How do protons ever fuse together in the presence of the electromagnetic force? There is another force involved here called the

nuclear strong force. It is the strongest of all the forces, but it only acts over extremely small distances before it becomes too weak to matter. If protons and neutrons are able to get close enough to one another, the strong force provides a powerful attractive force that can bind them together in a nucleus, despite the electromagnetic force.

Answer:

The nuclei are moving fast with respect to one another

Explanation:

Protons are found in the nucleus together with the neutrons while the electrons normally revolve round it.

However the protons appears fused in a way when electromagnetic force is applied by the nuclei moving at a very fast speed. This fast speed helps to keep the supposed neutrons fused together.

In a standing wave, areas of destructive interference are the?
pentagon [3]

Answer: B. Nodes

Explanation:

Standing waves (so called because they seem to be immobile) occur when two waves interfere with the same frequency, amplitude but with different direction, along a line with a phase difference of half wavelength.  

In these waves there are two types of points:  

The <u>nodes</u>, which are points that remain motionless or stationary and do not vibrate. They are <u>due to the destructive interference of both waves when they meet.  </u>

The antinodes, which are points that vibrate with a maximum vibration amplitude. They are <u>due to the non-destructive interference of both waves</u>.

At a particular instant, a hot air balloon is 100 m in the air and descending at a constant speed of 2.0 m/s. at this exact inst
rewona [7]

Answer:

86.4 m  horizontal from landing spot

Explanation:

Find out how long before the ball hits the ground

 vertical speed  of ball = -2  m/s     gravity = - 9.81 m/s^2

find time to hit ground from 100 m  

          ( height will be<u> zero</u> when it hits the ground)

<u>0 </u>=  100  - 2 t  - 1/2 ( 9.81) t^2

        use Quadratic Formula to find t = 4.32 seconds

              horizontal speed of ball = 20 m/s  

in 4.32 seconds it will travel horizontally   20  m/s * 4.32 s = 86.4 m

A net force of 24 N is acting on a 4.0-kg object. Find the acceleration in m/s2.
Inessa [10]

Hi there!

We can use Newton's Second Law:
\Sigma F = ma

ΣF = Net force (N)
m = mass (kg)
a = acceleration (m/s²)

We can rearrange the equation to solve for the acceleration.

a = \frac{\Sigma F}{m}\\\\a = \frac{24}{4} = \boxed{6 \frac{m}{s^2}}

A badger is running at a speed of 1 m/s. If the badger moves that was for 2600 seconds, how far will the badger travel?
katen-ka-za [31]

Answer:

It would be 2600

Explanation:

M/S stands for meters per second. If it moved 1 meter for 2600 seconds, than it would be 2600. You just multiply 2600 by 1! I hope this helps :D
