The magnitude of the magnetic field is 7.27 x 10-6 T and its direction is perpendicular to the velocity of the proton.
The force experienced by a charged particle in a magnetic field is given by the equation F = q(v x B), where F is the force, q is the charge of the particle, v is the velocity of the particle, and B is the magnetic field.
Given the information provided in the question, we can set up the following equation:
1.60 1013 m/s2 = (q)(2.20 107 m/s) x B
To find the magnitude of the magnetic field, we can divide both sides of the equation by the velocity:
B = 7.27 x 10-6 T
To find the direction of the magnetic field, we know that the force on the proton is perpendicular to its velocity and the direction of the magnetic field. The direction of the magnetic field can be found using the right-hand rule which states that if you point your fingers in the direction of the velocity and then curl them in the direction of the force, your thumb will point in the direction of the magnetic field.

A focus mirror sculpture was opened in Rockefeller Centre in New York City in 2006. Standing three storeys tall and weighing 23 tonnes, its concave side faced the Rockefeller Centre and its convex side faced 5th Avenue.
A. What is the nature of the image of 5th Avenue?
B. Which property of concave mirror is utilised for using them as shaving mirrors?
C. A taxi on 5th Ave is located 38 metres from the convex side of this culture and its image is 1/5 the size of the taxi. Determine the focal length of the mirror.
D. Estimate the image size of the 270 metre tall Rockefeller Centre if it is located an estimated distance of 100 metres from the concave mirrors surface of focal length 10 metre.
A. The nature of the image of 5th Avenue in the mirror sculpture is that it is a virtual, upright, and smaller image. This is because the concave mirror is used to reflect light outwards, creating a virtual image that cannot be projected onto a screen.
B. The property of concave mirrors that is utilized for using them as shaving mirrors is their ability to form a smaller, magnified image. This is because concave mirrors have a negative focal length, which causes light rays to diverge and form a smaller image that is closer to the mirror.
C. To determine the focal length of the mirror, we can use the formula 1/f = 1/u + 1/v, where f is the focal length, u is the object distance (38 meters), and v is the image distance (unknown). We know that the image size is 1/5 the size of the object, so we can set v = -5u (since the image is virtual and inverted). Substituting these values into the formula and solving for f, we get f = -(5u^2)/4 = -(5(38^2))/4 = -4725/4 = -1181.25 meters.
D. To estimate the image size of the 270 meter tall Rockefeller Centre, we can use the formula: h' = -h * (u/f) where h' is the image height, h is the object height (270 meters), u is the object distance (100 meters) and f is the focal length (10 meters). Substituting these values in the formula, h' = -270 * (100/10) = -2700 meters. This means the image of the Rockefeller Centre would be 2700 meters tall, which is not possible because it's taller than the building itself. This is an indication that the image is not real and is a virtual image.
What is the difference between flat mirrors and curved mirrors?Unlike plane mirrors, spherical mirrors form images that are different in size from the size of the object.

A 26 kg crate initially at rest on a horizontal floor requires a 70 N horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor.
The coefficient of static friction between the crate and the floor is calculated to be 0.275.
The frictional force when an object moves on the horizontal surface is given as,
Ff = μ N
where, N is the normal force
μ is the coefficient of static or kinematic friction
If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal force are equal in magnitude.

A simple pendulum has a period of 3 seconds . If the value of ‘g’ is taken as 9.98 ms-2 calculate the length of the pendulum.
Answer: The length of the pendulum is approximately 2.495 meters.
Explanation:
The period of a simple pendulum is the time it takes for the pendulum to swing back and forth through one full oscillation. The period of a simple pendulum is related to the length of the pendulum and the acceleration due to gravity (g) by the formula:
Period = 2 * pi * sqrt(length / g)
In this case, you are given that the period of the pendulum is 3 seconds and the value of g is 9.98 ms-2. You can use these values to solve for the length of the pendulum using the formula above.
Substituting in the values given, you get:
3 = 2 * pi * sqrt(length / 9.98)
Solving for length, you get:
length = (3 / (2 * pi))^2 * 9.98
= 0.5^2 * 9.98
= 0.25 * 9.98
= 2.495
Therefore, the length of the pendulum is approximately 2.495 meters.

On looking vertically down into the water the black line appears to be closer that it really is
It is true that on looking vertically down into the water the black line appears to be closer that it really is.
What is refractive index?A material's refractive index, which is quantified, indicates how much a light path is bent or refracted when it penetrates that material.
The critical angle for total internal reflection and the amount of light that is reflected when it reaches the contact are both determined by the index of refraction.
Due to the refraction of light rays as they pass through water and into the air, an item seen in the water typically appears to be deeper than it actually is.
Since the angle subtended by the object is greater, it "appears" larger because the light's refraction away from the normal changes the angle at which the light appears at the eye.
Thus, the given scenario is true.

What is an explain acceleration?Rate of change in both speed and direction of motion over time. A point or object going straight forward is accelerated when it accelerates or decelerates. Even though the speed is constant, motion on a circle accelerates because of direction is always shifting
Calculation:We know that from newton's equation,
v² + u² = 2as
S = ut + 0.5 at²
Where, v = final speed
u = initial speed
a = acceleration
S = distance covered

Given, u = 0
So the equations becomes:
v² = 2as
S = 0.5 at²
Using these equations we get:
v² = 2a(0.5)at²
v² = a²t²
v = at
v/t = a

What is the relationship between torque and force lever arm length?
Torque is produced by multiplying the length of a lever arm by the force acting perpendicular to the lever arm. There are two conceivable orientations for the scalar quantity torque: clockwise and anticlockwise.
What is the result of the force times the lever arm?A torque is created when a force is applied perpendicular to a lever arm. The lever arm or moment arm is the length that extends perpendicularly from the pivot point, or the centre of rotation, to the point at which the force is applied. A torque is always defined with reference to a pivot point.
How can torque be multiplied?A torque multiplier multiplies the torque applied to the bolt with each gearing level. For instance, a 5:1 torque multiplier will result in an output.For example, a torque multiplier with a 5:1 ratio will result in an output at the shaft that is five times the torque, but the speed will only be one fifth of the original since no energy can be created.

N/kg is the same as m/s². From W=mg
making g subject ... you have g = W/m
where m is in kg and W is in N
hence we have N/kg

Press the hotspot that indicates the location that a string will experience the least tension during vertical circular motion. Assume that the speed of the ball remains constant.
which one will experience the least tension t3 t2 t1 or t4
The least tension will be experienced by T3
The weight of a moving object causes tension, which is the force applied along the length of a string, rope, or cable. The force that maintains an object moving in a circular direction when it is in a vertical circular motion is called tension. Perpendicular to the circle's radius, the tension in the string is pointed in the direction of the circle's centre.
Due to the centripetal force required to maintain the object moving in a circular motion, the tension in the string varies as the object moves in a vertical circle, with the highest tension occurring at the top of the circle and the least tension occurring at the bottom. In the given case, T3 will experience the least tension during vertical circular motion, assuming that the speed of the ball remains constant. This is because T3 is the point on the string that is closest to the circle's centre, and thus is subject to the least amount of tension as the ball moves in a vertical circle.
