Answer:
110.7 J
Explanation:
Hooke's law is represented by the formula:
F = ke where F is the force in Newton, K is force constant and e is extension in m
work done = 1/2ke² = 1/2 K ( e² - e₀²) and e₀ is the extension at relaxed length
e₀ =0
work done = 0.5 × 82N/m × (2.70 m)² = 110.7 J
Answer:
4 : 1
Explanation:
<h3><u>Pulse rate</u></h3>
Also referred as heart rate can be affected due to vigorous exercise, age, health. Normally the pulse rate of an adult is between 60 to 100 beats per minute. pulse rate: 80 bpm.
<h3><u>Breathing rate</u></h3>
The amount of oxygen taken in inside of our body from the air. Breathing rate is usually affected due to age. Normal breathing rate of an adult is between 15 to 24 breaths per minute. breathing rate: 20 bpm.
<h3><u>Ratio of breathing to pulse rate</u></h3>
pulse rate : breathing rate
80 : 20
4 : 1
Answer:
69000 V
Explanation:
E = Electric field = 
d = Distance between plates = 2.3 cm
When we multiply the electric field strength and the distance between the plates of a capacitor we get the maximum voltage.
Maximum voltage is given by
The highest voltage the students can use is 69000 V
