Answer:
Magnetic field will be ZERO at the given position
Explanation:
As we know that the magnetic field due to moving charge is given as
so here we know that for the direction of magnetic field we will use
so we have
so magnetic field must be ZERO
So whenever charge is moving along the same direction where the position vector is given then magnetic field will be zero
Doppler Shift lets you see a star A. Move back and forth
<h3>What is Doppler Shift?</h3>
This refers to the frequency change of a wave in relation to an observer as it moves back and forth.
Hence, we can see that the thing which astronomers can learn from the Radial Velocity Method is D. Period of orbit and minimum mass of a planet as it measures the wavelengths of absorption lines in its spectrum.

#SPJ1
The maximum allowable torque must correspond to the allowable shear stress for maximization. To solve this, we use the torsion formula:
Max. Allowable Shear Stress = Maximum Torque ÷ Cross-Sectional Area
8 x 10^6 Pa = Maximum Torque ÷ pi*(d/2)²
Maximum Torque = 8 x 10^6 Pa * pi*(0.06/2)² m²
Maximum Torque = 22,619.47 J or
Maximum Torque = 22.62 kJ
As for the second question, I have no reference figure so I am unable to answer it. I hope I was still able to help you, though.
Answer:
T = 98 N
Explanation:
The gravity of the earth is known to be 9.8 m/s²
Data:
- m = 10 kg
- g = 9.8 m/s²
- T = ?
Use formula:
Replace and solve:
The tension in the rope is <u>98 Newtons.</u>
