Answer:
Part a)
T = 3.96 s
Part b)
T = 1.98 s
Part c)
T = 2.8 s
Explanation:
As we know that time period of spring block system is given as
T = 2.8 s
Part a)
If the mass of the block attached is doubled
then we will have
Part b)
If the spring constant is doubled
then we have
Part c)
If the amplitude is halved but mass and spring constant will remain the same
so here we know that time period does not depends on Amplitude
so we will have
T = 2.8 s
Answer:
Mars.
Explanation:
It only has a little over 24 hours in a day, its rotation axis is tilted about the same as earths, and I MAY actually have some water on its surface.(Though none has been discovered YET)
Hope this helps lots and lots,
sincerely, me
Answer:
L = 0.24 m = 24 cm
Explanation:
Given:
- Wavelength of the wave λ = 12 cm
- total number of nodes : mode @ each end = 2 , 3 nodes in between = 5 nodes
Find:
How wide is the oven?
Solution:
- The wavelength of the microwave corresponds to a frequency of:
f = c / λ
f = 3.0*10^8 / 0.12
f = 25 * 10^8 Hz
- We have a total of 5 nodes, hence we get m = 4 anti-nodes in our standing wave.
- The frequency of a standing wave @ m of length L fixed at both ends is given by:
f_m = m*c / 2*L m = 1 , 2, 3 , 4, ....
L = m*c / 2*f_m
- Plug in values:
L = 4*3 / 2*25
L = 0.24 m = 24 cm
Answer:
because you need to tell the engine it needs to work faster
Explanation:
Answer:
v₀ = 49.5 miles / h
Explanation:
We can solve this exercise with kinematics in one dimension
v² = v₀² - 2 a d
let's apply this equation to the initial data, the fine velocity zero
0 = v₀² - 2 a d
a = v₀² / 2d
in the second case the distance is half (d´ = ½ d), the acceleration of the vehicle is the same, we look for the initial speed
0 = v₀´² - 2 a d´
v₀´² = 2 a d = 2 (v₀² / 2d) d´
v₀´ = v₀ √ 1/2
let's calculate
v₀´ = 70 ra 0.5
v₀ = 49.5 miles / h
