Answer:
1 true, 2 true, 3 false, 4 false and 5 true
Explanation:
The magnetic field lines are used to graphically represent the magnetic field,
1 true. Because the field line is a graphic representation of the magnetic field
2 true leave one pole and reach another, there are no magnetic monopoles
3 false. The density of the lines gives an idea of the strength of the field, they are dense where the field is greater
4 false. The magnetic force is perpendicular to the field and therefore to the field lines
5 true. With the same experimental conditions, each field gives a unique force, if the lines cross different fields they would give the same force.
You would get 13.7
mi/51mm=3.5mm/13mm
by solving it you will B13.7mm
Answer:
Position of the object at t = 5 s is centimeter
Explanation:
The position of object as a function of time can be represented as
It is given that at t seconds the position of the object is centimeter.
We will substitute these values to determine the value of
Velocity at initial stage when t seconds is
Position after seconds
Distance traveled by the ball is given by
here we know that
speed = 20 m/s
times = 0.25 s
now we have
so ball will travel 5 m distance in the given interval of time
