Answer:
"Gravitational force and the acceleration force" are the forces that are acting on a passenger while going through a loop.
Explanation:
When the passengers reach the top of the loop, The force of the car's acceleration pushes all the passengers off the seat and towards the center of the loop. On the other hand the inertia will try to push the passengers back into the seat. The gravity as well as the acceleration will tend to push the passenger in opposite direction with approximately equal force, which will create a feeling of being mass-less or we can call it weightlessness.
Answer:
λw = 450 nm
λg = 402 nm
Explanation:
Frequency of a wave is defined as the number of vibrations coming out of the source in one second.
The frequency of a wave is the fundamental property of the source.
The relation among the wavelength, wave velocity and frequency is given by
wave velocity = frequency x wavelength
Frequency is constant while the velocity and wavelength changes.
wavelength in air, λa = 600 nm
Let the wavelength in water is λw.
speed of light in air, c = 3 x 10^8 m/s
speed of light in water = 75 % of c = 0.75 x 3 x 10^8 = 2.25 x 10^8 m/s
speed of light in plexglass = 67 % of c = 0.67 x 3 x 10^8 = 2.01 x 10^8 m/s
λw = 450 nm
λg = 402 nm
Answer:
- Current cannot flow through a circuit when the switch is OPEN
- Current flows through a circuit and all of the bulbs are lit only when the Switch is CLOSE
Explanation:
In a series connected electrical circuit as also seen in all electrical Circuit the switch allows the flow of Electricity through out the circuit therefore causing the lighting of bulbs and also other electrical appliances to receive electricity.
When the switch is Open the flow of electricity in the circuit is disrupted while when the Switch is closed it allows the flow of electricity seamlessly through out the circuit. there are different types of switches but the most important is the MAIN SWITCH because it is used to shutoff electricity completely from the entire circuit during emergencies or repairs.
Answer: D. one meter in front of the source
Mercaptan is a foul smelling gas which is added to the natural gas such as butane or propane. As, the natural gas is colorless and odorless, the mercaptan is added to detect the gas. It is added to detect the leakage of the natural gas. The gas sensors are able to detect the flow or leakage of gas at various locations but the maximum concentration of the natural gas containing the mercaptan can be found in one meter in front of the source. The source exhibit maximum concentration of the natural gas along with the mercaptan.
Answer:
independent” variable goes on the x-axis (the bottom, horizontal one) and the “dependent” variable goes on the y-axis (the left side, vertical one).
