Ok. Thanks!

Here is the scenario: At t=0s, The body has a forward force of 2250N and a frictional force of 1000N F res = 1250N At t=1s or any time in the future, The body will still have a forward force of 2250N and a frictional force of 1000N F res = 1250N Will it have a constant velocity or...

Homework Statement There is a body of mass 500kg accelerating at 2.5ms^-2. It experiences a frictional force of 1000N. Homework Equations Resultant Force = ma The Attempt at a Solution Resultant Force = (500)(2.5)N = 1250N The body is moving forward with a net force of 1250N A...

The delay cannot be calculated if the satellite is not perfectly synchronised with the receiver. The article states that both starts transmitting PRN at midnight but their time needs to be synchronised first. The time is sent via radio waves and so there will be a delay and it will not be...

. In a nutshell, the receiver looks at incoming signals from four or more satellites and gauges its own inaccuracy. In other words, there is only one value for the "current time" that the receiver can use. The correct time value will cause all of the signals that the receiver is receiving to...

@Drakkith I knew that but how does it calculate the time of travel of the signal if the gps receiver only receives signals?

Well to figure out where you are requires the time of travel of the signal first. If the gps receive worked 2 way, I understand how it could work: the satellite bounce off the signal of the receiver like how a sonar works to calculate the time difference. But the gps is only a receiver and I...

Thanks tiny-tim and rude man. I understood it!

The GPS satellite has an atomic clock which sychronizes with the receiver. But when the receiver gets the time, it is delayed as it travelled. So when its 08h 00min 05s in the satellite, the receiver gets maybe 08h 00min 03s. The time of travel of the signal is 2s but how will the receiver...

Th book says A :(

Sorry, its one component to the left and another one upwards. Is it C?

One component to the right and another one upwards. Is the answer C?

Since the current is from X to Y, a north pole will be induced near the compass. I would say that the compass needle will point towards the solenoid but it says that the field strength is equal to that of Earth's magnetic field. I can only eliminate answer D. Then, I am lost. The answer is A...

A compass is placed near a solenoid. It is closer to the North pole generated by the coil. The magnetic north is 90 deg relative to the compass and the solenoid. The strength of the solenoid is equal to the strength of the magnetic north. In which direction will the compass needle point?
