<h2>The flux through each face is q/6ε₀ .</h2>
Explanation:
The charge q is placed at the center of the cube of side L
According to Gauss's law the flux through any closed surface is q/ε₀
here q is the charge enclosed .
In this case cube has the six faces . The flux through each face = q/6ε₀
In the second case The cube has the face with length L₁
The flux through each face = q/6ε₀
Thus flux through the cube does not depend upon the size of the cube .
Answer:
6.575
Explanation:
T1 = 30C = 30 + 273 = 303 K
T2 = - 10 C = - 10 + 273 = 263 K
The coefficient of performance of heat pump
k = T2 / (T1 - T2)
k = 263 / (303 - 263) = 6.575
Answer:
1. Periods; that are what horizontal rows on a periodic table are called.
2. Each period represents the number of levels
Explanation:
The total force on the ground due to the bricks is 47,040 N.
<h3>
Total force on the ground</h3>
The total force on the ground due to weight of the bricks is calculated as follows;
Fₙ = mg
where;
- Fₙ is normal force
- m is mass of the brickes
- g is acceleration due to gravity
Fₙ = (1500 x 3.2) x 9.8
Fₙ = 47,040 N
Thus, the total force on the ground due to the bricks is 47,040 N.

Answer:
a=1.03 m/s²
Explanation:
given required
dist=22.1 cm a=?
m1=2.1 kg
m2=1.56 kg
m3=1.93 kg
g=9.8 m/s²
solution
there are three forces on this system so we can solve by using newton's second law as follows
t1,t2,and weight of are the only forces acted on the system,
if we take the system on the left mass m3
-m3a=t2-m3g
-1.93 kg×a=t2-1.93 kg×9.8 m/s²
-1.93 kg×a=t2-18.91 N................................ eq 1
take at the right mass m2
m2a=t2-m2×g
1.56 kg×a=t2-1.56 kg×9.8 m/s²
1.56 kg×a=t2-15.288 N...................................2
add the two equations simultaneously and then solve for a,
-1×(-1.93 kg×a=t2-18.91 N) multiply by -1 the first and add the two equations
1.56 kg×a=t2-15.288 N
3.49 kg×a=3.622 N
a=1.03 m/s²
