The magnitude of the electric field will be uniform over the surface of the sphere when the Gaussian surface is centered at the origin.

If the charge distribution is spherically symmetric, then the magnitude of the electric field |E→| will be the same (uniform) over the surface of the sphere when the Gaussian surface is centred at the origin.

This is because of the symmetry of the charge distribution, which implies that the electric field will have the same magnitude and direction at any point on the surface of the sphere that is equidistant from the origin.

The net electric flux through the surface of the sphere will also be the same since the flux depends only on the magnitude of the electric field and the area of the surface.

Therefore, in this case, the magnitude of the electric field will be uniform over the surface of the sphere when the Gaussian surface is centred at the origin.

48 m/s in terms of km/h is 720.8 km/h. In terms of m/min is 2880 m/min, in terms of km/s is 0.048 km/s and in terms of km/min is 2.88 km/min.

To solve this question, we need to understand some terms. The unit of velocity is measured in m/s. It can be expressed in different units of velocity.

1 km (kilometer) = 1000 meter

1 h (hour) = 3600 seconds

1 minutes = 60 seconds

To convert m/s into km/h,

48 m/s * 3600/1000 =  172.8 km/h

To convert m/s into m/min,

48 m/s * 60 = 2880 m/min

To convert m/s into km/s,

48 m/s ÷ 1000 = 0.048 km/s

To convert m/s into km/minutes,

48 m/s * 60 / 1000 = 2.88 km/min

Therefore, the 48 m/s expressed is 172.8 km/h, 2880 m/min, 0.048 km/s and 2.88 km/min.

https://brainly.com/question/21552920

48 m/s is equivalent to  172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

To express 48 m/s in different units of velocity:

km/h (kilometers per hour):

To convert m/s to km/h, we can use the conversion factor of 3.6 since 1 m/s is equal to 3.6 km/h.

48 m/s * (3.6 km/h / 1 m/s) = 172.8 km/h

Therefore, 48 m/s is equivalent to 172.8 km/h.

m/min (meters per minute):

To convert m/s to m/min, we can use the conversion factor of 60 since there are 60 seconds in a minute.

48 m/s * (60 m/min / 1 s) = 2880 m/min

Therefore, 48 m/s is equivalent to 2880 m/min.

km/s (kilometers per second):

Since 1 kilometer is equal to 1000 meters, to convert m/s to km/s, we divide the value by 1000.

48 m/s / 1000 = 0.048 km/s

Therefore, 48 m/s is equivalent to 0.048 km/s.

km/minute (kilometers per minute):

To convert m/s to km/minute, we first need to convert m/s to km/s (as calculated in the previous step) and then multiply by 60 to convert seconds to minutes.

0.048 km/s * 60 = 2.88 km/minute

So, 48 m/s is equivalent to 2.88 km/minute.

Hence, 48 m/s is equivalent to approximately 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

a. The third sphere must be placed between A and B, closer to A.

b.  the third sphere must be placed at 175 cm from the first sphere.

Since

Using Newton's law of universal gravitation, the net force on the first sphere on the third sphere is F = mAmC/x² where x = distance between sphere C and A

Also, the Force of attraction between there second sphere and the third sphere is F' = mBmC/(R - x)² where R = distance between mA and mB and x = distance between mA and mC.

Since the net force must be zero, then

F = F'

mAmC/x² = mBmC/(R - x)²

So, (R - x)²/x² = mB/mC/mAmC

(R - x)²/x² = mB/mA

Substituting the values of mA and mB into the equation, we have

(R - x)²/x² = 7/2

(R - x)²/x² = 3.5

(R - x)/x = √3.5

(R - x)/x = 1.87

R - x = 1.87x

R = x + 1.87x

R = 2.87x

x = R/2.87

x = 0.35R

Since x = 0.35R, the third sphere must be placed between A and B, closer to A.

Since the position of the third sphere is

So, x = 0.35 × 500 cm

The x-ray tube life may be extended by reducing exposure time, controlling temperature, and ensuring proper maintenance. These measures help in prolonging the tube's performance and minimizing wear.

X-ray tubes are essential components of x-ray machines, and their lifespan plays a crucial role in the efficient functioning of the equipment. Reducing exposure time can significantly decrease the amount of heat generated within the x-ray tube, thus reducing the wear on its components. Using the lowest possible exposure time that still provides adequate image quality is one way to extend the tube's life.

Temperature control is also important in preserving the x-ray tube's lifespan. The tube generates heat during operation, and excessive heat can damage its components. Ensuring that the equipment has adequate cooling mechanisms and is used in a temperature-controlled environment will help minimize heat-related issues and prolong the tube's life.

Lastly, proper maintenance of the x-ray tube is essential in extending its life. This includes regular cleaning and inspection of the tube, as well as following the manufacturer's guidelines for usage and care. By adhering to proper maintenance procedures, potential problems can be detected early, and appropriate measures can be taken to prevent further damage to the tube.

In conclusion, extending the life of an x-ray tube can be achieved through reducing exposure time, controlling temperature, and ensuring proper maintenance.

Driving in a straight line at a constant speed of 100 km/h represents a case in which you are not accelerating.

Driving in an orderly fashion at a steady speed of 100 kilometers each hour addresses a case in which you are not speeding up. Speed increase is characterized as the pace of progress of speed as for time. On account of driving in an orderly fashion at a steady speed, there is no adjustment of speed, so there is no speed increase.

Then again, going from 0 to 100 kilometers each hour in 10 seconds and banging on the brakes to grind to a halt at a stop give both include switches in speed around time, so they address instances of speed increase.

In the previous case, the speed increase is positive since the speed is expanding, while in the last option case, the speed increase is negative since the speed is diminishing.Traveling 100 kilometers each hour around a bend is likewise an illustration of speed increase, despite the fact that the speed might stay steady.

This is on the grounds that the course of movement is continually changing as the vehicle circumvents the bend, and any course adjustment addresses an adjustment of speed. Thusly, there is a relating speed increase towards the focal point of the bend.

The average speed can be defined as the total distance traveled by the object in a specific time interval. The average speed can be defined as a scalar quantity as it possesses only the magnitude and does not have any direction.

The average speed can be determined from the ratio of the total distance the object covers to the time taken to travel that distance.

The equation for average speed can be written as follows:

Average speed =  Total distance/Total time taken

Given, the distance covered by the swimmer = 50 m

Mass is the amount of matter that a body contains and weight is the action exerted by the force of gravity on the body.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

The weight is calculated as the product of the mass of the object and the value of the gravitational acceleration or gravity:

Weight= mass× gravity

The value of the acceleration constant on Earth is 9.8 m/s². The weight is proportional to the mass of the object. The unit of weight is expressed in Newton (N).

Where m = mass of the head of the golf club, m' = mass of the gulf ball, u = initial velocity of the head of the gulf club, u' = initial velocity of the gulf ball, v = final velocity of the head of a gulf club, v' = final velocity of the gulf ball

From the question,

Given: m = 151 g = 0.151 kg, u = 43.9 m/s, m' = 46 g = 0.046 kg, u' = 0 m/s (at rest), v = 28.2 m/s

Substitute these values into equation 1

0.151(43.9)+0.046(0) = 0.151(28.2)+0.046(v')

solve for v'

6.6289+0 = 4.2582+0.046v'
