Gravitational potential energy stored in cat= mgh ( m= mass of cat, h = height of cat from ground) = 7x9.8x3 = 205.8 J
<u>Record of magnetic reversals recorded in molten rock at mid-ocean ridges:</u>
Often in ocean, at the junction of two plates, lava often comes out of the junction because of the movement of plates away from each other as a result, forming a divergent plate boundaries. As the lava comes up, the magnetic minerals come along with it.
During the molten state, they arrange themselves along the magnetic poles of the earth. Then they gets solidified. As the magnetic reversals take place in earth, these rock can’t change the orientation, but they retain the data about the magnetic orientation of earth corresponding to the date of their formation.
Answer: - 0.75 m
Explanation: The displacement will be the sum of the slope of the graph within the given time. From time 8s to 16s, the slope m will be; Slope = (15 - 6) / (16 - 8) Slope = 9 / 8 From time 16s to 24s Slope = (15 - 0) / ( 16 - 2 Slope = -15 / 8 Displacement = 9/8 - 15/8 Displacement = -6/8
Displacement = - 0.75 m
Answer:
The acceleration of the proton is 1.403 x 10⁹ m/s²
Explanation:
Given;
speed of proton, v = 7.7 m/s
magnitude of magnetic field, B = 1.9 T
Magnetic force of moving proton is given by;
F = qvBsinθ
Centripetal force on the moving proton is given by;
where;
q is charge of the proton = 1.602 x 10⁻¹⁹ C
m is mass of proton = 1.67 x 10⁻²⁷ kg
Therefore, the acceleration of the proton is 1.403 x 10⁹ m/s²
