Answer:
Hence the pressure is 
Explanation:
Given data
Q=1500 J system gains heat
ΔV=- 0.010 m^3 there is a decrease in volume
ΔU= 4500 J internal energy decrease
We know work done is
W= Q- ΔU
=1500-4500= -3000 J
The change in the volume at constant pressure is
ΔV= W/P
there fore P = W/ΔV= -3000/-0.01= 3×10^5
Hence the pressure is
5.6•10^5 so it’s to the power of positive 5
Answer:
Explanation:
<u>Tangent and Angular Velocities</u>
In the uniform circular motion, an object describes the same angles in the same times. If 
is the angle formed by the trajectory of the object in a time t, then its angular velocity is
if is expressed in radians and t in seconds the units of w is rad/s. If the circular motion is uniform, the object forms an angle 
in 2t, or 
in 3t, etc. Thus the angular velocity is constant.
The magnitude of the tangent or linear velocity is computed as the ratio between the arc length and the time taken to travel that distance:
Replacing the formula for w, we have
Festival dances can help improve your fitness because your moving and exercising your body without even knowing for hours therefore it helps with weight loss and your health in general.
Answer:
The center of the Milky Way most likely contains a supermassive black hole.
Explanation:
Because it is an eleptical galaxy, it has a little rotation to it but not enough to flatten out so the center will contain a supermassive black hole.
