Answer:
The total resistance is 5000 N. So the net force left for acceleration is 7 000 N (12 000 - 5 000).
7000 N applied to 2x700 kg gives a maximum acceleration of
a = F/m = 7000/1400kg = 5 m/s^2
At 5m/s^2, it will take 8 s to reach 40 m/s. In 8 second the distance covered will be
d = 1/2 at^2 = 1/2 x 5 x 8^2 = 160 m
Because each glider has the same drag and inertia, the tension in the rope between the gliders will be exactly half of the tension between plane and the two gliders:
12 000/2 = 6 000N.
Answer:
The amount of time is 31.45 sec.
Explanation:
Given that,
Voltage = 10.0 V
Resistance
Capacitance
We need to calculate the time constant
Using formula of time constant
Put the value into the formula
The amount of time required for the current in the circuit to decay to 4.00% of its original value.
We need to calculate the amount of time
Using formula of charge
Put the value into the formula
Hence, The amount of time is 31.45 sec.
Answer: Option (d) is the correct answer.
Explanation:
Article's help people know about the advantages or disadvantages of the product or topic for which it is written.
Basically an article provides an overall scenario about a situation or thing so that readers can decide themselves whether they are in favor or against the thing on which article has been written.
Therefore, we can conclude that out of the given options, to get the reader to understand the two types of signals is most likely the author’s motive for writing the article.
Fireworks is a good example of chemical reaction. The color change and heat associated with fireworks result in chemical reactions. Chemical reactions can not be reversed. The correct option is C.
