Explanation:
It is given that,
Mass of the Cadillac,
Speed of Cadillac, (towards north)
Mass of Volkswagen,
The cars stuck together and slid to a halt, leaving skid marks angled 35 degrees north of east.
According to the law of conservation of momentum,
The momentum along x axis, ............(1)
The momentum along y axis, ...........(2)
From equation (1) and (2) it is clear that,
So, the Volkswagen going just before the impact is 8.72 m/s. Hence, this is the required solution.
Answer:
kilogram and kg is the symbol
Explanation:
Hey y'all <3
Answer:
A magnetic field pulls and pushes electrons in certain objects closer to them, making them move. Metals like copper have electrons that are easily moved from their orbits. If you move a magnet quickly through a coil of copper wire, the electrons will move - this produces electricity.
Hope this helped <3
Draw the free body diagram for the mass W2.
In it the only forces that appear are W2 (downward) and the Tension of the cable A (upward), TA
Net force = 0 => W2 = TA
Then TA = 200 N
The capacitor is used to store electric charge.That is what makes capacitors special. <span>
The charge that flows into the capacitor is stored on the plate of the capacitor that the source voltage is connected to. </span>When current flows into a capacitor, the charges get “stuck” on the plates because they can’t get past the insulating dielectric. One plate is positively charged and the other negatively <span>The stationary charges on these plates create an </span>electric field. <span>When charges group together on a capacitor like this, the cap is storing electric energy just as a battery might store chemical energy.</span>
