A 50 Kg football player is standing still when he experiences an inelastic collision with a 150 Kg football player who is traveling at 10 m/s. What is the velocity of the player immediately after the collision?

Answers

Answer 1
Answer:

Answer:

V = 7.5 m/s

Explanation:

Given that,

Mass of player 1, m₁ = 50 kg

Mass of player 2, m₂ = 150 kg

50 kg player stands still and 150 kg player is traveling at 10 m/s

We need to find the velocity of the player immediately after the collision. As the inelastic collision occurs. The linear momentum will remain conserved. After the collision, let they move with a constant velocity say V.So,

m_1u_1+m_2u_2=(m_1+m_2)V\n\nV=(m_1u_1+m_2u_2)/((m_1+m_2))\n\n=(150* 10)/((50+150))\n\n=7.5\ m/s

So, the velocity of the player immediately after the collision is 7.5 m/s.

The star is a ball of hot gasescontaining different kinds of elements at different cores. It has a very hightemperature that radiates all throughout the galaxy. The star has fourmain parts; the core, photosphere, chromospheres and corona. The outer core ofa star located at the chromospheres contains mostly of hydrogen. Inside the hydrogenis helium then carbon, oxygen, neon, magnesium silicon and the inert gas. When astar releases energy it is due to the thermonuclear fusion of hydrogen intohelium. So the answer is fusion.

the answer is fusion

Joan makes the device shown in her science class.An illustration with a battery and ends labeled positive and negative. A wire is connected to the positive end of the battery and curls around an iron nail and connects back with the negative side of the battery.

What would happen to the magnetic field if she connects the battery in the opposite direction?

The field would stop.
The field would get stronger.
The field would reverse its poles.
The field would get weaker.

Answers

If she connects the battery in the opposite direction, the magnetic field would reverse its poles.

What is magnetic field?

The magnetic field is the region of space where an object experiences the magnetic force and obtain magnetic properties.

A wire is connected to the positive end of the battery and curls around an iron nail and connects back with the negative side of the battery. This arrangement will let the current flow from the positive end of the battery towards the negative terminal of the battery.

If the battery is connected in the opposite direction, the current will flow from negative to positive terminal.

Therefore, If she connects the battery in the opposite direction, the magnetic field would reverse its poles.

Answer:

The field would reverse its poles.

Explanation:

The current flow will reverse directions which will reverse the poles in the magnetic field created around the iron nail.

What is the difference between the deviation and refraction? ​

Answers

Answer:

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.

Which wave source can travel through the vacuum of space?

Answers

I suppose any 'source' of waves could travel through space.
But the only waves that could leave their source and travel
through space away from it are electromagnetic ones.

Answer:

ondas mecánicas,ondas electromagnética .

Explanation:

ondas mecánicas, como las ondas de agua de sonido, temblores del terremoto y, necesitan un medio material a través del cual viajar. Las ondas electromagnéticas, incluyendo rayos X, ondas de radio y luz visible, pueden viajar a través del vacío del espacio vacío. Estas ondas se mueven a la velocidad de la luz y consisten de vibrar campos eléctricos y magnéticos orientados en ángulos rectos entre sí.
