Hi there!
Voltage in a series can be expressed by the following:
In words, the total voltage is equal to the sum of the individual voltage drops in a SERIES circuit.
We can solve for the total voltage:
In order to get a sample of air that is 23 km above the ground, the rocket must rise by that height.
Draw a diagram (shown below) t represent the problem.
The distance h₁ is traveled from A to B with an upward acceleration of 17 m/s² over 30 s. The distance traveled is
h₁ = (1/2)(17 m/s²)(30 s)² = 7650 m = 7.65 km
At point B, the velocity attained is
V = (17 m/s²)30s) = 510 m/s
The distance h₂ is traveled from B to C with gravitational deceleration of -9.8 m/s². The distance traveled is given by
(510 m/s)² - 2(9.8 m/s²)h₂ = 0
h₂ = 13270.4 m = 13.27 km
The total height attained by the rocket is
h₁ + h₂ = 7.65 + 13.27 = 20.92 km
This height falls short of the desired height of 23 km.
Answer:
The rocket does not travel high enough to sample the air at a height of 23 km.
Answer:
(a) 21.36 ohms
(b) 5.62 A
Explanation:
Parameters given:
Potential difference, V = 120 V
Power, P = 674 W
(a) Power is given as:
P = V²/R
Where R is resistance
=> R = V²/P
R = 120²/674
R = 14400/674
R = 21.36 ohms
(b) Power is also given as:
P = I*V
Where I = Current (time rate of flow of Electric charge)
=> I = P/V
I = 674/120
I = 5.62 A
Answer:
Forces observed by both is same as both
The frames are non-acceleration
Explanation:
Zweistein = Einstein
=
as tend to zero (0)
< as some quantity is subtracted from the force.
