An electron travels 1.92 m in 4.47 × 10−8 s. How fast is it traveling? Answer in units of m/s.

1 answer:

6 0

Speed = (distance covered) / (time to cover the distance).

= (1.92 meters) / (4.47 x 10⁻⁸ second)

= 42,950,000 meters/second (rounded to the nearest 10,000 m/s)

That's about 96.1 million miles per hour, or about 14% of the speed of light.

The two forces in each pair can either both act on the same body or they can act on different bodies. The two forces in each pai

Answer: The given statement is false.

Explanation:

According to Newton's third law of motion, every action has an equal and opposite reaction. So, when we apply force in one direction on an object then the object also applies a force in the opposite direction.

Hence, it is true that two forces in each pair of forces act in opposite directions.

For example, when we push a wooden box of 20 kg in the forward direction then the box will also apply a force in the opposite direction.

But the statement two forces in each pair can either both act on the same body or they can act on different bodies is false.
