The ball may attracted to the magnet.

<h3>How can we understand that the hanging ball will be attracted to the magnet or not?</h3>

From the question, we understand that the ball is attracted by the north pole of the bar magnet, then the bar magnet flipped over and the south pole is brought near the hanging ball.
As we know, in this type of experiments of bar magnet most of the times the ball is made out of steel.
Steel is a magnetic material.
Magnetic materials gets attracted to the magnet at both the North and South pole.
This can be compared to how neutral objects also gets attracted to the positively and negatively charged rods through the Polarization force.

So, If the bar magnet is flipped over and the south pole is brought near the hanging ball, The ball will be attracted to the magnet.

When a plane flies with the wind, it can travel 1575 miles in 3.5 hours. when the plane flies in the opposite direction, again

Zepler [3.9K]

When plane is flying along the wind then we can say

$V_{plane} + v_{wind} = \frac{distance}{time}$

$V_{plane} + v_{wind} = \frac{1575}{3.5}$

$V_{plane} + v_{wind} = 450 mph$

Now when its going against the wind the speed is given by

$V_{plane} - v_{wind} = \frac{distance}{time}$

$V_{plane} - v_{wind} = \frac{1575}{4.5}$

$V_{plane} - v_{wind} = 350 mph$

Now by the above two equations we will have

$V_{plane} = 400 mph$

$v_{wind} = 50 mph$

a student drops an object from the top of a building which is 19.6 m high. How long does it take the object to fall to the groun

zubka84 [21]

Here's a formula that's simple and useful, and if you're really in
high school physics, I'd be surprised if you haven't see it before.
This one is so simple and useful that I'd suggest memorizing it,
so it's always in your toolbox.

This formula tells how far an object travels in how much time,
when it's accelerating:

   Distance = (1/2 acceleration) x (Time²).

   D = 1/2 A T²

For your student who dropped an object out of the window,

   Distance = 19.6 m
   Acceleration = gravity = 9.8 m/s²

D = 1/2 G T²

    19.6 =   4.9   T²

Divide each side by 4.9 :    4 =   T²

Square root each side:    2 =   T

When an object is dropped in Earth gravity,
it takes 2 seconds to fall the first 19.6 meters.

In a carnival booth, you can win a stuffed giraffe if you toss a quarter into a small dish. the dish is on a shelf above the poi

Georgia [21]

components of the speed of the coin is given as

$v_x = v cos60$

$v_x = 6.4 cos60 = 3.2 m/s$

$v_y = vsin60$

$v_y = 6.4 sin60 = 5.54 m/s$

now the time taken by the coin to reach the plate is given by

$t = \frac{\delta x}{v_x}$

$t = \frac{2.1}{3.2}$

$t = 0.656 s$

now in order to find the height

$h = vy * t + \frac{1}{2} at^2$

$h = 5.54 * 0.656 - \frac{1}{2}*9.8*(0.656)^2$

$h = 1.52 m$

so it is placed at 1.52 m height

15. You are watching a baseball game on television that 15

Gre4nikov [31]

Answer:

t_total = 6.99 s

Explanation:

It asks us how long it takes to hear the sound, for this we must look for the time (t₁) it takes for the sound to reach the microphone, the time it takes for the video signal (t₂) to reach the television and the time (₃) it takes for the TV sound to reach us, so the total delay time is

t_total = t₁ + t₂ + t₂

we look for t1, it indicates that the distance x = 22m

v = x / t

t = x / v

t₁ = 22/343

t₁ = 6.41 10-2 s

time t₂

t₂ = 4500 103/3 108

t₂ = 1.5 10-5 s

time t₃

t₃ = 2/343

t₃ = 5.83 10⁻³

Total time is

t_total = t₁ + t₂ + t₃

t_total = 6.41 10⁻² + 1.5 10⁻⁵ + 0.583 10⁻²

t_total = 6.99 s
