Answer:
(a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Explanation:
Given that,
Acceleration = 22.0 m/s²
Speed = 1.01 m/s
(a). We need to calculate the distance
Using equation of motion
Where, v = final speed
u = initial speed
a = acceleration
s = distance
Put the value into the formula
(b). We need to calculate the time
Using equation of motion
Put the value into the formula
Hence, (a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Answer:
A good conductor is copper because it conducts the energy flow of electrons easily.
Explanation:
Answer:
formula used K=F/∆l
∆l is the elongation of the spring
- F=10N
- ∆l=20mm===> 0.02m
- K=10N divided 0.02m= 500N/m
For the answer to the question above,
we can get the number of fringes by dividing (delta t) by the period of the light (Which is λ/c).
fringe = (delta t) / (λ/c)
We can find (delta t) with the equation:
delta t = [v^2(L1+L2)]/c^3
Derivation of this formula can be found in your physics text book. From here we find (delta t):
600,000^2 x (11+11) / [(3x10^8)^3] = 2.93x10^-13
2.93x10^-13/ (589x10^-9 / 3x10^8) = 149 fringes
This answer is correct but may seem large. That is because of your point of reference with the ether which is usually at rest with respect to the sun, making v = 3km/s.
Answer:
Yes
Explanation:
Accerelation is measured by change in velocity. So naturally, if an object is slowing down, its velocity is decreasing so acceleration is negative. If it is speeding up velocity is increasing so positive acceleration.
(Velocity final - Velocity initial)/t
Note that this does not apply only to gravity, but to all linear accelerations
