According to the second law of motion, the force on a body is equal to the rate change of its momentum. On simplifying we get, F = ma. Therefore, Force = 5 x 7 = 35 N.

From the second law of motion we get that F = ma, when the mass is not changing. Putting in the units, we get, Newton = Kg-m/s².

The general expression for force is F = dp/dt. On solving we get, F = m(dv/dt) + v(dm/dt). Since the system is constant velocity, hence dv/dt = 0. What remains is F = v(dm/dt).

Disposing of waste has huge environmental impacts as a certain type of wastecan be hazardous and can contaminate the environment if not handled properly. Some waste generates methane gas, which contributes to the greenhouse effect.

Recycling is the most useful method for plastic waste disposal as several waste materials can be used as raw materials to manufacture useful products again.

Cellulose is an organic material derived from plants. Hence they are degraded in nature by microorganisms. They are deposited in landfills and are converted into compost.

Endocrine glands lack ducts and are hence, known as ductless glands. Their secretions are called hormones. As these glands do not have ducts, therefore they release their secretions directly into the bloodstream.

The hypothalamus is the basal part of the diencephalon, forebrain and it regulates a wide spectrum of body functions. It contains several groups of neurosecretory cells called nuclei which produce hormones.

The hormones produced by the hypothalamus are of two types:
i. Releasing hormones-which stimulate the secretion of pituitary hormones
ii. Inhibiting hormones-which inhibit the secretion of pituitary hormones.

The posterior pituitary is under the direct neural regulation of the hypothalamus. The pituitary gland is located in a bony cavity called Sella turcica and is attached to the hypothalamus by a stalk.
