Momentum before collision must be equal to momentum after collision
(m1<span> + m</span>2)v = m1v1<span> + m</span>2v<span>2</span>
3.62g*270 m/s=2.30kg* (x)
convert the units to be the same that is convert the kg mass to grams
1kg=1000g
2.30kg=y
230/100*1000=2300g
3.62*270=2300X
977.4g/m/s=2300X
977.4/2300=0.4250M/S
Finding a velocity after the gun is embedded on the block of wood
3.62*270+2300g*0.425=(3.62+2300)*V
977.5+977.5=2303V
1955=2303V
V=1955/2303
V=0.8489M/S
Answer:
Person in the Control group: SpongeBob
Independent variable: Muscle cream
Dependent variable: Amount of muscle power
Larry's conclusion should conclude that the MUSCLE CREAM double a person’s muscle power when used as part of a muscle-building workout.
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the MUSCLE CREAM is the variable being changed for the groups i.e. Patrick and SpongeBob. Hence, the MUSCLE CREAM is the independent variable.
The dependent variable is the variable that responds to changes made to the independent variable. In this experiment, the dependent/responding variable is the AMOUNT OF MUSCLE POWER.
Control group is the group of an experiment that does not receive the experimental variable (muscle cream). In this experiment, the person that does not receive the experimental variable is SpongeBob i.e. was lathered with the regular lotion.
Larry, who is the one conducting the experiment, should conclude that MUSCLE POWER doubles a person’s muscle power when used as part of a muscle-building workout.
Answer: DNA polymerase and DNA ligase also are important in DNA replication. In addition to maintaining the integrity of DNA sequences by DNA repair, an accurate duplication of DNA is a prerequisite for all cell divisions.
Answer:
One might think of a plucked guitar string - the sound would depend on the original amplitude of the disturbance -
Speed and velocity would still be the same
(b) is correct because the energy transfer depends on the original energy applied.
