Best Answer

acceleration=(final velocity-initial velocity) divided by t

a=Δv/t

a=(63.9-5.56)/7.5

a=58.34/7.5

a=7.778666667≈7.8 meters per second squared (m/s2)

How many liters is 560 milliliters?

Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). Liters are three places to the left of milliliters. So you have to move the decimal place three times to the left. You will get 560 mL = .56 L.


How is electricity and magnetism similar?

Both are forms of energy according to the entropy approach published in my articles; [1]Abdelhady, S.," An Approach to a Universal System of Units" J. Electromagnetic Analysis & Applications", Vol. 2, No. 9, 2010: pp.549-556. [2] Abdelhady, S., "A Fundamental Equation of Thermodynamics that Embraces Electrical and Magnetic Potentials" J. Electromagnetic Analysis & Applications", Vol. 2, No. 3, 2010, pp. 162- 168. However; the electric charge is an electromagnetic wave that has an electric potential; positive or negative. Similarly; the magnetic flux as also an electromagnetic wave that a magnetic potential; left or right. So; both should be measured in Joule/volt.


What is 150 pounds converted to newtons?

Newtons is a measurement of force, and kilograms measures mass. In order to convert between the two you need some form of acceleration. Using Newtons law (F=ma) and assuming you are using gravity on earth, you would multiply 150 kg by 9.81 m/s^2 to get the force in Newtons.
