Yasmine is trying to determine if her toy moves fast or slow. What can she do to help her decide? (2 points) Group of answer choices Calculate how long the toy travels. Compare the speed of her toy to another similar toy. Measure the distance her toy travels. Measure the duration the toy travels.

B. Compare the speed of her toy to another similar toy.

Explanation:

A body is said to be in motion when there is a change in position with respect to time. The speed of a body in motion is a measurement of distance to time. The formula is given thus;

Speed = Distance * Time

To accurately determine the fastness or slowness of a moving object, comparisons should be made, or a standard used to ascertain the truth. When a comparison is made with an object with similar characteristics, then it becomes easier to know which is moving faster or slower when the speeds are compared. An average can be obtained, and if the speed of the object being checked falls below average, then it is slow. If the speed is above average, then it is fast.

So, for Yasmine to know if her toy is moving fast or slow, she needs to compare hers with another similar toy.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
