Answer:
10 m/s
Explanation:
Given:
Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]
Frequency of the vibrations (f) = 10¹² Hz
In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.
Therefore, the formula for maximum speed is given as:
Now, plug in the values given and solve for speed 'v'. This gives,
Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
Answer:
3.67 rad/s
Explanation:
L = Length of meter stick = 1 m
r = Distance at which the bullet will hit the stick =
m = Mass of bullet = 3 g
M = Mass of stick = 270 g
= Velocity of bullet = 250 m/s
= Velocity of bullet leaving = 140 m/s
Initial angular momentum
Final angular momentum of the system
Since, angular momentum is conserved we have
The angular speed is the stick spinning after the collision is 3.67 rad/s
Energy is in Joules ( J )
specific heat capacity is in ( Joules per Kilogram per degree Celsius) ( J/kg C )
Answer:
Speed is the time rate at which an object is moving along a path while velocity is the rate and direction of an object's movement
