The arrow in chemical equation means 'turns into' i think
Answer:
13.524 N
Explanation:
Volume and densities are given as:
ρ1 = 2.6 g/cm³ => 2600 kg/m³ ; V1 = 0.50 L => 0.5 x 10^-3 m³
ρ2 = 1.0 g/cm³ => 1000 kg/m³ ; V2= 0.25 L => 0.25 x 10^-3 m³
ρ3 = 0.7 g/cm³ => 700 kg/m³ ; V3 = 0.4 L => 0.4 x 10^-3 m³
Next is to calculate force exerted on the bottom of the container due to these liquids:
F= ρ1V1g + ρ2 V2 g+ ρ 3 V3g
where ,
ρ= density
V= volume
g= 9.8m/s²
F= g( 2600 x 0.5 x 10^-3 + 1000 x 0.25 x 10^-3 + 700 x 0.4 x 10^-3)
F= 9.8 (1.38)
F= 13.524 N
Therefore, the force on the bottom of the container due to these liquids is 13.524 N
According to the right hand grip rule; if you point your right thumb in the direction of the current flow and curl your fingers around the current carrying conductor, the fingers will point in the direction of the circular magnetic field around the conductor. Therefore,if the the current carrying carrying conductor is held with the current flowing towards you, using right hand grip rule the lines of magnetic field will act towards a counterclockwise direction or anticlockwise direction.
Answer:
σ =4.180×10^{-9} C/m^2
Explanation:
electric field due to non conducting sheet is

the force acting on the piece of Styrofoam
Eq= mg
⇒E= mg/q
now,

⇒

charge per unit area (in C/m2) on the plastic sheet σ =4.180×10^{-9} C/m^2
Answer:

Explanation:
We know that speed is defined as distance moved per unit time hence expressed as
where v is speed in m/s, d is distance in m and t is time in seconds. Making d the subject of the above formula then

Substituting 343 m/s for d and 10 s for t then

Therefore, the distance between speaker and deter is
