Explanation:
The given data is as follows.
Distance (s) = 20 m
time (t) = 0.775 s
Also, it is given that mass per 1 meter length (m) = 0.300 kg
Formula to calculate the velocity is as follows.
Velocity (v) = 
Putting the given values into the above formula as follows.
v =
= 
= 25.80 m/s
We know that,
v = 
Taking square on both the sides, the formula will become as follows.
T = 
= 
= 199.692 N
Therefore, we can conclude that tension in the given tightrope is equal to 199.692 N
.
Answer:
6.3 m/s
Explanation:
m = mass of the block = 1.10 kg
k = spring constant of the spring
x = stretch in the spring = 0.2 m
t = time taken by block to come to zero speed first time = 0.100 s
T = Time period of oscillation
Time period of oscillation is given as
T = 2t
T = 2 (0.1)
T = 0.2 s
Time period is also given as
k = 1084.6 N/m
v = maximum speed of the block
using conservation of energy
Maximum kinetic energy = Maximum spring potential energy
(0.5) m v² = (0.5) k x²
m v² = k x²
(1.10) v² = (1084.6) (0.2)²
v = 6.3 m/s
Answer:
200 m / min
Explanation:
Total distance = 2000 m
Total time = 2+4+1+3 = 10 minutes
Average speed = 2000 m / 10 min = 200 m/min
So, basically, it might have different quantities, such as Carbon Dioxide (CO2) and Carbon Monoxide (CO), which are both made up of Carbon and Oxygen, but Carbon Monoxide has less oxygen. And they both have different properties, like CO is poisonous.
I believe Action potential is the brief wave of positive charge that sweeps down the axon. Axon is part of the neuron that conducts impulses from the dendrites towards the cell body along the neuron. The action potential is brief since the sodium channels can only stay open for a very brief amount of time. As it travels along the neuron there is a change in polarity across the membrane of the axon .
