Answer:
A) 7×10⁻⁸ N
Explanation:
r = Distance between the two skaters = 2 m
m₁ = m₂ = Mass of the two skaters = 65 kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
From Newton's Law of Universal gravity

∴ Force of gravity between the two skaters is 7×10⁻⁸ N

Answer:
Total Resistance in circuit is Fourteen Ohms <u>(14 Ω).</u>
<u></u>
Explanation:
How do we know, if the resistors are connected in series, the total resistance is the <u>sum of all the resistors.</u>
(Important: The total resistance can only be added just when the resistors are <u>connected in series</u>)
Then, total resistance (<em>TR </em>) is the sum of all resistors (<em>T1 + T2</em>, in this case)
TR = T1 + T2
According to problem data, we have:
TR = 8 Ω + 6 Ω
TR = 14 Ω

Answer:

Explanation:
As we know that tank itself has mass given as 13.4 kg
so it is given as

also the tank contains air in it and the mass of air inside the tank is also given as 4.47 kg
so it is

so total mass of the tank is the mass of the empty tank and mass of air in the tank
