Answer:
or 
.
Explanation:
<u>Given:</u>
- Charge on the particle at origin = Q.
- Mass of the moving charged particle,
- Charge on the moving charged particle,
- Distance of the moving charged particle from first at t = 0 time,
- Speed of the moving particle,
For the moving particle to circular motion, the electrostatic force between the two must be balanced by the centripetal force on the moving particle.
The electrostatic force on the moving particle due to the charge Q at origin is given by Coulomb's law as:
where, 
is the Coulomb's constant having value 
The centripetal force on the moving particle due to particle at origin is given as:
For the two forces to be balanced,
In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation. Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation. Without this acceleration, the object would move in a straight line.
In this sense, the acceleration is always changing due to centripetal acceleration.
Answer:
A. Acceleration
That the climate changes during the day and night high to low
Q = mass water x specific heat water x delta T.
<span>714,000 = mass water x specific heat water x 30.
Substitute specific heat water and solve for mass water.</span>
Answer:
41°
Explanation:
Kinetic energy at bottom = potential energy at top
½ mv² = mgh
½ v² = gh
h = v²/(2g)
h = (2.4 m/s)² / (2 × 9.8 m/s²)
h = 0.294 m
The pendulum rises to a height of above the bottom. To determine the angle, we need to use trigonometry (see attached diagram).
L − h = L cos θ
cos θ = (L − h) / L
cos θ = (1.2 − 0.294) / 1.2
θ = 41.0°
Rounded to two significant figures, the pendulum makes a maximum angle of 41° with the vertical.
