Block A, with a mass of 50 kg, rests on a horizontal table top. The coefficient of static friction is 0.40. A horizontal string is attached to A and passes over a massless, ideal pulley as shown. What is the smallest mass of Block B that will start A movi...

A person has a choice while trying to move a crate across a horizontal pad of concrete: push it at a downward angle of 30 degrees, or pull it at an upward angle of 30 degrees. If the crate has a mass of 50.0 kg and the coefficient of friction between it a...

The rate constant of a first-order reaction is 4.25 x 10^-4 s^-1 at 350 Celsius. If the activation energy is 103 kJ/mol, calculate the temperature at which its rate constant is 8.75 x 10^-4 s^-1.

What is a mutation? a mutation is a change of a nucleotide sequence (AGTGCCATAA etc.) of the genome of an organism. How does this change the information in a DNA molecule? It changed the order of the nucleotide sequence. I.e. if you had a CTG sequence tha...

A person has a choice while trying to move a crate across a horizontal pad of concrete: push it at a downward angle of 30 degrees, or pull it at an upward angle of 30 degrees. a) Which choice is most likely to require less force on the part of the person?...

thanks Henry!

I got 17 Kelvin in the end. Does that mean my final answer will be 290 C (converted C to K)?

ah you are right DrBob222. I converted kJ to J.
