Mr. Roentgen's x-rays allowed scientists to measure the size of the atom. The x-rays were small enough to discern the atomic clouds. This was done by scattering x-rays from atoms and measuring their size just as Rutherford had done earlier by hitting atoms with other nuclei starting with alpha particles.
Answer:
The angle between the magnetic field and the wire’s velocity is 19.08 degrees.
Explanation:
Given that,
Potential difference, V = 53 mV
Length of the wire, l = 12 cm = 0.12 m
Magnetic field, B = 0.27 T
Speed of the wire, v = 5 m/s
Due to its motion, an emf is induced in the wire. It is given by :
Here,
is the angle between magnetic field and the wire’s velocity
So, the angle between the magnetic field and the wire’s velocity is 19.08 degrees.
Answer:
Power= 6.84×10⁸ W
Explanation:
Given Data
Niagara falls at rate of=1.4×10⁶ kg/s
falls=49.8 m
To find
Power Generated
Solution
Regarding this problem
GPE (gravitational potential energy) declines each second is given from that you will find much the kinetic energy of the falling water is increasing each second.
So power can be found by follow
Power= dE/dt = d/dt (mgh)
Power= gh dm/dt
Power= 1.4×10⁶ kg/s × 9.81 m/s² × 49.8 m
Power= 6.84×10⁸ W
Answer:
Gravity.” or “Gravity causes the moon to orbit the earth.” “Acceleration due to gravity” is much more precise. It is the acceleration that an object experiences when it is dropped with no other external forces on it. ... Near the surface of the earth the acceleration due to gravity is about 9.8
