Which of the following is a scalar? centripetal force weight speed acceleration

A scalar is one of the two types of measurements for scientists. The physical quantities they need to measure are classified into two categories: Scalars and vectors. Scalar quantities just have magnitude or size. Some examples of scalar quantities are temperature, mass (weight), energy for example joules, distance, speed for example meters per second and density for example kilograms per meter cubed.

Explanation:

A scalar is a measurement of quantity; it fully describes the magnitude and it is represented by a single number, some examples of scalar quantities are speed, volume, mass, temperature, power, energy and time.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
