Answer:
, level is rising.
Explanation:
Since liquid water is a incompresible fluid, density can be eliminated of the equation of Mass Conservation, which is simplified as follows:


By replacing all known variables:

The positive sign of the rate of change of the tank level indicates a rising behaviour.
Answer:
2084 kg*m/s
Explanation:
Impulse is change in momentum
Mathematically;
Impulse, J= F*t=mΔv where
F= ma = 1500 * { 30.56 - 16.67}/2*60
F= 1500 *0.11575
F= 174 N
J=F*t
J= 174*120*0.1
J= 2084 kg*m/s
Answer:

Explanation:
Given:
Dielectric of the medium between the plates (k) = 6.56
Area of eac plate (A) = 0.0830 m²
Separation between the plates (d) = 1.95 mm = 0.00195 m [1 mm = 0.001 m]
Maximum electric field
= 202 kN/C = 202000 N/C [1 kN = 1000 N]
Permittivity of space (ε₀) = 8.854 × 10⁻¹² F/m
The maximum potential difference across the plates of the capacitor is given as:

Now, capacitance of the capacitor is given as:

The maximum energy stored in the capacitor is given as:

Therefore, the maximum energy that can be stored in the capacitor is 
Answer:
protons+neutrons= mass number, so if the mass number is 13 and protons are 6 its 13-6=7 neutrons
Explanation:
mass number: the sum of the number of protons and
neutrons in an atom
this is key as it explains that protons+neutrons= mass number, so if the mass number is 13 and protons are 6 its 13-6=7 neutrons
The answer IS D!!!!!!!!!!!!!!!!!!!!!!!!!!!!
