What is a neoplasm? a. another word for a malignant tumor b. a type of carcinoma that grows only in the mouth c. a benign swelling of epithelial cells d. any new and abnormal growth

A neoplasm is any uncontrolled growth of abnormal cells or tissues in the body.

This abnormal mass can be benign or malignant (carcinogenic).

Therefore, the correct option is D.

it is called kinetic energy

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
