4.266 m is the radius of the circular path the electron follows.
Given
Speed of electron (v) = 7.5 × 10⁶ m/s
Earth's Magnetic Field (B) = 1 × 10⁻⁵ T
We already know that
Mass of electron (m) = 9.1 × 10⁻³¹ kg
Charge on electron (q) = 1.6 × 10⁻¹⁹ C
According to the formula
Radius of circular path(r) = mass on electron × speed/ Charge × Magnetic field
Radius of circular path(r) = m × v/q × B
Put the values into the formula
r = 9.1 × 10⁻³¹ × 7.5 × 10⁶/ 1.6 × 10⁻¹⁹ × 10⁻⁵
On solving, we get
r = 4.266 m
Hence, 4.266 m is the radius of the circular path the electron follows.

Answer:
Two wave will be coherent when they have the wavelength, amplitude, and phase of the constituent wave forms must be identical.
Where as interference is the addition of two wave considering the mathematical sense while adding them.
when two wave of same sense add together they for constructive interference. like two +ve sense or -ve sense will form constructive interference.
when the are are of different sense the form destructive interference. like one positive wave added with -ve one.
Answer:
The gram is the basic unit of measurement
Explanation:
You use it to weigh small items such as sugar, flour, coffee, and other items that are similar.
If you want to measure in grams using a scale is the most accurate solution.

Answer:
242 lts de fuel
Explanation:
We know density of fuel (is variable) but we can say that is close to 1 Kg/lts.
If we have 110 pounds over maximun certificated gross weight, we need to get rid of that 110 pounds or 110 * 2.2 = 242 Kgs
Now by rule of three
If 1 lt weight 1 kg.
x 242 kgs
x = 242 lts de fuel
