Answer:
D. Validity group
Explanation:
A validity group is not necessarily a component of a normal experiment.
A normal experiment is made up of the dependent variables, independent variables, and most times the control group.
- The dependent variable is one that relies on the outcome of the effect produced from the experimental design
- The independent variable is the one that causes a desired effect under the study.
- The control group is a group that does not receive any treatment nor attenuation of the conditions.
Answer:No
Explanation:
No
As the train is accelerating so train velocity will be more as compared to the ball and thus will cover more distance as compared to the ball.
When the ball is thrown upward with some velocity, it also possesses the train velocity at the time of throwing but as time passes velocity of train increases due to acceleration of the train. This causes the ball to fall behind the point of launch.
Answer:
In parallel combination, the cells are connected in such a way that the potential difference of the circuit is same as the cells used in the circuit but the time of current flowing increases
Answer:
around 50 miles per hour is the answer i believe :)
Explanation:
Answer:
254 meters (when rounded), assuming you don't count the updraft of the blades, possible wind, and air resistance.
Explanation:
Acceleration of gravity: 9.8 meters per second squared
Bag velocity: 70.56
Height: 254 meters
Initial Velocity: 0
