Answer:
Detection of x-rays from a binary star undergoing mass exchange, where mass of component star can be determined.
Answer:
microwaves
Explanation:
Electromagnetic waves consist of waves of different wavelengths. Among the choices given, waves are ordered for increasing wavelengths as follows:
gamma rays --> ultraviolet waves --> infrared waves --> microwaves
So, microwaves are the waves with the longer wavelength among the given choices. This is the reason why they are used by the cell phone companies: in fact, since they have longer wavelengths, microwaves can travel longer distances without being absorbed by objects or obstacles, and so they are more reliable for broadcasting and telecommunications.
120 km/3 hours. 40/1=?/3 1x3=3 hours so 40x3=120 km
In a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.
To find the answer, we have to know more about the transformer.
<h3>
How transformer works?</h3>
- An item utilized in the transfer of electric energy is a transformer.
- AC current is used for transmission.
- It is frequently used to modify the supply voltage between circuits without altering the AC frequency.
- The fundamentals of mutual and electromagnetic induction govern how the transformer operates.
- Magnetic field through the primary coil changes when primary coil current varies. the iron core of the secondary coil likewise has a magnetic field.
- EMF is therefore generated in the secondary coil.
Thus, we can conclude that, in a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.

Answer:
Magnetic force, 
Explanation:
It is given that,
Velocity of proton, 
Angle between velocity and the magnetic field, θ = 53°
Magnetic field, B = 0.49 T
The mass of proton, 
The charge on proton, 
The magnitude of magnetic force is given by :
So, the magnitude of the magnetic force on the proton is 
. Hence, this is the required solution.
