Answer:
53/14
Explanation:
average acceleration = (Vfinal -Vintial)/ time taken
Explanation:
The magnetic force acting on a current carrying wire in a uniform magnetic field is given by :

or

Where
is the angle between length and the magnetic field
The magnetic force is perpendicular to both current and magnetic field. It is maximum when it is perpendicular to both current and magnetic field.
So, the correct options are :
- The magnetic force on the current-carrying wire is strongest when the current is perpendicular to the magnetic field lines.
- .The direction of the magnetic force acting on a current-carrying wire in a uniform magnetic field is perpendicular to the direction of the field.
- The direction of the magnetic force acting on a current-carrying wire in a uniform magnetic field is perpendicular to the direction of the current.
Answer:
v = 66.4 m/s
Explanation:
As we know that plane is moving initially at speed of

now we have




now in Y direction we can use kinematics



since there is no acceleration in x direction so here in x direction velocity remains the same
so we will have



A. Between asteroids C and D because gravitational attraction is greatest with increased mass.
A ball is moving upwards and rightwards towards its peak. The ball .... since the only horizontal force acting upon it is a "left-ward" force.
