To solve this problem we will apply the concepts of the Magnetic Force. This expression will be expressed in both the vector and the scalar ways. Through this second we can directly use the presented values and replace them to obtain the value of the magnitude. Mathematically this can be described as,
Here,
q = Charge
v = Velocity
B = Magnetic field
Our values are given as,
Replacing,
Therefore the size of the magnetic force acting on the bumble bee is
Answer:
6.13428 rev/s
Explanation:
= Final moment of inertia = 4.2 kgm²
I = Moment of inertia with fists close to chest = 5.7 kgm²
= Initial angular speed = 3 rev/s
= Final angular speed
r = Radius = 76 cm
m = Mass = 2.5 kg
Moment of inertia of the skater is given by
In this system the angular momentum is conserved
The rotational speed will be 6.13428 rev/s
Answer:
See below.
Explanation:
Cubit is a unit of length based on the length of the forearm from the elbow to the tip of the middle finger and usually equal to about 18 inches (46 centimeters).
It is an ancient unit of length used in ancient Egypt and is also known as "ancient Egyptian royal cubit."
