Given that,
Mass of trackler, m₁ = 100 kg
Speed of trackler, u₁ = 2.6 m/s
Mass of halfback, m₂ = 92 kg
Speed of halfback, u₂ = -5 m/s (direction is opposite)
To find,
Mutual speed immediately after the collision.
Solution,
The momentum of the system remains conserved in this case. Let v is the mutual speed after the collision. Using conservation of momentum as :
![m_1u_1+m_2u_2=(m_1+m_2)V\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\V=\dfrac{100\times 2.6+92\times (-5)}{(100+92)}\\\\V=-1.04\ m/s](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3D%28m_1%2Bm_2%29V%5C%5C%5C%5CV%3D%5Cdfrac%7Bm_1u_1%2Bm_2u_2%7D%7B%28m_1%2Bm_2%29%7D%5C%5C%5C%5CV%3D%5Cdfrac%7B100%5Ctimes%202.6%2B92%5Ctimes%20%28-5%29%7D%7B%28100%2B92%29%7D%5C%5C%5C%5CV%3D-1.04%5C%20m%2Fs)
So, the mutual speed immediately after the collision is 1.04 m/s but in opposite direction.
Answer:
HEAT GENERATED FROM THE INTERIOR OF THE EARTH IS CALLED GEOTHERMAL ENERGY.
Explanation:
THE TEMPERATURE IN THE INTERIOR OF THE EARTH RISES STEADILY AS WE GO DEEPER.SOMETIMES THIS HEAT ENERGY MAY SURFACE ITSELF IN THE FORM OF HOT SPRINGS ..THIS HEAT ENERGY CAN BE USED TO GENERATE POWER.
Answer:
The value is ![f = 0.05 \ Hz](https://tex.z-dn.net/?f=f%20%20%3D%20%200.05%20%5C%20Hz)
Explanation:
From the question we are told that
The mass of the car is
The period of the circular motion is ![T = 20 \ s](https://tex.z-dn.net/?f=T%20%20%3D%20%2020%20%5C%20%20s)
The radius is ![r = 80 \ m/s](https://tex.z-dn.net/?f=r%20%3D%20%2080%20%5C%20%20m%2Fs)
Generally the frequency of the circular motion is
![f = \frac{1}{T }](https://tex.z-dn.net/?f=f%20%20%3D%20%20%20%5Cfrac%7B1%7D%7BT%20%7D)
=> ![f = \frac{1}{ 20 }](https://tex.z-dn.net/?f=f%20%20%3D%20%20%20%5Cfrac%7B1%7D%7B%2020%20%20%7D)
=> ![f = 0.05 \ Hz](https://tex.z-dn.net/?f=f%20%20%3D%20%200.05%20%5C%20Hz)
a)., b)., and c). are completely false.
There isn't a grain of truth among them.
In Physics, the technical definition of 'Work' is (force) times (distance).
Answer:
Yes, it is very helpful.
Explanation:
It's helpful since in a cell, plant or animal, there are a lot of different things. It's hard to memorize everything and know what they look like. Using a model can help you memorize everything better and even understand it better. If someone asked me where or what something was in a cell I think I would be able to recognize it better.
I hope this helps!
