Answer:
16.00L
Explanation:
First you calculate the number of moles in the system:

To find the new volume of the system you use the following formula for an isobaric procedure:

hence, the new volume is 16.00L
Answer:
a. A = 0.0859 m^2
b. A = 0.0178 m^2
Explanation:
Two flat surfaces are exposed to a uniform, horizontal magnetic field of magnitude 0.47 T. When viewed edge-on, the first surface is tilted at an angle of from the horizontal, and a net magnetic flux of 8.4 103 Wb passes through it. The same net magnetic flux passes through the second surface. (a) Determine the area of the first surface. (b) Find the smallest possible value for the area of the second surface.
take note that the question has not specified th angle which the surface is tilted so i assume the angle is at
to the horizontal
flux = BAcos(
)
B=magnetic flux in Weber
A=area of the flat surface in m^2
=the angle to the horizontal
a) 8.4 x10^-3= (.47)Acos(78)
alpha has to be the angle from the normal and not the horizontal so 90-12=78,
8.4 x10^-3
/(.47)cos(78)
A = 0.0859 m^2
b) If flux remains the same then for it to be the smallest possible area it needs to be perpendicular to the magnetic field so alpha would be 0.
8.4 x10^-3 = (.47)Acos(0)
A = 0.0178 m^2
Answer: 294 N
Explanation:
Since the Normal Force
is equal to the weight
of the dog, we have:

Where:
is the mass of the dog
is the acceleration due to gravity on the Earth's surface
Solving:


Answer:
v0 = 24.42 m/s (Approx)
Explanation:
Given:
Increase in frequency = 7.1% =
Computation:
Assume n = 100%
n1 = [(v+v0)/(v+v1)]n
[100 + 7.1] = [(344+v0)/(344+0)]100
107.1 = [(344+v0)/(344)]100
v0 = 24.42 m/s (Approx)
