Saturn has an orbital period of 29.46 years. In two or more complete sentences, explain how to calculate the average distance fr

bixtya [17]

For astronomical objects, the time period can be calculated using:
T² = (4π²a³)/GM
where T is time in Earth years, a is distance in Astronomical units, M is solar mass (1 for the sun)
Thus,
T² = a³
a = ∛(29.46²)
a = 0.67 AU
1 AU = 1.496 × 10⁸ Km
0.67 * 1.496 × 10⁸ Km
= 1.43 × 10⁹ Km

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizont

Scilla [17]

Answer:

$R_{max} = 51.84 m$

Explanation:

When we shoot the dart upwards the time taken by the dart to go straight up and again come back is given as

$t = 4.6 s$

here we can say

$\Delta y = 0 = v_i t + \frac{1}{2}at^2$

$0 = v_i t - \frac{1}{2}(9.8)t^2$

put t = 4.6 s then we have

$v_i = 22.54 s$

Now in order to find the maximum range we can say

$R = \frac{v^2 sin2\theta}{g}$

so in order to have maximum range we can say

$\theta = 45 degree$

$R_{max} = \frac{v^2}{g}$

$R_{max} = \frac{22.54^2}{9.8}$

$R_{max} = 51.84 m$

When we place a voltage of 4V across an unknown substance, 0.1A of current is seen to flow. If the material is Ohmic, how much v

Alex Ar [27]

Answer:

Voltage will be 100 volt

Explanation:

We have given current through the circuit i = 0.1 A

Power dissipated P = 10 W

We know that power dissipated through any resistive cirvuit is given by

$P=i^2R$ , here i is current and R is resistance

So $10=0.1^2\times R$

R =1000 ohm

Now according to ohm's law V = iR

So Voltage V = 0.1×1000 = 100 volt
