Answer:

Just a little bit. You should not be on electronics all the time. I know some people that are so addicted to there electronics that they won't even hang out with people. If you are at the point where you think about things other than school, friends, and family...you should think about getting off of your electronics and go play with a neighborhood friend outside, or have a sleepover! Your whole life should not count on your phone, iPad, or your laptop.

Explanation:

Hope this helps! No recorces included in this writing.

Answer:

(I will talk in my opinion only)

electronics do harm our mental health but they are also helpful ones like mobile both a boon and a curse

physical health is greatly affected and it's something no need to explain

social ( for me ) my only place to be social and talk people is brainly so for me mobile is very important

A spring of spring constant k is attached to a support at the bottom of a ramp that makes an angle θ with the horizontal. A bloc

Nikitich [7]

Answer:

$x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}$

Explanation:

From the law of conservation of energy

Energy lost by the spring, W=Kinetic energy gained, KE+Potential energy gained, PE+Work done by friction, Fr

$0.5kd^{2}=0.5mv^{2}+mgLsin\theta+\mu_{k}mgcos\theta x$

$x(mgsin\theta+\mu_{k}mgcos\theta)=0.5kd^{2}$

$x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}$

The required distance from A to B is $x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}$

b) The depth of a wrecked ship is 1000 m below sea level. A ship transmits a wave of frequency 50 kHz and receives an echo 2.4 s

alexandr402 [8]

The speed of the wave in water is 833.33 m/s

The given parameters;

depth of the wrecked ship, d = 1000 m

frequency of the wave transmitted, f = 50 kHz

time of motion of the echo, t = 2.4 s

The speed of the wave in water is calculated by applying echo equation as shown below;

$2d = velocity \times time\\\\velocity = \frac{2d}{time} \\\\velocity = \frac{2\times 1000 \ m}{2.4} \\\\velocity = 833.33 \ m/s$

Thus, the speed of the wave in water is 833.33 m/s

A secant and a tangent meet at a 90Ă‚Â° angle outside the circle. What must be the difference between the measures of the interc

kozerog [31]

The difference between the measures of the intercepted arcs of the given circle is 45°.

A circle is defined as the set of points in a plane equidistant to each, such that it forms a closed two-dimensional figure, which is known as a circle.

A line intersecting a circle at a minimum of two distinct points is known as a secant and the line touching the circle at only one point, is known as the tangent of a circle.
The intercepted arc is the section of the circumference of a circle such that it is either encased by two chords or a line segment, meeting at a single point.

We are given that the angle subtended by secant and tangent, outside the circle is,

$\theta =90^{\circ}$
