Explanation:
Since, it is given that one hand completes 3.19 vibrations in 8.46 sec. Therefore, in one second the number of vibrations will be as follows.
= 0.377 vibrations
Hence, frequency (f) = 0.38 Hz
Now, formula to calculate the speed is as follows.
v =
or,
=
= 1.57 cm
Thus, we can conclude that the wavelength is 1.57 cm.
The translational speed v is given by,
Here, is the angular velocity and is the radius.
The angular distance is given by,
Here, is the angular velocity and is the time.
The translational distance covered is,
Here, is the velocity and is the time.
Centripetal acceleration is given by,
Here, is the velocity and is the radius.
Answer:
a) a = 0
b) W = 29.72 N
Explanation:
a)The acceleration of an object is defined as the change of its speed with respect to a time interval, Because the briefcase remains at rest, its acceleration (a) is zero.
a=0
b) Calculation of the weight of the briefcase
The formula to calculate the weight is the following:
W= m*g Formula (1)
Where:
W : is the weight in Newtons (N)
m : is the mass in kilograms (kg)
g : is the acceleration due to gravity in meters over second square (m/s²)
Data
m=3.03 kg : mass of the briefcase
m=9.81 m/s² : acceleration due to gravity
We replace data in the formula (1)
W= m*g = 3.03 kg * 9.81 m/s²
W= 29.72 N
In a magnetic field, it would require the thing that passes through it to have all their electrons paired up for it to be unaffected or repulsed. And if there is an empty orbital or an unpaired electron, it’ll be attracted. Sunlight can’t have these properties, it has no charge or mass
Answer:
4.545454 seconds
