I think it is number four because he is sitting on the chair and exerting force on the chair because the chair is not pushing him
Answer: 62.86 coulombs
Explanation:
Resistance (R) = 210Ω
Voltage of battery (V) = 110V
total amount of charge (Q) = ?
Time (T) = 2 minutes
The SI unit of time is seconds so convert 2 minutes to seconds
(If 1 minute = 60 seconds
2 minutes = 2 x 60 = 120 seconds)
To get the total charge, first get the current (I) flowing in the circuit by applying the formula V = IR
110V = I x 210Ω
I = 110V/210Ω
I = 0.524 Amps
Then, apply the formula
Charge = current x time
i.e Q = IT
Q = 0.524 Amps x 120 seconds
Q = 62.86 coulombs
Thus, 62.86 coulombs of charge passes through the circuit.
Answer:
6.67×10⁻⁸ cm³/g/s²
Explanation:
6.67×10⁻¹¹ Nm²/kg²
= 6.67×10⁻¹¹ (kg m/s²) m²/kg²
= 6.67×10⁻¹¹ m³/kg/s²
= 6.67×10⁻¹¹ m³/kg/s² × (100 cm/m)³ × (1 kg / 1000 g)
= 6.67×10⁻⁸ cm³/g/s²
To identify which one is ionic compound, you would select the compound with the high melting point. Ionic compounds<span> have high </span>melting points<span> because the electrostatic interactions that hold the compounds together are very strong. Hope this answers the question.</span>
