Answer:
c) The slope is not constant and increases with increasing time.
Explanation:
The equation for the position of this particle (starting from rest is)
We can take derivative of this with respect to time t to get the equation of slope:
As time t increase, the slope would increases with time as well.
Answer:
the speed of the nerve impulse in miles per hour is 201.59 mi/hr
Explanation:
Given;
the speed of the nerve impulse, v = 90.1 m/s
To convert this speed in meters per second to miles per hour, we use the following method;
1,609 meter = 1 mile
3,600 s = 1 hour
Therefore, the speed of the nerve impulse in miles per hour is 201.59 mi/hr
The momentum of the water balloon at the given speed is 7.2 kgm/s.
The given parameters:
- <em>Speed of the water balloon, v = 18 m/s</em>
- <em>Mass of the balloon, m = 0.4 kg</em>
The momentum of the water balloon is calculated as follows;
P = mv
<em>Substitute the given values of </em><em>mass </em><em>and </em><em>velocity </em><em>as follows;</em>
P = 0.4 x 18
P = 7.2 kg m/s.
Thus, the momentum of the water balloon at the given speed is 7.2 kgm/s.

Answer:
frequency
Explanation:
The phenomenon of apparent change in frequency due to the relation motion between the source and the observer is called Doppler's effect.
So, when we move farther, the frequency of sound decreases. The formula of the Doppler's effect is
where, v is the velocity of sound, vs is the velocity of source and vo is the velocity of observer, f is the true frequency. f' is the apparent frequency.
