Read the experiment setup. Then, match the components of the experiment with the type of variable. Marcy is doing an export lent on the effect of fertilizer on plant growth. She grows 30 pots of radishes. 10 pots receive fertilizer A, 10 pots receive fertilizer B, and 10 pots receive no fertilizer. She grows all the pots in the same location and gives them the same amount of water

a. ___: fertilizer
b. ___: plant growth
c. ___: growing in same location, water, type of plant (radish)

1. Independent variable
2. Dependent variable
3. Controlled variable

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
