Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
Answer:
0.248 m
Explanation:
The period of a simple pendulum is given by
where
L is the length of the pendulum
g is the acceleration of gravity
The pendulum in the problem passes its lowest point twice every second: this means: this means that it makes one complete oscillation in one second, so its period is 1 second:
T = 1 s
And using
We can rearrange the equation above to find L, the length of the pendulum:
Answer:
B. The force due to gravity is 530 N. The force of air resistance is less than the force due to gravity.
Explanation:
Answer:
Kinetic energy is the energy an object has because of its motion.
Explanation:
ldk it's probably "object" that's all I know
