Answer:
The potential energy decreases
Explanation:
- When a proton moves in the direction of the electric field, the force on the proton (f=qE) will be in the direction of the field.
- The proton will accelerate and the KINETIC energy will increase.
- The potential energy decreases.
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:
The gravitational attraction between the two objects is
Explanation:
According to universal law of gravitation, the gravitational force of attraction acting between two objects will be directly proportional to the product of mass of the objects and inversely proportional to the square of the distance of separation of two objects.
Here G is the gravitational constant, M, m are the masses of the objects given as 6564300 kg and 5640 kg. And r is the distance of separation given as 50 m.
So
So the gravitational attraction of 0.988 mN will be acting between the two objects.
Answer:
The answer is mass .
Explanation:
The kinetic energy formula is :
So if the mass is higher, the kinetic energy gained is higher .
Piston<span> is the part in the combustion engine which moves up and down. Piston is connected in connecting rod which helps to move it.</span>
Spark plugs are used to produce spark.
<span>So the </span>answer is B. Piston
