Answer:
V = 42187 m/s = 42.18 km/s
Explanation:
given data:
mass of sun is ![= 2\times 10^{30} kg](https://tex.z-dn.net/?f=%3D%202%5Ctimes%2010%5E%7B30%7D%20kg%20)
radius of earth orbit is ![1.5\times 10^{11} m](https://tex.z-dn.net/?f=1.5%5Ctimes%2010%5E%7B11%7D%20m)
minimum speed can be determined by using following formula
}
where G is ![\times 10^{-11}](https://tex.z-dn.net/?f=%5Ctimes%2010%5E%7B-11%7D)
Plugging all value to get desired value
![V =(\frac{2\times 6.674 \times 10^{-11}2\times 10^{30}}{1.5\times 10^{11}})^{1/2}](https://tex.z-dn.net/?f=V%20%20%3D%28%5Cfrac%7B2%5Ctimes%206.674%20%5Ctimes%2010%5E%7B-11%7D2%5Ctimes%2010%5E%7B30%7D%7D%7B1.5%5Ctimes%2010%5E%7B11%7D%7D%29%5E%7B1%2F2%7D)
V = 42187 m/s = 42.18 km/s
Answer:
Explanation:
Work required = q x V
where q is charge on electron and V is potential difference
= 1.6 x 10⁻¹⁹ x 12
= 19.2 x 10⁻¹⁹ J
ur answer is C) Bubbles formed in the magma when it was still in liquid form.
The new pressure of the air in the syringe is 1.5 atm.
<h3>What is the new pressure of the syringe?</h3>
The new pressure of the air in the syringe is calculated as follows assuming the temperature remains constant;
P2 = P1V1/V2
P2 = 1 * 60/40
P2 = 1.5 atmospheres
In conclusion, pressure varies inversely as volume.

Limiting reactants is the reactant that will be consumed first in a chemical reaction. in automobile, the primary reaction would be combustion reaction. the reactants would be oxygen and a fuel, since oxygen is readily available in the air, oxygen is not the limiting reactant. that is why fuel is always what we are monitoring in our automobiles, because it will dictates if the reaction can still occur or not.
