Here's how I would do it:
How far does he have to go to catch the bug ? <u>23.8 meters</u>
How soon does he want to get there ? <u>1.8 seconds</u>
What speed does he need ? (23.8 m) / (1.8 sec) = <u>13.222 m/sec</u>
What speed is he flying now? <u>3.7m/s</u>
How much does he need to increase it ? (13.222 - 3.7) = <em>9.5 m/s</em> faster
Answer:
242.19702 N
578.46718 N
681.02785 N
Explanation:
M = Mass of the corresponding planet
r = Radius of the corresponding planet
g = Acceleration due to gravity = 9.81 m/s²
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Mass of person
Mass is the property of an object, it is constant irrespective of the forces acting on it so the mass of the person on each planet would be the same.
Gravitational force on Mars
Magnitude of the gravitational force Mars would exert on the man if he stood on its surface is 242.19702 N
Gravitational force on Venus
Magnitude of the gravitational force Venus would exert on the man if he stood on its surface is 578.46718 N
Gravitational force on Saturn
Magnitude of the gravitational force Saturn would exert on the man if he stood on its surface is 681.02785 N
A. 20m/s because the unit for velocity is m/s
<span> thermal energy which, by causing pressure and performing work on the pistons, is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy).</span>
a measurable variable and a subjective opinion.
Explanation:
Testable hypothesis that leads to experiments usually describes a relationship between a measurable variable and a subjective opinion.
In testing a hypotheses through experiments, we often design our work to suit the use of two variables which are the measurable variable and the subjective opinion.
- This often takes the shape of dependent and independent variables in an experiment.
- Measurable variables can either be dependent, independent or controlled variables.
- The subjective opinion is the scientific logic that governs hows two or more variables are related.
