Answer:
The submerged effective density is 86.93 kN/m³ or 8.693 Mg/m³
Explanation:
Given;
wet density of soil sample = 2.5 Mg/m³ = 25 kN/m³
Specific gravity of solid particle = 2.7
The dry unit weight of soil;
for undisturbed state, the volume of the soil is;
Submerged effective density is given as;
density of water (ρw) = 2.7 x 25 kN/m³ = 67.5 kN/m³, substitute this in the above equation;
Therefore, the submerged effective density is 86.93 kN/m³ or 8.693 Mg/m³

What is capacitor?</h3>
In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.
Capacitance refers to a capacitor's effect. While there is some capacitance between any two nearby electrical wires in a circuit, a capacitor is a component made to increase capacitance. The term "condenser" or "condensator" originally applied to the capacitor. Condenser microphones, sometimes known as capacitor microphones, are a remarkable exception to the general lack of usage of this name and its cognates in English.
Practical capacitors come in a wide variety of physical shapes and constructions, and there are numerous varieties that are used often.

Answer:
The average force exerted by the person on the box is 20 N.
Explanation:
Given that,
Impulse applied to the box, m = 5 kg-m/s
Time of contact of the person with the box is 0.25 seconds. We need to find the average force exerted by the person on the box. The impulse applied on an object is given by :
F is the average force exerted by the person on the box
F = 20 N
So, the average force exerted by the person on the box is 20 N. Hence, this is the required solution.
