Answer: 1 000 times
Explanation: 1 000 centimetre is equal to 1 dekacemetre.
Using conversion will apply in converting every number.
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.
To calculate the average acceleration of the ball we use the formula,

Here,
is the final velocity of the ball and
is the initial velocity of the ball t is the time in contact with the wall.
Given
towards the wall and 
away from the wall and
.
Substituting these values in above formula , we get

Here
is negative because ball is moving away from the wall.

Therefore, average acceleration of the ball is
(away from the wall).
Answer:The total variation in the amount of light entering our eye is not dectiable therefore planets do not twinkle.
Explanation:Stars twinkle, while planets (usually) shine steadily. Why? Stars twinkle because … they're so far away from Earth that, even through large telescopes, they appear only as pinpoints. ... Planets shine more steadily because … they're closer to Earth and so appear not as pinpoints, but as tiny disks in our sky.As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
Answer:
28 moles of X.
Explanation:
Let's consider the complete combustion of ethanol.
C₂H₆O(l) + 3 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(l)
When 1 mole of ethanol burns it releases 1370 kJ, that is, the enthalpy of combustion is -1370 kJ/mol. If the energy released by one mole of etanol were used to syntesize the compound X, it would take 45.9 kJ to form 1 mole of X, that is, the enthalpy of formation is -49.5 kJ/mol. Then,
