Answer:
a) is the speed of each proton
b)
Explanation:
Given:
radius of path of motion,
we know charge on protons,
magnetic field strength,
we've mass of proton,
a)
From the equivalence of magnetic force and the centripetal force on the proton:
where:
v = speed of the proton
is the speed of each proton
b)
Now the centripetal force on each proton:
Answer:
Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature.
Physics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world.
Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries.
Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.
Physics extends and enhances our understanding of other disciplines, such as the earth, agricultural, chemical, biological, and environmental sciences, plus astrophysics and cosmology - subjects of substantial importance to all peoples of the world.
Physics improves our quality of life by providing the basic understanding necessary for developing new instrumentation and techniques for medical applications, such as computer tomography, magnetic resonance imaging, positron emission tomography, ultrasonic imaging, and laser surgery.
The speed of the vehicle after the push is 2.7 m/s.
<h3>What is velocity?</h3>
velocity is the rate of change of displacement.
To calculate the velocity of the vehicle, we use the formula below.
Formula:
- v = √[2(W-W')/m]............... Equation 1
Where:
- W = work done by the pusher
- W' = Work done by friction
- m = mass of the car
From the question,
Given:
- W = 6500 J
- W' = 2000 J
- m = 1200 kg
Substitute these values into equation 1
- v = √[2(6500-2000)/1200]
- v = √(7.5)
- v = 2.7 m/s
Hence, the speed of the vehicle after the push is 2.7 m/s.

Answer:
the distance between the submarine and the ocean floor is 11,250 m
Explanation:
Given;
speed of the wave, v = 1500 m/s
time of motion of the wave, t = 15 s
The time taken to receive the echo is calculated as;
Therefore, the distance between the submarine and the ocean floor is 11,250 m
