The asteroid belt circles the sun between the orbits of Mars and Jupiter. One asteroid has a period of 5.4 earth years.

Ad libitum [116K]

Answer:

(a) Radius = 4.6 x 10^11 m

(b) speed = 16.96 km/s

Explanation:

Time period, T = 5.4 earth years

mass of sun, M = 1.989 x 10^30 kg

(a) Let the orbital radius is R.

use the formula of period

$T^2 = \frac{4 \pi^2 R^3}{G M}\\\\\left ( 5.4\times 365\times 24\times 3600 \right )^2 = \frac{4\times3.14\times 3.14\times R^3}{6.67\times10^{-11}\times 1.989\times 10^{30}}\\\\R = 4.6\times 10^{11} m$

(b) Let the speed is v.

$v=\frac{2 \pi\times R}{T}\\\\v=\frac{2\times 3.14\times 4.6\times 10^{11}}{5.4\times 365\times 24\times 3600}\\\\v = 16963.6 m/s =16.96 km/s$

if a metal object was cut on half how much heat will be required to raise both half to a specific temperature

il63 [147K]

suppose the mass of a metal object be m and its specific heat capacity be s, and, H joules of heat is required to raise its temperature by t degrees Celsius

Than H is given by relation, $H = mst$

Now if this object is cut in two half's, than mass of half part will also be half <em>i.e. </em>M/2

So heat required to heat the half part will be $= (\frac{m}{2}) st =\frac{mst}{2} = H/2$

Hence, the heat required to raise the half object to a specific temperature will also become half.

If your vehicle has a steering wheel lock, should you ever turn off the ignition while it is moving?

umka2103 [35]

It is not advisable to turn off the ignition while it is moving, so it is a no. Why? Even though the vehicle has steering wheel lock, turning off the ignition while it is moving is not advisable because it causes the vehicle to lose out of control, leading to complications and accidents.
