Answer:
ionic
Explanation:
ionic bond is when a metal and nonmetal are bonded together
metallic bond is when a two metal are bonded
covalent is nonmetal and nonmetal bond or idk
Answer:
Quads will have more energy
Explanation:
If the acceleration due to gravity increases from 9.81 to 15, then the velocity will increase as the rate of changing velocity i.e acceleration has increased from 9.81 to 15 m/s^2
With increase of velocity, the energy and force will also increase. Hence, the squad will require/have higher energy.
Answer:
120,000J
Corrected question;
In one hour, coal supplies 500 000 J of energy. The wasted energy amounts to 380 000 J. How much useful energy is produced in one hour?
Explanation:
Given;
Total energy Et = 500,000 J
Wasted Energy Ew = 380,000J
The amount useful energy is the amount of energy that is available for supply.
This can be derived by subtracting the wasted energy from the total energy.
Useful energy = Total Energy - wasted energy
Eu = Et - Ew
Substituting the given values;
Eu = 500,000J - 380,000
Eu = 120,000 J
The amount of useful energy produced in one hour is 120,000 J
A because that is the answer
Answer:
B 5580 W•hr
Explanation:
A Watt is a Volt times an Amp
3(12 V(155 A•hr)) = 5580 W•hr
