Answer;
the potential difference
The magnitude of the electric current is directly proportional to the potential difference of the electric field
Explanation;
An electric current results from the collective movement of free charges under the effect of an electric field. An electric field exists and can be observed in the space around a single charge or a number of charges.
Electric fields cause charges to move. It stands to reason that an electric field applied to some material will cause currents to flow in that material. In other words, the current density is directly proportional to the electric field. The constant of proportionality σ is called the material’s conductivity.
Answer:
The answer to your question is: a = 1.99 m/s²
Explanation:
Data
mass = 20 kg
angle = 56°
Force = 71 N
horizontal acceleration = ?
Process
Find the horizontal force
cos Ф = adjacent side / hypotenuse
adjacent side = hypotenuse x cosФ
adjacent side = 71 x cos 56
a.s. = 39.70 N
Newton's second law
F = ma
a = F/m
a = 39.7 / 20
a = 1.99 m/s²
Answer:
The flow rate is 
Explanation:
From the question we are told that
The velocity is 
The diameter of the pipe is 
The radius of the pipe is mathematically represented as
substituting values
The flow rate is mathematically represented as
Where is the cross-sectional area of the pipe which is mathematically evaluated as
substituting values
So
Answer:
x₁ = 58.09 m
Explanation:
Displacement is calculated by finding the final distance away from a point then subtracting the initial distance.
Given that initial position of object is x=25.89 m
Displacement Δx=32.2 m
Final position x₁=?
Δx = x₁-x
32.2= x₁-25.89
32.2+25.89 = x₁
58.09 m =x₁
