of the work done, we get that:-
Given, initial temperature = 28.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28.0 + 273.15) K = 301.15 K
W=1770 J
n = 6 moles
So,
Thus,
The temperature in Celsius = 336.63-273.15 °C = 63.5 °C
<u>The final temperature is:- 63.5 °C</u>
