Explanation:
The question is not complete, here is the complete question
<em>"Beatrice and the Elevator Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is traveling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator.</em>
<em>1. . What question is Beatrice trying to answer?</em>
<em>2. What is one variable Beatrice could change in her investigation? What might she figure out if this
</em>
<em> variable was changed"</em>
1. Beatrice is trying to observe the influence of the elevator movement on her weight, Hence the question is<em> "will the elevator movement cause her weight to change"</em>
therefore moving upward the reading on the scale will increase
Reading=mg+ma
downward
Reading will reduce
Reading=mg-ma
2. The independent variable is the acceleration due to gravity g=9.81m/s^2
while the dependent variables are
i. The elevators acceleration
ii. Beatrice's mass
Answer:
assuming ur speaking about chemistry
c=frequency×wavelength
or
energy=frequency×h
I believe the answer is convection!
Answer:
"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).
Answer:
200 km/h²
Explanation:
<em>Use the formula:</em>
acceleration = (final velocity - initial velocity) ÷ time taken
final velocity = 40 km/h
initial velocity = 30 km/h
time taken = 0.05 hours
<em>Substitute (plug in) the values into the equation:</em>
acceleration = (40 - 30) ÷ 0.05
acceleration = 10 ÷ 0.05
acceleration = 200 km/h²
