Answer:
The current in third branch is 11 A.
Explanation:
incoming current in one branch = 18 A
outgoing current in the other branch = 7 A
let the current in the third branch is i.
According to the Kirchoff's fist law in electricity
incoming current = out going current
18 = 7 + i
i = 11 A
The current in third branch is 11 A.
Answer:
66.42 N
Explanation:
Torque is defined as the product of force and the perpendicular distance.
Where, r be the distance, f be the force and θ be the angle between the force vector and the distance vector
Case I :
F = 53 N, r = 28 cm = 0.28 m, θ = 90°
So,
case II :
F = ?, r = 0.28 m, θ = 53°
Let the force be F for the same toque.
F = 66.42 N
Thus, the force required is 66.42 N.
Answer:
It is important to have a range of tools that can measure all parts of the electromagnetic spectrum because electromagnetic spectrum have different radiations such as infrared, visible light, ultraviolet, radio waves, microwaves, X-rays and gamma rays. Each of these radiation requires different instrument for their measurement. So that's why a range of tools are needed to measure electromagnetic spectrum.
Given Information:
Mass = m = 500 kg
Acceleration = a = 10 cm/s²
Required Information:
Magnitude of rightward net force = F = ?
Answer:
Magnitude of rightward net force = 50 N
Explanation:
From the Newton's second law of motion
F = ma
Where m is the mass and a is the acceleration
To get force in Newtons first convert 10 cm/s² into m/s²
10/100 = 0.1 m/s²
F = 500*0.1
F = 50 N
Therefore, the magnitude of rightward net force acting on it is 50 Newtons.
Answer:
The third particle should be at 0.0743 m from the origin on the negative x-axis.
Explanation:
Let's assume that the third charge is on the negative x-axis. So we have:
We know that the electric field is:
Where:
- k is the Coulomb constant
- q is the charge
- r is the distance from the charge to the point
So, we have:
Let's solve it for r(3).
Therefore, the third particle should be at 0.0743 m from the origin on the negative x-axis.
I hope it helps you!
