Answers

Answer:

as we find the resultant of the magnetic field we get in the xy plane. Just perpendicular to this plane i.e. along z-axis the charge is moving. Hence the force acting on the charge will also be in the xy plane.

Net field = ./(0.078^2 +0.070^2) = 0.105 T

Angle with x axis is arc tan 0.070/0.072 = 44.2 deg

So the force acting on the moving charge is got by Bqv

0.105*5.5*10^-5 * 6*10^3 = 0.03465 N

So the angle inclined by this force with x axis will be 90+44.2 = 134.2

What is meant by Momentum?

The momentum of an object is defined as the product of mass and velocity of the object.

Mathematically, the momentum of an object is given as;

P = mv

where;

m is the mass of the object

v is the velocity of the object

The principle of conservation of linear momentum states that the total momentum of an isolated system is always conserved.

That is the sum of initial momentum of the system is equal to the sum of the final momentum of the system.

Mass of tiger , m = 34 kg .

Velocity of tiger , v = 8.5 m/s .

Substituting the above values in given formula,

P = mv

= 34 × 8.5

= 289 Kg m/s.

The Connecticut Energy of the tiger 289 Kg m/s.

Answer:

The kinetic energy of the tiger is 1228.25 J.

Explanation:

KE=1/2m*v^2

m=34

v=8.5

KE=1/2*34*8.5^2

KE=17*72.25

KE=1228.25 J
