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

Two equally charged, 1.00 g spheres are placed with 2.00 cm between their centers. when released, each begins to accelerate at 2

Leya [2.2K]

1) Force = m*a = 1.00 g * (1kg / 1000 g) * 225 m/s^2 = 0.225 N

2) Charge

Force = K (charge)^2 /(distance)^2 => charge = √ [Force * distance^2 / k]

k = 9.00 * 10^9 N*m^2 / C^2

charge = √ [0.225 N * (0.02 m)^2 / 9.00* 10^9 N*m^2 / C^2 ]

charge = 0.0000001 C = 0.0001 mili C

A professor drives off with his car (mass 870 kg), but forgot to take his coffee mug (mass 0.47 kg) off the roof. The coefficien

SSSSS [86.1K]

Answer: $6.86 m/s^2$

Explanation:

Given

mas of car=870 kg

coffee mug mass=0.47 kg

coefficient of static friction between mug and roof $\mu _s= 0.7$

Coefficient of kinetic Friction $\mu _k=0.5$

maximum car acceleration is $\mu \times g$

here coefficient of static friction comes in to action because mug is placed over car . If mug is moving relative to car then \mu _k is come into effect

$a_{max}=0.7\times 9.8=6.86 m/s^2$
