D = 110 m,  t = 5 s
v o = 110 cs : 5 m = 22 m/s
-------------------------------------
v = v o - a t
v = 0 m/s,  v o =  22 m/s,  t = 4 s
0 = 22 - 4 a
4 a = 22
a = 22 : 4
a = 5.5 m/s²
g = 9.80 m/s²
9.80 : 5.5 = 0.56 
Answer:
The magnitude of its acceleration is 5.5 m/s or 0.56 g.

In this schematic, the total resistance is 50 ohms. 100 ohms. 1,000 ohms. 100 ohms 10,000 ohms
Mrrafil [7]

The total resistance of the given circuit is if the circuit contains 100ohms,1000 ohms,100 ohms and 10,000 ohms resistors.

Resistance is measured in ohms, and it is represented by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who concentrated on the connection between voltage, current and resistance. He is credited for planning Ohm's Regulation.

Resistance estimations are regularly taken to demonstrate the state of a part or a circuit.

  • The higher the resistance, the lower the ongoing current. On the off chance that strangely high, one potential reason (among many) could be harmed guides because of consuming or erosion.
  • The lower the obstruction, the higher the ongoing stream. Potential causes: protectors harmed by dampness or overheating.

Since resistors are connected in series, so we know that when resistors are connected in series, total resistance is given by the formula

Rₙ=R₁+R₂+R₃+---------------Rₙ

So, resistors value are 50 ohms. 100 ohms. 1,000 ohms. 100 ohms 10,000 ohms.

Therefore, total resistance is 50+100+1000+100+10000=10250ohm

Hence, total resistance is 10250ohm

If the depth of water in a well is 10m, what is the pressure exerted by it the bottom of the well ? ( Use g = 10 m/s2)
Tasya [4]

Answer:

The precise answer depends on the density and therefore the temperature of the water, but we can obtain a reasonable approximation by assuming that the density of the water is 1000 kilograms per cubic meter (kg/m³).

Since the depth of the water in the well is 10 m, the volume of water directly above an area A of a square meters (m²) at the bottom of the well is 10×a m³.

Since the density of the water is 1,000 kg/m³, the mass of water directly above area A is (1,000 kg/m³) × (10×a m³) = (1000×10×a kg) = 10,000×a kg.

Since g = 9.8 m/s², the force of gravity acting on the water directly above area A is (9.8 m/s²) × (10,000×a kg) = 9.8×10,000×a N (newtons) = 98,000×a N.

So the pressure of water acting on area A is (98,000×a N)/(a m²) = (98,000×a)/a N/m² = 98,000 pascals (pa). And since A could be any given area at the bottom of the well, this is the pressure at any point at the bottom of the well.

So the pressure at the bottom of the well is 98,000 pascals (or 98,000/101,325 standard atmospheres = 560/579 atmospheres ~ 0.967 standard atmospheres).
