Answer:true,because velocity is directly proportional to speed or velocity
Explanation:
Velocity = frequency x wavelength
The velocity or speed varies directly with the frequency, so as the frequency is increased, the velocity or speed is also increased
This would be called elevation
Answer:
During the experiment, alpha particles bombarded a thin piece of gold foil. The alpha particles were expected to pass easily through the gold foil. ... The discovery of the nucleus was a result of Rutherford's observation that a small percentage of the positively charged particles bombarding the metal's surface...

Answer:
The angular speed and tangential speed are 58.69 rad/s and 7.92 m/s.
Explanation:
Given that,
Radius = 0.344 m
Speed v= 20.1 m/s
(I). We need to calculate the angular speed
Firstly we will calculate the time
Using formula of time
The angular velocity of the tire
Now, using formula of angular velocity
(II). We need to calculate the tangential speed of a point located 0.135 m from the axle
The tangential speed
Where,
r = distance
= angular velocity
Put the value into the formula
Hence, The angular speed and tangential speed are 58.69 rad/s and 7.92 m/s.
