Answer:
v = 4,244,699 m/s = (4.245 × 10⁶) m/s
Explanation:
The electric force on the proton is given by
F = qE
where q = charge on the proton = (1.602 × 10⁻¹⁹) C
E = Electric field = 720,000 N/C
F = (1.602 × 10⁻¹⁹ × 720000)
F = (1.153 × 10⁻¹³) N
But this force will accelerate the proton in this magnetic field in a form of trajectory motion.
We can obtain the acceleration using Newton's first law of motion relation
F = ma
m = mass of a proton = (1.673 × 10⁻²⁷) kg
a = (F/m)
a = (1.153 × 10⁻¹³)/(1.673 × 10⁻²⁷)
a = 68,944,411,237,298 m/s²
a = (6.894 × 10¹³) m/s²
This acceleration directs the proton from the positive plate to the negative plate, covering a distance of y = 0.006 m (the distance between the plates)
Using Equations of motion, we can obtain the time taken for the proton to move from the rest at the positive plate to the negative one.
u = initial velocity of the proton = 0 m/s
y = vertical distance covered by the proton = 0.006 m
a = acceleration of the proton in this direction = (6.894 × 10¹³) m/s²
t = time taken for the proton to complete this distance = ?
y = ut + (1/2) at²
0.006 = 0 + [(1/2)×(6.894 × 10¹³)×t²]
0.006 = (3.447 × 10¹³) t²
t² = (0.006)/(3.447 × 10¹³)
t² = 1.741 × 10⁻¹⁶
t = (1.32 × 10⁻⁸) s
Then we can then calculate the minimum speed to navigate the entire length of the plates without hitting the plates.
v = ?
x = 0.056 n
t = (1.32 × 10⁻⁸)
v = (x/t)
v = (0.056)/(1.32 × 10⁻⁸)
v = 4,244,699 m/s = (4.245 × 10⁶) m/s
Hope this Helps!!!
Answer:
v = 9.09×10⁵m/s
Explanation:
Given
d = the distance between plates = 0.6cm = 0.006
E = Electric field strength = 720000N/C
m =mass of the proton = 1.67 ×10-²⁷ kg
The
Electric potential energy of the field is converted into the the kinetic energy of the proton.
So
qV = 1/2mv²
But V = Ed
So q(Ed) = 1/2mv²
v² = 2qEd/m
v = √(2qEd/m)
v = √(2×1.6×10-¹⁹×720000×0.006/1.67×10-²⁷)
v = 9.09×10⁵m/s
Answer:
0.58 J
Explanation:
We know that Total energy is conserved.
Initial Kinetic energy + Initial potential energy = final kinetic energy+ final potential energy + dissipated heat energy
Initial kinetic energy = 0 ( magnet is at rest initially)
Initial Potential energy = m g h = (0.20 kg)(9.81 m/s²)(0.35 m) = 0.69 J
Final kinetic energy = 0.5 m v² = 0.5 ×0.20 kg × 1.10 m/s = 0.11 J
Final potential energy = 0
∴ Dissipated heat energy = (0.69 -0.11) J = 0.58 J
Answer:
Ohms law
Explanation:
Which states that the current flowing through any cross-section of the conductor is directly proportional to the potential differenceapplied across its end, provided physical conditions like temperature and pressure remain constant.
Answer:
The correct answer is d. tension pneumothorax.
Explanation:
The increasing build-up of air that is in the pleural space is what we call the tension pneumothorax and this happens due to the lung laceration that lets the air to flee inside the pleural space but it does not return.
Answer:
Improvement in observational, and exploratory technology
Rapid increase in knowledge
International collaboration
Explanation:
Our knowledge of the solar system has increased greatly in the past few years due to to some factors which are listed below.
Improvement in observational, and exploratory technology: In recent years, developments in technology has led to the invention of advanced observational instruments and probes, that are used to study the solar system. Also more exploratory units are now developed to go out into the solar system and gather useful data which is then further processed to yield more results about our solar system.
Rapid increase in knowledge: The past few years has seen an increased number of theories proposed to explain phenomena in the solar system. Some of these theories have been seen to be accurate under experimentation, leading to newer and fresher insights into our solar system. Also, new experiments and research are carried out, all these leading to an exponential growth in our knowledge of the solar system.
International Collaboration: The sharing of knowledge by scientists all over has led to a better, quick understanding of the solar system. Also, scientists from different countries, working together on different experiment and data sharing regarding our solar system now allows our knowledge of the solar system to deepen faster.
2)accelerating to a comfortable speed.
3) Carring the boxes to the tomato display at constant speed.
4)decelerating to a stop.
5) lowering the boxes slowly to the floor.
During which of the five segments of the job does the stock person do positive work on the boxes?
A) (2) and (3)
B(1) and (2)
C) (1) only
D) (1), (2), (4) and (5)
E) (1) and (5)
Answer:
B
Explanation:
Work done can be said to be positive if the applied force has a component to be in the direction of the displacement and when the angle between the applied force and displacement is positive.
In 1 and 2 work done is positive
a feeling of weightlessness?
Answer:
Astronaut in spacecraft while orbiting earth experience weightlessness because there is no gravity of earth or moon is acting on the body of an astronaut.
while on earth, we experience weight because the gravity of earth is acting on our body which is pulling us downward.
Both spacecraft and the astronauts both are in a free-fall condition.
