Charge = (current) x (time)
Charge = (0.4 Ampere) x (2 seconds)
Charge = (0.4 Coulomb/second) x (2 seconds)
<em>Charge = 0.8 Coulombs</em>
Answer:
Weight = 3.924 N
Bouyant force = 2.5N
Apperent weight= 1.424N
Explanation:
Radius of the sphere = 0.0165 m
Volume of sphere = (4πr³)/3
Volume = 4.189*(4.49*10^-6)
Volume = 1.88*10^-5
For the weight.
Mass = density* volume
Mass = 2.14*10^4 *(1.88*10^5)
Mass = 0.4 kg.
Weight = mass * acceleration due to gravity
Weight = 0.4*9.81
Weight = 3.924 N
For the buoyant force Fb
Fb = volume * density of fluid* acceleration
Fb = (1.88*10^5)*1.36 × 10^ 4*9.81
Fb = 2.5N
For Apperent weight
True weight - buoyant force = Apperent weight.
3.924- 2.5N= 1.424N
I believe the answer might be macro, as unemployment is a macro issue and macroeconomics looks at the economy as a whole.
