Answer:
Th-234, Pa-234
Explanation:
In alpha decay, 2 protons and 2 neutrons are lost. So U-238 would become Th-234.
In beta decay, one neutron is turned into a proton. So Th-234 would become Pa-234.
Organelles that are present in both forms of eukaryotic cells are the following :
Nucleus
Endoplasmic Reticulum
Ribosomal units
Golgi apparatus
Lysosomes
Perixosomes
Mitochondrion
Cytoskeleton/Cytosol
Vacuole
Nucleolus
Plasma membrane
Microtubules/Microfilaments
All celluar functions corresponding to the organelles can be found in both plant and animal cells
I believe the answer would be A. because a magnet has both a south and a north pole, and electrical charges are formed by positive and negative forces. Hope I helped!
Answer:
"the plants had already started growing."
Explanation:
I think this is the answer because the definition of a dependent variable is the variable that is being affected by the change. Since the plants had already started growing BECAUSE of "They ran out of the farmer's compost, so
some of the plants received that compost
when the seeds were planted and other
plants got hardware store compost after
the plants had already started growing."
Sorry if I am wrong, I am just a 4th grader, pls don't hate on me, I am just trying to help :)
The change in momentum of the ball is D) 1.8 kg m/s
Explanation:
The change in momentum of the ball is given by:
where
m is the mass of the ball
v is the final velocity
u is the initial velocity
In order to calculate the change in momentum correctly, we have to correctly take into account the sign of the velocity. Taking the final direction of the ball as positive direction, we have:
u = -12 m/s is the initial velocity
v = +18 m/s is the final velocity (it changes sign because the direction has changed)
m = 0.060 kg is the mass of the ball
Solving the equation, we find the change in momentum of the ball:
