F=ma so,we have
f=300.3=900 N
but you should say 3 m/s^2
Answer:
D. A battery provides electrical energy to power a phone.
Explanation:
Examples of current electricity are starting a car, turning on a light, cooking on an electric stove, watching TV, shaving with an electric razor, playing video games, using a phone, charging a cell phone and more.
Answer:
2PBr₃ + 3Cl₂ → 2PCl₃ + 3Br₂
2Na + MgCl₂ → 2NaCl + Mg
Explanation:
A balanced chemical equation is a chemical equation that have an equal number of elements of each type on both sides of the equation
Among the given chemical reactions, we have;
2PBr₃ + 3Cl₂ → 2PCl₃ + 3Br₂
In the above reaction;
The number of phosphorus, P, on either side of the equation = 2
The number of bromine atoms, Br, on either side of the equation = 6
The number of chlorine atoms, Cl, on either side of the equation = 6
Therefore, the number of elements in the reactant side and products side of the reaction are equal and the reaction is balanced
The second balanced chemical reaction is 2Na + MgCl₂ → 2NaCl + Mg
In the above reaction, there are two sodium atoms, Na, one magnesium atom and two chlorine atoms on both sides of the reaction, therefore, the reaction is balanced
The circulation around the cylinder is 0.163Js/kg.
To find the answer, we have to know more about the stream flow.
<h3>
How to find the circulation around the cylinder?</h3>
, where d is the density at the sea level.
- We have the expression for lift per unit circulation as,
- Thus, the circulation around the cylinder is,
Thus, we can conclude that, the circulation around the cylinder is 0.163Js/kg.
