Use the projectile motion equations
H = v^2 x sin^2(θ) ÷ 2g
t = 2 x v x sinθ ÷ g
R = v^2 x sin2θ ÷ g
Total Current = 2 Amps
Req total = 60 ohms
Current on EF mesh = 1/3 Amp
Current on 24 ohms resistor = 1/6 Amp
Voltage on the 40ohms resistor is lefting.
The density of the fluid is 776.3 
<u>Explanation:</u>
Buoyant force is the upward pushing force whenever an object is trying to get immersed in fluid. So this is the force given by the fluid on the object which is trying to get immersed. The buoyant force is found to be directly proportional to the product of density of the object, volume of the object. And here the acceleration due to gravity will be acting as proportionality constant.

As, buoyant force is given as 671 N and volume is 0.0882
and acceleration is known as 9.8 m/
. Then density is

Thus,

Density is 776.3 kg
.
The awnser would be True. Hope I helped!
C and d have the same amount of protons and electrons
