We have that

a) L1 = 0.0035600 km = We have this number has 5 significant figures

L2 = 136500 mm =We have this number has 3 significant figures

b) L1 = 0.0035600 km=3.65m

L2 = 136500 mm=136.5m

c) L1 is more accurate

d) L2 is more Precise

From the question we are told

Consider the following two values for measurements of length:

L1 = 0.0035600 km

L2 = 136500 mm

Generally

L1 = 0.0035600 km = We have this number has 5 significant figures

L2 = 136500 mm =We have this number has 3 significant figures

Express each number in proper scientific notation after converting the units to “meters”

L1 = 0.0035600 km=3.65m

L2 = 136500 mm=136.5m

Which of the two is more accurate

Generally

We define accuracy in measurement as the closes of a value measured to the actual value of

Therefore

L_1 is more accurate

We define Precision in measurement as how closely the reoccurring results are close

Therefore

L_2 is more Precise

luda_lava [24]

Answer:

Explanation:

The direction of force will be in upward direction making an angle of θ with the vertical .

Reaction force R = mg - F cosθ

Friction force = μR

= .36 (mg - F cosθ )

Horizontal component of applied force

= F sinθ

For equilibrium

F sinθ = .36 (mg - F cosθ)

F sinθ + .36 F cosθ =.36 mg

F (sinθ + .36 cosθ) = .36 mg

F R( cosδsinθ +sinδ cosθ) = .36 mg ( Rcosδ = 1 . Rsinδ= .36 )

F R sin( θ+δ ) = . 36 mg

F = .36 mg / Rsin( θ+δ )

For minimum F , sin( θ+δ ) should be maximum

sin( θ+ δ ) = sin 90

θ+ δ = 90

Rsinδ / Rcosδ = .36

δ = 20⁰

θ = 70⁰ Ans

Vanyuwa [196]

Answer:

The remaining percentage of drug concentration is about 88.7% 2 years after manufacture.

Explanation:

Recall the formula for the decay of a substance at an initial $N_0$ concentration at manufacture:

$N(t)=N_0\,e^{-k\,\,t}$

where k is the decay rate (in our case 0.06/year), and t is the elapsed time in years. Therefore, after 2 years since manufacture we have:

$N=N_0\,e^{-0.06\,\,(2)}\\N=N_0\,e^{-0.12}\\N/N_0=e^{-0.12}\\N/N_0=0.8869$

This in percent form is 88.7 %. That is, the remaining percentage of drug concentration is about 88.7% 2 years after manufacture.

Answer:2m/s²

Explanation: Well F=MA so sice F=4N and M=2kg let's plug in the values

4N=2KG*A

A=4N/2KG
