Weight is the force acting on a bode weight =mass times gravity
Answer:
Visible waves can be seen by people.
Explanation:
Electromagnetic waves comprises of different kind of waves. It consists of cosmic waves, x-rays waves, gamma waves, ultra violet waves, visible waves, infrared waves, microwaves. Among these waves, depending upon the wavelength of each kind of waves, it is visible and invisible to naked eyes. Thus, visible waves are the one which can be seen by people in naked eyes. As the wavelength of these waves are in comparable to the eye sight, so it can be seen by people.
Answer:
B
Explanation:
In a common rail system, the fuel is distributed to the injectors from the rail where there is high pressure accumulation.High pressure fuel pump feds the rail and with the help of the start and end signals the injector is activated.For example in diesel common rail direct injection systems, the rail is connected to injectors using individual pipes in that the injectors work hand in hand with the fuel pump which ensures fuel injection timing and amount. Comparing this with early models, the fuel pump was responsible for timing, quantity and pressure.So power stroke in a modern common rail system does not only rely on single injection of pump but also has multiple injection events during combution process.
Answer:
![F = 4.096*10^18N](https://tex.z-dn.net/?f=F%20%3D%204.096%2A10%5E18N)
Explanation:
To solve this problem we need to apply the concept relate to Coulomb's law.
We know that the Force given by Coulomb is
![F = K \frac{q_1q_2}{r^2}](https://tex.z-dn.net/?f=F%20%3D%20K%20%5Cfrac%7Bq_1q_2%7D%7Br%5E2%7D)
Where ,
F= electrostatic force
q= electric charge
r= distance between charge centers
k= Coulomb constant = ![9.0*10^9 Nm^2/c^2](https://tex.z-dn.net/?f=9.0%2A10%5E9%20Nm%5E2%2Fc%5E2)
We have the values only to replace in the equation, then we have,
![F = (9.0*10^9)\frac{96000*96000}{4.5^2}](https://tex.z-dn.net/?f=F%20%3D%20%289.0%2A10%5E9%29%5Cfrac%7B96000%2A96000%7D%7B4.5%5E2%7D)
![F = 4.096*10^18N](https://tex.z-dn.net/?f=F%20%3D%204.096%2A10%5E18N)
