Answer:
Using the data in the table scientists, students, and others that are familiar with the periodic table can extract information concerning individual elements. For instance, a scientist can use carbon's atomic mass to determine how many carbon atoms there are in a 1 kilogram block of carbon.

HOPE THIS HELPS LIKE AN RATE PLZ
Answer:
See the explanation below.
Explanation:
a)
Pumping water requires equipment with closed housing, so that water is not irrigated from the pumping point.
Fans in some applications do not require closed housings, as air irritation does not create anomalies or areas of nonconformity at the air pumping point.
b)
The pressures in water pumping equipment are usually much higher than those generated with air equipment, since the density of water is much higher than that of air, almost 1000 times higher.
Answer:
The work done is 
Explanation:
Work is defined as the product of force and distance moved in the direction of application of force.
Given Data
distance S= 230m
force F= 140 N
Mass of car m= 1140 kg
Applying the formula for work done we have
The work done by pushing the car for a distance of 
is
Answer:
rate of infusion is 900 mL/hr
Explanation:
given data
Infuse I1 = 1000 mL
delivers = 15 gtt/mL
Infuse I2 = 300 mL
time t= 20 min
rate = 60 mL/hr
to find out
rate of infusion
solution
we know here we give 300 mL infuse in 20 min
so here for 20 min
rate of infusion is express as
rate of infusion = I2 / t
rate of infusion = 300 / 20
rate of infusion = 15 mL / min
rate of infusion = 15 × 60 = 900
so rate of infusion is 900 mL/hr
Answer:
From question (a) and (b) the pendulum motion is perpendicular to the force so the normal force will do no work and the tension in the string of the pendulum will not work
And 
so
c
An example will be a where a stone is attached to the end of a string and is made to move in a circular motion while keeping the other end of the string in a fixed position
d
A dog walking along a surface which has friction, here the frictional force would acting in the direction of the motion and this would do positive work
