Xrayssssss because they are the closest to gamma rays, and they have the highest frequency
The roughness of the surface, the mass of the object, and the area of contact.
Answer:
What is the acceleration of an object moving at a constant speed?
The Meaning of Constant Acceleration
The data table above show an object changing its velocity by 10 m/s in each consecutive second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second.
Answer:
Length of the string, l = 0.486 meters
Explanation:
It is given that,
Mass of the string,
Tension in the string, T = 120 N
Frequency of transverse wave, f = 260 Hz
Wavelength of the wave,
The speed of a transverse wave (v) is given by :
........(1)
<em>Where,</em>
Also, speed of a wave, .........(2)
From equation (1) and (2) :
l = 0.486 m
So, the length of the string is 0.486 meters. Hence, this is the required solution.
Answer:
B. They show the pattern made by the magnetic field lines around the
magnets
Explanation:
Using iron fillings, the pattern of the magnetic field lines around a bar magnet can be known.
Magnetic field lines are the line of force around a bar magnet.
- These iron fillings will trace the pattern of the magnetic field around the magnet.
- The domains of the iron fillings begins to align and orient with that of the prevailing magnetic field around.
- Those areas with the strongest force will attract more fillings and those far away will attract lesser fillings.
