The radius of the path described by a proton moving at 175 km/s in a plane perpendicular to a 64. 6- mt magnetic field is 0.0657 meters. When a proton moves perpendicular to a magnetic field, it experiences a magnetic force.
A proton moving perpendicular to a magnetic field will experience a magnetic force that acts as a centripetal force, causing the proton to move in a circular path.
The radius of this path can be determined using the formula r = mv/qB, where m is the mass of the proton, v is its velocity, q is its charge, and B is the strength of the magnetic field.
Substituting the values given, we have
\(r = (1.67 \times 10^{-27} kg)(175 \times 10^3 \;m/s)/(1.6 \times 10^{-19} C)(64.6 \times 10^{-3} T)\)
r = 0.0657 m.
Therefore, the radius of the path described by the proton is 0.0657 meters.
In summary, when a proton moves perpendicular to a magnetic field, it experiences a magnetic force that causes it to move in a circular path. The radius of this path can be calculated using the formula r = mv/qB.
Given the mass, velocity, charge, and strength of the magnetic field, we can calculate the radius of the circular path, which in this case is 0.0657 meters.

what is the velocity of a wave that has a frequency of 200 Hz and a wavelength of 0.50 m
Answer:
The velocity of the wave is 100 m/s.
Explanation:
What is frequency of a 0.0004 m ultrasonic wave passing through human tissue? Assume speed of sound in human tissue is 1500 m/s. Formula f= v/¥
Given:
the speed of sound in human tissue is
\(v=1500\text{ m/s}\)the wavelength of the wave is
\(\lambda=0.0004\text{ m}\)Required: frequency of the wave.
Explanation:
to find the frequency of the wave we use the relation that is given by
\(f=\frac{v}{\lambda}\)Plugging all the values in the above relation, we get
\(\begin{gathered} f=\frac{1500\text{ m/s}}{0.0004\text{ m}} \\ f=3750000\text{ Hz} \\ f=3.75\text{ MHz} \end{gathered}\)Thus, the frequency of the wave is
\(3.75\text{ MHz}\)All other things being equal, current will be larger in a wire that has a larger value of.
All other things being equal, the current will be larger in a wire that has a larger value of conductivity. Conductivity is a measure of how easily a material allows electric current to pass through it. It depends on factors such as the material's composition and structure.
When a wire has a higher conductivity, it means that it offers less resistance to the flow of electric current. The flow of current is directly proportional to the voltage applied and inversely proportional to the resistance in the circuit, according to Ohm's law (I = V/R).
A wire with higher conductivity will have a lower resistance compared to a wire with lower conductivity. As a result, more current can flow through the wire with higher conductivity, given the same voltage.
For example, let's consider two wires made of different materials, with all other factors being the same. Wire A has a higher conductivity than wire B. When the same voltage is applied to both wires, wire A will allow more current to flow through it because it offers less resistance. Wire B, with lower conductivity, will have a higher resistance and therefore a smaller current.

The drawings show the mass and weight of four objects on different planets:
(see the picture)
(a)
On which of the four planets is the object with the largest mass?
The object with the highest mass is the one on planet D. This is because mass is a measure of the amount of matter an object contains, and is not affected by gravity. Therefore, although the weight of the object on planet D is lower than that of the other planets, its mass remains the same.
Weight, on the other hand, is a measure of the gravitational force acting on an object. Therefore, the weight of an object will vary on different planets due to different gravitational forces. As shown in the drawings, the object on planet A has the greatest weight, but nevertheless the greatest mass.

