EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEee
I’ll say c Bc it make more since to find the travel distance
Answer:
10392.30N
Explanation:
We proceed by computing the individual force exerted by the boats
For the first boat
The angle is 30 degree to the vertical
Hence
Force = F cos θ
F=6000 cos 30
F=6000*0.866
F=5196.15 N
Since the boats are two and also at the same angle and also exerting the same force
The Net force = 2*5196.15
Net force=10392.30N
Answer:
Explanation:
Change in gravitational energy of the ball = mgh
5 mutiply 10 multiply 1.7 = 85J
Potential energy at height = Kinetic energy at bottom
KE= 85J
Velocity
v=5.83m/s
Complete Question
The complete question is shown on the first and second uploaded image
Note : The resistance is R = 147 Ohms
Answer:
The current density in terms of resistivity is 
The current is
Explanation:
From the question we are told that
The length of the wire is 
The radius of the circular cross-sectional area is 
The electric field strength is E =9.41 V/m
Generally the current density is mathematically represented as

Here
is the resistivity of the wire which is mathematically represented as

So

Here A is the cross-sectional area which is mathematically represented as

So

Generally the current density can also be mathematically represented as

So
