Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.
Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.
Same: Both forces act within an nucleus, or on a nuclear level.
Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects
The last one may be a bit of a stretch but I hope this helped a bit!
Momentum is a product of mass and the velocity of a body. The initial momentum is always equal to the final momentum during collisions between two bodies.
Therefore; M1U1 +M2U2 = M1V1+ M2V2, where m1 is the mass of tracey and m2 is the mass of jonas, while u is the initial velocity and v is the final velocity.
(32 ×0)+ (45×0) = (32 × v1) + (45 × 0.50)
0 = 32V1 + 22.5
32 V1 = -22.5
V1 = - 0.703 ( negative indicates difference in direction)
There, Tracey's speed will be 0.703 m/s
Answer:
B. develop hypotheses that will be subjected to empirical test.
Explanation:
The rational method of inquiry is most useful in the early stages of science to develop hypotheses that will be subjected to empirical test.
