Answer:
0.48 kgm/s
Explanation:
= mass of the particle = 2.43 μg = 2.43 x 10⁻⁶ x 10⁻³ kg = 2.43 x 10⁻⁹ kg
= velocity of the particle = 1.97 x 10⁸ m/s
= momentum of the particle
momentum of the particle is given as
inserting the values
kgm/s
Answer:
Force pull the child up. With the springs and the weight when you jump.
Answer: Gravity slows the ball down as it goes up and eventually stops it from going up and starts to pull it back down to earth.
Explanation:
If dirt and grease were good conductors of electrical current, then we could make wire

dirt and grease on the wire can have a substantial impact on the connection, and can
even block the flow of current across the connection completely. Moreover, in the case
where the ends of the wires are to be soldered, solder does not adhere to dirty wire.
