Answer:
1.2 m/s
0.31 m
0.15 m
Explanation:
Time period is
Frequency is
Velocity is given by
The waves are traveling at 1.2 m/s
Amplitude is given by
Amplitude is 0.31 m
If d = 0.3 m
The amplitude would be 0.15 m. The speed would remain the same.
Answer:
.10/KWh
Explanation:
divide 606 by 61.37 and you get .1012...
Answer:
11.27N
Explanation:
Given parameters:
Mass of the book = 1.15kg
Unknown:
Magnitude of the normal force = ?
Solution:
The normal force is the vertical force exerted by a body on an object.
It can be described as the weight of an object.
Normal force = mass x acceleration due to gravity
Normal force = 1.15 x 9.8 = 11.27N
Do you need help with all of them
Answer:
see that the correct one is B
Explanation:
To solve this exercise let us use the kinematic relations
v² = v₀² - 2 a x
as they indicate that the car stops, therefore the final speed is yield v = 0
x = v₀² / 2a
let's calculate
x = 2²/(2 0.8)
x = 2.5 m / s²
When reviewing the answers we see that the correct one is B
