Independent variable: the variable in an experiment which value is not changed based on any other variable. often denoted by "x"
dependent variable: the variable in an experiment which changes based on the value of the independent variable, ie how much of it you use, how often you use it, etc. often denoted by "y"

theory: an explanation as to why certain phenomena occur. supported and testable, but could change with new research / experiments, etc.
hypothesis: a guess or an estimate of what will happen during an experiment. testable, and may be wrong.

i hope this helps!!

If your front lawn is 18.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1050 new snow flakes every min
Ivanshal [37]
<span>First, we need to determine the entire area of your front line by multiplying its length times its width.
18.0*20.0 = 360.0 square feet
We can use the rate of accumulation of snow, combined with this figure, to determine how much snow accumulates on your lawn per minute.
360.0 sq ft * 1050 flakes/min/sq ft = 378,000 flakes/min
We can then use the mass of a snowflake to calculate total snow accumulation per minute.
378,000 flakes/min * 2.00 mg/flake = 756,000 mg/min
Finally, we can use this number to determine accumulation per hour.
756,000 mg/min * 60 min/hr =
45,360,000 mg/hr</span>

The length of second hand of clock is 14cm, an ant sits on the top of second hand. find the following
Anastaziya [24]

Answer:

The answer is below

Explanation:

i) Since the length of the second clock (radius) is 14 cm = 0.14 m, the distance covered by the second hand in one revelution is:

Distance covered = 2πr = 2π(0.14) = 0.88 m

The time taking to complete one revolution = 60 seconds, hence;

Speed = distance covered in one revolution / time take o complete a revolution

Speed = 0.88 m / 60 s = 0.0147 m/s

ii) Distance covered in 150 s = speed * 150 s = 0.0147 * 150 = 2.2 m

iii) Displacement in 150 seconds = distance from initial position to final position

At 150 s, the hand has covered 2 revolutions and moved 30 s. Hence:

Displacement in 150 seconds = speed * 30 s = 0.0147 * 30 = 0.44 m

A moon of mass 1×10^20kg is in a circular orbit around a planet. The planet exerts a gravitational force of 2×10^21n on the moon
vagabundo [1.1K]

Hi there!

In this instance, the centripetal force experienced by the moon is equivalent to the gravitational force.

Thus:
\large\boxed{F_c = F_g}

Centripetal acceleration, according to Newton's Second Law:


\Sigma F = ma \\\\F_c = m * a_c\\\\a_c = \frac{F_c}{m}

Therefore:

a_c = \frac{F_g}{m_m} = \frac{2 * 10^{21}N}{1 * 10^{20}kg} = \boxed{20 N/kg}
