Answer:
Consider our plane flying at a speed of 80 km/hr into a 40 km/hr crosswind. Its speed, relative to the ground, can be calculated by adding the two vectors as shown on the right. What happens to the speed of the plane as the crosswind increases in magnitude? Look at the animation on the right. It is obvious that the speed of the plane, relative to the ground, increases in magnitude.
Explanation:
Its the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System.
Magnetic lines of forces make a closed loop because there are no magnetic charges (monopoles). While electric <span>field lines end on electric charges, magnetic field lines have no objects on which they could end. This is why they must form loops. </span>
Answer:
(a) 3107.98 J
(b) 14530.6 J
Explanation:
mass, m = 3.56 kg
angular speed, ω = 179 rad/s
Moment of inertia of solid cylinder, I = 1/2 mr^2
where, m is the mass and r be the radius of the cylinder.
(a) radius, r = 0.330 m
I = 0.5 x 3.56 x 0.330 x 0.330 = 0.194 kgm^2
The formula for the rotational kinetic energy is given by
K = 0.5 x 0.194 x 179 x 179 = 3107.98 J
(b) radius, r = 0.714 m
I = 0.5 x 3.56 x 0.714 x 0.714 = 0.907 kgm^2
The formula for the rotational kinetic energy is given by
K = 0.5 x 0.907 x 179 x 179 = 14530.6 J
Doubling the amounts of both ammonia and ammonium chloride is the action
that will most likely strengthen the buffering capacity of a solution that contains
equal amounts of ammonia and ammonium chloride, and is buffered at a pH of 9.25.