Two pro baseball players of the same height are testing how far they can throw. One players throws the ball at a 40.0 degrees angle to the horizontal. The ball leaves his hand at a speed of 36.1 m/s. How far does the ball travel before it lands in the other player's glove
Answer:
The distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Explanation:
Given;
angle of projection of the ball, θ = 40⁰
initial velocity of the ball, u = 36.1 m/s
The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;
\(R = \frac{u^2 sin(2\theta)}{g} \\\\R= \frac{36.1^2 \times sin(2\times 40)}{9.8} \\\\R = \frac{36.1^2 \times sin(80)}{9.8} \\\\R = 130.96 \ m\)
Therefore, the distance traveled by the ball before it lands in the other player's glove is 130.96 m.

which of the four forces makes paint cling to a wall ?which force makes adhesive sticky?which force makes wax to stick a car ?
Answer:
This question is incomplete
Explanation:
The question is incomplete because of the absence of options.
However, the force that makes a paint cling to a wall is adhesive force. Adhesive force is the force between two unlike substances like a liquid clinging to a solid surface.
The force between adhesives or glue is also the force that makes them sticky. This force is referred to as cohesive force. This is a force found in between similar molecules (unlike adhesive force found between dissimilar molecules).
The force that makes wax to stick to a car is electromagnetic force. This is a force between charged particles; whether they appear to be moving or not. These particles of opposite charges come together to form a neutral force. In this case, charged atoms of the car and the wax come together (which causes what we see as the wax sticking to the car).

If the students continue at the same speed, which statement describes the total distance traveled in 90 seconds?
Student #1 traveled 40 m, and Student #2 traveled 20 m.
Student #1 traveled 50 m, and Student #2 traveled 30 m.
Student # 1 traveled 75 m, and Student #2 traveled 45 m.
Student #1 traveled 65 m, and Student # 2 traveled 50 m.
If the students continue travelled at the same speed, the statement that describes the total distance traveled in 90 seconds is "student # 1 traveled 75 m, and student #2 traveled 45 m," hence option B is correct.
To find the total distance moved by each student in 90 seconds, it is required to find the distance covered per second and then multiply it by 90.
To find for student 1:
Distance traveled per second = Distance traveled in 60 seconds ÷ Time taken in 60 seconds:
= 50 m ÷ 60 s
= 0.833 m/s
Total distance traveled in 90 seconds = Distance traveled per second × Time taken in 90 seconds:
= (0.833 m/s) × 90 s = 75 m
For student #2:
Distance traveled per second = Distance traveled in 60 seconds ÷ Time taken in 60 seconds
= 30 m ÷ 60 s = 0.5 m/s
Total distance traveled in 90 seconds = Distance traveled per second * Time taken in 90 seconds
= (0.5 m/s) × 90 s = 45 m
Thus, the correct statement is: Student 1 traveled 75 m, and Student 2 traveled 45 m.

Conclusion for simple pendulum with aim to determine acceleration due to gravity
In conclusion, the experiment aimed to determine the acceleration due to gravity by measuring the period of a simple pendulum. The experiment was performed by measuring the length of the pendulum and recording the time for 10 oscillations. The data was then used to calculate the average period and subsequently, the acceleration due to gravity using the formula: g = (4π²L)/T².
Based on the results obtained, the acceleration due to gravity was found to be (9.79 ± 0.06) m/s², which is in good agreement with the accepted value of 9.81 m/s². The small discrepancy could be due to the experimental errors such as air resistance, friction and measurement errors.
Overall, the experiment was successful in determining the acceleration due to gravity using a simple pendulum and demonstrated the relationship between the period and the length of the pendulum.

if the sun was gradually compressed while maintaining its mass in order to form a black hole, how would the curvature of spacetime be affected at the location of the earth? if the sun was gradually compressed while maintaining its mass in order to form a black hole, how would the curvature of spacetime be affected at the location of the earth? compressing the sun would not form a black hole because a black hole needs to be at least 2-3 times the mass of the sun. it would not change because the mass of the sun is not changing. the curvature would become greater because a black hole has stronger gravity than the sun. the curvature would be reduced because the sun would get so much smaller.
Since the mass of the sun is not changing, the amount of gravity produced by the sun would remain the same.
This means that the curvature of spacetime at the location of the Earth would not be affected. This is because the amount of gravity produced by an object determines the curvature of spacetime; if the amount of gravity stays the same, then the curvature of spacetime would be unaffected.
Additionally, the mass of the sun is not large enough to form a black hole, which is why the curvature of spacetime at the Earth's location would remain the same even if the sun were compressed.
