Answer:

8 years

Explanation:

We can solve the problem by using Kepler's third law, which states that the ratio between square of the orbital period and the cube of the orbital radius of any object revolving around the Sun is constant:

\frac{T_e^2}{r_e^3}=\frac{T_a^2}{r_a^3}

where:

T_e = 1 y is the orbital period of Earth

r_e is the orbital radius of Earth

r_a=2 r_e is the orbital radius of the asteroid (which is twice that of Earth)

T_a = ? is the orbital period of the asteroid

Substituting and re-arranging the equation, we find

T_a^2 = \frac{r_a^3}{r_e^3} T_e^2 = \frac{(2 r_e)^2}{r_e^3} T_e^2=8 \frac{r_e^3}{r_e^3} T_e^2=8 T_e^2 = 8 (1y)^2=8 y

so, the orbital period of the asteroid will be 8 years.

When a second student joins the first, the height difference between the liquid levels in the right and left pistons is 35 cm .
sleet_krkn [62]

Answer:

The mass of the second student is 20.180 Kg

Explanation:

When the mass is added on one piston, it causes a change in pressure on other piston.

The change in mass is calculated using the formula,

Δm=ρhA/g

The calculated radius of piston is 0.46 m.

Given h=35 cm= 0.35 m.

Assume ρ=850 kg/m^3

So Δm=850*0.35*π*(0.46)^2/9.8

    Δm=  20.180 Kg

Andrej [43]

Answer:

Replication

Explanation:

<em>The process of running multiple trials for each measurement during an experiment and finding the average is referred to as </em><em>replication.</em>

Replication is one of the attributes of good measurements/experiments because it reduces variability and increases the accuracy of the outcome. It also ensures that relevant statistical analysis can be carried out on the data collected via replicative measurements.
