Okay, I don't know if this question is supposed to be a trick question or not. The weight of the apple does not change as the plane travels up the atmosphere, but the MASS changes. Weight doesn't change no matter what environment you're in, but the mass changes in different environments. In this case, the weight is constant but the mass is decreasing as you go higher up.
Force is defined as Mass multiplied by Acceleration, or F = MA.
We have our mass, 15 kg.
We also have our acceleration, 8 m/s^2.
Let's plug in our numbers and solve.
F = 15(8)
Multiply 8 by 15.
8 • 15 = 120.
Your Force is 120.
Remember, the unit of measure for Force is Newtons (N).
Your final answer is:
120N.
I hope this helps!
Answer:
Total distance traveled= 75.36km (point at which she reaches her destination.)
Explanation:
With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:
First ride:
v=80km/h t=25min*1h/60min=0.42h
distancie= v*t = 80km/h * 0.42h =33.6km
Second ride:
v=65.0km/h t= 20min*1h/60min= 0.33h
distance= 65.0km/h*0.33h=21.67km
Stop: 60min= 1h distance=0km
third ride:
v= 40.0km/h t= 30.0min *1h/60min= 0.5h
distance= 40.0km/h*0.5h=20km
Total distance traveled= 33.6km +21.76km+20km
Total distance traveled= 75.36km
Correct answer is A.
In a parallel circuit, the voltage is same across all the branches however the current in each branch is different and depends on the resistance of that branch. The higher the resistance, the lower the current.
In a series circuit, the voltage across each resistive element is different and depends on the resistance of that element. Higher the resistance, larger will be the voltage drop. However, the current throughout the series circuit is the same as there is only path in a series circuit.
Points to Remember:
1) In series circuit current remains the same and voltage varies
2) In parallel circuit voltage remains the same and current varies
Answer:
r(b) = 2.45r
Explanation:
Parameters given:
Satellite A
Mass = m
Orbit radius = r
Satellite B
Mass = 6m
Orbit radius = r(b)
Gravitational force between Earth and Satellite A, F(A) is:
F(A) = (G*M*m)/r²
F(A) = GMm/r²
Gravitational force between Earth and Satellite B, F(B) is:
F(B) = (G*M*6m)/r(b)²
F(B) = 6GMm/r(b)²
Since F(A) = F(B),
GMm/r² = 6GMm/r(b)²
=> r(b)² = 6r²
r(b) = 2.45r
